What Is a Nasal Voice?
The nasal cavity resonates when it sounds. Nasal sound is a part of speech formation, and the level of nasal sound is directly related to the quality of speech. Phonetic consonants m, n, and ng must be sent through the nasal cavity. During the articulation, the oral airflow path is blocked, the soft palate is drooping, and the sound of nasal ventilation is emitted. A type of consonant classified by nasal sounds. When speaking, the airflow path in the mouth is blocked, the soft jaw sags, and the airflow passes through the nasal cavity. Ordinary nasal sounds can also be considered as a type of stop sound, because the airflow path is blocked during pronunciation. Some pronunciation methods are confused with nasal sounds, such as semi-vowels. When various nasal or soft palate diseases occur, normal nasal sounds change.
