Artificial Analysis launches TTS leaderboard with new Pronunciation Robustness Benchmark across 95 models
ArtificialAnlys · x · 2026-09-24
Artificial Analysis launched a Text-to-Speech comparison page covering 27 of 95 models, comparing quality, speed and price of provider-native voices, ranked by Arena Elo from user votes in its Speech Arena.
It also introduced a new Pronunciation Robustness Benchmark: human reviewers judge the share of English spans pronounced correctly, spanning four categories —
- Standalone terms: brand, place and technical names (e.g. Arkansas, façade);
- Contextual disambiguation: same spelling, different reading by context;
- Plus shorthand expansion and other categories.
Each model is tested with a single voice; prompts are sent as written with no normalization, using the model's default text normalization setting when offered.
