VOICE RECOGNITION

[stamatios]

Hey guys im final year student and i wanna do voice recognition for my last year project.has anyone done voice recognition to tell me some ysefull thingsand if he has it in lava to sent me in hotstamos@hotmail.comto take a look how its working?

guys thnx

At the risk of feeding a homework troll, there are a lot of ways to skin this cat. There might be someone around here who knows enough to help you straight away, but you're more likely to get better results if you give us more information. For instance...

• What, exactly, are the "useful things" you need your program to do?
  
• Have you looked at any existing voice recognition products and how they might integrate with other software? If not, do that and then come back here and tell us what you found.
  

If you're talking about acquiring data and doing voice recognition from scratch in LabVIEW, I think you've bitten off way more than you can chew. Your best bet would be to find a way to integrate LabVIEW with existing voice technologies, but you need to find those technologies first. People around here will be more than willing to help you with the integration step if you show some initiative up front.

I am an electronic and telecommunications engineering student, and I am working on a project that involves "Voice Recognition". This Voice Recognition project is about a speaker dependent, with isolated words, implementation is done in LabView 8.2, and the port to be used is a Serial or USB. please help with a example. my email is mki.par07@gmail.com thanks

Welcome to LAVA. I can't help you on this one, but I can give you some advice on how this forum tends to work. If you give a problem your best shot, then post what you have done so far, sample code if you have it, and specific questions about what you are stuck on you will usually get replies fast. If you post a generic "please do my homework for me" request, you will not generally get much help.

There is a webcast available at http://www.ni.com/swf/flv/labview/us/vista/vr/ with a quick example of speech recog using the built in Windows Vista capabilities.

Good Luck,

Toby

Do you mean that the audio is to be acquired via the computer's serial or USB port? If so, I think you can rule out the serial interface immediately. As for USB, what hardware do you have or are you thinking of? If the device is accessible as a microphone from the OS, LabVIEW should be able to use it.

LabVIEW has some nice basic functions for capturing and playing back audio via a computer's audio in/out ports that should let you capture your subject's spoken words. Look in Functions-> Programming-> Graphics & Sound-> Sound

If you're more interested in the processing capabilities of LabVIEW, you should probably look at the sound and vibration or the signal processing toolkits.

LabVIEW has been used to build commercial grade audio applications; a company in Boston, MA USA called listeninc.com sells audio systems based on LabVIEW and various signal conditioning hardware.
