I am trying to detect if a caller is an automated greeting voice. And if so, take an action.

I have samples of the caller recording that I am looking to match. So this is like a really complex tone detection I guess.

It would work like this.

- Call comes in

- We answer/bridge the call

- We start to listen for about 10 seconds.

- During this time we are trying to match a snippet of a sound sample (say 2 or 3 seconds worth) we have recorded on a file on the server. We are trying to match this sound sample to the caller side only.

- If we hear a match, we take the action. Or if we don’t hear the match, we might take a different action.

Any of this sound doable? Any guidance on how to accomplish this?
