For this condition, only the Cinderella fable was used. It was divided into 19 individual phrases. Subjects listened to a repeating loop in which a single phrase was uttered, and after the second repetition, they joined in, repeating the phrase six times in synchrony with the target. They wore headphones through which a binaural mixture of their own voice and the target were heard. This methodology was originally developed as a pedagogical tool in teaching prosody, especially pitch accents, to learners of Swedish as a second language [3]. It ought to produce a close match in timing and intonation to the given target. The recording released is the penultimate repetition, together with the target (left and right channels). In the case of dysfluencies, a fluent production preceding the penultimate was used.
