Did you know that G features an "audio captcha"?
don't spoof the topic rather start a discussion in lounge :D
I dont think you can change any text to audio, unless you have a mechanism or organized logic for it. e.g I am not sure about the background of this request. do you want an audio captcha? for that you can record A - Z and 1 - 9 characters in your voice. Name each file after its character e.g a.avi, 1.avi etc etc
When you generate random captcha string; you can pick the associated audio files for all strings.
