This dataset is the first phoneme based speech dataset in the entire world and also the first free Persian speech dataset to help Persian speech researchers. It is not only what you see. It is growing. To be continued...
What it is
This dataset contains of 23 Persian consonants and 6 vowels. The sound samples are all possible combinations of vowels and consonants (138 samples for each speaker) with a length of 30000 data samples. The sample rate of all speech samples is 48000 which means there are 48000 sound samples in every 1 second. In each sample, sound starts with consonant and then there is a vowel sound and at last there is silent. length of silence is dependent on length of combination of consonant and vowel. For example if combination ends in 20000th data sample, so the rest of 10000 sample (untill 30000, the length of each sound sample) are silence.
All of sound samples are denoised with "Adaptive noise reduction" algorithm.

How to use
Each files contains just a matrix "x".
The sign "_N" (N as number) in "Samples" directory (Like in Sample "S0001_2.mat") means this sample is the Nth sample from the speaker of "S0001.mat".
All files are ".mat" files. ".mat" is a fromat for data files in Matlab. Every file consists of a matrix with dimensions 1236*30000 in which 23 is refer to number of consonant, 6 is refer to number of vowel and 30000 is the length of sound sample. order of phonemes are just like shown in Here. To use it, just open the file and tap on "finish" button to import the data in workspace of Matlab.
To use ".mat" data files in Python you can use the code below to copy the matrix in the file in "aud" variable (Put your current path instead of "MyPath"). Every file consists of a matrix with dimensions 1236*30000 in which 23 is refer to number of consonant, 6 is refer to number of vowel and 30000 is the length of sound sample. order of phonemes are just like shown in Here.
# For example for S1 sample (Reading from source and writing it as "Speaker1.mat" in your current directory): import urllib.request as urllib2 matfile = urllib2.urlopen("https://raw.githubusercontent.com/S-Malek/PCVC/master/Samples/S0001.mat") with open('Speaker1.mat','wb') as output: output.write(matfile.read())
# Reading it from current directory and putting the matrix of it in "aud" variable import scipy.io mat = scipy.io.loadmat('Speaker1.mat') aud=(mat['x'])
