Technology Artificial Intelligence Language Model Audio Language Model Editors Pick New Releases Staff Voice AI Voice AI has a dirty secret: most of it was never designed for conversation. The dominant paradigm — feed text in, get audio out — traces its lineage to audiobook narration and voiceover production, where the model never hears the person on the other end.

Inworld AI is calling that out directly with the launch of Realtime TTS-2, a new voice model released as a research preview via its Inworld API and Inworld Realtime API. The model hears the full audio of the exchange, picks up the user s tone, pacing and emotional state, then takes voice direction in plain English the way developers prompt an LLM.
The meaningful architectural distinction with TTS-2 is that it operates as a closed-loop system. The model takes the actual audio of the prior turns of the exchange as input, not just a transcript — it hears how the user actually sounded. That s a non-trivial difference. A transcript of okay, fine gives you the words. The audio of okay, fine tells you whether the person is relieved, resigned, or sarcastic. TTS-2 is designed to use that signal.
