Changelog

The Browser Agent SDK never shipped client-side Silero voice activity detection. Documentation published with the SDK described it as an available feature, and that documentation was wrong. The following did not exist in any released package:

• The vad option on MicrophoneOptions in @deepgram/agents.
• The speechThreshold and silenceThreshold VAD options.
• The speech-start and speech-end events on AgentMicrophone.
• The vad field in WidgetConfig and the widget’s VAD configuration section.
• The @ricky0123/vad-web and onnxruntime-web peer dependencies. Uninstall them if you added them for VAD.

The server-side token-minting example on the Browser Agent SDK overview posted {"ttl": 30} to POST /v1/auth/grant. The field is named ttl_seconds:

body: JSON.stringify({ ttl_seconds: 30 }),

/v1/auth/grant accepts unrecognized fields, returns 200, and issues a token with the 30-second default, so a request built from the old example raised no error while ignoring the requested lifetime. If you copied that example and increased the number, your tokens expired after 30 seconds.

We have released nova-3-pharma, a new Nova-3 model purpose-built for pharmaceutical vocabulary, with a focus on accurate drug-name recognition. It is designed for pharmacy and healthcare voice-agent workflows where getting the medication right matters most. Available in English for both batch and streaming.

India Endpoint Now Generally Available

The Deepgram India endpoint (api.in.deepgram.com) is now generally available for customers requiring data processing within India.

Supported APIs

The India endpoint supports the following Deepgram APIs:

  • Minimum required NVIDIA driver version: >=580, open kernel module flavor

    • The minimum driver version has increased this release, up from >=570.172.08. The Engine image is built against CUDA 13, and NVIDIA’s official CUDA 13 support begins with the 580 driver branch. NVIDIA’s documentation states the CUDA 13 minimum as >=580 rather than a specific version.
    • The driver must be the open kernel module flavor, for example nvidia-driver-580-open. The proprietary build of the same version is not supported.
      • On Blackwell hardware the consequence is total: NVIDIA never added Blackwell support to the proprietary 580 branch, so on that build a Blackwell GPU disappears from the system, nvidia-smi reports no devices, and Engine will not start. See Drivers and Containerization Platforms for installation and verification steps.

Deepgram Python SDK v7.9.0, JavaScript SDK v5.11.0, and Java SDK v0.10.0 are now available. All three releases add Voice Agent ForceEndTurn support, Flux TTS expressivity controls for Agent providers, and the expanded Flux TTS speed range of 0.5 through 1.5 in 0.05 increments.

@deepgram/react 0.2.0 adds runtime Voice Agent controls and makes React session lifecycle handling safer. The release updates the React layer for @deepgram/agents 0.1.2 and @deepgram/sdk 5.9.0.

The agent begins building a reply before speech-to-text confirms the user has finished speaking. Agent audio is held until that confirmation, but function calls have always dispatched as soon as the LLM emitted them. For a function with an irreversible side effect, such as ending a call or booking an appointment, that meant the action could run for a turn the user then continued.

We have added Kazakh as a new Nova-3 language and released improved Nova-3 monolingual models for seven existing languages. These updates expand language coverage and enhance transcription quality for batch and streaming workloads.

Flux TTS speed now runs from 0.5 to 1.5 in 0.05 increments, up from 0.85–1.15. The default stays 1.0, and every previously accepted value still works.

The wider range applies everywhere speed is accepted on Flux TTS: the /v2/speak streaming WebSocket (at connection and mid-session with Configure), the /v2/speak batch REST endpoint, and agent.speak.provider.speed in Voice Agent sessions running provider.version v2. A value outside the range is still rejected with SPEED_OUT_OF_RANGE, and one off the 0.05 increment with SPEED_INCREMENT_INVALID.

Flux now gives you full control over how turns end. Beyond Flux’s native end-of-turn detection, you can override it, suppress it entirely, or blend the two — and switch between these modes on the fly, even for a single turn, with a Configure message. Turn-taking goes from a fixed behavior to something you shape around each moment of a conversation.

We have released improved Nova-3 monolingual models for ten existing languages. These updates enhance transcription quality for batch and streaming workloads.

We have added Assamese, Mongolian, and Pashto as new Nova-3 languages and released improved Nova-3 monolingual models for several existing languages. These updates expand language coverage and enhance transcription quality for batch and streaming workloads.

You can now end the current user turn from your own signal instead of waiting for end-of-turn detection.

Deepgram CLI 0.3.0 is now available. It completes CLI support for Flux TTS, which reached general availability on 12 August, fixes Flux STT streaming, and enforces the CLI’s exit-code contract.

Upgrading from 0.2.26 picks up everything in this release. 0.2.27 was tagged but never published, so its changes arrive here.

expressivity for Flux TTS

agent.speak.provider.expressivity shifts a Flux TTS voice’s delivery register along a calm to animated axis. It accepts the whole numbers -2 to 2 and defaults to 0, the voice’s tuned delivery. Negative values produce calmer, steadier delivery; positive values produce more animated delivery with a wider pitch range. Every Flux voice supports it, and the value applies for the whole session.

We have added Afrikaans and Georgian as new Nova-3 languages and released improved Nova-3 monolingual models for several existing languages. These updates expand language coverage and enhance transcription quality for batch and streaming workloads.

Supported languages and language codes:

• Bulgarian (bg)
• Chinese (Cantonese, Traditional) (zh-HK)
• Malay (ms)
• Korean (ko, ko-KR)

You can now use Deepgram’s Numerals feature with monolingual models for Bulgarian, Chinese (Cantonese, Traditional), Malay, and Korean. Numerals converts spoken numbers into digits (for example, “three hundred” → “300”) in your transcript, helping you create more accurate and easily processed results.
