Question Sending Modem audio output to Speech Recognition audio input VB / VBA


I have a database application developed around Access with VBA,

I have used the Speech SDK and developed an application that uses MSCOMM to call into a remote IVR system. It sends in the credentials and queries information in response to that IVR's verbal requests. All seems successfull except for one big problem;

I'm using a shared SR engine and its using the system microphone as its audio input, this in turn gets the sound from the speakers which are routed to the telephone line through the modem. Of course this has a number of disadvantages - noise added to the sound from the environment and sound quality degredation as well as speaker volume dependency.

Ideally I would like the SR engine to take its audio input from the modem in paralell with the sound that goes to the speakers (so we can listen in to the call as well).

I can imagin two ways to do that
1. Add an input device to the Audio Mixer for the modem so it can be selected as the default input for the SR
2. find a way to use an InProc SR engine as described in
in reference to the http://msdn.microsoft.com/en-us/libr...68(VS.85).aspx Telephony Speech recognition
(I think that library is missing definitions for the InProc SR especially for Event handling?

I would appreciate any suggestions in this or any code if such is available
Thanks
David

Default

A third possible way, and you are going to have to check the sound card documentaion and modem documenation for voltages but a jumper from speaker to microphone might solve your problems.

Just a thought from left field.

Good Luck
