Classifying 'tone' of voice during speech recognition

Started by ypar...@gmail.com April 5, 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.
