A voice change or voice mutation, sometimes referred to as a voice break or voice crack, commonly refers to the deepening of the voice of men as they reach puberty.Before puberty both sexes have roughly similar vocal pitches, but during puberty the male voice typically deepens an octave, while the female voice usually deepens only by a few tones.
The voice may also be heard as breathy, rough, and lacking in power. [2] The onset of puberphonia usually occurs in adolescence, between the ages of 11 and 15 years, at the same time as changes related to puberty are occurring. [2] This disorder usually occurs in the absence of other communication disorders.
Voice changes can also happen. A 2020 study found that evidence suggests voice dysfunction is the earliest sign of motor impairment in PD. The researchers stated that “the complexity and fine ...
Vocal fold phonatory functions are known to change from birth to old age. The most significant changes occur in development between birth and puberty, and in old age. [10] [21] Hirano et al. previously described several structural changes associated with aging, in the vocal fold tissue. [22]
In historical linguistics, a sound change is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound (or, more generally, one phonetic feature value) by a different one (called phonetic change) or a more general change to the speech sounds that exist (phonological change), such as the merger of two sounds or the creation of a new sound.
These registers include modal voice (or normal voice), vocal fry, falsetto, and the whistle register. [1] [2] [3] Registers originate in laryngeal function. They occur because the vocal folds are capable of producing several different vibratory patterns.
Falsetto also describes the momentary, but often repeated, fluctuations in pitch emitted by both sexes while undergoing voice change during adolescence. These changes, however, are more apparent and occur with greater frequency in boys than they do in girls. [26] Failure to undergo proper voice-change is called puberphonia.
Voice break generally refers to transitions between different vocal registers of the human voice. Although singing is mostly done using the modal register, it is important for more professional singers to be able to smoothly move between different vocal registers. Professional singers refer to this break as the Passaggio.
