Strengths & caveats

GoogleHighest-scoring row in this table on the Artificial Analysis Speech Arena (1212 ELO, rank 5 of 99), combined with a low effective per-character cost. Token-based pricing (unchanged at $1/1M input text tokens + $20/1M audio output tokens, billed at 25 audio tokens per second); the ~$12/1M-chars figure is a third-party conversion estimate, not a provider per-character rate, so vergelijkbaar=false. Still labelled a Preview model on Google's own pricing page, with more restrictive rate limits. No independent TTFA: Gemini TTS is absent from the Coval benchmark, where Google appears only as chirp-3-hd at 484ms P50. No native voice cloning.MiniMaxStrong multilingual quality with accurate voice replication; the HD tier ranks in the upper part of the Artificial Analysis Speech Arena, and pricing is clean per-character. Per-character pricing differs sharply by tier: Turbo ~$78/1M vs HD ~$130/1M, and the ELO-ranked variant is the more expensive HD model — so the cheapest tier and the benchmarked tier are not the same. No independent TTFA; flagship-specific ELO and language count not confirmed (left null).
