CIS Seminar: “Recovering, manipulating and enhancing recorded speech (1905-2020)”
September 15, 2020 at 3:00 PM - 4:00 PM
This talk will survey several recent projects dealing with recorded speech. The first explores an optical process for recovering sound recorded onto postcards using a forgotten technology from more than a century ago. This involves scanning the postcard at multiple orientations using a flatbed scanner, and then reconstructing the fine scale surface texture of the card (where the audio is encoded) using photometric stereo, a technique from computer vision. We will then discuss more modern applications as well, including a text-based interface for editing recorded audio narration that is capable of synthesizing new words matching the voice of the narrator. Finally, given that real-world audio recordings are often degraded by factors such as noise, reverberation, and equalization distortion, we will also introduce a deep learning method to transform recorded speech to sound as though it had been recorded in a studio.
