Abstract
In a signal reproducing device for reproducing voice signals from vector-quantized coded data, transferred or recorded coded data is extracted one by one, and the coded data extracted are given as initial values to a recurrence equation to generate a pattern composed of a predetermined number of data for every initial value. The thus generated patterns are sequentially output as reproduction data.
