Objective To explore the impact of voice training and cognitive behavioral therapy using digital intelligence technology on the psychological state, voice training behavior and efficacy in professional voice users with voice disorders, and to promote physical and mental health of this population. Methods From June to December 2024, 68 professional voice users with voice disorders were selected and randomized into a control group and an observation group, with 34 in each group. The control group was given conventional face-to-face voice training, while the observation group received voice training and cognitive behavioral therapy using digital intelligence technology. Both groups received 8-week intervention. These indicators including anxiety, depression, quality of life, voice training behavior, acoustic voice parameters, and vocal fold recovery were assessed at baseline (pre-intervention), 3-week, during the intervention and 8-week immediately after the intervention to compare the effect between the two groups. Results Thirty-three cases in each groups completed the study. At the 8-week immediately after the intervention, the observation group had significantly lower anxiety and depression, higher quality of life, and better voice training behavior, acoustic voice parameters, and vocal fold recovery than the control group (all P<0.05). Conclusion Voice training and cognitive behavioral therapy using digital intelligence technology can improve the psychological state and voice training behavior of professional voice users with voice disorders, resulting in enhancing the training effect.
