5-1-1Benjamin Weiss, 'Talker Quality in Human and Machine Interaction - Modeling the Listener’s Perspective in Passive and Interactive Scenarios'. T-Labs Series in Telecommunication Services. Springer Nature, Cham. (2020)

Benjamin Weiss (2020): 'Talker Quality in Human and Machine Interaction - Modeling the Listener’s Perspective in Passive and Interactive Scenarios'. T-Labs Series in Telecommunication Services. Springer Nature, Cham.

In this book, the background, state of research, and own contributions to the assessment and prediction of talker quality that is constituted in voice perception and in dialog are presented. Starting from theories and empirical findings from human interaction, major results and approaches are transferred to the domain of human-computer interaction. The main subject of this book is to contribute to the evaluation of spoken interaction in both humans and between human and computer, and in particular to the quality subsequently attributed to the speaking system or person, based on the listening and interactive experience.

5-1-3Proceedings of SLTU-CCURL2020

Dear all,

we are very happy to announce that the SLTU-CCURL2020 Proceedings are available online:
This year, LREC2020 would have featured an extraordinary event: the first joint SLTU-CCURL2020 Workshop, which was planned as a two-day workshop, with 54 papers accepted either as oral and poster presentations.
The workshop program was enriched by two tutorials and two keynote speeches.
We will miss the presentations, the discussions and the overall stimulating environment very deeply. 
We are thankful to ELRA and ISCA for their support to the workshop, to our Google sponsor and to the 60 experts of the Program Committee, who worked tirelessly in order to help us to select the best papers representing a wide perspective over NLP, speech and computational linguistics addressing less-resource languages.
Looking forward to better times when we will be able to meet in person again, we hope that you will find these workshop proceedings relevant and stimulating for your own research.
With our best wishes,

Claudia Soria, Laurent Besacier, Dorothee Beermann, and Sakriani Sakti

5-1-4J.Blauert, J. Braasch, 'The Technology of Binaural Understanding', Springer and ASA-Press

 My name is Jens Blauert, and you may recall me as an ESCA-Founder and ISCA-Goldmedalist. Although I am professor emeritus since many years, I am still active in science.
     Recently I published an edited book together with Jonas Braasch (Professor at RPI, Troy NY) at both SPRINGER and ASA-Press. The book?s title is ?The Technology of Binaural Understanding?. It attempts to bridge between audition and cognition and thus, as far as speech communication is concerned, between speech and language. The book's motto is:

     People, when exposed to acoustic stimuli, do not react directly to what they hear
     but rather to what they hear means to them.

     Obviously this is an issue which is also relevant for speech communication at large. Thus, I kindly  ask you to consider whether this book would qualify for a book announcement in the ISCAPad. If a full book review were also feasible, I can send you an eBook-link, and after a reviewer is has been assigned, SPRINGER will deliver a printed copy to him/her.
--   Thank you for your efforts in advance!
     With best regards, Jens Blauert

30th Anniversary Highlight: Switchboard
Switchboard-1 Release 2 (LDC97S62) is considered the first large collection of spontaneous conversational telephone speech (Graff & Bird, 2000). It consists of approximately 260 hours of recordings collected by Texas Instruments in 1990-1991  (Godfrey et al., 1992). The first release of the corpus (later superseded) was published by NIST and distributed by LDC in 1993.

Participants were 543 speakers (302 male, 241 female) from across the United States who accounted for around 2,400 two-sided telephone conversations. A robot operator handled the calls, giving the caller appropriate recorded prompts, selecting and dialing another person (the callee) to take part in a conversation, introducing a topic for discussion, and recording the speech from the two subjects into separate channels until the conversation was finished. Roughly 70 topics were provided, of which about 50 were used frequently. Selection of topics and callees was constrained so that: (1) no two speakers would converse together more than once and (2) no one spoke more than once on a given topic.

This gold standard data set has been used for many HLT applications, including speaker identification, speaker authentication, and speech recognition. It is considered one of the most important benchmarks for recognition tasks involving large vocabulary conversational speech (Deshmukh et al., 1998) as well as a key resource for studying the phonetic properties of spontaneous speech (Greenberg et al., 1996). Annotation tasks based on Switchboard include discourse tags/speech acts, part-of-speech tagging and parsing, and sentiment analysis

The Switchboard series includes Switchboard Credit CardPhase IIPhase III, the Switchboard Cellular collection, and new recordings from 18 Switchboard participants in the 2013 Greybeard corpus.

