Reduction of Peak/RMS Ratio of Speech by Amplitude Compression and Quadratic Phase Dispersion
Quadratic phase dispersion was combined with amplitude compression to reduce the peak/ rms ratio of speech from 15.8 dB to 8.1 dB, which is 0.6 dB more reduction than that for amplitude compression alone and 0.9 dB more reduction than a commercial processor. The testing used six phoneme-specific sentences, each spoken by ten talkers. Additional preliminary work suggests that further enhancement would result from adaptive processing.
