You didn't mention how you might record the sound bites. As a suggestion, check out Festival/MBROLA. I use it to convert my weather data to a .WAV and .MP3 file, so that it may be played out over an Amateur Radio transciever on request.

If you'd like to hear the current weather, click here for a .WAV file (about 580K), or here for a .MP3 file (about 170K). And finally, here is a link to a page that will let you type in your own phrases and return them as a .WAV file.

And this is a link the Festival/MBROLA software.
