## 正文

Inworld's newly released Realtime TTS-2 is the new #1 on the Artificial Analysis Controlled Voice Arena, just ahead of Cartesia Sonic 3.6, and ranks #2 on our Provider Voice Arena behind Sonic 3.6

Realtime TTS-2 is a new Text to Speech model from @inworld_ai that supports over 100 languages, including English, Hindi, Spanish, French, German, Chinese, and Japanese. Language can be set explicitly or detected from the text, including multiple languages in a single request (e.g., "I'll grab a coffee. ¿Quieres uno? お疲れさま。"). It also supports delivery instructions written in plain text alongside the input (e.g., [speak tired but warm, like she just got home from a long day]).
