Pulse STT

The legacy numerals query parameter on the Pulse STT WebSocket has been removed from the API reference, navigation, and feature pages. The 2026-05-06 deprecation note on this changelog feed flagged this for two weeks; today’s clean-up drops it from the documented surface area.

What changed in the docs

• numerals removed from the Pulse WS AsyncAPI spec + v4 override.
• The “Numeric formatting” feature page and its nav entry are gone.
• The “Convert numerals” cards on realtime/features.mdx and pre-recorded/features.mdx are gone.
• The ITN feature page no longer lists numerals in its precedence table.

What changed on the server

Nothing in this release. The numerals query parameter still works as before — historic callers passing numerals=true will continue to get the same behavior. This is purely a docs cleanup; future deprecation/removal at the server layer will get its own changelog entry when it happens.

What to use instead

For new integrations, pass itn_normalize=true on the WebSocket connection. ITN covers digits as well as dates, currencies, phone numbers, and other spoken-form entities, and gives more consistent results across languages. See the Inverse Text Normalization page for details.
