Friedrich Faubel (Cerence Inc.): When Speech Enhancement Turned Neural - an Overview of Recent Trends
Date: February 26, 4pm -- Language: English
Abstract: This talk will take you on a journey into the world of speech enhancement, a realm that exists only to separate an acoustic target speech signal from noise, interfering speech or music. While classical approaches were typically quite heavy on the mathematical side, the advent of deep learning radically changed the landscape. It allows for the topic to be formulated as a simple "learning from simulations" paradigm where data generation plays the central role. Starting from an early deep lerning noise reduction approach developed at Ohio State University, we proceed with gradual improvements that finally led to serious products over the last 2 years. The matter will be presented in a vivid fashion. And it will be supplemented with countless examples of how speech enhancement is deployed at Cerence, ranging from improved subjective quality in hands-free telephone calls to facilitating multi-user speech dialog systems such as MBUX (Mercedes Benz User Experience).
