Sound and speech processing
Project Leaders :

and Jean-Marc Boucher
Aims and objectives throughout the project
The theme of the project "Sound and speech processing" is the application of
signal processing to audio and speech reproduction
Department:

- Improvement of the acoustic quality of high-end coaxial speakers (working
in conjunction with the company, Cabasse);
- Introduction of acoustic criteria for speech synthesis (in collaboration with
France Telecom R&D);
- Automatic segmentation of natural spontaneous speech;
- Speech synthesis by deconvolution (in collaboration with France Telecom
R&D);
- Speech signal processing to improve audio intelligibility and speech
recognition performance in challenging environments. This topic came out
of a project in conjunction with the University of Rabat and is included
partially in the Franco-Tunisian CMCU 1 project "Image, Wavelets and
Fractals", which includes a focus on speech processing.
The technical and scientific challenges are the following:
• Reverberation deconvolution in auditoriums and other large rooms;
• Individualization of voice synthesis parameters;
• Accounting for acoustic criteria for speech synthesis and recognition;
• Automatic segmentation of large voice synthesis corpora in order to
improve the acceptability of synthetic speech in consumer applications;
• Perceptual speech denoising and automatic noise spectra estimation in
the presence of speech
