After a couple of decades of somewhat slow development, voice technologies have once again gained a momentum. Much of this has been driven by large leaps in speech and speaker recognition performance and consequently, the development of many voice interfaces. Some notably successful examples of current applications of voice are the Amazon Echo and Apple Siri but we also see and increasing number of institutions that make use of voice recognition to replace more traditional customer identification methods. While much of this development is exciting for speech and audio processing research, it also creates new and significant challenges in security and privacy. Furthermore, new technologies for various forms of voice modification and synthesis are on the rise which only exacerbates the problem.
In this talk we will first introduce Pindrop and the company’s mission in the world of voice security and we will take a glimpse into the global fraud landscape of call centres, which motivates the work that we do. Next, we will take a deeper dive into the specific topic of voice modification and some related research results. Finally, we will provide an outlook into the future of voice and voice security.
