Strengths & caveats
ElevenLabsLargest production adoption and most mature voice-library/cloning ecosystem, with both instant and professional cloning; Eleven v3 is the strongest ElevenLabs model on the Artificial Analysis Speech Arena at 1179 ELO (rank 12 of 99). Most expensive per-character of the comparable group ($100/1M chars at $0.10/1K, charged for both Eleven v3 and Multilingual v2); the $0.05/1K Flash/Turbo and v3 Conversational tiers are cheaper but different models. Independent Coval TTFA is slow for the flagship tiers: 653ms P50 for Eleven v3 and 1262ms for Multilingual v2, against 212ms for the cheaper Flash v2.5 — the 264ms previously listed here was a Turbo v2.5 figure, not a flagship one. Language counts differ per model on the pricing page (29 for Multilingual v2, 32 for Flash/Turbo, 70+ for Eleven v3); the 29 shown is the Multilingual v2 figure. Multilingual v2 ranks only 33rd on the Arena (1104 ELO).DeepgramLow, clean per-character price (unchanged at $0.030/1K, $0.027/1K at Growth tier) aimed at voice-agent/IVR workloads with streaming and a large English voice catalog (40+ EN voices). Narrow language coverage, confirmed in the docs at 7 (EN, ES, NL, FR, DE, IT, JA). Independent Coval TTFA improved from 313ms to 293ms P50 — second-best in this table behind Cartesia — but still far off the vendor's '90ms' claim. Aura-2 itself is unranked on the Speech Arena, so naturalness ELO is left null; Deepgram's newer Flux TTS does appear but only at rank 59 (1054 ELO) and costs more at $0.045/1K after a free period ending 2026-09-12. No voice cloning.
