Speech characteristic signal recognition is an important aspect in the field of speech recognition research, generally USES pattern matching the original understanding Definitely. Operation process of speech recognition are as follows: first, after waiting for voice recognition into electrical signal input and recognition system, after pretreatment Mathematical method was used to extract speech signal, and extracts the phonetic characteristics of signals can be as the segment of speech patterns. And then the Audio model compared to a known reference model, get the best match the reference pattern for this speech recognition results.
