7th International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2011)
The aim of the present study was to
evaluate patient-report of vocal discomfort by means
of a portable device, designed for the continuous
assessment of voice disorders with real-time coupling
of acoustic and patient self-evaluation measures.
10 teachers were equipped with the portable device embedding our vocal discomfort software during 3 days in their professional settings. They had to note their vocal discomfort during the day on a visual analogue scale (vas) ranging from 0-100 units, either spontaneously, or following an auditory prompt.
The adequacy of the device and of the software was evaluated by a questionnaire addressing the wearability of the device, the easiness of the software, the adequacy of the scale and the subjects' annotation behavior. The adequacy of the scale was further examined by the analysis of the vocal discomfort ratings and their change in value across time. the results show good wearability, easiness, and annotation behavior scores, subjects made regular annotations even without auditory prompting. The discomfort scores generally increased during a working day.
The real-time embedded tracking of patient reported vocal discomfort in professional settings can thus be advantageously performed by a portable device, embedding our auto-evaluation software.
Index Terms. vocal discomfort, real time embedded tracking.
