Purpose: The aims of this study were: (1) to quantify variability in voice production (as measured acoustically) within and across consecutive days in vocally healthy female speakers; (2) to identify which acoustic measures are sensitive to this variability; and (3) to identify participant characteristics related to such voice variability. Method:…

Background: Voice disorders that result in reduced loudness may cause difficulty in communicating, socializing and participating in occupational activities. Amplification is often recommended in order to facilitate functional communication, reduce vocal load and avoid developing maladaptive compensatory behaviours. The most common microphone used…
