A challenge for promoting automatic prediction of subjective ratings for voice.
Human listening tests are the gold standard for evaluating speech. Objective measures of speech quality have a low correlation with human ratings, and the generalization abilities of current data-driven quality prediction systems suffer significantly from domain mismatch. The VoiceMOS Challenge was founded in 2022, and we aim to encourage research in the area of automatic prediction of mean opinion score (MOS) for synthesized speech.
