AN AUTOMATIC DONOR RANKING AND SELECTION SYSTEM AND METHOD FOR VOICE CONVERSION

摘要

An automatic donor selection algorithm estimates the subjective voice conversion output quality from a set of objective distance measures between the source and target speaker's acoustical features. The algorithm learns the relationship of the subjective scores and the objective distance measures through nonlinear regression with an MLP. Once the MLP is trained, the algorithm can be used in the selection or ranking of a set of source speakers in terms of the expected output quality for transformations to a specific target voice.
