In this paper we describe a new multichannel room impulse responses database. The impulse responses are measured in a room with configurable reverberation level resulting in three different acoustic scenarios with reverberation times RT60 equals to 160 ms, 360 ms and 610 ms. The measurements were carried out in recording sessions of several source positions on a spatial grid (angle range of −90° to...
The authors propose a channel equalization approach to overcome the channel variation in speaker identification over a telephone system. A set of inverse channel spectra is chosen to form a basis for generating the estimated channel equalization filter. When a short utterance goes through the basis filters, the coefficients of a convex combination are produced automatically so that a channel equalization...
