Speech & Audio Processing

Speech processing has been one of the mainstays of Idiap’s research portfolio for many years. Today it is still the largest group within the institute, and Idiap continues to be recognised as a leading proponent in the field.

The expertise of the group encompasses statistical automatic speech recognitionbased on hidden Markov models, or hybrid systems exploiting connectionist approaches, text-to-speech, and generic audio processing, covering sound source localization, microphone arrays, speaker diarization, audio indexing, very low bit-rate speech coding, and perceptual background noise analysis for telecommunication systems.

Over 12 millions Swiss francs for more inclusive ICT
tech — Nov 03, 2021

Access to information is a challenge for disabled people, even at a time when communications channels are increasing. An international consortium gathering researchers, as well as private and public partners, under the leadership of the University of Zurich and including Idiap and Icare from the French speaking side of Switzerland was granted 6 million Swiss francs from Innosuisse—completed by 6 million from private partners—to take up this challenge.

Revisiting autoencoders for speech representation learning
research — last modified Jul 16, 2021

“The deep artificial neural networks are inspired from the hierarchical structure of the human brain. Therefore, questioning the neural networks to learn robust, generalizable representations (abstractions) just like the human brain is not absurd, but challenging. However, revisiting fundamentals can be helpful.”
