Summary
Objective
A case study was used to determine which acoustic parameters would be sensitive to
a SOVT-based vocal warm-up over the duration of a standard voice treatment.
Methods
The longitudinal research design consisted of repeated voice measures during 7 weeks
from a single subject, a 48-year-old male occupational voice user with a history of
voice disorders. A steady phonation and running speech tasks were performed before
and after an intensive 1-minute water-resistance voice exercise (WRT). Acoustic assessment
of the pre-and postrecordings from each session was obtained with freely accessible
software (e.g., Audacity, PRAAT) and acoustic measures (e.g., fundamental frequency,
jitter, shimmer, alpha ratio, NHR, HNR, L1L0, Cepstral Peak Prominence smoothed).
Results
After WRT, the analysis indicated that jitter, shimmer, and NHR had a small but statistically
significant decrease, while alpha ratio, CPPS, and HNR had a statistically significant
increase. For the days where there were six repetitions, there was a larger effect
in the later repetitions in the day for some metrics (i.e., alpha ratio, shimmer,
NHR, CPPS), while others had the biggest effect in the first two repetitions in a
day (i.e., jitter, HNR).
Conclusions
A short vocal water-resistance voice task had a positive effect on the short-term
acoustic voice metrics after each repetition of the exercise, independent of the number
of repetitions throughout the day. When five repetitions of this exercise routine
occurred, there was a more substantial influence on the proportion of acoustic voice
changes.
