An Automatic Pitch Correction System Based on Spectral Modeling Synthesis Technique
YANG Nan
Abstract：Pitch correction with preservation of timbre has been a difficult technical issue that hinders the development of music applications.To address this problem,a spectral modeling synthesis (SMS)based automatic pitch correction system is proposed.It extracts the pitch contour in real time with voiced/unvoiced decision and pitch detection.The extracted pitch contour is then compared with the reference pitches such that the detuned parts can be determined.Finally,the proposed SMS based method is applied to the voice to correct the pitches,preserving the timbre by preserving the spectral envelop. Experimental results suggest that the proposed system can provide good pitch correction effect.
