Artikulatsioonisüsteemi

Artikulatsioonisüsteemi, also known as the speech production system or vocal tract, refers to the complex biological structures and processes involved in producing spoken sounds. It encompasses the organs of respiration, phonation, and articulation. The respiratory system, primarily the lungs and diaphragm, provides the airflow necessary for speech. This airflow is then modified by the larynx, which contains the vocal folds responsible for phonation or voice production. The vibrating vocal folds create a sound source that is further shaped by the articulators.

The articulatory organs are the key components of the speech production system. These include the tongue, lips, teeth, alveolar ridge, hard palate, soft palate (velum), and uvula. The tongue is highly mobile and can be positioned in numerous ways to alter the shape of the oral cavity. The lips can be rounded, spread, or brought together to produce various vowel and consonant sounds. Teeth and the alveolar ridge (the bumpy part behind the upper front teeth) play a role in creating fricative and stop consonants. The soft palate can be raised to block airflow through the nasal cavity, producing oral sounds, or lowered to allow air to pass through the nose, resulting in nasal sounds.

Together, these structures work in a coordinated manner to produce the vast range of sounds that constitute human language. The precise movement and interaction of these articulators, influenced by airflow and phonation, are what differentiate one speech sound from another. Understanding the articulatsioonisüsteemi is fundamental to the study of phonetics, speech pathology, and linguistics.
