Asymmetries in the Cumulative Probability Distributions of the Speech Waveform Instantaneous Amplitude
G. Williams · The Journal of the Acoustical Society of America · 1967
Asymmetries in the cumulative probability distribution of the speech waveform instantaneous amplitudes are studied. It is shown that the asymmetries which occur at large amplitude values are accompanied by a difference in the mean and median values of the distributions. Microphone characteristics and filtering reduce the gross asymmetry of the larynx fundamental waveform, resulting in a reduction in the over-all asymmetry.
