Abstract
In this study, the influence of recording systems on the important clinical voice parameters of jitter and shimmer was examined. Simulated voice samples (i.e., triangular waveforms) of 100 Hz, 200 Hz, and 400 Hz were captured through analog cassette recording, digital audiotape (DAT) recording, and direct-to-computer sampling. Results indicated that the analog recording introduced a statistically significant amount of jitter and shimmer error into the analysis as compared to DAT and direct-to-computer recording. Findings support the use of DAT recorders and direct-to-computer captures in the context of select voice assessment.
