INSTANT REPLAY HELIUM SPEECH UNSCRAMBLER USING SLOWED TAPE FOR CORRECTION

摘要

The helium speech processing device employs a cassette tape recording system which makes a sentence-by-sentence or phrase-by-phrase recording of the speech of a helium gas breathing diver and replays this recording at a reduced speed to provide increased intelligibility. The speed of replay is controllable by the diver and automatically in response to a depth sensing mechanism as well as a speed range control mechanism which is pre-set in dependence upon a particular gas mixture that the user is breathing.
