语音识别的小程序，展示了如何通过声卡采集数据，通过dtw算法识别语音，通过并口输出控制指令-small voice recognition procedures, how to display the data acquisition card, dtw voice recognition algorithm, parallel output control directive

一个小程序，通过声卡来采集音频数据，然后计算分贝值-a small procedure for the adoption of sound card to collect audio data, and then calculate the value of decibels

语音采集与处理的第一部分，采集，基于电脑的声卡采集声音数据，这一步个人认为是最重要的-Speech acquisition and processing, collection, based on the computer' s sound card collecting sound data, this step personally think is the most important
