Vocal intensity and vocal frequency ranks were shorter in the pathological group.
These differing patterns suggest a refinement of vocal frequency rather than modifications of the vocal tract.
The Strouhal number should not be negligible in the high vocal frequency range.
We controlled for vocal frequency variability, pitch accuracy, rhythmicity, syllable duration, phonetic complexity and other relevant factors, such as learning effects or the acoustic setting.
This is primarily based on the assumption that vertebrate scaling of vocal frequency occurs through size-dependent effects on a common vocal apparatus [e.g. [ 80]], thus deviations from scaling relationships might indicate an independent proximate mechanism [ 35].
Formant estimation is based on modeling vocal tract frequency response using linear predictive coding (LPC) techniques.

The Yale Global Tic Severity Scale (YGTSS; Leckman et al. 1989) is a clinician-rated semi-structured inventory (usually used in research) to assess multiple severity dimensions of motor and vocal tics (frequency, intensity, complexity, strength, and interference) as well as tic-related impairment.
The masking potential of group locomotion therefore should be significant, especially for environmental sounds or vocal calls of frequencies similar to ISOL.
These include the use of a sound spectrograph a device that depicts graphically such vocal variables as frequency, duration, and intensity to produce voicegraphs, or voiceprints, and the use of a technique known as DNA fingerprinting, an analysis of those regions of DNA that vary among individuals, to identify physical evidence (blood, semen, hair, etc).
