Acoustic Measurement of Vocal Fold Vibration

Question 1

Frequency of VF vibration

Answer 1

most often measured from a waveform or pitch contour; waveforms are not convenient for analyzing pitch over time

Question 2

pitch contours

Answer 2

best display for analyzing fundamental frequency over time.

Question 3

Voice quality

Answer 3

often divided into modal voice, creaky voice and breathy voice

Question 4

creaky voice

Answer 4

VF’s pulse irregularly and often at a very low frequency

Question 5

breathy voice

Answer 5

VF’s never completely close, resulting in airflow even at maximal closure

Question 6

Harmonics to Noise

Answer 6

a measurement of the amount of periodic vs aperiodic energy in a voice-measured from a sustained /a/
