Vendor intelligence
Rime
Conversational TTS with separate models and enterprise deployment options.
Read the signals. Keep the scope.
A place in your stack.
Best for
- Teams evaluating pronunciation control for names and identifiers
- Developers needing a speech layer with private-deployment discussions
Watch-outs
- The free allowance and catalog counts conflict on official pages.
- Coda and Mist have different character rates; neither is an all-in call price.

Unknown means we have not established it. It does not mean No. Compliance claims require plan and contract review.

Reviewed field-specific candidate passages and product, API, pricing, privacy, deployment, metrics and integration documentation.

Inspect detailed evidence, sources and research gaps
September 2026 remains the historical baseline. A new research date does not mean a feature launched that day. Unknown after research and not researched are separate states.
Official documentation establishes what the supplier documents. No paid calls, independent product benchmarks or compliance audits were performed in this research pass. Coverage measures research work, never product quality.

Price structure
Characters / credits
V3.3 evidence review · Mist TTS; Coda separately priced; catalog and free-credit conflicts remain
Mist and Coda are billed per characters. Approximate minutes are supplier illustrations, not normalized all-in phone rates.
Human fallback
Unknown — no established fallback mode
Not applicable to this product scope. The reviewed product is the speech-generation layer. Calling, recognition, conversation orchestration, routing and call artifacts belong to the surrounding application/providers. Not applicable to this component scope; do not interpret as a claim that a custom full stack cannot implement it.
Documented transfer is not a staffed human service. Verify who answers, when they answer and what happens if they do not.
Try it yourself
Unknown — no independently checked public demo entry is attached.
External signals
No dated external signal in this record. Missing evidence is not a negative review.
Underlying model context: the documented stack above does not establish an exact benchmark checkpoint or its deployed settings. Public model results cannot become a Rime score.

New research observations preserve earlier captures. “Evidence improved” records what we learned; it does not claim the market changed on that date. September 2026 is the historical baseline.

Rime pricing and model comparisonunresolved
Mist v3 is $0.03/1K characters and Coda $0.05/1K. Enterprise lists BAA, SOC 2 reports and private deployment. Free allowance conflicts: header says roughly 800 minutes, FAQ 3,000. Voice and language totals also conflict between the model table and FAQ. No audio-minute conversion is used here.

Rime offers Coda and Mist speech APIs, streaming, pronunciation controls and Enterprise custom voice cloning. It lists Coda at 8 languages/184 voices and Mist at 4 languages/78 voices; the pricing page instead lists 94 Mist voices. Aggregate catalog counts require clarification.
