Abstract
A speech recognition system for recognizing the remote-controlling vocal commands of TV sets and VCRs comprises a microphone for receiving the speech pronounced by a user; a speech analyzer for analyzing the speech input via the microphone; circuitry for detecting a vocal section of the speech from the speech analyzer and performing a time-axis normalization and a binarization for the detected vocal section; and a multilayer neural network for receiving the binarization data from the aforementioned circuitry and then performing the learning, to thereby output the speech recognition result. Accordingly, the present invention can enhance the recognition ratio of speech.
