Voiceless retroflex trill

Voiceless retroflex trill
ɽ͡r̥
IPA number 125 433 122 402A

The voiceless retroflex trill is a sound that has been reported to occur as an allophone of /ʂ/ in the Maldivian language.[1] Although the tongue starts out in a sub-apical retroflex position, trilling involves the tip of the tongue and causes it to move forward to the alveolar ridge; this means that the retroflex trill gives a preceding vowel retroflex coloration the way other retroflex consonants do, but the vibration itself is not much different from an alveolar trill. Thus, the narrower transcription ɽ͡r̥ is also appropriate.

Features

Features of the voiceless retroflex trill:

  • Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
  • 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.

Occurrence
