Is it true that delayed auditory feedback of a person's own voice disrupts fluent speech?
Yes. Multiple sources state that delayed auditory feedback of a speaker's own voice disrupts normal speech production, producing artificial stuttering and reduced fluency in fluent speakers. Some items concern DAF's effects on stutterers' fluency rather than disruption of normal speech.
