FDFREQ — Analysis of mean vocal pitch, overtone distributions

Determines the voice sound characteristics, separately for male and female speakers, in terms of mean vocal pitch (fundamental frequency F0, F0-amplitude) and intonation (F0-variability, F0-contour, and overtone distribution). The respective speech parameters are estimated from a sequence of consecutive spectra computed at a quartertone resolution over 7 octaves between 64 Hz and 8192 Hz (cf. program TRANS). The distributions of the above frequency-related speech parameters within a given population can be computed and plotted.

Fig. 23: Voice sound characteristics ("timbre") of a female speaker as quantified through spectral analyses. Spectral intensities are plotted along the y-axis on log-proportional scales and as a function of frequency (x-axis: 7 octaves covering the frequency range of 64-8192Hz). The maxima represent the "overtones" at fixed, physically well-defined intervals from the fundamental frequency F0 ("octave": frequency ratio 2:1; "fifth": frequency ratio 3:2; "forth": frequency ratio 4:3; "major third": frequency ratio 5:4; "minor third": frequency ratio 6:5; etc).
