Abstract
Dialogue Enhancement (DE) is one of the most promising applications of user interactivity enabled by object-based audio broadcasting. DE allows personalization of the relative level of dialogue for intelligibility or aesthetic reasons. This paper discusses the implementation of DE in object-based audio transport with MPEG-H, with a special focus on source separation methods enabling DE also for legacy content without original objects available. The user-benefit of DE is assessed using the Adjustment/Satisfaction Test methodology. The test results demonstrate the need for an individually adjustable dialogue level because of highly-varying personal preferences. The test also investigates the subjective quality penalty from using source separation for obtaining the objects. The results show that even an imperfect separation result can successfully enable DE leading to increased end-user satisfaction.
