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.SpeechifyHighest-scoring row in this table on the Artificial Analysis Speech Arena (1240 ELO, rank 3 of 99), with low measured latency (398 ms P50 in the Coval capture, 3.4% WER), flat per-character pricing, and streaming, SSML and voice cloning from the entry tier; 50K characters/month free. Plan-bundled pricing: the $10/1M rate is the Starter overage (Pro $8/1M, Scale $6/1M), so effective cost depends on tier and is marked not directly comparable; the 30+ language count is a platform-wide claim rather than a Simba-specific spec, and the production ecosystem is younger than ElevenLabs'.
