2-1Message from ISCA president Prof. Sebastian Möller



Dear friends of ISCA,


As I am writing these words, INTERSPEECH 2022 has just closed its doors. Considering that it was the first INTERSPEECH conference since the beginning of the pandemic with a substantial in-person presence, it is indeed an enormous success that the organizers attracted close to 1600 in-person participants, plus approx. 700 virtual participants, to our major community event. With a record number of submissions, it was also able to feature an excellent scientific program, compiled by the TPC Chairs Kyogu Lee, Lori Lamel, Mark Hasegawa-Johnson, Karen Livescu and Okim Kang, with the support of many Area Chairs and even more reviewers. To this already top-level program were added four keynotes – one by our ISCA medalist Lin-Shan Lee, six survey talks, eight tutorials, and 12 special sessions, as well as industry talks, satellite events and many student- and postdoc-organized events. On behalf of ISCA and the entire membership, I would like to thank our General Chair Hanseok Ko, as well as our General Co-Chair John H.L. Hansen, for their efforts in making this major event a great success!


The special setting of INTERSPEECH 2022 has highlighted significant challenges we as a scientific association are facing. One such challenge is the effort which organizers can put into hybrid set-ups. Audio-visual equipment enabling interactive participation for virtual participants has been found to be too costly to be established for all sessions. The ISCA Advisory Council has also stressed that the primary focus for INTERSPEECH organizers should be on in-person participation; thus, virtual participants will – for the time being – have to live with reduced interactive offers if we want to keep participation fees accessibly low. A second challenge is the large number of submissions (with 2140 papers undergoing review this year), and the resulting necessity for a substantial pool of qualified reviewers. We thus rely on all of your expertise to ensure the high quality of our scientific program, and encourage you to subscribe to our reviewer database at (if you have not yet done so). A third challenge is the management of such a high number of papers and reviewers within a short period of time. We envisage a move to a different paper management system in the near future, in order to achieve the best-possible matches between papers and reviewers, as well as to take advantage of additional functionalities for the TPC and Area Chairs.


Lastly, I would like to remind you about the workshop that several past ISCA presidents will organize in honor of Sadaoki Furui, on November 29, 2022; see the ISCA front page for more details.


I wish you all a good read of this ISCApad, as usual excellently compiled by Chris Wellekens.

2-2Professor Sadaoki Furui's obituary (1945-2022)
 Sadaoki Furui (1945-2022)


It is with great sadness that we announce the passing of one of the great pioneers and creative geniuses of speech processing, Dr. Sadaoki Furui. Sadaoki was born in 1945 in Tokyo, and passed away on 31st July 2022 at the age of 76. He is survived by his wife Hikaru, to whom he was dearly dedicated for 51 years, and by his loving daughters, Miyuki and Nozomi. Sadaoki earned the B.S., M.S., and Ph.D. degrees in Mathematical Engineering and Instrumentation Physics from the University of Tokyo in 1968, 1970, and 1978 respectively.


After joining the Nippon Telegraph and Telephone Corporation (NTT) Labs in 1970, Sadaoki worked on speech analysis, speech recognition, speaker recognition, speech synthesis, speech perception, and multimodal human-computer interaction. From 1978 to 1979, he was a Visiting Researcher at AT&T Bell Laboratories, Murray Hill, New Jersey. He was a Research Fellow and the Director of the Furui Research Laboratory at NTT Labs, and a Professor at the Department of Computer Science, Tokyo Institute of Technology. He was President of the Toyota Technical Institute at Chicago from 2013 to 2019. Most recently, he was Chief Research Director at the National Institute of Informatics in Tokyo, and Professor Emeritus at the Tokyo Institute of Technology.


