Test-Retest Reliability of the Dual-Microphone Voice Range Profile

The voice range profile (VRP) measures vocal intensity and fundamental frequency. Phonosurgical and logopedic treatment outcome studies using the VRP report voice improvements of 3–6 semitones (ST) in ST range and 4–7 decibels (dB) in sound pressure level range after treatment.

Description
Summary:The voice range profile (VRP) measures vocal intensity and fundamental frequency. Phonosurgical and logopedic treatment outcome studies using the VRP report voice improvements of 3–6 semitones (ST) in ST range and 4–7 decibels (dB) in sound pressure level range after treatment. These small improvements stress the importance of reliable measurements. The aim was to evaluate the test-retest reliability of the dual-microphone computerized VRP on participants with healthy voices. This is a prospective test-retest reliability study. Dual-microphone VRPs were repeated twice on healthy participants (n = 37) with an interval of 6–37 days. Voice frequency and intensity (minimum, maximum, and ranges) were assessed in combination with the area of the VRP. Correlations between VRP parameters were high (r > 0.60). However, in the retest, a statistically significant increase in voice frequency range (1.4 ST [95% confidence interval {CI}: 0.8–2.1 ST], P
