The concept of voice onset time can be traced back as far as the 19th century, when Adjarian (1899: 119) [1] studied the Armenian stops, and characterized them by "the relation that exists between two moments: the one when the consonant bursts when the air is released out of the mouth, or explosion, and the one when the larynx starts vibrating".
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: Voicing can refer to the articulatory process in which the vocal folds vibrate, its primary use in phonetics to describe phones , which are particular speech sounds.
The /t/ voiceless stop follows the /s/ (fricative) here. Voiced obstruents, which include stops and fricatives, such as /b, d, ɡ, v, ð, z, ʒ/, that come at the end of an utterance like /v/ in "improve" or before a voiceless sound like /d/ in "add two") are only briefly voiced during the articulation.
In an artificial continuum between a voiceless and a voiced bilabial plosive, each new step differs from the preceding one in the amount of VOT. The first sound is a pre-voiced [b], i.e. it has a negative VOT. Then, increasing the VOT, it reaches zero, i.e. the plosive is a plain unaspirated voiceless [p].
The alveolar and dental ejective stops are types of consonantal sounds, usually described as voiceless, that are pronounced with a glottalic egressive airstream. In the International Phonetic Alphabet, ejectives are indicated with a "modifier letter apostrophe" ʼ , [1] as in this article.
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.

A similar historical sound change also occurred in Veinakh and Lezgic in the Caucasus, and it has been postulated by the glottalic theory for Indo-European. [2] Some Khoisan languages have voiced ejective stops and voiced ejective clicks; however, they actually contain mixed voicing, and the ejective release is voiceless.
