Voice Activated App

[jacque121]

I am having problems locating any code or examples of how to do voice activated recording using either Winmm, MCI or DirectX. I want to take the audio from the microphone and when the proggy senses audio, it starts a wav off recording it. Then when it falls silent, it stops recordings and closes the file.

I know there are programs out there that can do this, like Recall etc which are cool - but to do it in VB would rock.

Many thanks peeps

The speed of the language and the code that you are using counts here. If you are using unoptimized code and a (well, slower than C) language like VB, then you wont get the first second when doing voice activated things. I recommend having you say something like "on" and then when it converts it to text, start recording. But give a sound like Ding-Dong to show when it starts. When you are done, you should wait 4 seconds and then when it gets 4 seconds of near silence then cut off the end four seconds and save it to a wav.

No, sorry, i'm not sure what calls to use or whatever, but I hope that I have helped.

Cheers

Many thanks for that Sastraxi - I totally agree that I may well be looking at the wrong dev env for this task, but it was to support an existing vb6 app you see. I am sure you can do it but how is anyones guess. Have scoured the net but to no avail - shame really.

It cannot be that hard - any takers out there?


thanx again for your help

This code is to long to post(10,000 + charecters), but also my vb is down, so all i can do is attach it. it's from the API-Guide

Great thanx for that - one problem though. You code came thru without CRLF and is one large block. I am having trouble deciphering end of lines as you have (gratefully) placed comments throughout - could you mail me another version direct at jacque121@hotmail.com - if thats not asking too much?

many thanks - very excited to see it
