What this deployment accepts through our API. A no means the option is not offered on this model here — not that the vendor has never shipped it.
Languages
It cannot identify the language itself: name one before you run. Several languages in one recording are accepted too.
The vendor’s own parameters
| Parameter | Default | What it does |
|---|---|---|
diarization | unset | Separate speakers by voice, by audio channel, or both. Overrides the universal diarization switch. |
speaker_sensitivity | 0.5 | 0 to 1. Higher finds more distinct speakers, at the cost of splitting one voice in two. |
prefer_current_speaker | unset | Stay with the previous speaker when the acoustic match is close. Reduces false switches and can miss brief interjections. |
max_speakers | unset | Upper bound on distinct speakers. Two or more; ignored below that. |
channel_diarization_labels | unset | Comma-separated names for the audio channels, in order — for example: Agent, Caller. |
output_locale | unset | Regional spelling of the transcript. Set automatically from the chosen language; override it here. |
punctuation_sensitivity | unset | 0 to 1. Higher produces more punctuation. |
permitted_marks | unset | Punctuation marks to allow, separated by spaces — for example: . , ? — or "all". A comma cannot be a separator here because it is one of the marks. Overrides the universal punctuation switch. |

The fare, and what it is worth
We have not read a published fare for this deployment, so there is nothing here we would stand behind. The rest of the sheet is on the comparison page, and Speechmatics states this one on its own pages. What we charge is on our pricing page.
What Speechmatics says about it
Speechmatics' early-access multilingual model: transcribes code-switched audio without being told the language. Batch only, EU and US only, and returns no confidence scores or custom dictionary.
