# Toggle Numerals Mid-Stream on Flux STT

By Steven Van · 2026-09-25

Voice app developers can toggle digits versus words on a live Flux STT stream, on the English model and eight languages of the multilingual one.

Flux STT can now switch numerals on or off partway through a stream, so a PIN, phone number or order number can come back as digits and the next stretch as words, without reconnecting.

[Deepgram](<https://creatorstoolbox.com/tools/deepgram>) [added the option](<https://developers.deepgram.com/changelog/2026/9/25#toggle-numerals-mid-stream-on-flux-stt>) to the Configure message. To change it during a stream, send numerals as a boolean: { "type": "Configure", "numerals": true }. The change applies to transcripts Flux STT sends after it processes the message.

- ConfigureSuccess now includes numerals in the full active configuration it echoes.

- The numerals query parameter still sets the initial value when the stream opens.

- This replaces the connection-time-only behaviour described in the July 17 entry.

- Mid-stream numerals work on flux-general-en, and on flux-general-multi for English, Spanish, French, German, Russian, Portuguese, Italian and Dutch.
