Sibilant

Sibilant

Sibilance is a manner of articulation of fricative and affricate consonants, made by directing a stream of air with the tongue towards the sharp edge of the teeth, which are held close together; a consonant that uses sibilance may be called a sibilant. Examples of sibilants are the consonants at the beginning of the English words sip, zip, ship, chip, and Jeep, and the second consonant in vision. The symbols in the International Phonetic Alphabet used to denote the sibilant sounds in these words are, respectively, . (The sounds, as in chip and Jeep, are affricates; the rest are fricatives.) Sibilants have a characteristically intense sound, which accounts for their non-linguistic use in getting one's attention (e.g. calling someone using "sssst!" or quieting someone using "shhhh!").

In the alveolar hissing sibilants and, the back of the tongue forms a narrow channel (is grooved) to focus the stream of air more intensely, resulting in a high pitch. With the hushing sibilants (occasionally termed shibilants), such as English, and, the tongue is flatter, and the resulting pitch lower.

Sibilants may also be called stridents, a term which refers to the perceptual intensity of the sound of a sibilant consonant, or obstacle fricatives/affricates, which refers to the critical role of the teeth in producing the sound as an obstacle to the airstream. Non-sibilant fricatives and affricates produce their characteristic sound directly with the tongue or lips etc. and the place of contact in the mouth, without secondary involvement of the teeth.

The characteristic intensity of sibilants means that small variations in tongue shape and position are perceivable, with the result that there are a large number of sibilant types that contrast in various languages.
