Would it be possible to make a sub-vocal recording device?

Asked by HungryGuy (16044points) September 11th, 2010

Would it be possible to make a recording device with a tiny microphone pressed against a person’s throat or jawbone, pick up everything that a person whispers or sub-vocalizes, and converts that sub-vocal speech to text, and save that text to a text file on a thumb drive? Just wondering, is all…

Yes. To reduce development time I’d start with as much COTS (commercial off the shelf) parts as possible. The only new bit would be a sensitive preamp to get the levels up to where commercial software can read it. Try a National Semiconductor LM324 quad op amp. The output would then go into your normal mic input. Use Dragon Naturally speaking software and have it learn the new sound patterns by reading the learning text in the voice you want to record.

Sounds like a plan… Thanks!
