Tap and flap consonants

Source: Wikipedia, the free encyclopedia.
(Redirected from
Tap consonant

In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator (such as the tongue) is thrown against another.

Contrast with stops and trills

The main difference between a tap or flap and a

release
burst. Otherwise a tap/flap is similar to a brief stop.

Taps and flaps also contrast with trills, where the airstream causes the articulator to vibrate. Trills may be realized as a single contact, like a tap or flap, but are variable, whereas a tap/flap is limited to a single contact. When a trill is brief and made with a single contact it is sometimes erroneously described as an (allophonic) tap/flap, but a true tap or flap is an active articulation whereas a trill is a passive articulation. That is, for a tap or flap the tongue makes an active gesture to contact the target place of articulation, whereas with a trill the contact is due to the vibration caused by the airstream rather than any active movement.

Tap vs. flap

Later, however, he used the term flap in all cases.[2] Subsequent work on the labiodental flap has clarified the issue: flaps involve retraction of the active articulator, and a forward-striking movement.[3]

For linguists who do not make the proposed distinction above, alveolars are typically called taps, and other articulations are called flaps.

A few languages have been reported to contrast a tap and a flap (as in the proposed definition cited above) at the same place of articulation. This is the case for Norwegian, in which the alveolar apical tap /ɾ/ and the post-alveolar/retroflex apical flap /ɽ/ have the same place of articulation for some speakers,[4] and

Kamviri, which also has apical alveolar taps and flaps.[5]

IPA symbols

The tap and flap consonants identified by the International Phonetic Alphabet are:

IPA Description Example
Language Orthography IPA Meaning
ɾ
alveolar tap
Spanish pero [peɾo] "but"
ɺ
alveolar lateral flap
Venda vula [vuɺa] "to open"
ɽ
retroflex flap
Warlpiri rdupa [ɽupa] "windbreak"
labiodental flap
Karang vbara [ara] "animal"

The

Kiel Convention
of the IPA recommended that for other taps and flaps, a homorganic consonant, such as a stop or trill, should be used with a breve diacritic:

Tap or flaps: where no independent symbol for a tap is provided, the breve diacritic should be used, e.g. [ʀ̆] or [n̆].[6]

However, the former could be mistaken for a short trill, and is more clearly transcribed ɢ̆, whereas for a nasal tap the unambiguous transcription ɾ̃ is generally used.

Most of the alternative transcriptions in parentheses imply a tap rather than flap articulation, so for example the flap [ⱱ̟] and the tapped stop [b̆] are arguably distinct, as are flapped [ɽ̃] and tapped [ɳ̆].

Retroflex flaps

Most Indic and Dravidian languages have retroflex flaps. In Hindi there are three, a simple retroflex flap as in [bɐɽɑː] big, a murmured retroflex flap as in [koɽʱiː] leper, and a retroflex nasal flap in the Hindicized pronunciation of Sanskrit [mɐɽ̃i] ruby. Some of these may be allophonic.

A retroflex flap is also common in Norwegian dialects and some Swedish dialects.

Lateral taps and flaps

Many of the languages of Africa, Asia, and the Pacific that do not distinguish [r] from l may have a lateral flap. However, it is also possible that many of these languages do not have a lateral–central contrast at all, so that even a consistently neutral articulation may be perceived as sometimes lateral [ɺ] or [l], sometimes central [ɾ]. This has been suggested to be the case for Japanese, for example.[9]

The

[ɻ]. However, the flapped, or tapped, laterals in Iwaidja are distinct from 'lateral flaps' as represented by the corresponding IPA symbols (see below). These phones consist of a flap component followed by a lateral component, whereas In Iwaidja the opposite is the case. For this reason, current IPA transcriptions of these sounds by linguists working on the language consist of an alveolar lateral followed by a superscript alveolar tap and a retroflex lateral followed by a superscript retroflex tap.

A

velar lateral tap may exist as an allophone in a few languages of New Guinea, according to Peter Ladefoged and Ian Maddieson
.

Non-coronal flaps

The only common non-

labiodental flap, found throughout central Africa in languages such as Margi
. In 2005, the IPA adopted a right-hook v,

for this sound. (Supported by some fonts: [ⱱ].) Previously, it had been transcribed with the use of the breve diacritic, [v̆], or other ad hoc symbols.

Other taps or flaps are much less common. They include an

velar lateral tap as an allophone in Kanite and Melpa. These are often transcribed with the breve diacritic, as [w̆, ʟ̆]. Note here that, like a velar trill, a central velar flap or tap is not possible because the tongue and soft palate cannot move together easily enough to produce a sound.[citation needed
]

If other flaps are found, the breve diacritic could be used to represent them, but would more properly be combined with the symbol for the corresponding voiced stop. A palatal or uvular tap or flap, which unlike a velar tap is believed to be articulatorily possible, could be represented this way (by *[ɟ̆, ɢ̆~ʀ̆]).[10]

Though deemed impossible on the IPA chart, a velar tap has been reported to occur allophonically in the Kamviri dialect of the Kamkata-vari language[11] and in Dàgáárè, though at least in the latter case this may in fact be a palatal tap.[12][13]

Tapped fricatives

Voiced and voiceless tapped alveolar fricatives have been reported from a few languages. Flapped fricatives are possible but do not seem to be used.
