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