Sadaoki was a pioneer in the field of computer-based speech recognition, understanding, and speaker recognition. Many of his research results are truly original. His investigation into the human perception of transient sounds presented the first quantifiable measurement of the importance of spectral transition on the intelligibility of speech. His results also led to the innovative idea of computing spectral derivatives for use in speech and speaker recognition systems to improve recognition accuracy. Today, spectral derivatives, or the so-called ‘delta cepstrum’ parameters, are key components in the feature set that characterizes a speech pattern for automatic recognition by machine, and most contemporary practical speech and speaker recognition systems use delta cepstrum parameters. Likewise, the delta cepstrum also plays an important role in HMM (hidden Markov model)-based speech synthesis which has been actively investigated and used in many applications all over the world.


Sadaoki was one of the first researchers to investigate the recognition of spontaneous speech, and he led the project that collected the Corpus of Spontaneous Japanese (CSJ), the world's largest and most representative database of spontaneous speech. CSJ became a core resource for analyzing the nature of spontaneous speech and for developing a speech recognition methodology for “natural” speech. As a result, the recognition accuracy of spontaneous speech, which up to that time had proven extremely poor, was greatly improved.


Sadaoki was a researcher and educator: he published over 1000 scientific papers, six textbooks, one edited book, and two translated books. He has particularly contributed to the education of young researchers, and many have learned speech processing by reading his well-known textbook “Digital Speech Processing, Synthesis, and Recognition”. He has also served extensively as a lecturer in many organizations, for example as IEEE and ISCA Distinguished Lecturer. As president of Toyota Technological Institute of Chicago, he was responsible for educating talented researchers in the machine learning field including signal processing.


Sadaoki served as President of the International Speech Communication Association (ISCA) from 2001 to 2005, and actively promoted the collaboration between speech science and speech technology. He also served as President of the Acoustical Society of Japan from 2001 to 2003, and founded the Asia-Pacific Signal and Information Processing Association (APSIPA) to contribute to promoting signal and information processing research activities in the Asia-Pacific region, serving as its first president.


Sadaoki received many professional awards and honors including the Paper Award and the Achievement Award from the Institute of Electronics, Information, and Communication Engineers of Japan (IEICE) (1975, 1988, 1993, 2003, 2003, 2008), and the Paper Award from the Acoustical Society of Japan (ASJ) (1985, 1987). He received the Senior Award and Society Award from the IEEE Signal Processing Society (1989, 2006), the International Speech Communication Association (ISCA) Medal for Scientific Achievement (2009), and the IEEE James L. Flanagan Speech and Audio Processing Award (2010). He also received the Achievement Award from the Minister of Science and Technology and the Minister of Education, Japan (1989, 2006), and the Purple Ribbon Medal from the Japanese Emperor (2006). Additional awards and honors include Distinguished Lecturer (IEICE), 1993; Fellow (IEICE), 2001; the Distinguished Achievement Award (IEICE), 2008; Fellow (ISCA), 2008; Medal for Scientific Achievement (ISCA), 2009; NHK Broadcast Cultural Award, 2012; Distinguished Lecturer (ISCA), 2012; Okawa Prize, 2013; Accredited as Person of Cultural Merit by Japanese Government, 2016; Permanent Honorary President of APSIPA, 2020; and ISCA Special Service Medal, 2020.

A Personal Note

On 1st August 2022 members of the ISCA Advisory Council and ISCA Fellows were stunned to receive a message from Keikichi Hirose with the subject “Prof. Furui has passed away”. Although many of his close friends/colleagues knew about Sadaoki’s long battle with cancer, it was nevertheless a huge shock to learn of his passing. Within seconds, a flood of messages circulated in these mailing lists reflecting a profound sense of loss that someone so prominent in our community was no longer with us. Looking over these ~60 messages, it is safe to say that Sadaoki’s friendly smile and dedicated support for junior colleagues and students were cited as often as his technical genius and pioneering role in our community: “a brilliant and lovable man”, “always positive and helpful”, “wonderful technical leader and a warm personal friend”, “a very great mentor”, “a kind and clever person”, “a very generous and helpful colleague”, “a brilliant scientist, prolific community leader, and wonderful human being”, “a tireless contributor to our community and a very nice man”, etc. etc. Clearly, Sadaoki had a profound effect on everyone he met - not just because he was an accomplished scholar, but also because he was such a warm-hearted human being. His passing is not only a great loss to our field, but also a sad loss at a personal level.


