# Inworld Releases Realtime TTS-2 for Voice Agents

> Inworld has launched Realtime TTS-2, a text to speech engine aimed at live voice agents. It generates speech with latency under 100 milliseconds at the 99th percentile, and a lighter Flash variant returns its first audio in about 25 milliseconds, fast enough to feel like a real back and forth. Beyond speed, the model takes plain language delivery instructions and inline cues like laugh, breathe and sigh to shape tone, and it can clone a voice from just 5 to 15 seconds of audio while preserving that voice across more than 100 languages. Voice is quietly becoming the main interface for AI assistants, and the hard part has always been sounding natural without an awkward pause. At $25 per million characters, TTS-2 is Inworld's pitch that expressive, low latency speech is now cheap enough to put in everyday products.
