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.

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.

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.
