Fish Audio S2

Fish Audio S2 open TTS hits sub-150ms latency

Fish Audio S2 is a fully open-source TTS model with inline emotion control via free-text bracket tags like gasp, laughter, and long pause. Alex demoed it live with an OpenClaw skill that let his 5-year-old talk to a voice clone of 'Rocky' from Project Hail Mary; Wolfram called it 'ElevenLabs V3 for free.'
