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.

11 DEMO Examples that illustrate program function
- CUT = c: Minimum spectral amplitude required for the
estimation of formants (default=16)
- DMIN = d: In cases where the F0-6db-bandwidth cannot be
determined the program looks for a "DMIN"db-bandwidth
(default=4db)
- FRST = e: First spectrum to be used (out of a maximum of 44)
- NSPK = n: Number of spectra to be used for F0 estimation
- PROT = 0: No print output
= 1: Analysis of mean vocal pitch F0 (in Hz)
= 2: Analysis of mean vocal pitch F0 (quartertones)
= 3: Analysis of F0-amplitudes
= 4: Analysis of F0-variability (intonation)
= 5: Analysis of F0-contour
- PLOT = 0: No plot output
= 1: Spectra with markings for formants F0,F1,F2
= 2: F0 distribution (single cases)
= 3: F0-Amplitude distribution (single cases)
= 4: F0 distributions of entire sample (males vs. females)
- PMAX = q: Maximum number of plot pages
= 0: Unlimited number
- PROZ = p: Global maximum for frequency distributions in [%]
= 0: Will be optimized for each individual plot
- LPRT = q: Logical unit number of plot-device (standard=6;
valid numbers are 46-96)
- SAVE = 0: No effect
= 1: Data are to be stored in databank
- DEMO: Spectral analysis of speech recordings
