Abstract

A real-time vocal manipulation system is described for improving karaoke. Karaoke is an interactive entertainment system where users sing along with recorded music, and it is used all over the world. However, although the users should sing with accurate pitch, it is difficult for the tone-deaf people to sing with accurate pitch. In this paper, a real-time vocal manipulation system is proposed to help tone-deaf people. The system consists of vocoder-based voice synthesis method that can synthesize the voiced sound with fundamental frequency (pitch) and spectral envelope (timbre). Vocal manipulation is achieved based on pitch transcription by replacing the pitch of a tone-deaf person with that of a professional singer. Subjective evaluation is carried out to verify the effectiveness of the proposed system. The results suggested that the proposed system can manipulate vocal sounds in real time.
