    Abstract:
    PURPOSE: Intensive voice use may lead to the development of voice disorders or voice complaints, such as vocal fatigue, for professional voice users (teachers, academics, call center workers, actors, singers, speech and language therapists, voice trainers, and religious officials). Vocal fatigue has a detrimental effect on occupational, emotional, and social performance, besides the quality of life of the individual. The effect of voice hygiene interventions on voice fatigue is not fully known. The results of studies conducted with different occupational groups are inconsistent. The present study aims to analyze the relationship between vocal fatigue and voice-related quality of life (V-RQOL) in professional voice users, and the impact of vocal hygiene on vocal fatigue. METHODS: Participants (24 male, 90 female), who were professional voice users without any diagnosis of voice disorders or voice complaints were divided into two groups low vocal hygiene compliance (LVH; n = 66) and high vocal hygiene compliance (HVH; n = 48). In this study, vocal fatigue was measured by the vocal fatigue index (VFI), and V-RQOL was measured by the voice handicap index (VHI-10) and V-RQOL. RESULTS: VFI subscales (tiredness, avoidance, physical discomfort) have a moderate positive correlation with VHI-10 and V-RQOL, which indicates that there is a significant relationship between vocal fatigue and quality of life amongst professional voice users. While there was no significant difference between the LVH and HVH groups in terms of quality of life, it was found that the vocal fatigue level of the LVH group was higher. CONCLUSION: This study of professional voice users with healthy voices reveals a relationship between vocal fatigue and V-RQOL. Vocal hygiene compliance may affect professional voice users' vocal fatigue symptoms; the low-compliant group has higher levels of tiredness, avoidance, and physical discomfort. The findings highlight the importance of raising awareness of the problems of professional voice users, even though they have healthy voices and the need for vocal hygiene education programs that target them.
