The recent developments in the research area focus on enhancing the capabilities of speech synthesis, voice detection, and conversion, as well as improving the generalization and robustness of models across various domains and datasets. Innovations include the adaptation of multi-modal self-supervised models for text prediction from real-time MRI, the introduction of disentanglement frameworks for domain-agnostic artifact features in AI-synthesized voice detection, and the development of speaker-adaptive TTS frameworks that leverage prosody prompting for stable synthesis. Additionally, there's a significant push towards improving model generalization in low-resource scenarios, such as human activity recognition and respiratory sound classification, through novel data augmentation techniques and transformer-based contrastive meta-learning approaches. The field is also seeing advancements in multi-band massive MIMO transmission with the extrapolation of channel fingerprints using cycle-consistent generative networks, and the generation of synthetic radio-frequency data for data augmentation. Lastly, robust COVID-19 detection from cough sounds using deep neural decision trees and forests highlights the potential of machine learning in medical diagnostics.
