On the integrity of the Arabic TTS Arena leaderboard

An audit of the Arabic TTS Arena leaderboard began after users reported that highly rated voices did not match their experiences, particularly following a July 23 surge in which Audar-TTS-V1-Pro won 91 of 92 battles. Although the voting pattern initially appeared manipulative and would have dropped Audar from second to fifteenth place under a proposed filtering rule, reviewers found that the votes were legitimate because the model performed especially well on Saudi and Gulf Arabic prompts. Analysis of all prompts using a dialect classifier showed that model performance varied substantially by dialect: AIC TTS led on Modern Standard Arabic, which comprised nearly two-thirds of votes, while different models led Gulf, Egyptian, Levantine, and Maghrebi categories. Rather than delete any of the 6,622 votes, the platform introduced dialect-specific leaderboard filters, added more regionally representative test sentences, and emphasized that some dialect rankings remain uncertain because of limited data, including Audar’s Gulf result outside the spike day. The authors present the episode as evidence that aggregate benchmarks can obscure meaningful linguistic differences and encourage continued community voting, feedback, and scrutiny through auditable votes and open-source rules.
