What does nasality refer to in speech?

• A. The quality of sound produced without airflow through the nasal cavity
• B. The quality of sound from airflow passing through the nasal cavity
• C. The level of sound intensity in speech production
• D. The uniqueness of speech sounds based on pitch variation

Answer: (B)

Nasality in speech refers to the quality of sound that arises when airflow passes through the nasal cavity. This characteristic is especially prominent in certain speech sounds, like nasal consonants (e.g., /m/, /n/, and /ŋ/), where the velum is lowered, allowing air to escape through the nose in addition to the mouth. This airflow through the nasal cavity modifies the sound waves produced in the vocal tract, giving nasally pronounced sounds their distinctive quality.

In contrast to nasality, sounds produced without any airflow through the nasal cavity result in what are termed oral sounds. These sounds do not benefit from the resonance and quality imparted by the nasal passages.
