Inworld AI is a developer platform for building realtime voice AI, covering text-to-speech, speech-to-text, and full speech-to-speech agents that respond fast enough to feel like a real conversation rather than a chatbot with a voice bolted on. Inworld AI features its impressive realtime TTS-2 engine, which claims under 200ms latency, supports voice cloning from just 15 seconds of audio, and lets you steer tone, pacing, and emotion using plain-language or bracketed instructions instead of fiddling with tricky model parameters.
To get started, you can sign up on the Inworld platform, grab an API key, and either drop the models straight into a WebSocket/REST integration or test voices first in the browser-based playground
