# Voiced dental and alveolar taps and flaps

The voiced alveolar tap or flap is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents a dental, alveolar, or postalveolar tap or flap is ⟨ɾ⟩.
The terms tap and flap are often used interchangeably. Peter Ladefoged proposed the distinction that a tap strikes its point of contact directly, as a very brief stop, and a flap strikes the point of contact tangentially: "Flaps are most typically made by retracting the tongue tip behind the alveolar ridge and moving it forward so that it strikes the ridge in passing." That distinction between the alveolar tap and flap can be written in the IPA with tap ⟨ɾ⟩ and flap ⟨ɽ⟩, the 'retroflex' symbol being used for the one that starts with the tongue tip curled back behind the alveolar ridge. The distinction is noticeable in the speech of some American English speakers in distinguishing the words "potty" (tap [ɾ]) and "party" (retroflex [ɽ]).
For linguists who do not make the distinction, alveolars and dentals are typically called taps and other articulations flaps. No language contrasts a tap and a flap at the same place of articulation.
The sound is often analyzed and thus interpreted by non-native English-speakers as an 'R-sound' in many foreign languages. In languages for which the segment is present but not phonemic, it is often an allophone of either an alveolar stop ([t], [d], or both) or a rhotic consonant (like the alveolar trill or the alveolar approximant).
If the alveolar flap is the only rhotic consonant in the language, it may be transcribed with ⟨r⟩ although that symbol technically represents the trill.
The voiced alveolar tapped fricative reported from some languages is actually a very brief voiced alveolar non-sibilant fricative.

## Voiced alveolar tap and flap
### Features

Features of the voiced alveolar tap or flap:
* Its manner of articulation is tap or flap, which means it is produced with a single contraction of the muscles so that the tongue makes very brief contact.
* Its place of articulation is dental or alveolar, which means it is articulated behind upper front teeth or at the alveolar ridge. It is most often apical, which means that it is pronounced with the tip of the tongue.
* Its phonation is voiced, which means the vocal cords vibrate during the articulation.
* It is an oral consonant, which means air is allowed to escape through the mouth only.
* It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
* Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.

## Alveolar nasal tap and flap
### Features

Features of the alveolar nasal tap or flap:
* Its manner of articulation is tap or flap, which means it is produced with a single contraction of the muscles so that the tongue makes very brief contact.
* Its place of articulation is 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 voiced, which means the vocal cords vibrate during the articulation.
* It is a nasal consonant, which means air is allowed to escape through the nose, either exclusively (nasal stops) or in addition to through the mouth.
* It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
* Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
