Abstract
In a speech recognition and control apparatus, the speech signal is filtered into sub-bands, each sub-band signal sampled and binary quantized to form a digital string which is simplified (data reduced or compressed) by further encoding based on detecting in the string an isolated sample having one binary value surrounded by two samples having the other binary value.
