− Voiced Voice (phonetics) Voice or voicing is a term used in phonetics and phonology to characterize speech sounds, with sounds described as either voiceless or voiced. The term, however, is used to refer to two separate concepts. Voicing can refer to the articulatory process in which the vocal cords vibrate...

Preaspiration

In phonetics, preaspiration is a period of voicelessness or aspiration preceding the closure of a voiceless obstruent, basically equivalent to an -like sound preceding the obstruent. In other words, when an obstruent is preaspirated, the glottis is opened for some time before the obstruent closure...

Obstruent

An obstruent is a consonant sound formed by obstructing airflow, causing increased air pressure in the vocal tract, such as [k], [d͡ʒ] and [f]. In phonetics, articulation may be divided into two large classes: obstruents and sonorants....

s. To feel or see the difference between aspirated and unaspirated sounds, one can put a hand or a lit candle in front of one's mouth, and say pin ([pʰɪn]) and then bin ([bɪn]). One should either feel a puff of air or see a flicker of the candle flame with pin that one does not get with bin. In most dialects of English, the initial consonant is aspirated in pin and unaspirated in bin.

s are aspirated for most native speakers when they are word-initial or begin a stressed syllable, as in pen, ten, Ken. They are unaspirated for almost all speakers when immediately following word-initial s, as in spun, stun, skunk. After s elsewhere in a word they are normally unaspirated as well, except when the cluster is heteromorphemic and the stop belongs to an unbound morpheme; compare dis[t]end vs. dis[tʰ]aste. Word-final voiceless stops optionally aspirate.

are examples of languages that do not have aspirated consonants.

There are degrees of aspiration. Armenian and Cantonese have aspiration that lasts about as long as English aspirated stops, as well as unaspirated stops like Spanish. Korean has lightly aspirated stops that fall between the Armenian and Cantonese unaspirated and aspirated stops, as well as strongly aspirated stops whose aspiration lasts longer than that of Armenian or Cantonese. (See voice onset time

Voice onset time

.) An old IPA symbol for light aspiration was [ ʻ ] (that is, like a rotated ejective symbol), but this is no longer commonly used. There is no specific symbol for strong aspiration, but [ʰ] can be iconically doubled for, say, Korean *[kʻ ] vs. *[kʰʰ]. Note however that Korean is nearly universally transcribed as [k] vs. [kʰ], with the details of voice onset time given numerically.

Aspiration also varies with place of articulation

Place of articulation

In articulatory phonetics, the place of articulation of a consonant is the point of contact where an obstruction occurs in the vocal tract between an articulatory gesture, an active articulator , and a passive location...

. Spanish /p t k/, for example, have voice onset times (VOTs) of about 5, 10, and 30 milliseconds, whereas English /p t k/ have VOTs of about 60, 70, and 80 ms. Korean has been measured at 20, 25, and 50 ms for /p t k/ and 90, 95, and 125 for /pʰ tʰ kʰ/.

Although most aspirated obstruents in the world's language are aspirated stops or aspirated affricates, aspirated fricatives such as [sʰ] have also been documented in some languages.

Vowel

In phonetics, a vowel is a sound in spoken language, such as English ah! or oh! , pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis.
