Place of articulation

Place of Articulation

Place of articulation (IPA: /pleɪs ɒv ɑːrtɪkjʊˈleɪʃən/) refers to the point in the vocal tract where the airflow is constricted or blocked, resulting in the production of different speech sounds. The term originates from the Latin words 'locus' meaning place and 'articulatio' meaning joint or connection.

Description

In Phonetics, the place of articulation is one of the three parameters for classifying consonant sounds, the other two being manner of articulation and voicing. The place of articulation is determined by the active articulator, usually some part of the tongue, and the passive articulator, usually some part of the upper vocal tract.

There are several types of places of articulation, each producing distinct sounds. These include:

• Bilabial: The active articulator is the lower lip, and the passive articulator is the upper lip.
• Labiodental: The active articulator is the lower lip, and the passive articulator is the upper teeth.
• Dental: The active articulator is the tip of the tongue, and the passive articulator is the upper teeth.
• Alveolar: The active articulator is the tip of the tongue, and the passive articulator is the alveolar ridge.
• Post-alveolar: The active articulator is the tip or blade of the tongue, and the passive articulator is the back of the alveolar ridge.
• Palatal: The active articulator is the front of the tongue, and the passive articulator is the hard palate.
• Velar: The active articulator is the back of the tongue, and the passive articulator is the soft part of the roof of the mouth known as the velum.
• Uvular: The active articulator is the back of the tongue, and the passive articulator is the uvula.
