Speech processing is widely used in the research for last two decades, with an increasing commercial interest and applications of VC such as Speech-to- Speech Translation (SST), and Text-To-Speech (TTS). More traditional methods are available for voice conversion, but they do not provide better converted speech; such as GMM doesn't generate high quality converted voice because GMM based VC creates over-smoothing. Hence in this research, the authors have proposed a new voice conversion algorithm, Minimum Distance Spectral Mapping (MDSM) based on the idea of Dynamic Time Warping (DTW), where point-to-point mapping is used in the warping function. Also amplitude scaling function is intended to adjust mean source log amplitude spectrum to the mean target log amplitude spectrum, in order to reduce over-smoothing. Since most of the spectral envelopes in amplitude scaling mean log spectral envelopes are smooth, there is no necessity in finding the smoothing factors. The proposed MDSMAS preserves spectral details, provides improved speech quality and identifies the similarity between source and target data and also provides improved result in objective tests.
