Paper Abstract

In this paper, a new type of sound-optical array of microvibrator sensor which detect speech features in frequency domain and the fabrication process of the microvibrator is presented. The technique of detection by optical fiber and speech recognition in noise using neural networks (NNs) has been described. The results of experiments show that the sensor based on the new idea is suitable for an optical sensor, especially for the speech recognition system with optic-machinery unitization for it changes the sound signal into an optical signal, at the same time it carries out parallel filters spectrum analysis to obtain directly sound spectrum features which can be used as input of the NNs.