All Switchboard corpora are available in the Catalog for licensing by Consortium members and non-members. Visit Obtaining Data for more information.

New publications:
Xi’an Guanzhong Object Naming is comprised of 15 hours of audio recordings from speakers of the Guanzhong dialect of Mandarin Chinese living in or near Xi’an in Shaangxi Province (China) naming objects that appeared in colored line drawings. The corpus was developed to support traditional and computer aided language documentation.

The collection was conducted from February-May 2021 using LanguageARC, a citizen science portal developed by LDC, from a closed volunteer community. Speakers were presented with images selected from the MultiPic dataset and were asked to record themselves naming the objects in the images.

Xi’an Guanzhong Object Naming is distributed via web download.

2022 Subscription Members will automatically receive copies of this corpus. 2022 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for $250.


MASRI Synthetic MASRI (Maltese Automatic Speech Recognition I) Synthetic was developed by the MASRI team at the University of Malta and contains 99 hours of synthesized Maltese speech.

Source sentences were extracted from the Maltese Language Resource Server (MLRS) corpus, comprised of written or transcribed Maltese covering various genres, including parliamentary debates, news, law, opinion, sports, culture, academic, literature, and religious texts. Text was processed through the CrimsonWing text-to-speech system to generate speech files. Synthesized speech was created with 210 voices (105 female, 105 male).

MASRI Synthetic is distributed via web download.

2022 Subscription Members will automatically receive copies of this corpus provided they have submitted a completed copy of the special license agreement. 2022 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for $250.

5-2-4Google 's Language Model benchmark
 Here is a brief description of the project.

'The purpose of the project is to make available a standard training and test setup for language modeling experiments.

The training/held-out data was produced from a download at using a combination of Bash shell and Perl scripts distributed here.

This also means that your results on this data set are reproducible by the research community at large.

Besides the scripts needed to rebuild the training/held-out data, it also makes available log-probability values for each word in each of ten held-out data sets, for each of the following baseline models:

  • unpruned Katz (1.1B n-grams),
  • pruned Katz (~15M n-grams),
  • unpruned Interpolated Kneser-Ney (1.1B n-grams),
  • pruned Interpolated Kneser-Ney (~15M n-grams)


Happy benchmarking!'


5-2-5Forensic database of voice recordings of 500+ Australian English speakers

Forensic database of voice recordings of 500+ Australian English speakers

We are pleased to announce that the forensic database of voice recordings of 500+ Australian English speakers is now published.

The database was collected by the Forensic Voice Comparison Laboratory, School of Electrical Engineering & Telecommunications, University of New South Wales as part of the Australian Research Council funded Linkage Project on making demonstrably valid and reliable forensic voice comparison a practical everyday reality in Australia. The project was conducted in partnership with: Australian Federal Police,  New South Wales Police,  Queensland Police, National Institute of Forensic Sciences, Australasian Speech Sciences and Technology Association, Guardia Civil, Universidad Autónoma de Madrid.

The database includes multiple non-contemporaneous recordings of most speakers. Each speaker is recorded in three different speaking styles representative of some common styles found in forensic casework. Recordings are recorded under high-quality conditions and extraneous noises and crosstalk have been manually removed. The high-quality audio can be processed to reflect recording conditions found in forensic casework.

The database can be accessed at:

5-2-7EEG-face tracking- audio 24 GB data set Kara One, Toronto, Canada

We are making 24 GB of a new dataset, called Kara One, freely available. This database combines 3 modalities (EEG, face tracking, and audio) during imagined and articulated speech using phonologically-relevant phonemic and single-word prompts. It is the result of a collaboration between the Toronto Rehabilitation Institute (in the University Health Network) and the Department of Computer Science at the University of Toronto.


In the associated paper (abstract below), we show how to accurately classify imagined phonological categories solely from EEG data. Specifically, we obtain up to 90% accuracy in classifying imagined consonants from imagined vowels and up to 95% accuracy in classifying stimulus from active imagination states using advanced deep-belief networks.


