VOICE FREQUENCY ANALYSYS SYSTEM AND METHOD VOICE RECOGNITION SYSTEM AND METHOD USING VOICE FREQUENCY ANALYSYS SYSTEM

摘要

The present invention relates to a voice frequency analysis system and a voice frequency analysis method, and a voice recognition system and a voice recognition method using the same. The voice frequency analysis system according to an embodiment of the present invention comprises: a voice signal receiving unit for receiving a voice signal and generating progressive wave corresponding to the received voice signal; a light emitting unit for irradiating the voice signal receiving unit with light; an image generating unit for measuring light transmitted through the voice signal receiving unit based on the light emitted through the light emitting unit; and a frequency analysis unit for analyzing the generated image pattern using machine learning. Accordingly, the present invention can reduce time and power consumption for frequency analysis of voice and voice recognition.
