The chant-talk method for voice therapy is a technique used to help individuals improve their vocal abilities, particularly those who have voice disorders or challenges. It is not explicitly detailed in the provided information, but based on the context given, it might involve the use of rhythmic or repetitive speaking patterns similar to chanting to aid in voice production and training. The information refers to various methods of communication and therapy, such as how Broca examined the use of a repetitive syllable in communication, the principles of the talk test for determining exercise intensity, and how language plays a role in therapy for substance addiction.
