Researchers have developed Alignment-Free Text-Audiobox (Text-AB), a novel framework for voice dubbing and dialogue synthesis. This system utilizes a Diffusion Transformer with a flow-matching objective and operates on latent diffusion with DAC-VAE features, achieving higher compression and improved resynthesis quality compared to previous methods. Text-AB is alignment-free, learning text-speech alignment through cross-attention without explicit duration prediction. A large-scale 3B-parameter model was pre-trained on 480k hours of speech and fine-tuned for various tasks, demonstrating significant improvements in prosody, voice similarity, naturalness, and human-likeness for both dubbing and dialogue synthesis.
