Professor Adam Finkelstein and graduate student Jiaqi Su detail how a new method could improve the listening experience for podcasts, video voice-overs and audio books. The technology uses artificial intelligence (AI) to transform low-quality recordings of human speech into crisp and clear studio-quality tracks. This technology was presented at Celebrate Princeton Innovation 2021, the University's annual showcase of research with the potential to benefit society. The project was funded by the Princeton University Dean for Research Innovation Fund for New Industrial Collaborations and Adobe Research.
