Abstract
A real-time digital spectrum analyser to be used for speech recognition is described. The analyser implements 128 2nd-order digital filters designed using the bilinear transformation. Enough filter coefficients for eight filter banks can be stored in the analyser at any time and the time over which the spectra are averaged is variable. The analyser therefore makes it possible to vary and optimise the front-end processing for speech recognition algorithms.
