i'm new here, i am doing my university project on speech
recognition, if somebody could tell me how to convert recorded speech sampling? i've already try using resample code from matlab, but the result was that the sound of speech file dosen't sound very nice. the code that i use was shown below: [y,Fs,bit] = wavread('test8k.wav'); Fs_new = 11025; %the new sampling rate [p q] = rat(Fs_new/Fs,0.0001); new_speech = resample(y,p,q); [filename, pathname] = uiputfile('*.wav', 'Save Data to Wave File'); if filename ~= 0 wavwrite(new_speech,Fs_new,[pathname filename]) end clear; |

I am not sure how good a matlab is at changing sampling rate. Mebbe u shd try cooledit on windows...or sox or esps/entropy (commercial) on linux.

Hi, U can try using interpolate function. [y,Fs,bit] = wavread('test8k.wav'); Fs_new = 11025; %the new sampling rate p = rat(Fs_new/Fs); new_speech = interp(y,p); regards, Abhijit --- In , "khaifahaluk" <khaifahaluk@y...> wrote: > i'm new here, i am doing my university project on speech recognition, > if somebody could tell me how to convert recorded speech sampling? > i've already try using resample code from matlab, but the result was > that the sound of speech file dosen't sound very nice. the code that > i use was shown below: > [y,Fs,bit] = wavread('test8k.wav'); > > Fs_new = 11025; %the new sampling rate > [p q] = rat(Fs_new/Fs,0.0001); > new_speech = resample(y,p,q); > [filename, pathname] = uiputfile('*.wav', 'Save Data to Wave File'); > if filename ~= 0 > wavwrite(new_speech,Fs_new,[pathname filename]) > end > clear; |

Hi Khaifahaluk, You can use SoX (Sound eXchange) instead of Matlab. Quite handy software. It's text-base though. Resampling, converting, fading,..., it's all there. Visit this: http://sox.sourceforge.net/ fajar --- In , "khaifahaluk" <khaifahaluk@y...> wrote: > i'm new here, i am doing my university project on speech recognition, > if somebody could tell me how to convert recorded speech sampling? > i've already try using resample code from matlab, but the result was > that the sound of speech file dosen't sound very nice. the code that > i use was shown below: > [y,Fs,bit] = wavread('test8k.wav'); > > Fs_new = 11025; %the new sampling rate > [p q] = rat(Fs_new/Fs,0.0001); > new_speech = resample(y,p,q); > [filename, pathname] = uiputfile('*.wav', 'Save Data to Wave File'); > if filename ~= 0 > wavwrite(new_speech,Fs_new,[pathname filename]) > end > clear; |
