Every voice expert should be able to work in collaboration with artistic phoniatrists and speech therapists, to ensure an integrated and comprehensive approach in managing clients' vocal issues. In particular, in cases of functional dysphonia, which are caused by incorrect use of one's voice, retraining with a vocal coach is crucial. It helps singers and actors learn to use their instrument efficiently and healthily, resolving numerous issues associated with improper usage, and preventing potential future relapses.
