Latest Patents

Yangqian Wang holds a patent for a "Federated speaker verification method based on differential privacy." This innovative method includes several key steps: first, a server performs UBM pre-training to obtain an initial UBM. Next, the client receives the pre-trained initial UBM and conducts initial UBM learning based on local private speech data. The client then applies differential privacy protection based on learned statistics. Following this, the server aggregates statistics uploaded by multiple clients and updates the initial UBM. Finally, the client receives the updated UBM and performs adjustments based on local private speech data to obtain a GMM for the user, determining whether a to-be-verified speech is generated by the user.
