Title: Multichannel Robot Speech Recognition Database: MChRSR,
Abstract: In real human robot interaction (HRI) scenarios, speech recognition
represents a major challenge due to robot noise, background noise and
time-varying acoustic channel. This document describes the procedure used to
obtain the Multichannel Robot Speech Recognition Database (MChRSR). It is
composed of 12 hours of multichannel evaluation data recorded in a real mobile
HRI scenario. This database was recorded with a PR2 robot performing different
translational and azimuthal movements. Accordingly, 16 evaluation sets were
obtained re-recording the clean set of the Aurora 4 database in different
movement conditions.
