Hume AI Open Sources TADA: 5x Speed, Zero Hallucination TTS That Can Run 700-Second Audio on Mobile Devices

Hume AI opensources the TADA speech generation model, which uses a text-acoustic dual alignment architecture, significantly improving the efficiency and reliability of TTS systems. By achieving 1:1 strict synchronization between text tokens and acoustic representations, it effectively solves the content hallucination problem in traditional LLM-based TTS. The model has been validated through more than a thousand samples and shows excellent performance.
