Noted that the "History" section seems to have been copied wholesale from another web source. IAlexR ( talk) 04:41, 4 September 2011 (UTC) reply

Please add an explanation of how the device works. It is clear that a microphone can detect simple throat sounds such as "aaah" or "oooh" sounds, but complex, articulate speech is created in the mouth by movement of jaw and tongue, so how are words detected by a microphone in contact with the larynx, quite a distance below the speech-creating mouth? Thank you. — O'Dea ( talk) 21:55, 12 February 2014 (UTC) reply

Those sounds reverberate back down to the throat. I don't have a source to cite, though. WP Ludicer ( talk) 22:02, 9 December 2018 (UTC) reply
