Establishing normative voice characteristics of younger and older adults
Keywords:Calculated values, Measured parameters, Older adults, Sound pressure level, Voice characteristics
AbstractA study was conducted to demonstrate the establishment of normative voice characteristics of younger and older adults. It used a new and unique program, called SpeechClinic to record voice samples. SpeechClinic displayed calculated values when a voice sample was recorded. These calculated values included average pitch, length of phonation, and sound pressure level for each task. The algorithms used by the program for performing analyses were well-established and the measured parameters were comparable with most other values. The program allowed the presentation of this information for a given patient, which was useful in monitoring treatment progress. The main objective of the study was to obtain a large number of acoustic voice measures for healthy younger and older adults and provide information about the distribution of these voice characteristics.