Data from 14 participants are available here:

PAPER Shunan Zhao and Frank Rudzicz (2015) Classifying phonological categories in imagined and articulated speech. In Proceedings of ICASSP 2015, Brisbane Australia

ABSTRACT This paper presents a new dataset combining 3 modalities (EEG, facial, and audio) during imagined and vocalized phonemic and single-word prompts. We pre-process the EEG data, compute features for all 3 modalities, and perform binary classi?cation of phonological categories using a combination of these modalities. For example, a deep-belief network obtains accuracies over 90% on identifying consonants, which is signi?cantly more accurate than two baseline supportvectormachines. Wealsoclassifybetweenthedifferent states (resting, stimuli, active thinking) of the recording, achievingaccuraciesof95%.

5-2-11JLCorpus - Emotional Speech corpus with primary and secondary emotions
JLCorpus - Emotional Speech corpus with primary and secondary emotions:

For further understanding the wide array of emotions embedded in human speech, we are introducing an emotional speech corpus. In contrast to the existing speech corpora, this corpus was constructed by maintaining an equal distribution of 4 long vowels in New Zealand English. This balance is to facilitate emotion related formant and glottal source feature comparison studies. Also, the corpus has 5 secondary emotions along with 5 primary emotions. Secondary emotions are important in Human-Robot Interaction (HRI), where the aim is to model natural conversations among humans and robots. But there are very few existing speech resources to study these emotions,and this work adds a speech corpus containing some secondary emotions.

Please use the corpus for emotional speech related studies. When you use it please include the citation as:

Jesin James, Li Tian, Catherine Watson, 'An Open Source Emotional Speech Corpus for Human Robot Interaction Applications', in Proc. Interspeech, 2018.

To access the whole corpus including the recording supporting files, click the following link:, (if you have already installed the Kaggle API, you can type the following command to download: kaggle datasets download -d tli725/jl-corpus)

Or if you simply want the raw audio+txt files, click the following link:

The corpus was evaluated by a large scale human perception test with 120 participants. The link to the survey are here- For Primary emorion corpus:

For Secondary emotion corpus:

These surveys will give an overall idea about the type of recordings in the corpus.

The perceptually verified and annotated JL corpus will be given public access soon.

OPENGLOT –An open environment for the evaluation of glottal inverse filtering


OPENGLOT is a publically available database that was designed primarily for the evaluation of glottal inverse filtering algorithms. In addition, the database can be used in evaluating formant estimation methods. OPENGLOT consists of four repositories. Repository I contains synthetic glottal flow waveforms, and speech signals generated by using the Liljencrants–Fant (LF) waveform as an excitation, and an all-pole vocal tract model. Repository II contains glottal flow and speech pressure signals generated using physical modelling of human speech production. Repository III contains pairs of glottal excitation and speech pressure signal generated by exciting 3D printed plastic vocal tract replica with LF excitations via a loudspeaker. Finally, Repository IV contains multichannel recordings (speech pressure signal, EGG, high-speed video of the vocal folds) from natural production of speech.

5-2-20ELRA announces that MEDIA data are now available for free for academic research

ELRA announces that MEDIA data are now available for free for academic research

Further to the request of the HLT French community to foster evaluation activities for man-machine dialogue systems for French language, ELRA has decided to provide a free access to the MEDIA speech corpora and evaluation package for academic research purposes.

The MEDIA data can be found in the ELRA Catalogue under the following references:

Data available from the ELRA Catalogue can be obtained easily by contacting ELRA.  

The MEDIA project was carried out within the framework of Technolangue, the French national research programme funded by the French Ministry of Research and New Technologies (MRNT) with the objective of running a campaign for the evaluation of man-machine dialogue systems for French. The campaign was distributed over two actions: an evaluation taking into account the dialogue context and an evaluation not taking into account the dialogue context.

PortMedia was a follow up project supported by the French Research Agency (ANR). The French and Italian corpus was produced by ELDA, with the same paradigm and specifications as the MEDIA speech database but on a different domain.

5-2-21ELRA/ELDA Communication : LT4all

Out of the 7,000+ language spoken around the world, only a few have associated Language Technologies. The majority of languages can be considered as 'under-resourced' or as 'not supported'. This situation, very detrimental to many languages speakers, and specifically indigenous languages speakers, creates a digital divide,  and places many languages in danger of digital extinction, if not complete extinction.

Organized as part of the 2019 International Year of Indigenous Languages, the 1st edition of LT4All (Language Technologies for All: Enabling Linguistic Diversity and Multilingualism Worldwide) took place in Paris at the UNESCO Headquarters on December 4-6, 2019 and gathered 400 participants from various backgrounds (including language science and technology researchers, linguists, industrials, indigenous peoples, language policy and decision makers) from all over the world.

