Voiceless dental and alveolar plosives

Voiceless alveolar and dental plosives (or stops) are a type of consonantal sound used in almost all spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar plosives is ⟨t⟩. The voiceless dental plosive can be distinguished with the underbridge diacritic, ⟨t̪⟩ and the postalveolar with a retraction line, ⟨t̠⟩, and the extIPA has a double underline diacritic which can be used to explicitly specify an alveolar pronunciation, ⟨t͇⟩.

The [t] sound is a very common sound cross-linguistically. Most languages have at least a plain [t], and some distinguish more than one variety. Some languages without a [t] are colloquial Samoan (which also lacks an [n]), Abau, and Nǁng of South Africa.^{[citation needed]}

There are only a few languages which distinguish dental and alveolar stops, Kota, Toda, Venda and many Australian Aboriginal languages being a few of them; certain varieties of Hiberno-English also distinguish them (with [t̪] being the local realisation of the Standard English phoneme /θ/, represented by ⟨th⟩).

Features

Here are the features of voiceless alveolar stops:

• Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive.
• There are three specific variants of [t]:
  • Dental, which means it is articulated with either the tip or the blade of the tongue at the upper teeth, termed respectively apical and laminal.
  • Denti-alveolar, which means it is articulated with the blade of the tongue at the alveolar ridge, and the tip of the tongue behind upper teeth.
  • Alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal.
• Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
• It is an oral consonant, which means that air is not allowed to escape through the nose.
• It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.
