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.

Credit billing: one credit equals $1; usage measured by product hours/seconds. This does not mean a character-priced TTS rate or flat agent minute rate.

UnknownUnknown after research · 2026-09-28

No individually verified capability establishes this selection. Conditional support and vendor claims do not satisfy Strict Must-have.

Current captured product corpus; not a universal unsupported claim

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 Speechmatics score.

Append-only price history

Every capture leaves a trace.

A new check creates a new snapshot. Deltas appear only for the same currency, unit, model and scope.
