Tech Papers 2019: This paper evaluates how voice-controlled digital assistants impact radio services, presenting a prototype that offers personalized audio features and assessing user interaction with flexible voice-driven radio access.
Abstract
The paper evaluates the impact of voice-controlled digital assistants on the evolution of radio services, proposing to apply radio personalization, recommendation and content atomization techniques to the conversational interface. The paper introduces the relevance of smart speakers for radio, and then technically describes a prototype based on voice-controlled digital assistants providing a set of personalized audio services, like keyword-based Audio-On-Demand (AoD) search, semantic similarity search and content-based audio recommendations. A first analysis of the impact of semantically coherent audio segments with metadata, or audio atoms, is also included, leveraging on a subset of the available AoD archive.
