S. Voran, "Listener Ratings of Speech Passbands," Proceedings of the 1997 IEEE Workshop on Speech
Coding for Telecommunications, Pocono Manor, September 1997.
Abstract:
We describe a listening experiment that measures the perceived speech quality of 19 speech passbands using
8 talkers and 28 listeners. Results are referenced to the traditional wide-band and narrow-band
telephony passbands. Our findings may help those who wish to select new speech coding passbands that maximize
perceived speech quality under bit-rate constraints. We identify several passbands that show particular promise.
