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 recognition—based 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.

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.”
