in speech editing i am receiving an error using sound. ??? Error using ==> playsnd Data must have one or two columns. Error in ==> sound at 58 playsnd(y,fs,bits); is there any problem with sound function?

yfirst= y(1:24000);

ysecond=y(24001:48000);

save anjali ysecond yfirst -ascii

load anjali -ascii

t=0:1/fs:length(anjali)/fs-1/fs;

pause(2)

sound(anjali,fs);

I suspect that if you check, you will find that anjali is either 24000 or 48000 columns, possibly with two rows. sound() requires that it be either one or two columns.

If you are trying to use those values as two channels, then you should just be using

anjali = reshape( y(1:48000), 24000, 2 );
sound(anjali, fs);

with none of that save and load.

i want to give 2 second pause between my voices then play back. it is not giving playing back.

[anjali parashar]

how can i change the code so that it can play back my voice?

[Walter Roberson]

How do you input your voice in the first place? How are you setting "y" ?

There is no way to encode a "pause" inside a sound array. You can encode silence, but not a pause. Silence is encoded as 0.

yfirst = y(1:24000);
ysecond = y(24001:48000);
silence = zeros(2 * fs, 1);   %2 seconds
anjali = [yfirst(:); silence(:); ysecond(:)];
sound(anjali, fs);

[y,fs,nbits]=wavread('C:\Users\HP\Desktop\angel_48k_stereo.wav');

sound(y,fs)

t=0:1/fs:length(y)/fs-1/fs;

i want that first i can listen this voice then after silence of 2 seconds i can listen back this voice.

[Walter Roberson]

silence = zeros(2 * fs, size(y,2));   %2 seconds
anjali = [y; silence; y];
sound(anjali, fs);
