REJECTION PHENOMENA IN INTER-SIGNAL VOICE TRANSPLANTATIONS

摘要

The voice modification system studied in this paper allows to transplant selected voice characteristics (pitch, loudness, timing, and/or timbre) from a given donor utterance onto another (patient) utterance. Several potential applications exist for such a system, depending on the voice characteristics that are transplanted. The examples studied here are lip synchronization, voice dubbing and karaoke. Using overlap-add techniques for the actual speech modification, high quality results have been obtained that convincingly illustrate the potential of voice transplantation. In order to make voice transplantations widely applicable, their robustness should be further improved in order to avoid rejection of the transplanted characteristics, as discussed in some detail in the paper.
