Speech Processing
Speech Coding at Very Low Bit Rate VLBR (< 600 bits/s).
These bit rates have to be commpared to those used in mobile cellular systems that are typically equal to 8000 bits/s.
This theme was initialized with the PHD work of Jan Cernocky in collaboration between ESIEE, Telecom-Paris (G. Chollet) and the Technical University of Brno (Czech Republic).
It as been going on in the the frame of:
- a RNRT project (SYMPATEX) with Telecom-Paris, Thalès Communications, and Elan Speech
- and in the frame of Marc Padellini's PHD with Thalès-Communications, co-supervised with François Capman.
The developed VLBR speech coding technique is realized by indexation of automatically derived acoustical units. It is based on a speech recognition approach combined with a speech synthesis using a large speech corpus stored in memory.
