Abstract

With a continuously increasing desire for natural and comfortable human/machine interaction, the acoustic interface of any terminal for multimedia or telecommunication services is challenged to allow seamless and hands-free audio communication in such diverse acoustic environments as passenger cabins of cars or office and home environments. Typical applications include audio- /video-conferencing, dialog systems, computer games, command-and-control interfaces, dictation systems, or high-quality audio recordings. Compared to speech and audio capture using a microphone next to the desired source, seamless audio interfaces cause the desired source signal to be impaired by reverberation due to reflective acoustic environments, local interference and noise, and acoustic echoes from loudspeakers. All these interferers are not only annoying to human listeners but, more importantly, they are detrimental for example when speech recognition is involved.
