Agent Framework plugin for voice synthesis and speech-to-text with Inworld's API.
Decision gist · record as of 2026-08-14
Yes, if you are building a LiveKit voice agent and want to use Inworld's TTS and STT APIs. The package is actively maintained, has no known vulnerabilities, installs cleanly with minimal dependencies, and the Apache-2.0 license is permissive. The main prerequisite is an Inworld API key and willingness to use their services; evaluate Inworld's pricing and model quality for your use case before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires INWORLD_API_KEY environment variable set in .env file; obtain from https://platform.inworld.ai/login.
- Requires Python >=3.10.0.
- Low friction: pure Python wheel with a single runtime dependency (livekit-agents).

What it is and what it does
This package is a LiveKit Agents plugin that wraps Inworld's text-to-speech and speech-to-text APIs, allowing you to build voice agents that synthesize speech and transcribe user input using Inworld's models. It handles the integration plumbing so you can drop Inworld TTS and STT components into a LiveKit AgentSession alongside an LLM and other agent logic.
The TTS side supports multiple voice IDs, encoding formats (LINEAR16, MP3, OGG_OPUS, ALAW, MULAW, FLAC), sample rates, and real-time streaming via WebSocket with buffering controls for lower-latency synthesis. The STT side provides streaming speech-to-text with optional voice profile detection. Both are designed to work within LiveKit's real-time agent framework, so you configure them as session components and let the framework handle audio routing.
Use it for
- Build a voice agent that listens to user speech, transcribes it with Inworld STT, processes it through an LLM, and speaks back using Inworld TTS.
- Stream text incrementally to Inworld TTS as it's generated by an LLM, reducing latency in conversational interactions.
- Integrate Inworld's voice synthesis into an existing LiveKit agent to replace or supplement other TTS providers.
- Deploy a multi-modal agent that combines LiveKit's video/audio infrastructure with Inworld's speech models for real-time conversations.
- Use voice profile detection with Inworld STT to identify speaker characteristics during transcription in multi-participant sessions.
