The present paper presents preliminary results on temporal coordination of breathing, intensity and fundamental frequency signals using continuous wavelet transform. We have found tendencies towards phase-locking at time scales corresponding to several prosodic units such as vowel-to-vowel intervals and prosodic words. The proposed method should be applicable to a wide range of problems in which the goal is finding a stable phase relationship in a pair of hierarchically organised signals.
