puheenliikkeen

Puheenliikkeen is a Finnish term that translates to "speech movement" or "movement of speech." It refers to the physical actions of the mouth, tongue, jaw, and vocal cords that are necessary for producing spoken language. These movements are highly coordinated and rapid, allowing for the articulation of a wide range of sounds.

The process of puheenliikkeen involves several stages. First, air is expelled from the lungs and passes through the larynx, where it vibrates the vocal cords to create sound. This sound is then modified by the articulators in the oral cavity. The tongue can move to different positions to shape vowels and consonants, the lips can be rounded or spread, and the jaw can be opened or closed. The velum, or soft palate, can be raised or lowered to control whether air passes through the nose or mouth.

Difficulties with puheenliikkeen can lead to speech disorders. These can include articulation disorders, where individuals have trouble producing specific sounds, or apraxia of speech, a motor programming disorder that affects the ability to plan and sequence the movements of speech. The study of puheenliikkeen is important in fields such as linguistics, phonetics, speech-language pathology, and neuroscience, as it provides insights into the complex mechanisms of human communication. Understanding these movements helps in diagnosing and treating speech impairments and in developing technologies that mimic human speech.
