I've seen your post about your vox recorder. can you give me a hint how
I can check sound in line and find out if it's voice or not? or was
your vox recording based on just level of signal?
is there open source algorithm which I'd be able to use(c,c++ or java)?

Voice as opposed to music is fairly simple. Voice as opposed to data
is trivial. Absolute "this is voice" is impossible.
