Quadratic phase dispersion was combined with amplitude compression to reduce the peak/rms ratio of speech from 15.8 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 10 talkers. Additional preliminary work suggests that further enhancement would result from adaptive processing.
