lpc of a voice

[POOJEE]

hello there!

I am new to labview and can any body please help me to calculate the lpc of a sound/voice.

Actually my project is based on voice recognition

For help, you need to give more information.  Start by defining your TLA's  (three letter acronyms).

What does "lpc" mean?

[POOJEE]

Actually I am working in a project ( LabVIEW 8.5 ) that is VOICE recognition and it have following steps

1.Take input of a voice( or take it from an existing file)

2. Calculate its MFCC or LPC

3. Take its HMM or GMM or VQ Modelling and save it to a file.

4. Now take another input of voice and match it from the existing sample of 3-4 voices.

LPc is Linear Predictive Coding (part of Signals Processing )

Thanks Ravens!!!

You need to look at the system identification toolkit. There you will find different methods for calculating your aitoregressive 9all pole) models for LPC. alternatively you can write your own using the autocorrelation function on labView. This is a big project. You can use Active-X and use a commercial speech recognition engine maybe. Older versions of Dragon could be used in labView.

THANKS TOMNZ!

Since I am very new to LabVIEW I dont know anything about it.

If it is do possible to make them seperate VI  or all of them in one VI is possible.

It would be very greatfull if You help further more please.

Thanks!

Everything would be in separate VIs. makes more sense this way since you can test each stage at a time. Haven't seen a HMM vi anywhere.

Thanks TOM!

No I haven't seen them any where.

Tried to find out, but was unlabe to find out HMM of a voice signal.

[tomnz]

Then you'll have to be the first to write one in LabView!

ohhhh!!!! 

thanks!!!!
