மருத்துவ அறிவியல் மலர்: Redirected phonation in voice therapy is a technique where Dr. M. Kumaresan uses a patient's natural, non-speaking voice sounds, like a cough, laugh, snoring or a gargle, and redirects them into a speaking voice. This technique helps establish an easier, more efficient, and less strained method of vocalizing for people with voice disorders like puberphonia by starting with a familiar sound and then transitioning it to intentional speaking.
