ElevenLabs Changelog

ElevenAgents adds per-agent sentiment analysis settings, auto-translate transcripts, and nested agent transfers with push/pop/replace workflow operations. Workspaces now support programmatic service-account creation, and member listing via new API endpoints. The optimize_streaming_latency TTS setting is deprecated and documented as a no-op.

Simulate conversation and stream simulate conversation endpoints are deprecated in favor of Create test and Run tests on agent endpoints. Added music detailed stream endpoint for SSE streaming with composition metadata and optional word timestamps. Agents now support numeric evaluation scoring, conversation reasoning, interruption modes per-tool, and platform billing breakdown. Optional disableAuth for Speech Engine WebSocket clients is available in JavaScript and Python SDKs v2.56.0.

Agent configuration branches now support merge and rebase preview endpoints to inspect changes before committing, plus branch-level call volume metrics. Speech-to-text multichannel conversion adds a combined output mode for a single sorted transcript across all channels.

Music v2 models now default to higher bitrate mp3_48000_192 output, and new output formats mp3_48000_240 and mp3_48000_320 are supported. ElevenAgents adds per-agent topic discovery, background sound configuration, turn interruption ignore terms, and a branch rebase API. Conversation listing gains product-type and termination-reason filters.

Music v2 introduces chunk-based composition plans for finer control over structure and pacing. ElevenAgents adds conversation evaluation rerun, workflow entry behavior, and end-procedure tools; InteractionBudget enum removes async and adds 5_minutes, 10_minutes, and 1_hour. Plus workspace service account partial updates, studio project voice reference migration, and SDK releases.

The eleven_monolingual_v1 and eleven_multilingual_v1 text-to-speech models are deprecated and will be removed on July 9, 2026, as is scribe_v1. The default ASRConversationalConfig.provider changes from elevenlabs to scribe_realtime, with elevenlabs remaining but deprecated. Turn model configuration adds per-agent and per-workflow selection (turn_v2 or turn_v3, defaulting to v3), soft timeout filler messages support up to 7 additional messages, and knowledge bases now support Google Drive external sync with is_frozen metadata.

Added Exotel as a first-class telephony provider alongside Twilio and SIP trunking, with new outbound call endpoint and phone number management schemas. Agent transfers now support staying on the current agent and targeting specific workflow nodes. Conversation filtering, agent test repeat runs, hCaptcha support for dubbing, 5 GB upload limit for speech-to-text, and SDK updates including configurable microphone chunk duration are also included.

Speech Engine adds real-time voice to custom chat agents and LLMs by handling speech-to-text, turn-taking, and text-to-speech while the server owns the agent logic and streams response text over a WebSocket. ElevenAgents gains text behavior overrides per conversation source, Intercom/Telegram/Freshdesk integrations, OTLP conversation traces, and keyword overrides; Music adds generation modes and video-to-music model selection; packages fix iOS Safari message drops and improve widget transcript styling.
