I've made part of an Euphoria application which uses a modem to dial telephone numbers; the computer's speakers output the dial tone, dialing touch tones, and the voice of the person who then answers.

What I'd like to do now is allow a microphone connected to the computer to serve as the voice input for the person who originated the call via the computer.

Does anyone know a way I could do that?

I did try a microphone, hopeing that it might automagically work, but it didn't.

(I know I could just have them pick up a phone after the connection is made, but I wanted to make it easier than that. And, curiously, there's a very perceptible TIME LAG from when the answering person speaks until that speech comes out the computer's speakers.)

Dan:

I think that you should be able to do that by using WIN32 MCI programming.

If you goto this site there is information about using the MCI mixer and etc. http://home.roadrunner.com/jgglatt/tech/winapi.htm

I don't think it matters how the mike is connected because windows just sees it as a device.

Using Win32 API you can get a list of the connected devices.

Good Luck

Thanks for responding, BRyan!

You're right that the USB mic should be recognized and accessible relatively easily, the problem as I see it is outputting the mic to the TELEPHONE LINE. The MODEM dials, connects to, and outputs data to, and inputs data and SOUND (voice) from, the telephone line; but I'm not sure if it's even POSSIBLE to send the output of the SOUND CARD (which is what I presume the mic input goes thru) onto the tele line, or through the modem to the tele line.

I know there's some data/VOICE external modems, which I think relates, but I've read that laptop's modems are NOT (usually?) "VOICE" modems, which may mess me up.

But thanks again for responding!
