Meituan LongCat Team Unveils LongCat-AudioDiT: A Breakthrough in Zero-Shot TTS Voice Cloning Technology
The Meituan LongCat team has officially released LongCat-AudioDiT, a pioneering model designed to push the boundaries of zero-shot Text-to-Speech (TTS) voice cloning. By fundamentally redesigning the synthesis pipeline, the team has moved away from traditional intermediate representations like Mel-spectrograms. Instead, LongCat-AudioDiT operates directly within the waveform latent space using a diffusion-based architecture. This strategic shift is intended to eliminate the cascade errors typically associated with multi-stage data conversion processes. By allowing the AI to learn the inherent laws of sound directly, the model aims to provide a more seamless and high-fidelity voice cloning experience, representing a significant technical leap in the field of generative audio and speech synthesis.
