| Total award
amount |
In study |
| Start/end dates |
24 months starting
June 1st 2003. |
| Description |
In
this project four topics will be addressed:
a) speech technology;
b) conversational interfaces with Galaxy
II architecture;
c) implementation of speech technology DSP;
and,
d) usability evaluation of dialogue systems.
Several prototypes will be developed along
the project, which allow to follow the progress
in the research, and to discuss with companies
possible applications and technology transfer
issues.
