The '''PCVC (Persian Consonant Vowel Combination) Speech Dataset''' is a [[Modern Persian]] [[speech corpus]] for [[speech recognition]] and also [[speaker recognition]]. The dataset contains sound samples of [[Modern Persian]] combination of [[vowel]] and [[consonant]] phonemes from different speakers. Every sound sample contains just one consonant and one vowel So it is somehow labeled in phoneme level. This dataset containsconsists of 23 Persian consonants and 6 vowels. The sound samples are all possible combinations of vowels and consonants (138 samples for each speaker). The sample rate of all speech samples is 48000 which means there are 48000 sound samples in every 1 second. Every sound sample isstarts 276with seconds(138consonant twothen secondscontinues samples)with vowel. In each 2s sample, in average, 0.5 second of each sample is speech and the rest is silence. In eachEach sound sample 0ends with silence.25s<ref>{{Cite ofjournal|last1=Malekzadeh|first1=Saber|last2=Gholizadeh|first2=Mohammad startHossein|last3=Razavi|first3=Seyyed andNaser|title=Persian 0.25sphonemes ofrecognition endusing PPNet|journal=Journal of itSignal isProcessing surelySystems|year=2018|arxiv=1812.08600|doi=10.13140/RG.2.2.34836.96647|s2cid=214612057 }}</ref><ref>Malekzadeh, scilenceS., AlsoGholizadeh, inM.H. eachand 2sRazavi, firstS.N., consonant2018. phonemePersian pronouncedVowel recognition with MFCC and thenANN vowelon isPCVC speech dataset.

==Contents==

The corpus is downloadable from its GitHubKaggle web page, and contains the following:

* .mat data files of sound samples in a 23*6*30000 matrix, in which 23 is number of consonants, 6 is the number of vowels and 30000 is the length of 2s sound sample.
