  abstract = {In this paper, the design, implementation and testing
                   of a digital microphone array is presented. The array
                   uses digital MEMS microphones which integrate the
                   microphone, amplifier and analogue to digital converter
                   on a single chip in place of the analogue microphones
                   and external audio interfaces currently used. The
                   device has the potential to be smaller, cheaper and
                   more flexible than typical analogue arrays, however the
                   effect on speech recognition performance of using
                   digital microphones is as yet unknown. In order to
                   evaluate the effect, an analogue array and the new
                   digital array are used to simultaneously record test
                   data for a speech recognition experiment. Initial
                   results employing no adaptation show that performance
                   using the digital array is significantly worse (14\%
                   absolute WER) than the analogue device. Subsequent
                   experiments using MLLR and CMLLR channel adaptation
                   reduce this gap, and employing MLLR for both channel
                   and speaker adaptation reduces the difference between
                   the arrays to 4.5\% absolute WER.},
