Title

Clean dialogue loudness measurements based on deep neural networks

Abstract
Loudness normalization based on clean dialogue loudness improves consistency of the dialogue level compared to the loudness of the full program measured at speech or signal activity. Existing loudness metering methods can not estimate clean dialogue loudness from mixture signals comprising speech and background sounds, e.g. music, sound effects or environmental sounds. This paper proposes to train deep neural networks with input signals and target values obtained fromisolated speech and backgrounds to estimate the clean dialogue loudness. Furthermore, the proposed method outputs estimates for loudness levels of background and mixture signal, and Voice Activity Detection. The presented evaluation reports a mean absolute error of 1.5 LU for momentary loudness, 0.5 LU for short-term and 0.27 LU for long-term loudness of the clean dialogue given the mixture signal.