Of particular relevance to ISCA is Sadaoki’s role in the integration of INTERSPEECH and the International Conference on Spoken Language Processing (ICSLP). Following the formation of ISCA, it fell to Sadaoki’s presidency to finalize the establishment of an annual conference and the formation of the International Advisory Committee (IAC). Sadaoki’s quiet diplomacy overcame the inevitable obstacles, and paved the way for the growing international organization we enjoy today. Indeed, Sadaoki’s role as ISCA President was a model to those that followed him, and his advice to his successors was precious, making it as easy as possible to step into his shoes.


Despite this sad news we, like so many others, feel privileged to have had the opportunity to know and work with such an influential colleague and valued friend over many formative years in our community. His legacy will not be forgotten. RIP Sadaoki.

2-4ISCA Language SIGS

ISCA supports speech communication research activities in various languages. The individual languages have equal interest, but they may involve have different technical or scientific problems. For example, some languages are tonal, while others are not; Some languages have only one writing system, while others have several. In the ISCA community, we have 6 language Special Interest Groups (SIGs) for Chinese, French, Italian, Iberian, Indian, and Russian. Each SIG is organised by researchers who speak the language of interest as L1 and others who have a technical or scientific interest in the language. Each SIG sponsors domestic and international research activities, and representative members of the SIGs attend a Lang SIG meeting every year during the INTERSPEECH conference. In this meeting, recent activities of each SIG are reported, and new ideas are exchanged. We also review what ISCA can do for the SIGs and what the SIGs can do for ISCA. Each SIG has its own web page, and you can visit the pages here.

Do you want to start a new language SIG? If so, please visit the page above and check what you have to prepare for your SIG. Although it is not yet announced, we’re going to launch a new language SIG in the near future, perhaps for your native language. If so, please support it!.

2-5ISCA Special Interest Group (SIG) 'Spoken Language Translation'


ISCA SIG “Spoken Language Translation”

Aims. The SIG SLT covers all aspects of spoken language translation simultaneous translation and interpretation, speech dubbing, speech-to-text translation, speech-to-speech translation, cross-lingual communication including paralinguistic, emotional or multimodal information, and related areas SIG SLT will (a) provide members of ISCA with a special interest in spoken language translation and its related areas with a means of exchanging news of recent research developments and other matters of interest in spoken language translation; (b) organize challenges and evaluation campaigns; (c) sponsor and organize the International Conference on Spoken Language Translation (IWSLT), meetings, satellites, and tutorial workshops in spoken language translation, operating within the framework of ISCA's by-laws for SIGs; and (d) make available open-source code and data resources, best practices and tools, and evaluation metrics relevant to spoken language translation.


Motivation. Recent interest in speech translation and simultaneous translation by machine has been growing explosively, due to continued performance advances and a growing international need for simultaneous translation and interpretation, speech dubbing, speech-to-text translation, speech-to-speech translation, cross-lingual communication including paralinguistic, emotional or multimodal information, and related areas. The under-covered elements in the current research are, for instance, incremental simultaneous speech-to-speech translation, paralinguistic translation, speaking style translation across languages. The proposed SIG will be organized by the members who are interested in spoken language translation/interpretation from various related areas such as ASR, TTS, and MT.

SIG SLT emerged from over two decades of organizing the International Conference on Spoken Language Translation (IWSLT) and its predecessor C-Star, scaling operations in response to significant growth in the field. The organizers of IWSLT and partners believe it is now time to join with ISCA by creating an ISCA SIG. IWSLT has a 15-year track record of profitability; it runs the premier benchmarking campaign on spoken language translation annually accompanied by an international scientific conference to present and discuss results.
