After many years of narrow-band (300 Hz–3.4 kHz) voice communication history, a strong trend toward higher speech and audio quality for communication has emerged. Driven by the industry, enhanced services and products become available, such as wide band audio for mobile phones, room telepresence systems, and Apple's iPhone/FaceTime mobile videoconferencing. This workshop presents latest research results on the requirements for these applications from the European research project TA2. The underlying key technology is discussed, i.e., new low delay codecs—standardized by MPEG and ITU-T—providing high quality with full audio bandwidth and stereo transmission even at low data rates. Finally, one of the most promising ongoing standardization activities, the 3GPP Enhanced Voice Service (EVS) is presented as an outlook from a technology and service perspective.
