FireRedTTS

LLM-empowered foundation text-to-speech system and the FireRed team's first open release, launched well before the dots family. FireRedTTS2 (September 2025, arXiv:2509.02020) extended the line to long-form streaming TTS for multi-speaker dialogue generation. The TTS stack underpins FireRedChat, the team's self-hosted full-duplex voice interaction system.
