Recent in speech synthesis—particularly voice cloning technologies capable of accurately reproducing speaker identity—have involving unlocked new opportunities in domains such as entertainment and human-computer interaction. and present our analysis of detection performance under challenging conditions such as telephony and compressed audio transmission. Given the rapid and continuous evolution of media generation techniques, we also introduce our recent methods for detecting previously unseen approaches. This includes leveraging a large-scale speech foundation model, Anti-Deepfake, to enhance detector generalization and developing automatic data selection algorithms to dynamically expand deepfake training datasets, thereby contributing to an automatic framework for adaptive model optimization.
