Abstract
The necessity of dereverberation algorithms in hand-held speech communication systems is discussed in this contribution. The study is based on a new measurement campaign with artificial head and a two-microphone mock-up phone in realistic acoustical environments like an office, corridor and stairway. Based on objective speech quality measures as well as a listening test, we show that room reverberation can lead to a decrease in intelligibility even for hand-held telephony under certain conditions. Hence, the far-end listener can benefit from dereverberation algorithms in the sending device. All measured room impulse responses are available online as part of the Aachen Impulse Response (AIR) database.Download
