The Objective Vocal Quality, Vocal Risk Factors, Vocal Complaints, and Corporal Pain in Dutch Female Students Training to be Speech-Language Pathologists During the 4 Years of Study

SummaryThe purpose of the present cross-sectional study was to determine the objective vocal quality and the vocal characteristics (vocal risk factors, vocal and corporal complaints) in 197 female students in speech-language pathology during the 4 years of study. The objective vocal quality was measured by means of the Dysphonia Severity Index (DSI). Perceptual voice assessment, the Voice Handicap Index (VHI), questionnaires addressing vocal risks, and vocal and corporal complaints during and/or after voice usage were performed. Speech-language pathology (SLP) students have a borderline vocal quality corresponding to a DSI% of 68. The analysis of variance revealed no significant change of the objective vocal quality between the first bachelor year and the master year. No psychosocial handicapping effect of the voice was observed by means of the VHI total, though there was an effect at the functional VHI level in addition to some vocal complaints. Ninety-three percent of the student SLPs reported the presence of corporal pain during and/or after speaking. In particular, sore throat and headache were mentioned as the prevalent corporal pain symptoms. A longitudinal study of the objective vocal quality of the same subjects during their career as an SLP might provide new insights.
