Voiceless dental fricative

From Academic Kids

Template:Infobox IPA The voiceless dental fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is , and the equivalent X-SAMPA symbol is T. The dental fricatives are often called "interdental" because they are often produced with the tongue between the upper and lower teeth, and not just against the back of the teeth, as they are with other dental consonants. The IPA symbol is the Greek letter theta, which is used for this sound in Greek, and the sound is thus often referred to as "theta".

Features of the voiceless dental fricative:

In English

The voiceless dental fricative occurs in English, and it is the sound denoted by the 'th' digraph in thing and bath. It is different from the sound represented by 'th' in this and the, which is the voiced dental fricative.

In Old English, the letters and were used interchangeably for this sound and the voiced dental fricative, but they have been dropped from modern usage in favour of the 'th' digraph. Although the same digraph is used for the voiced and voiceless forms, these sounds are not interchangeable in spoken English.
