Trial outcomes

Primary outcomes

1

Change in Cepstral peak prominence (CPP)

Cepstral peak prominence (CPP) as a robust objective measure of voice quality in the active, sham and no stimulation conditions.

daily on Day 1-Day 5
2

Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V)

Its primary purpose is to describe the severity of auditory-perceptual attributes of a voice problem, in a way that can be communicated among clinicians
