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".
If one analyzes the sound spectrogram of [ba] and [pa], for example, [p] and [b] can be visualized as lying somewhere on an acoustic continuum based on their VOT (voice onset time). It is possible to construct a continuum of some intermediate tokens lying between the [p] and [b] endpoints by gradually decreasing the voice onset time.
For example, one of the most studied cues in speech is voice onset time or VOT. VOT is a primary cue signaling the difference between voiced and voiceless plosives, such as "b" and "p". Other cues differentiate sounds that are produced at different places of articulation or manners of articulation. The speech system must also combine these cues ...
Using a speech synthesizer, speech sounds can be varied in place of articulation along a continuum from /bɑ/ to /dɑ/ to /ɡɑ/, or in voice onset time on a continuum from /dɑ/ to /tɑ/ (for example). When listeners are asked to discriminate between two different sounds, they perceive sounds as belonging to discrete categories, even though ...
For example, if English-learning infants are exposed to a prevoiced /d/ to voiceless unaspirated /t/ continuum (similar to the /d/ - /t/ distinction in Spanish) with the majority of the tokens occurring near the endpoints of the continuum, i.e., showing extreme prevoicing versus long voice onset times (bimodal distribution) they are better at ...
People are more likely to be able to hear differences in sounds across categorical boundaries than within them. A good example of this is voice onset time (VOT), one aspect of the phonetic production of consonant sounds. For example, Hebrew speakers, who distinguish voiced /b/ from voiceless /p/, will more easily detect a change in VOT from -10 ...

The voice onset time (VOT) helps to measure the second language speaker’s proficiency by analysing the participants’ ability to detect distinctions between similar-sounding phonemes. [6] VOT refers to "the time interval between the onset of the release burst of a stop consonant and the onset of periodicity from vocal fold vibration" [5] (p
