Default Voice Activated Record


Folks,

I'm brand new to Visual Basic so in this forum, I'm facing a problem at the college, I have this assignment to do, which is a voice activated recorder, and I have no idea where to begin this event code, I'm not sure how does VB works with microphone input, if someone could expend some time to put me in the right way, I would appreciated.

Thanks in advance,

Ivan

Default Microphone sound recording - DirectSound capture

I hate to see threads go unanswered.
"Voice activated" functionality is not easy to achieve in VB6.
There are a number of issues.
Can the sound of the voice be picked up from background noise.
Can a "sound" picked out from background noise be identified as a "voice".
Can anything useful be done to train the computer to recognize voice input as a usable (and discrete) command.
Without third party libraries or controls these things are not a trivial task.
Microsoft does have a Speech Recognition SDK (large, unwieldy and with support for few languages).
The non-DirectX way of recording (inputting) sound is to use the MCI (MS Multimedia) Control, or making direct API calls to winmm.dll.

I know of only one set of code (DirectX4VB tutorial) that shows how record using DirectSound:

The similar "full duplex" version of the code is here.
