Artikulaatioelimiä

Artikulaatioelimiä are the organs of speech, collectively known as the vocal apparatus or speech organs. These are the structures in the human body that are essential for producing sounds that form language. The primary artikulaatioelimiä include the lungs, larynx, pharynx, oral cavity, and nasal cavity.

The lungs provide the airflow necessary for speech. This air is exhaled and passes through the larynx, which contains the vocal cords. The vibration of the vocal cords, controlled by muscles, produces the fundamental sound of the voice. The pitch and loudness of this sound can be modified by adjusting the tension and position of the vocal cords.

The pharynx, the part of the throat behind the mouth and nasal cavity, acts as a resonating chamber, amplifying and shaping the sound produced in the larynx. The oral cavity, or mouth, is highly adaptable and contains several key artikulaatioelimiä. These include the tongue, teeth, alveolar ridge (the gum ridge behind the upper teeth), hard palate, soft palate (velum), and lips.

The tongue is a muscular organ that can move in many ways to alter the shape of the oral cavity and to create different speech sounds by touching or approaching other parts of the mouth. The teeth and alveolar ridge are crucial for forming consonants like 't', 'd', and 's'. The lips are used to create sounds such as 'p', 'b', and 'm', and also for vowel articulation. The soft palate can be raised or lowered to control whether air passes through the nasal cavity or the oral cavity, which differentiates nasal sounds (like 'm' and 'n') from oral sounds.

The nasal cavity also acts as a resonator, contributing to the unique quality of nasal sounds. Together, these artikulaatioelimiä work in a coordinated manner to produce the vast range of sounds that make up human speech.
