▎ 摘　　要

NOVELTY - The method involves connecting a voice recognition sensor with a fixed value resistor in series and placed near an oral cavity. A humidity change signal of different word voice air flow is sensed. A voltage signal at two ends of the fixed value resistor is collected as the humidity change signal of the voice air stream with different words. The voice recognition is performed to different words based on the difference in the humidity change signal of different word voice air flow using a voice recognition algorithm. USE - Method for performing voice recognition. ADVANTAGE - The method enables sensing the fast humidity change signal in the voice airflow, utilizing the difference of the humidity change signal of different word voice airflow, and realizing voice recognition to different words. The humidity change signal is not sensitive to the environment noise so that the voice recognition sensor has better anti-noise performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a voice recognition sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the method for performing voice recognition.
