Benchmark Almanac

Artificial Analysis Speech Arena

Voters listen to two speech clips made from the same text and pick the more natural one. Votes become Elo ratings.

Artificial Analysis runs it. The almanac lists that it exists but imports no Artificial Analysis data, because its terms bar reuse in ranking products.

Only Gemini 3.1 Flash TTS has a rating here, from its lab’s own post

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs. A rating ranks a model only against others rated in the same arena at the same time, so these don’t show who leads. Artificial Analysis doesn’t allow reuse of its data, so we link to its board instead. See the live leaderboard on artificialanalysis.ai
