Classifying 'tone' of voice during speech recognition - ypar...@gmail.com - Apr 5 7:22:26 2010

Hi,

I am a newbie to speech recognition and DSP field. I am looking for a software
library that will take an audio file and classify the 'tone' of voice in audio
file to one of the few predetermined categories e.g. sad, angry, annoyed, happy,
unknown, 'insufficient data' etc. In case of audio file having multiple tones I
would like to know ranking e.g.

1-Angry (50%)
2-Annoyed (40%)
3-Sad (5%)
4- Unknown (5%)

Can someone direct me to right resources.

Many thanks in advance,
Paresh

This is an area of active research... current methods appear to be
"promising", not reliable.  If you can create such
a library that is content-accurate to 5%, you will be famous.
