The legacy-STRAIGHT is a collection of speech analysis, modification and resynthesis tools.

Set MATLAB path to "src" directory.

Paste the following code to MATLAB command window. It generates copy-synthesized output to the variable "syntheszed_signal".

[x, fs] = audioread('vaiueo2d.wav'); 
f0raw = MulticueF0v14(x,fs); 
ap = exstraightAPind(x,fs,f0raw);
n3sgram=exstraightspec(x,f0raw,fs);
syntheszed_signal = exstraightsynth(f0raw,n3sgram,ap,fs);

For running this using GNU Octave, please load signal package.

pkg load signal
