Rime's Coda is $50 per million characters; Arcana is $40 and Mist is $30. The model is genuinely tuned for enterprise call use cases. SpeechifyAI covers the same real-time conversational profile from $6 per million characters, well under any Rime tier, on a catalog of 1,500+ voices and 30+ languages, with SSML plus phoneme overrides handling the pronunciation cases that enterprise calls trip on.
Rime's Enterprise tier includes unlimited custom voice clones, but the lower tiers do not. SpeechifyAI includes professional voice cloning starting on Starter at $10 a month, on the same per-character rate as the rest of the catalog, with the same API and the same documentation, so a team that wants conversational TTS plus a brand voice covers both without a tier upgrade or a separate contract.
