What Inworld AI does

Inworld AI is a voice AI platform that combines speech-to-text, large language models, and text-to-speech into unified, low-latency pipelines for production applications. Developers can run full-duplex voice conversations through a Realtime API over WebSocket, building natural, human-like spoken interactions into their products.

Key capabilities

  • Real-time text-to-speech and speech-to-text, including voice profiling for attributes like pitch and emotion
  • Voice cloning from short audio samples with cross-lingual identity support
  • Access to a large catalog of language models through a single OpenAI-compatible endpoint
  • Natural-language steering of tone, emotion, speed, and articulation
  • Streaming with word and viseme timestamps for lip-sync animation

Who it's for

Inworld AI targets developers building voice-driven AI products, including AI companions and character chat, customer support and sales voice agents, phone agents, language-learning tools, and interactive media. The platform emphasizes integrated, low-latency voice infrastructure that can scale for consumer-facing applications.
