Abstract

A system and method for text-to-speech performance evaluation are provided. The method (100) for text-to-speech performance evaluation includes providing a plurality of speech samples and scores associated with the respective speech samples (110); extracting acoustic features that influence the associated scores of the respective speech samples from the respective speech samples (120); training a machine learning model by the acoustic features and corresponding scores (130); and evaluating a text-to-speech engine by the trained machine learning model (140).
