The objective of this paper is to summarize relevant aspects of concept, design, and test of a considerably improved digital radio. The system enables users to request particular information from a set of spoken content and transmitted data services received by Digital Audio Broadcasting (DAB). The core of the solution is a search engine which is able to monitor multiple audio and data services simultaneously. The usage of several information sources, the retrieval process, the concept of the bimodal interface, and the conversational dialog are described with first results of the evaluation at the experimental stage. Hereby the DAB system turns from a classic only-audio receiver into a more enhanced multimedia platform as a part in symbiotic embedded systems such as multifunctional cell phones and sophisticated car entertainment systems. That way, radio can overcome its restrictions in content, presentation format and time and will be able to offer more comprehensive and contemporary choices. We show that a sophisticated radio may offer similar favorable characteristics referred to speech content like internet services do for text.
