alveolar approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents the alveolar and postalveolar approximants is ⟨ ɹ ⟩, a lowercase letter r rotated 180 degrees. The equivalent X-SAMPA symbol is ⟨ r\ ⟩. There is no separate symbol for the dental approximant (as in Spanish na) in the International Phonetic Alphabet, which most scholars transcribe with the symbol for da voiced dental fricative, that is ⟨ ð ⟩.
The most common sound represented by the letter
r in English is the postalveolar approximant, pronounced a little more back and transcribed more precisely in IPA as ⟨ ɹ̠ ⟩, though ⟨ ɹ ⟩ is often used for convenience in its place. For further ease of typesetting, English phonemic transcriptions might use the symbol ⟨ r ⟩, even though the former symbol represents the alveolar trill in phonetic transcription.
Features [ edit ]
Features of the alveolar approximant:
manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream. 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 and apical . laminal 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. The
airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
