COMD 282-001 Speech and Hearing Science - Chapter 6 Part 1

These flashcards cover key concepts from the lecture notes on the articulatory/ resonatory system, focusing on the anatomy and functions relevant to speech production.

What are the three cavities of the vocal tract?

Oral, Nasal, Pharynx.

What is the role of the vocal tract in speech production according to the source-filter theory?

The vocal tract acts as an acoustic resonator that modifies the sound produced by the vocal folds.

What are the functions of the velopharyngeal port in speech?

It is closed for oral sounds and open for nasal sounds.

What distinguishes consonants from vowels?

Consonants are defined by place of constriction, manner of constriction, and voicing, while vowels are characterized by their position in the vowel space or quadrilateral.

What is a muscular hydrostat?

A structure, like the tongue, that has no skeleton or cartilage and provides its own support through muscular action.

What are the intrinsic muscles of the tongue primarily responsible for?

Changing the shape of the tongue and managing fine movements.

What does hypernasality in speech indicate?

It occurs when the velopharyngeal port is open when it should be closed.

List the three divisions of the pharynx.

Nasopharynx, Oropharynx, Laryngopharynx.

What is the significance of the alveolar ridge in speech production?

It serves as a place of constriction for certain consonant sounds.

What changes do the extrinsic muscles of the tongue primarily facilitate?

They are responsible for positioning changes of the tongue.