The LT4All Programme and Editorial Committees are very happy to announce that the set of Research Papers and Posters collected at the occasion of LT4All is now available online at :

LT4All has  been made possible thanks to the close cooperation between UNESCO, the  Government of the Khanty-Mansiysk Autonomous Okrug-Ugra (Russian Federation), the European Language Resources Association (ELRA) and its Special Interest  Group on Under-resourced  languages  (SIGUL), and in partnership with UNESCO Intergovernmental Information for All Programme (IFAP) and the Interregional Library Cooperation Centre, as well as with support of other public organizations and sponsors.

Search and Find ELRA LRs on Google Dataset Search and ELG LT Platform

ELRA is happy to announce that all the Language Resources from its Catalogue can now be searched and found on Google Dataset Search and on the ELG Language Technology platform developed within the European Language Grid project.

In order to allow the indexing by Google Dataset Search, ELRA has updated the code generating the catalogue pages. The code developed follows the standard and is publicly available in JSON format so that it can be used for other harvesting purposes.

The ELRA Catalogue is already indexed and harvested by famous repositories and archives such as OLAC (Open Language Archives Community), CLARIN Virtual Language Observatory and META-SHARE.

For 25 years now, ELRA has been distributing Language Resources to support research and development in various fields of Human Language Technology. The indexing on both Google Dataset Search and the ELG LT Plaform is increasing ELRA Catalogue?s visibility, making the LRs known to new visitors from the Human Language Technologies, Artificial Intelligence and other related fields.

5-2-23Sharing language resources (ELRA)

ELRA recognises the importance of sharing Language Resources (LRs) and making them available to the community.

Since the 2014 edition of LREC, the Language Resources and Evaluation Conference, participants have been offered the possibility to share their LRs (data, tools, web-services, etc.) when submitting a paper, uploading them in a special LREC repository set up by ELRA.

This effort of sharing LRs, linked to the LRE Map initiative ( for their description, contributes to creating a common repository where everyone can deposit and share data.

Despite the cancellation of LREC 2020 in Marseille, a high number of contributions was submitted and the LREC initiative 'Share your LRs' could be conducted to the end successfully.

Repositories corresponding to each edition of the conference are available here:

5-2-24The UCLA Variability Speaker Database

With NSF support, our interdisciplinary team of voice research at UCLA recently put together a public database that we believe will be of interest to many members of the ISCA community. On behalf of my co-authors (Patricia Keating, Jody Kreiman, Abeer Alwan, Adam Chong), I'm writing to ask if we could advertise our database in the ISCA newsletter. We'd really appreciate your help with this.

The database, the UCLA Variability Speaker Database, is freely available through UCLA's Box cloud, which can be accessed from our lab website: I should mention that the database will also be available from the Linguistic Data Consortium (LDC) as of October, 2021.
Here's a brief description of the database.
The UCLA Variability Speaker Database comprises high-quality audio recordings from 202 speakers, 101 men 
and 101 women, performing 12 brief speech tasks in English over three recording sessions (total amount 
of speech: 300-450 sec per speaker). This public database was designed to sample variability in speaking 
within individual speakers and across a large number of speakers. The large set of speakers (similar in age) 
sampled from the current university community is gender-balanced and has a variety of language backgrounds. 
The database can serve as a testing ground for research questions involving between-speaker variability, 
within-speaker variability, and text-dependent variability. 
More details about the database are available in a readme file that can be sent on request.

5-3-1Cantor Digitalis, an open-source real-time singing synthesizer controlled by hand gestures.

We are glad to announce the public realease of the Cantor Digitalis, an open-source real-time singing synthesizer controlled by hand gestures.

It can be used e.g. for making music or for singing voice pedagogy.

A wide variety of voices are available, from the classic vocal quartet (soprano, alto, tenor, bass), to the extreme colors of childish, breathy, roaring, etc. voices.  All the features of vocal sounds are entirely under control, as the synthesis method is based on a mathematic model of voice production, without prerecording segments.

The instrument is controlled using chironomy, i.e. hand gestures, with the help of interfaces like stylus or fingers on a graphic tablet, or computer mouse. Vocal dimensions such as the melody, vocal effort, vowel, voice tension, vocal tract size, breathiness etc. can easily and continuously be controlled during performance, and special voices can be prepared in advance or using presets.

