how can I allow labview to answer a call from a cellular phone and then allow me to work with the analog data?

[Varnerjared]

I am working on a voice recognition program that will activate certain VIs for me to do data acquistion. In order to do this, i want to use my modem to communicate with labview. Is there a way to have labview answer the modem when i call it with my cell phone and then allow me to have a voice connection?

I have used labview to pick up a call on a cell phone. It is easy as long as you know the protocol used. I'm sure you can do it with landline phone/modem as well.

Yes the best way is to use a external modem that has a serial connection to your computer. When doing this you can use the visa serial functions to sent your "at" commands. You then can detect dtmf tones. Usually the modem manufacturer has a good listing of the commands. The problem comes with the voice connection. To bring in the voice you might have to do some conversions using the sound palette. This is where the problem comes in converting to and from stereo or mono signals. The best way is to exeriment with the functions in the palette with just using a microphone to record a voice. Hope this helps.

I am still really confused Joe, Can you go into more detail with how I can accomplish this? Possibly some VIs?

The receive part I used was a cell phone and not land line one, so I do not have experience with that.

If you want to do it with cell phones, then check out some GSM phones and their developer manuals (Most Nokia and Erricson phones will do just fine). However, if you are going to use cell phones, then check out the SMS (short message system) which you send a text message or email to the receipient which your system can retrieve it and do something. The cost is much cheaper because you can buy SMS devices / services. Search on the internet for SMS technology or just go to www.gsm.org .
