Intelligibility Performance of the LPC-10 and APC/SQ Speech Algorithms in a Fading Environment.

Abstract

The APC/SQ and LPC-10 Speech Algorithms are evaluated for their performance in a fading channel, listener evaluation is performed for recognition of the Phonetic Alphabet. Keywords include: Scintillation; Striations; Speech; LPC-10; APC/SQ; A/D; Speech Intelligibility; Phonetic Alphabet; and VOCODER.
