Flux now supports the numerals feature, which converts numbers from written format to numerical format (for example, "nine hundred" becomes "900"). Numerals are available 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.

Set numerals=true as a query parameter when you open the WebSocket connection:

wss://api.deepgram.com/v2/listen?model=flux-general-en&numerals=true&encoding=linear16&sample_rate=16000

On Flux, numerals is set at connection time only and cannot be changed through the Configure message.

See the Numerals documentation and the Flux API Reference for full details.
