I've had thoughts about this, but I think it would be much simpler/work better to do it with hardware... ie: Put a highly directional microphone (mic1) in front of your mouth, and second omnidirectional mircophone (mic2) on your shoulder/back/chest/topofhead... Then use an op-amp wired in a subtractive sort of way to remove the waveform of mic2 from that of mic1, if you get my drift. Unfortunately I don't have the parts/money to put together a wearable that's fast enough for speech recognition, so I haven't tried this idea yet. -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.ml.org
