Postdoc proposal Lexicon Free Spontaneous Speech Recognition using Sequence-to-Sequence Models. December 20, 2019 1 Postdoc Subject The goal of the project is to advance the state-of-the-art in spontaneous auto- matic speech recognition (ASR). Recent advances in ASR show excellent per- formances on tasks such as read speech ASR (Librispeech), TV shows (MGB challenge), but what about spontaneous communicative speech ? This postdoc project would leverage existing transcribed corpora (more than 300 hours) recorded in everyday communication (speech recordings inside a family, in a shop, during an interview, etc.). We will investigate lexicon free methods based on sequence-to-sequence ar- chitectures and analyze the representations learnt by the models. Research topics: End-to-end ASR models Spontaneous speech ASR Data augmentation for spontaneous language modelling Use of contextualized language models (such as BERT) for ASR re-scoring Analyzing representations learnt by ASR systems 2 Requirements We are looking for an outstanding and highly motivated postdoc candidate to work on this subject. Following requirements are mandatory: PhD degree in natural language processing or speech processing. Excellent programming skills (mostly in Python and deep learning frame- works). 1 Interest in speech technology and speech science Good oral and written communication in English (French is a plus while not mandatory) Ability to work autonomously and in collaboration with other team mem- bers and other disciplines 3 Work context Grenoble Alpes Univ. o puting facilities, as well as remarkable surroundings to explore over the week- ends. The postdoc project will be funded by the Grenoble Articial Intelligence Institute (MIAI). The candidate will work both at LIG-lab (GETALP team) and LIDILEM-lab. The duration of the postdoc is 18 months. 4 How to apply? Applications should include a detailed CV; a copy of the last diploma; at least two references (people likely to be contacted); a cover letter of one page; a one-page summary of the PhD thesis. Applications should be sent to lau- rent.besacier@imag.fr, solange.rossato@imag.fr and aurelie.nardy@univ-grenoble- alpes.fr. Applications will be evaluated as they are received: the position is open until it is lled. |
