The voiced speech of a typical adult male will have a fundamental frequency from 90 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. [3] Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined.
Formant frequencies, in their acoustic definition, can be estimated from the frequency spectrum of the sound, using a spectrogram (in the figure) or a spectrum analyzer. However, to estimate the acoustic resonances of the vocal tract (i.e. the speech definition of formants) from a speech recording, one can use linear predictive coding.

In speech, voiceless phones are associated with vocal folds that are elongated, highly tensed, and placed laterally (abducted) when compared to vocal folds during phonation. [6] Fundamental frequency, the main acoustic cue for the percept pitch, can be varied through a variety of means.
The mismatch between acoustic analyses and what the listener hears is especially noticeable in speech sounds that have a lot of high-frequency energy, such as certain fricatives. To reconcile this mismatch, functional models of the auditory system have been developed. [116]
English phonology is the system of speech sounds used in spoken English. Like many other languages, English has wide variation in pronunciation , both historically and from dialect to dialect . In general, however, the regional dialects of English share a largely similar (but not identical) phonological system.
These capacities include discrimination of frequency, [74] [4] [75] [76] discrimination of the fundamental frequency of harmonic sounds, [75] [4] [76] detection of FM at rates below 5 Hz, [77] melody recognition for sequences of pure tones and complex tones, [74] [4] lateralization and localization of pure tones and complex tones, [78] and ...
