Abstract

Objective. This study examines factors predicting self-reported voice symptoms in call center workers. Methods. Multivariate analysis and predictive modeling assess personal, work-re­lated, acoustic, and behavioral factors. Generalized Linear Models (GLMs) and Re­ceiver Operating Characteristic (ROC) curves are employed. Results. Age and sleep patterns impacted voice quality and effort, while workplace factors influenced symptom perception. Unhealthy vocal behaviors related to tense voice and increased effort, while hydration was protective. Voice acoustics showed diagnostic potential, supported by ROC data. These findings emphasize voice symp­tom complexity in call center professionals, necessitating comprehensive assessment. Limitations. This study recognizes its limitations, including a moderate-sized con­venience sample and reliance on PROM metrics. Future research should incorporate more objective measures in addition to self-reports and acoustic analysis. Value. This research provides novel insights into the interplay of personal, occu­pational, and voice-related factors in developing voice symptoms among call center workers. Predictive modeling enhances risk assessment and understanding of indi­vidual susceptibility to voice disorders. Conclusion. Results show associations between various factors and self-reported voice symptoms. Protective factors include sleeping more than six hours and consistent hydration, whereas risk factors include working conditions, such as location and behav­iors like smoking. Diagnostic models indicate good accuracy for some voice symptom PROMs, emphasizing the need for comprehensive models considering work factors, vocal behaviors, and acoustic parameters to understand voice issues complexity.
