COST 277- Nonlinear Speech Processing

The main objective of this Action is to improve the quality and capabilities of the voice services for telecommunication systems through the development of new nonlinear speech processing techniques. The proposed new mathematical methods are expected to provide advances in generic speech processing functions. Examples of these are: higher quality speech synthesis, more efficient speech coding, improved speech recognition, and improved speaker identification. It is envisaged that the proposed nonlinear processing techniques will significantly facilitate the acceptance of voice interfaces for information systems such as the mobile Internet (by improving synthesis and recognition). Additionally, these techniques are expected to make significant contributions to the improvement of future generations of speech coders in wireless networks (including packet-based wireless networks).

If you want to know what they look like then some of them are seen enjoying themselves in Denmark!
Alternatively you could see us all, (except that Gernot Kubin is hiding me with his head!), being very merry in Vietri-sul-Mare,
or taking a break from the technical sessions in Vietri, (I am 4th from the left!), here.
