On this benchmark by @voicearena_ai, speech models (TTS) are ranked much the way you’d test a voice with a friend: play two clips, ask which one sounds right.

And now Voice Arena ranks TTS models using only Native-speaker-only voting.
So e.g. Indian English now has its own TTS leaderboard, judged by people who speak it every day.

They score it the same way as its other language boards: vetted native listeners vote blind between two clips, and Bradley-Terry turns those votes into a ranking.

They have also added French, German, Tagalog and Bahasa to its TTS leaderboard, and ElevenLabs ranks first on all 5 boards.
