Hello Shahab,

I constantly faced the error "the sound is not clear" when calling "myprosody" function, I caught the error and it mentions the line 285 of the script MLTRNL.praat which is (vectorf#= zero # (int)). The "zero" is an unknown symbol. I also changed it to 0 but it says you would need to give a vector. Can you please take a look at this line?
