Abstract
In this paper we deal with initial experiments on creating a new Czech voice conversion system. VC is a process which modifies the speech signal produced by source speaker so that it sounds like target speaker. Using VC technique a new voice for speech synthetizer can be gained with no need to record a huge amount of new speech data. The transformation is determined using equal sentences from both speakers; these sentences are time-aligned using modified DTW algorithm. The conversion is divided into two independent stages corresponding to the source-filter model of speech production. We employ conversion function based on GMM for transforming the spectral envelope described by LSFs. Residua are converted using so called residual prediction techniques. Unlike in other similar research works, we predict residua not from the transformed spectral envelope, but directly from the source speech. Four versions of residual prediction are described and compared in this study.
