TTS Arena expands to 9 languages: Cartesia Sonic leads 8, Inworld tops Mandarin at 1185 Elo
ArtificialAnlys · x · 2026-09-23
Artificial Analysis extended its TTS arena to 9 new languages with 100,000+ human preference votes and per-language Elo rankings. Cartesia's Sonic family tops 8 of 9 boards (Sonic 3.6 leads 7), while Inworld's Realtime TTS-2 ranks #1 in Mandarin (1185 Elo vs Sonic 3.6's 1146) and English. ElevenLabs' Eleven v3 family hits top 3 in 7 of 9 languages. Key takeaway: strong English TTS does not guarantee quality elsewhere.
