Multiparametric Analysis of Speaking Fundamental Frequency in Genetically Related Speakers Using Different Speech Materials

The present data derives from a Ph.D. research on the inter-speaker discriminatory potential of Fundamental Frequency descriptors in comparisons involving genetically-related and non-genetically related speakers.A set of 15 f0 measures were considered for assessment in connected speech (i.e., at the domain of sentences), including descriptors of f0 dispersion, central tendency, and modulation f0M, as presented below. As for lengthened vowels, given the more stationary f0 patterns observed, only the first seven parameters were considered for the analysis:f0mean: f0 mean in semitones ref 1 Hz/ and in Hertz f0med: f0 median in semitones ref 1 Hz/ and in Hertzf0min: f0 minimum in semitones ref 1 Hz/ and in Hertzf0max: f0 maximum in semitones ref 1 Hz/ and in Hertzf0sd: f0 standard-deviation in semitones ref 1 Hz/ and in Hertzf0base: Base value of f0 in semitones ref 1 Hz/ and in Hertz (i.e., equivalent to the 7.4th quantile of the f0 sample)f0SAQ: f0 semi-amplitude between quartiles in semitones ref 1 Hz/ and in Hertz (i.e., a non-parametric measure of f0 dispersion)f0M1: Smoothed f0 peak rate in peaks per second (i.e., f0 peak rate/s)f0M2: Standard-deviation of f0 maxima in semitones ref 1 Hz/ and in Hertz (i.e., when there is more than one peak in the interval)f0M3: Standard-deviation of the F0 maxima positions in seconds (i.e., standard-deviation of peaks' duration)f0M4: 1st-derivative f0 mean in Hertz/frame of the positive derivatives (i.e., f0 rising rate in the peaks)f0M5: 1st-derivative f0 mean in Hertz/frame of the negative derivatives (i.e., f0 falling rate in the peaks)f0M6: 1st-derivative f0 standard-deviation in Hertz/frame of the positive derivatives (i.e., standard deviation of f0 rising rate)f0M7: 1st-derivative f0 standard-deviation in Hertz/frame of the negative derivatives (i.e., standard deviation of f0 falling rate)f0M8: Mean peakness of f0 max in semitones relatively to f0 range multiplied by 1000 (i.e., corresponding to the width of f0 peaks)AN IMPORTANT NOTE:Subsetting is required for "Lengthened Vowels", so vowel duration (DUR) is ≥ 160 ms.
