LABIAL •
Voiceless
Trill
  • Trills are sounds which involve a repetitive contact between an active articulator (the tongue tip, the uvula) and a passive articulator (roof of the mouth) and as such they involve a transitional aspect of articulation. The articulation of the alveolar trill is illustrated in the adjacent video.
     

  • Taps consist of a single ballistic movement of the active articulator against the passive articulator.
     

  • Flaps involve a trajectory of the active articulator from one point towards another. During this trajectory the active articulator makes brief contact with he passive articulator.

Hovering the cursor over the phonetic symbols below will show how frequent these sounds are in UPSID (University of California Phonological Segment Inventory Database): this database now contains sound inventories of 451 languages.
