Modeling, Scaling, and Decoding: Optimizing Controllable Speech Generation with Nonverbal Vocalizations

An NVV-aware DiTAR system that models continuous speech latents, encodes the 16 target NVV categories as dedicated to- kens, and adapts stop prediction to distinguish mid-utterance vocalizations from utterance boundaries is developed.

DiTAR+: Dual Optimization for Robust Autoregressive Diffusion Speech Synthesis

The proposed DiTAR+, a dual-optimization framework for continuous-latent Autoregressive Diffusion Transformer models, introduces Dilated Context Sampling and Hierarchical Acoustic Masking to prevent shallow layers from attending to acoustic pre-context, explicitly decoupling semantic alignment from acoustic detail reco...
