- 数字的语音识别matlab程序 训练及识别数据太大,少量上传一点,大家可以用COOLEDIT等软件仿照自己制作.(*.wav文件采样率8000,单声道,采样精度16位,16bit Motorola PCM,*.lab文件存的是语音的起止点和语音内容). -Digit speech recognition matlab program too much training and recognition data, a small amount of upload that you can us
audio
- 本实验旨在了解如何将模拟的声音信号转化为数字信号,重点掌握在数字声音四个重要的技术指标:采样速率、量化比特数、声道数和编码方法。-This experiment aimed at understanding how analog voice signal into a digital signal, with a focus in the hands of digital audio technology to four key indicators: the sampling rate, qu
DeWFile
- 本程序用matlab语言编写,可以读取各种采样频率的wav文件,使用小波方法降噪.对撕撕声效果较好-This procedure language with matlab, you can read a variety of sampling frequency of the wav file, the use of wavelet denoising method. Tear tear on better sound
mp3readandmp3write
- mp3read和mp3write是直接写在wavread更换和wavwrite访问MPEG音频MP3文件。其特点包括: -旨在重复wavread完整语法和wavwrite -还支持上的动态下采样和渠道mpg123的合并-文件优化的很长的MP3 -只需要解码的部分-使用popen函数进行编码,以避免大量临时文件(可用时-看到我popenw墨西哥) -试图消除写保护回路的时间序列文件/通过阅读“热身”样本-包括辅助二进制软件包在Linux,Windows,Mac的PPC的,苹果,英特尔,和Mac英特
soundchange
- 对原始语音进行上采样和下采样,分析对比他们的时域图和频谱图。最后对比原始语音、75HZ激励、150HZ激励以及噪声激励下的效果-SOME SIMPLE MANIPULATIONS OF SOUND USING DIGITAL SIGNAL PROCESSING The original sound and its spectrogram Downsampling the waveform downsampling Upsampling the waveform Li
GUI
- 1)选择一个语音信号作为分析对象,或录制一段语音信号; 2)对语音信号进行采样,画出采样前后语音信号的时域波形和频谱图; 3)利用MATLAB中的随机函数产生噪声加入到语音信号中,使语音信号被污染,然后进行频谱分析; 4)设计用于处理该语音信号的数字滤波器,给出滤波器的性能指标,画出滤波器的频率响应; 5)对被噪声污染的语音信号进行滤波,画出滤波前后信号的时域波形和频谱,并对滤波前后的信号进行比较和分析; 6)回放各步骤的语音信号,给出相应处理程序及运行结果分析。-1) Select a voi
