Question

In the source-filter theory of speech production, _______.

a.) the vibrating vocal folds are the source and the oral/nasal cavities provide the filter.
b.) the oral cavity is the source and the nasal cavity provides the filter.
c.) the respiratory system is the source and the articulatory/resonatory system provides the filter
d.)none

Answer 1

In the source-filter theory, speech production involves the vocal folds as the source of vibration and the oral/nasal cavities act as a filter to shape sounds.

Step-by-step explanation:

In the source-filter theory of speech production, the vibrating vocal folds are the source and the oral/nasal cavities provide the filter. This means that human speech is produced by the vibration of the vocal cords in the larynx while shaping the air column formed by the throat and mouth influences the spectrum of overtones and their intensities. Variations in mouth and tongue position result in different sounds, which form the basis of our speech.
