InjectAgentMessage: behavior field and new interrupt mode

The InjectAgentMessage message now accepts a behavior field that controls how an injected message interacts with any in-progress user or agent turn. The default and queue behaviors were previously documented; the new interrupt behavior is introduced with this release.

🆕 Profanity Filtering for Multilingual Models

Deepgram’s Profanity Filtering feature is now available for all multilingual models: Nova-2 multilingual, Nova-3 multilingual, and Flux multilingual (language=multi).

When enabled, inappropriate language is automatically replaced with asterisks (****) in the transcript.

We’re excited to announce the release of profanity filtering support for over 50 monolingual languages. Deepgram’s profanity filter automatically detects and redacts offensive language in transcripts, helping you produce cleaner and safer content across a wide range of languages.

A new batch diarization model is available today via the diarize_model API parameter.

Deepgram is rolling out v2 of our batch speaker diarization model. v2 is a new architecture available today on an opt-in basis through the new diarize_model parameter. In side-by-side human evaluation, v2 was preferred 3.3× over our current production diarizer (v1), with the largest gains on contact-center audio — median CER reduced roughly 80% compared to the prior version of the diarization model. Customers using diarize=true are unaffected.

A new round of SDK updates is now available across JavaScript, Rust, Python, and Java. This release brings Flux multilingual support to Rust, restores the Agent interface in JavaScript, ships a Python bugfix for WebSocket query parameters, and delivers a breaking Java release with reconnect improvements.

Numerals Support Expanded for Nova-3 Multilingual

Numeral formatting is now supported for all Nova-3 multilingual languages — except Hindi and Japanese. This enhancement means Nova-3 multilingual can now convert spoken numbers to digits (e.g., “three hundred” → “300”) for English, Spanish, French, German, Russian, Portuguese, Italian, and Dutch.

The Browser Agent SDK is now available — four composable packages that connect any web app to the Voice Agent API:

• @deepgram/agents-widget — drop-in widget with six layouts (sidebar, floating, inline, button, embedded, or orb). No framework required.
• @deepgram/ui — pre-built React components (conversation view, animated orb, mic/speaker controls, waveform visualizer) styled through CSS custom properties.
• @deepgram/react — provider + hooks for state, conversation history, microphone control, audio playback, and client-side function calling.
• @deepgram/agents — the framework-agnostic core: WebSocket client, microphone capture, and player.

The Voice Agent section has been reorganized into five sections — Get Started, Build, Integrate, Reference, and Tips & Migration — to make it easier to find content based on where you are in your build. As part of the same pass, a few closely related reference pages have been merged (for example, prompt-updated, speak-updated, and think-updated are now consolidated into Acknowledgements, and the errors and warning pages are now Errors & Warnings). Redirects are in place, so existing links continue to work.
