Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as unvoiced) or voiced. The term, however, is used to refer to two separate concepts:
Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds. It is an oral consonant, which means air is allowed to escape through the mouth only.
This anomalous feature of voiceless speech sounds is better understood if it is realized that it is the change in the spectral qualities of the voice as abduction proceeds that is the primary acoustic attribute that the listener attends to when identifying a voiceless speech sound, and not simply the presence or absence of voice (periodic energy).
The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive (from the glottis), and pulmonic ingressive (from the lungs). The opposite of an ingressive sound is an egressive sound, by which the air stream is created by pushing air out through the mouth or nose. The ...
The voiceless bilabial fricative, voiced bilabial fricative, and the bilabial approximant do not exist as the primary realizations of any sounds in English, but they occur in many languages. For example, the Spanish consonant written b or v is pronounced, between vowels, as a voiced bilabial approximant.
Among widespread speech sounds in the world's languages, the upper pharynx produces a voiceless fricative and a voiced sound that ranges from fricative to (more commonly) approximant, . The epiglottal region produces the plosive as well as sounds that range from fricative to trill, and . Because the latter are most often trilled and rarely ...
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds or, in the case of sign languages, the equivalent aspects of sign. [1] Linguists who specialize in studying the physical properties of speech are phoneticians.
In 2010, it was discovered that whispering is one of the many triggers of ASMR, [6] a tingling sensation caused by listening to soft, relaxing sounds. This phenomenon made news headlines after videos on YouTube of people speaking up close to the camera in a soft whisper, giving the viewer tingles. [ 7 ]
