Acoustic analysis of voice Flashcards
The number of times the amplitude of the sound wave is captured per second is referred to as….
sampling rate
In typical voices the _________ generally appears as the lowest harmonic frequency in the voice signal and may be observed in the spectrum of the voice signal as the frequency spacing between the harmonics.
Fundamental frequency
A measure that may be used to describe the average fundamental frequency variability is the….
Fundamental frequency deviation OR fundamental frequency coefficient of variation
The term __________ refers to growth changes that occur during puberty in which the neck lengthens and the larynx descends and grows in size.
Mutation
The following component measure is NOT incorporated into the Dysphonia Severity Index (DSI):
Cepstral peak prominence (dB)
The following are important considerations in the measurement of vocal sound level/intensity (in dB):
mouth-to-microphone distance, weighting circuit, ambient noise level, and type of sound level meter (SLM)
________ is a short-term measure of instability that quantifies cycle-to-cycle variations in frequency.
Jitter
Rough voice signals are often characterized by the presence of _________.
subharmonics and amplitude modulations
The cepstral peak within a predetermined range of quefrencies (i.e., a range of periods) is referred to as ________
dominant rahmonic
The ___________ is a graphical representation of the combined frequency and intensity capabilities of the patient’s voice.
