Is it possible to detect voice while playing back a message? I am using AMD (Answering Machine Detect application) and it seems to work pretty well but some outgoing messages (on my Sprint cell phone for example) have silence in them. After the initial message of about 20 seconds it says "press or say one". Then there is a pause of two or three seconds, followed by "leave a message ofter the tone". That pause breaks AMD. If I could detect voice while playing a message I could stop playing the message, wait for silence and restart playing the message from the beginning. Regards, David Koski
