Improving Short Utterance Anti-Spoofing with AASIST2

2023 · arXiv (Cornell University)

The wav2vec 2.0 and integrated spectro-temporal graph attention network (AASIST) based countermeasure achieves great performance in speech anti-spoofing. However, current spoof speech detection systems have fixed training and evaluation durations, while the performance degrades significantly …

Flexpéro: Flexible Expressive Zero-Shot Speech Refinement via In-Context Learning

2025 · IEEE Signal Processing Letters

Controlling speech expressiveness has emerged as a critical research frontier in speech generation, focusing on synthesizing natural, human-like speech that accurately conveys intended psychological and emotional states. While many large-scale models have demonstrated sufficient zero-shot …
