Deepgram’s Numerals feature converts numbers from written format to numerical format. For example, the cardinal number “nine hundred” would appear in your transcript as “900”, and the ordinal number “nine hundredth” would appear in your transcript as “900th”.

Flux support
Section titled “Flux support”Numerals are supported on both Flux models:
- Flux English (
model=flux-general-en) — full numeral formatting. - Flux Multilingual (
model=flux-general-multi) — numeral formatting for English, Spanish, French, German, Russian, Portuguese, Italian, and Dutch. Numeral formatting is not currently supported for Hindi or Japanese.
On Flux STT, set the initial value with the numerals query parameter when you open the connection. To change it mid-stream, send a Configure message.
wss://api.deepgram.com/v2/listen?model=flux-general-en&numerals=true&encoding=linear16&sample_rate=16000Enable Feature
Section titled “Enable Feature”To enable numerals, when you call Deepgram’s API, add a numerals parameter set to true in the query string:
numerals=true
To transcribe audio from a file on your computer, run the following cURL command in a terminal or your favorite API client.
Toggling Numerals during a real-time stream
Section titled “Toggling Numerals during a real-time stream”On the streaming API (/v1/listen), you can turn Numerals on or off at any point during the stream. Send the following JSON message to the WebSocket:
{
"type": "Configure",
"features": {
"numerals": true
}
}Numerals can be turned on and off multiple times during a stream if desired.
Toggling Numerals during a Flux STT stream
Section titled “Toggling Numerals during a Flux STT stream”On Flux STT (/v2/listen), send numerals as a top-level field in a Configure message, alongside type. Flux STT rejects the /v1/listen form nested under features and closes the connection.
{
"type": "Configure",
"numerals": true
}Flux STT replies with a ConfigureSuccess message that echoes the full active configuration, including numerals. The update applies to transcripts Flux STT sends after it processes the message; it doesn’t reformat transcripts it has already sent. You can toggle numerals as many times as needed during a stream.
