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).