Check out the capabilities of Cantor Digitalis, through performances extracts from the ensemble Chorus Digitalis:

In pratice, this release provides:
  • the synthesizer application
  • the source code in the form of a Max package (GPL-like license)
  • a documentation for the musician and another for the developper
What do you need ?
  • a Mac OSX
  • ideally a Wacom graphic tablet, but it also works with your computer mouse
  • for the developers, the Max software

5-3-2MultiVec: a Multilingual and MultiLevel Representation Learning Toolkit for NLP


We are happy to announce the release of our new toolkit “MultiVec” for computing continuous representations for text at different granularity levels (word-level or sequences of words). MultiVec includes Mikolov et al. [2013b]’s word2vec features, Le and Mikolov [2014]’s paragraph vector (batch and online) and Luong et al. [2015]’s model for bilingual distributed representations. MultiVec also includes different distance measures between words and sequences of words. The toolkit is written in C++ and is aimed at being fast (in the same order of magnitude as word2vec), easy to use, and easy to extend. It has been evaluated on several NLP tasks: the analogical reasoning task, sentiment analysis, and crosslingual document classification. The toolkit also includes C++ and Python libraries, that you can use to query bilingual and monolingual models.


The project is fully open to future contributions. The code is provided on the project webpage ( with installation instructions and command-line usage examples.

5-3-3An android application for speech data collection LIG_AIKUMA
We are pleased to announce the release of LIG_AIKUMA, an android application for speech data collection, specially dedicated to language documentation. LIG_AIKUMA is an improved version of the Android application (AIKUMA) initially developed by Steven Bird and colleagues. Features were added to the app in order to facilitate the collection of parallel speech data in line with the requirements of a French-German project (ANR/DFG BULB - Breaking the Unwritten Language Barrier). 
The resulting app, called LIG-AIKUMA, runs on various mobile phones and tablets and proposes a range of different speech collection modes (recording, respeaking, translation and elicitation). It was used for field data collections in Congo-Brazzaville resulting in a total of over 80 hours of speech.
Users who just want to use the app without access to the code can download it directly from the forge direct link: 
Code is also available on demand (contact and
More details on LIG_AIKUMA can be found on the following paper:

5-3-6LIG-Aikuma running on mobile phones and tablets


Dear all,

LIG is pleased to inform you that the website for the app Lig-Aikuma is online:
In the same time, an update of Lig-Aikuma (V3) was made available (see website).      

LIG-AIKUMA is a free Android app running on various mobile phones and tablets. The app proposes a range of different speech collection modes (recording, respeaking, translation and elicitation) and offers the possibility to share recordings between users. LIG-AIKUMA is built upon the initial AIKUMA app developed by S. Bird & F. Hanke (see  for more information)

Improvements of the app:

  • Visual upgrade:
    + Waveform visualizer on the Respeaking and Translation modes (possibility to zoom in/out the audio signal)
    + File explorer included in all modes, to facilitate the navigation between files
    + New Share mode to share recordings between devices (by Bluetooth, Mail, NFC if available)
    + French and German languages available. In addition to English, the application now supports French and German languages. Lig-Aikuma uses by default the language of the phone/tablet.
    + New icons, more consistent to discriminate all type of files (audio, text, image, video)
  • Conceptual upgrade:
    + New name for the root project: ligaikuma ?> /! Henceforth, all data will be stored into this directory instead of ?aikuma? (in the previous versions of the app). This change doesn?t have compatibility issues. In the file explorer of the mode, the default position is this root directory. Just go back once with the left grey arrow (on the lower left of the screen) and select the ?aikuma? directory to access to your old recordings
    + Generation of a PDF consent form (from informations filled in the metadata form) that can be signed by linguist and speaker thanks to a pdf annotation tool (like Adobe Fill & Sign mobile app)
    + Generation of a CSV file which can be imported in Elan software: it will automatically create segmented tier, as it was done during a respeaking or a translation session. It will also mention by a ?non-speech? label that a segment has no speech.
    + Géolocalisation of the recordings
    + Respeak an elicit file: it is now possible to use in Respeaking or Translation mode an audio file initially recorded in Elicitation mode
  • Structural upgrade:
    + Undo button on Elicitation to erase/redo the current recording
    + Improvement session backup on Elicitation
    + Non-speech button in Respeaking and Translation modes to indicate by a comment that the segment does not contain speech (but noise or silent for instance)
    + Automatic speaker profile creation to quickly fill in the metadata infos if several sessions with a same speaker
Best regards,

