The voiced alveolar tap or flap is a type of
consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for the h sound, which is pronounced without any stricture in the vocal tract. Examples are and pronou ...

Peter Nielsen Ladefoged ( , ; 17 September 1925 – 24 January 2006) was a British linguist and phonetician.
He was Professor of Phonetics at University of California, Los Angeles (UCLA), where he taught from 1962 to 1991. His book '' A Course ...
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 and flap , 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 ) and "party" (retroflex ).
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

In phonetics and phonology, an alveolar stop is a type of consonantal sound, made with the tongue in contact with the alveolar ridge located just behind the teeth (hence alveolar), held tightly enough to block the passage of air (hence a stop cons ...

The voiced alveolar tapped fricative reported from some languages is actually a very brief
voiced alveolar non-sibilant fricative.

manner of articulation
articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators ( speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is ''stricture,'' that is, h ...

In articulatory phonetics, the place of articulation (also point of articulation) of a consonant is an approximate location along the vocal tract where its production occurs. It is a point where a constriction is made between an active and a pa ...
