Abstract:

Bandwidth compression of speech signals is done by aliasing the fricative-sound signals 4-8 KHz into the voiced-sound signal band for transmission 0-4 KHz. To minimize distortion, aliasing foldover is done only when the fricative band power is more than twice the voice band power. Patents
