AI voice generation platform for creating realistic text-to-speech and voice cloning.

ElevenLabs is turning voice agents into versioned software, with weekly API surface to prove it.

voice-agentsdubbingapi-firstversioningspeech-synthesisdeprecations
◆Current state
The changelog is dominated by ElevenAgents, shipped as dense weekly API digests rather than feature posts. Agents now have branches, merges, rebases and version filters, plus procedures that compile into workflows, knowledge-base crawl jobs and per-agent sentiment analysis. Alongside that, the core model lines keep advancing: Music v2, Speech Engine, and now Dubbing v2 through the API.
◆Where it's heading
Two arcs run in parallel. The agent platform is acquiring the mechanics of source control, which points at teams operating many agent versions in production rather than one hand-tuned assistant. The model lines are being rebuilt one at a time and exposed API-first, with older v1 models given explicit removal dates. Dubbing is the newest line to make that jump.
◆Prediction
The v1 deprecation pattern suggests dubbing_v1 gets a removal date next, and the branch tooling looks close to gaining an approval or promotion step given merge previews already exist.

◆Recent moves

  1. 9d ago

    Dubbing v2 API

    ⚡ SPARK

    Dubbing v2 reaches the API, making dubbing the third core model line after music and speech to be rebuilt and shipped API-first this quarter.

  2. 16d ago

    Per-test tool mocks, translated workflow messages, version filters

    Follow-through on the agent-testing and workflow work: per-test tool mocks with failure paths, translated Say-node messages, conversation filters by agent version, and a knowledge-base system tool. Incremental surface on top of the procedures release the week before.

  3. 23d ago

    Procedure APIs, knowledge-base crawl jobs, bulk document management

    ⚡ SPARK

    Procedures arrive as a first-class authoring primitive with eight branch-scoped APIs, sitting alongside new knowledge-base crawl jobs and bulk document management. This is the release that gave agents a compilable unit of behavior.

    Per-agent sentiment analysis, nested transfers, backchannel detection

    Per-agent sentiment scoring, transcript auto-translation, nested agent transfers with push/pop/replace, and backchannel detection. Solid operational depth for teams already running agents at volume.

  5. 1mo ago

    Branch merge and rebase previews, unified auth connection status

    Merge and rebase previews let teams inspect a resulting agent configuration before committing, and auth connection status is unified across all credential types. The source-control analogy gets more literal.

  6. 1mo ago

    Branch rebase, conversation product and termination filters

    Branch rebase lands, along with conversation filtering by product and termination reason. The groundwork for the merge previews that followed a week later.
