Mission
Contributing to Society Through Acoustic Research
and State-of-the-Art Technology
Our laboratory is committed to its mission to resolve complex sound-related issues affecting Japanese society through academic research and advanced acoustic technologies. We continuously endeavor to contribute to society, pioneering efforts to tackle issues that cannot be addressed by conventional speech information processing and develop scientific and technological solutions to address them. Some of the problems we have focused on include deep fakes, voice cloning, and privacy implications associated with large-scale speech data used to train generative models. We also provide support for Japanese university research by publishing research data sets and organizing academic challenges as an Inter-University Research Institutional Corporation.

- Q.01 What are the advantages of studying for a Ph.D. at NII's Yamagishi Lab?

Reaping the Benefits from the Extensive Research Supervision and Professional Career Development:
The Ph.D. Experience at Yamagishi Lab I enjoyed the benefits of receiving extensive research supervision and career development opportunities provided to me at Yamagishi Lab. I participated in the Lab's Ph.D. program as a working student and as a transfer student from a different academic discipline. Since I had initially been studying geochemistry in my undergraduate and graduate research fields, and worked as a web system programmer, I had no prior background in speech information processing research. Despite this, I was able to complete my Ph.D and begin my career as a researcher largely owing to the invaluable support I received from Yamagishi Lab.
I found that attending summer schools and conferences, research supervision through the mentor system, the presence of highly motivated research team members, and curriculum and graduation requirements compatible with my work all contributed immensely to my experience. I had been considering university Ph.D. programs before entering NII's. After graduating, I worked as a faculty member at a university, supervising Ph.D. students. Drawing from this experience, I feel that the Ph.D. program at NII has a more robust and supportive supervision system than that of universities. While my research during my studies focused predominantly on spontaneous bottom-up research based on my chosen research topics, I also got involved in top-down research and social implementation initiatives led by some post-doctoral fellows. It wasn't apparent to me then, but these top-down research and social implementation initiatives were far more strategic than I had expected, and my involvement in them has been instrumental in advancing my career since then. I strongly recommend Yamagishi Lab's Ph.D. program for those aspiring to make the leap from a similar situation.
- Q.02 I'm interested in the social application of research findings; can I work as an AI engineer or programmer at NII's Yamagishi Lab?
-
Do you want to participate in projects implementing cutting-edge AI research results into social applications? Yamagishi Lab is looking for AI engineers and programmers. Implementing research findings in social applications requires the efforts of researchers as well as AI engineers and programmers. Yamagishi Lab has given a high priority to the implementation of its research findings into social applications in line with increasing demands. With several AI engineers and programmers working on our implementation projects, our laboratory has successfully brought multiple initiatives to fruition. Social implementation projects in the Yamagishi Lab are characterized by the unique structure of having a social implementation team working in parallel with a research team. Dr. Yamagishi oversees both teams while a researcher is assigned to bridge the gap between them. I use my experience in industry and academia to work on both teams and bridge the gap between them. We are looking for AI engineers and programmers to join our team in developing and delivering cutting-edge results.
