VoiceMOS Challenge 2024

News

Founded in 2022, the VoiceMOS Challenge (VMC) series aims to use standardized datasets in diverse and challenging domains to understand and compare prediction techniques for human ratings of speech, specifically those collected through a mean opinion score (MOS) test. The main motivation is to foster development in automatic, reference-free, and data-driven speech quality assessment approaches, to overcome the costly and time-consuming human listening tests that are conventionally regarded as the gold standard for evaluating synthesized and processed speech such as text-to-speech synthesis (TTS), voice conversion (VC), and speech enhancement (SE).

This year's challenge is a collection of three tracks, as described below. Like previous challenges, the primary evaluation metrics for MOS prediction will focus on correct ranking of synthesis systems in each track. As usual, there is no participation fee. Also, this year the challenge will be held on CodaBench (https://www.codabench.org/). If you have participated in the previous VMCs, CodaBence is an upgraded version of the CodaLab platform.

Tracks

Track 1: MOS prediction for "zoomed-in" systems

The first track aims to predict the MOS of a “zoomed-in” subset comprising the top systems in the BVCC dataset collected through a separate listening test. We believe this track reflects the need of present-day speech synthesis researchers to compare only high-quality synthesis systems. 

Track 2: MOS prediction for singing voice

The second track is based on a new dataset containing samples and their ratings from singing voice synthesis and conversion systems. This track can be regarded as an extension of the SVCC track in VMC 2022, with a larger variety of systems, listeners, and languages.

Track 3: Semi-supervised MOS prediction for noisy, clean, and enhanced speech

The third track is semi-supervised MOS prediction for noisy, clean, and enhanced speech. Participants will only be allowed to use a very small amount of MOS-labeled data provided by organizers.
