CVSA Physiological Basis of Voice Stress Analysis 3

Question 1

The fundamental frequency (F0) of a human voice is primarily determined by:

Accepted Answer

The rate at which the vocal cords vibrate

Answer

Fundamental frequency is determined by the vibration rate of the vocal cords, which is controlled by laryngeal muscle tension—the same tension that stress-induced microtremors affect.

Question 2

The sympathetic nervous system's role in CVSA is best described as:

Accepted Answer

Activating the stress response that produces detectable voice changes

Answer

The sympathetic nervous system activates the fight-or-flight stress response, increasing laryngeal muscle tension and producing the physiological voice changes that CVSA instruments detect.

Question 3

In CVSA theory, the term 'psychological set' refers to:

Accepted Answer

The mental and emotional state a subject brings into the examination

Answer

'Psychological set' describes the subject's pre-existing mental and emotional state, which can influence baseline stress levels and must be considered when interpreting CVSA results.

Question 4

How do the vocal folds generate the sound analyzed by CVSA instruments?

Accepted Answer

By vibrating at frequencies determined by air pressure and muscle tension

Answer

Vocal folds generate sound by vibrating due to subglottal air pressure and laryngeal muscle tension; stress-related changes in that tension create the frequency patterns CVSA analyzes.

Question 5

The phenomenon of 'voice tremor' under stress is physiologically caused by:

Accepted Answer

Oscillations in laryngeal muscle tension triggered by the stress response

Answer

Voice tremor under stress results from oscillations in laryngeal muscle tension caused by the autonomic stress response, producing the frequency modulations that CVSA instruments are designed to detect.
