[asterisk-users] voice detection during playback

[David Koski]

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.
