Description: 观测实时模拟信号（语音）的频谱
用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图。
-Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of voice, voice saved as. Wav format. Wav file of the sub-Fourier transform analysis to make. Speech is divided into syllables, it should be sub-analysis, and practical application of digital signal processing of the FFT points is limited, generally only reach 1000 points. Fourier inverse transform IFFT, to restore the signal from the frequency domain. Draw the spectrum map and voice waveform.

Description: 这是一个matlab程序，该程序的功能是读取一个 .wav 格式的语音信号，画出该语音信号的短时能量。主程序调用了自己编写的两个函数，函数的功能分别是对语音信号进行分帧以及计算每一帧的时间。语音分帧是语音信号处理的关键步骤，该程序可以帮助你快速入门。-This is a matlab program, the function of the program is to read a ' .wav' voice signal format, draw short-term energy of the speech signal. The main program calls two functions I have written, performance function are calculated for each sub-frame and the time frame of the speech signal. Voice Framing is a key step in the speech signal processing, the program can help you get started quickly.
