Abstract

A device having an analog storage for storing in real time an electric analogue signal proportional to vocal tract resonance periods within speech pitch periods of speech in gas in deep sea diving. A clock is used for providing clock pulses proportional to the depth at which the speech is being made for clocking the analog signal into the analog storage device. A second clock is used for clocking the speech out of the analog storage device at that frequency corresponding to normal voice.
