Accuracy is the word error rate (WER) the open Open ASR Leaderboard measured for the exact same model (English average, or FLEURS for the selected language); it is not a test of your audio, and rows without an exact match say so. Costs are API usage estimates, not all-in account bills. Includes documented request minimums and known speaker-label charges when required. Excludes taxes, plan fees, credits, retries, storage and other extras. Incomplete language evidence is kept out of a confirmed shortlist. Test representative audio before integrating.

Every rate and its source

These are transcription APIs for developers, not subscriptions to meeting assistants or consumer apps. Lower cost does not establish better recognition accuracy or support for your language.

Rates come from the approved open pricing datasets where they match the provider page, otherwise from the provider's official pricing page. Totals are estimates, not quotes. Recorded and live endpoints are kept separate. Deepgram uses the monolingual pre-recorded rate; premium tiers and audio-token pricing are not converted into flat hourly rates.
