Analyzing severely disphonic voices and connected speech

32
Q

What is the magnitude of amplitude of the maximum cepstral peak

A

Cepstral peak prominence (CPP)

33
Q

CPP will be elevated for __________periodic signals

A

Highly

34
Q

CPP will be reduced for ________ periodic signals

A

Less

35
Q

37
Q

ADSV

A

Analysis of Dysphonia in Speech and Voice

38
Q

A

ADSV (analysis of Dysphonia in speech and voice)

39
Q

True or false: ADSV uses the same stimuli as the CAPE-V

A

True

40
Q

The following parameters are calculated during the ADSV:

A

CPP (cepstral peak prominence)
L/H spectral ratio
CSID (cepstral/spectral index of Dysphonia)

41
Q

True or False: Larger values are worse on the CPP

A

False

42
Q

True or false: Larger values are better on the L/H spectral ratio

A

True

43
Q

Ratio of energy below 4000 Hz to energy above 4000 Hz

A

L/H Spectral Ratio

44
Q

This measure provides an estimate of the severity of Dysphonia on a 100 point scale similar to the CAPE-V 100 mm visual analogue scale.

A

(CSID) cepstral/spectral index of Dysphonia
