ASR : How it works.
Hi
Can some one tell ASR ( Automatic speech recognition ) related sites.
Except : Nuance.com.
I know how to use nuance API in ASR applicatons.
All I need is a pdf/html where I can find some thing that explains how ASR works.

Thank you for educating on google.com.
I did all that, but none of them explains how that is working.

Glad to post again on this board after a long time.
In short ASR is about pattern matching a set of observation vectors over time. The observation vectors being speech frames.
So basically you look at speech waveforms, take them to a suitable frequency domain for analysis and ultimately look at the patterns in frequency and classify them using some kind of engine.
The one I use is HMM. This is state-of-the art ->hence its is being all over, by everyone etc.
For more technical details, visit
www.scirus.com and type ASR there. Tons of journal papers will break it down in BIG detail for you and you will be a happy person.
Now I need someone to help me on how to use the MS Speech SDK 3.0...
