Alveolar sounds are those made by the front of the tongue (active) touching the alveolar ridge, including both post-alveolar and retroflex sounds.

  • Post-alveolar: sounds that are made with the tongue blade moving making a constriction where the roof of the mouth raises steeply (behind the alveolar ridge).
  • Retroflex: retroflex sounds are similar to post-alveolar in that they are made with a constriction in the same area. Retroflex sounds, however, are made with the tip of the tongue curling back, so that the bottom of the tongue touches the post-alveolar ridge.
