In this paper, we present a transplantation system that can be used to interchange selected prosodic features among repetitions of the same utterance by the same speaker. The system is based on a 'waveform vocoder' that allows high quality prosodic modifications of speech, and uses DTW for proper time alignment of transplanted features. The quality of the transplantation system is evaluated in relation to the underlying waveform vocoding model. Applications to the study of a number of important problems in text-to-speech synthesis and speech perception are suggested.
