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 Python SDK v7.9.0 adds send_force_end_turn() and typed ForceEndTurn messages for Voice Agent sessions using a Deepgram V2 (Flux STT) listen provider. It also adds integer Agent Flux TTS expressivity from -2 through 2 and the expanded Flux TTS speed range. The unsupported aura-2-perseo-it model is removed from Speak V1 model literals; the API never served that model.

For release details, see deepgram-python-sdk v7.9.0.

Deepgram JavaScript SDK v5.11.0 adds socket.sendForceEndTurn() and Agent Flux TTS expressivity from -2 through 2. The former SpeakV2Speed constants and Aura2PerseoIt model constants remain as deprecated aliases for source compatibility.

For release details, see deepgram-js-sdk v5.11.0.

Deepgram Java SDK v0.10.0 adds sendForceEndTurn(...), Agent Flux TTS expressivity, and the expanded Flux TTS speed range.

This pre-1.0 release includes breaking changes: it removes SpeakV2Speed and its named speed constants, plus the unsupported AURA2PERSEO_IT model constants and visitor methods. Configure speed directly with a numeric value, such as .speed(1.05), and use a supported Speak V1 model.

For release details, see deepgram-java-sdk v0.10.0. For migration steps, see the v0.9 to v0.10 migration guide.
