摘要

示波器广泛应用于大学物理实验教学中，相较于传统的模拟示波器，数字示波器将输入模拟信号转换为数字信号进行显示。设计了一个新的使用数字示波器进行人声音识别的综合性实验。实验中把压电陶瓷片贴于测试者的喉部靠近声带处，声带的振动转换为电信号后，使用数字示波器解析测试者的声音特征。在此基础上建立了含多个测试者的语音样本数据库，通过对于测试者声音频率的比对实现了对特定测试者的语音识别。该实验拓宽了示波器的实验教学内容，取得了良好的教学效果。

Abstract:

Oscilloscopes are widely used in college physics experiment teaching． Compared with traditional analog oscilloscopes，digital oscilloscopes convert input analog signals into digital signals for display．It designs a new comprehensive experiment for human voice recognition using a digital oscilloscope．In the experiment，the piezoelectric ceramic sheet was attached to the tester’s throat near the vocal cords．After the vibration of the vocal cords was converted into electrical signals，a digital oscilloscope was used to analyze the tester’s sound characteristics．On this basis，a voice sample database containing multiple testers is established，and the voice recognition of a specific tester is realized by comparing the tester’s voice frequency．This experiment broadens the experimental teaching content of oscilloscope and achieves good teaching effect．

Key words: digital oscilloscope piezoelectric ceramics voice frequency voice recognition
