Features

Features of the voiceless alveolar approximant:

  • 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.
