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 consists 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 starts with consonant then continues with vowel. In each sample, in average, 0.5 second of each sample is speech and the rest is silence. Each sound sample ends with silence.<ref>{{Cite journal|last=Malekzadeh|first=Saber|last2=Gholizadeh|first2=Mohammad Hossein|last3=Razavi|first3=Seyyed Naser|title=Persian phonemes recognition using PPNet|journal=Journal of Signal Processing Systems|year=2018|volume=|pages=|arxiv=1812.08600|doi=10.13140/RG.2.2.34836.96647}}</ref><ref>Malekzadeh, S., Gholizadeh, M.H. and Razavi, S.N., 2018.
