       abstract = {Learning speaker turn embeddings has shown considerable improvement in situations where conventional
speaker modeling approaches fail. However, this improvement is relatively limited when compared to the gain observed in face embedding learning, which has proven very successful for face verification and clustering tasks. Assuming that face and voices from the same identities share some latent properties (like age, gender, ethnicity), we propose two transfer learning approaches to leverage the knowledge from the face domain learned from thousands of identities for tasks in the speaker domain. These approaches, namely target embedding transfer and clustering structure transfer, utilize the structure of the source face embedding space at different granularities to regularize the target speaker turn embedding space as optimizing terms. Our methods are evaluated on two public broadcast corpora
and yield promising advances over competitive baselines in verification and audio clustering tasks, especially when dealing with short speaker utterances. The analysis gives insight into characteristics of the embedding spaces and shows their potential applications.},
