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

dsp.c has silence detection that works quite well for detecting end-of-voice
silence. It is used to allow only a certain amount of silence at the end of
voicemails, for instance. See app_voicemail2.c on how to use it, specifically
the function play_and_record(). Note that the silence threshold (

I don't have any real experience in DSP methodologies, although I have picked up
on the high-level theories in my research. However, I am *very* strong-willed
in the "Where there's a will, there's a way" category. :)
Here's my current thought:

Hi Brad,
If you want to detect that a sound is voice, rather than something else,
it isn't easy. There is information around on the Internet about
methods, but I have never tried them and don't know how well they work.
Unless you have some understanding of DSP I wouldn't bother trying. On
the
Does anyone know if there's public voice detection algorithms available? I've
scoured the net for the last hour or so, and I can't come up with anything
except a few proprietary or embedded solutions.
I know dsp.c uses goertzel algorithms for DTMF detection, but how does one
detect voice?
