TRANS — Tonal spectral analysis covering 7 octaves

Determines the frequency characteristics of a speech recording through spectral analysis. Spectral analysis results in a set of 168 spectral parameters that cover 7 octaves between 64 Hz and 8192 Hz at a quartertone resolution (24 equidistant tones per octave). Spectra may be stored in the databank and subsequently used for investigations into the voice sound characteristics of male and female speakers (cf. program FDFREQ) or used for the construction of spectral patterns (cf. program PATTERNS, computerized identification of persons by spectral voice patterns).

voxFig22
Fig. 22: Voice sound characteristics ("timbre") of a male 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 shaded area denotes the variability around mean spectral intensities ("characteristic variability"). It is this frequency-dependend variability that makes voices easily distinguishable from each other. The maxima represent "overtones" at fixed, physically well-defined intervals over the fundamental frequency F0 (please compare with the spectrum of the female speaker in Fig. 24).
