THE CORRECTION OF HELIUM SPEECH DISTORTION.
Abstract
A technique for removing the distortion inherent in speech uttered in a helium-rich atmosphere is the object of considerable research. The report describes an approach which corrects the formant frequencies and the vowel-consonant ratios, two factors which are the most affected by the helium environment. The correction process occurs in real time, the signal suffering less than 10 milliseconds delay. Because the circuitry is largely digital, processor volume is estimated to be about 10 cubic inches after the first step toward microminiaturization is taken. (Author)
