Features

Features of the alveolar approximant:

  • Its manner of articulation is approximant, which means it is produced by bringing one articulator close to another but without the vocal tract being narrowed to such an extent that a turbulent airstream is produced.
  • Its place of articulation is alveolar, which means it is articulated with either the tip or the blade of the tongue against the alveolar ridge, termed respectively apical and laminal.
  • Its phonation type is voiced, which means the vocal cords are vibrating during the articulation.
  • It is an oral consonant, which means air is allowed to escape through the mouth.
  • It is a central consonant, which means it is produced by allowing the airstream to flow over the middle of the tongue, rather than the sides.
  • The airstream mechanism is pulmonic egressive, which means it is articulated by pushing air out of the lungs and through the vocal tract, rather than from the glottis or the mouth.

In speech there are different ways of producing a consonant. ... Approximants are speech sounds that could be regarded as intermediate between vowels and typical consonants. ... In speech, consonants may have different places of articulation, generally with full or partial stoppage of the airstream. ... Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the superior teeth. ... The alveolar ridge is the ridge on the roof of the mouth between the teeth and the hard palate. ... An apical consonant is a phone produced by obstructing the air passage with the very tip (end) of the tongue. ... A laminal consonant is a phone produced by obstructing the air passage with the flattened end of the tongue. ... Phoneticians define phonation as use of the laryngeal system to generate an audible source of acoustic energy, i. ... An oral consonant is a consonant sound in speech that is made by allowing air to escape from the mouth. ... A central or medial consonant is a consonant sound that is produced when air flows across the center of the mouth over the tongue. ... In phonetics, initiation is the action by which an air-flow is created through the vocal tract. ... This page is a candidate to be moved to Wiktionary. ... The heart with relation to the lungs (from an older edition of Grays Anatomy) This x-ray of the human chest shows the lungs as dark regions The lung is an organ belonging to the respiratory system and interfacing to the circulatory system of air-breathing vertebrates. ...

In English

Most English dialects use this sound for the letter r and the digraph wr. Originally the second sound was labialized, but the distinction has been lost from most dialects, and now both r and wr are labialized at the start of a syllable, as in red /ɹʷɛd/. The English language is a West Germanic language that originates in England. ... Labialisation is a secondary articulatory feature of phonemes in a language, most usually used to refer to consonants. ...
