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".
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 ...
If the consonant is voiced, the voicing is the only sound made during occlusion; if it is voiceless, a stop is completely silent. What we hear as a /p/ or /k/ is the effect that the onset of the occlusion has on the preceding vowel, as well as the release burst and its effect on the following vowel.
(See voice onset time.) Aspiration varies with place of articulation. The Spanish voiceless stops /p t k/ have voice onset times (VOTs) of about 5, 10, and 30 milliseconds, and English aspirated /p t k/ have VOTs of about 60, 70, and 80 ms. Voice onset time in Korean has been measured at 20, 25, and 50 ms for /p t k/ and 90, 95, and 125 for ...
Examples of sinusoidally amplitude- and frequency-modulated signals. The neural representation of stimulus envelope, ENV n, has typically been studied using well-controlled ENV p modulations, that is sinusoidally amplitude-modulated (AM) sounds. Cochlear filtering limits the range of AM rates encoded in individual auditory-nerve fibers. In the ...
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.
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
