Description: 提交一段录制语音，录音内容 : 数字0~9 和 本人姓名。格式为单声道、16KHz 采样、
16Bits 的线性PCM 数据。录音要求发音平稳，匀速，音量适中（最大幅度要超过3000）。录
音数据按照WAVE 文件格式存放。文件名由和姓名组成: 学号_姓名.wav
1）编写程序(MathLab)，读出所录制的数据。统计文件信号的直流分量，消除直流后显示波
形。
2）编写程序（MathLab）以100 帧/秒的频度（即帧移10mS），分析并显示录音文件的短时
过零率及短时能量，分析帧长20mS。
3）在根据短时能量和过零率曲线，波形图上分别标出10 个数字及姓名语音的起始和结束位