Elodie Gauthier & Laurent Besacier

5-3-7Python Library
Nous sommes heureux d'annoncer la mise à disposition du public de la
première bibliothèque en langage Python pour convertir des nombres écrits en
français en leur représentation en chiffres.
L'analyseur est robuste et est capable de segmenter et substituer les expressions
de nombre dans un flux de mots, comme une conversation par exemple. Il reconnaît les différentes
variantes de la langue (quantre-vingt-dix / nonante?) et traduit aussi bien les
ordinaux que les entiers, les nombres décimaux et les séquences formelles (n° de téléphone, CB?).
Nous espérons que cet outil sera utile à celles et ceux qui, comme nous, font du traitment
du langage naturel en français.
Cette bibliothèque est diffusée sous license MIT qui permet une utilisation très libre.

5-3-8Evaluation des troubles moteurs de la parole MONPAGE version 2.0.s

Chères et chers collègues,  

Après plusieurs années de travail, nous avons le plaisir de vous annoncer la mise en ligne du protocole d?évaluation des troubles moteurs de la parole MONPAGE, version 2.0.s, à présent normalisé et validé.

Cet outil, mis librement à disposition de la communauté, est destiné à l?évaluation clinique des troubles moteurs de la parole légers à modérés (dysarthries et apraxies de la parole) chez l?adulte francophone. Il a été élaboré par un groupe de chercheurs et cliniciens belges, suisses, français et québécois. Il s?agit d?une batterie d?évaluation de la parole comprenant une passation informatisée (avec enregistrement des productions des patients) et des analyses perceptives et acoustiques semi-automatiques. Sa prise en main nécessite un minimum de compétences en phonétique acoustique.

Vous trouverez la présentation, les références, les ressources et les liens de téléchargement de MonPaGe-2.0.s sur le site :
Nous recommandons de commencer la prise en main en lisant le manuel de l'utilisateur.

N'hésitez pas à diffuser l'information!

5-3-9VocalTractLab3D: articulatory synthesis software.

Bonjour à tous,


Je vous informe par ce mail que le logiciel de synthèse articulatoire VocalTractLab3D est maintenant en ligne et à la disposition de tous librement:


VocalTractLab est un logiciel de synthèse articulatoire développé principalement par Peter Birkholz à la chaire de technologies de la parole et systèmes cognitifs de l’université de Dresde.


Au cours de mon postdoc j’ai travaillé à développer une version spéciale, VocalTractLab3D, qui inclut des simulations acoustiques 3Ds efficaces pilotées par une interface graphique.

Contrairement aux simulations acoustiques couramment utilisées dans l’étude de la parole, qui reposent sur une approche 1D basée sur la function d’aire, les simulations 3Ds décrivent le champ acoustique dans toutes les dimensions de l’espace et prennent en compte la forme 3D précise du conduit vocal.

Elles sont de fait plus précises, en particulier en haute fréquence (à partir d’environ 2-3 kHz).

Leur limitation est cependant le temps de calcul. Dans notre projet nous avons travaillé à repousser cette limite et notre logiciel permet de réaliser ce type de simulation dans un temps raisonnable (environ 1 heure pour une géométrie statique avec une solution précise).


Une autre limitation courante des simulations 3Ds est la nécessité de maitriser des methods de simulations assez techniques tells que les éléments finis, différences finies ou autres. Cela passe souvent par l’utilisation d’un language de programmation.

Nous avons également travaillé à repousser cette limite pour rendre accessible ce type de simulation au plus grand nombre: dans VocalTractLab3D ces simulations sont pilotées par une interface graphique et il n’est pas nécessaire de comprendre exactement comment fonctionne la méthode pour pouvoir calculer des fonctions de transfert ou des champs acoustiques.


Si suffisamment de personnes sont intéressées, je peux faire une présentation en ligne du logiciel, pour expliquer plus en detail en quoi il consiste, à quoi il peut servir et comment l’utiliser.

Ecrivez-moi si cela vous intéresse.


N’hésitez pas également à me contacter si vous avez des questions par rapport à ce logiciel.


Bien à vous,


Rémi Blandin
