# CLARIN-PL Polish Studio Corpus

The corpus was created somewhere in 2014-2015 by recording a group of few hundred volunteer speakers reading a few dozen sentences each. The total size of the corpus is ~56 hours.

Due to the manner of recording, the transcription accuracy is very high, but the manner of speech is not spontaneous. This corpus is best compared to something like TIMIT, possibly CommonVoice. 
It is different from CommonVoice in that it is recorded in a controlled environment (studio, all recordings using same microphone) and consistent manner.

The corpus was downloaded from https://mowa.clarin-pl.eu/korpusy/audio.tar.gz (~4.6GB; MD5SUM af583ab72089d089e31d795ea4f8ea4f)

A proof-of-concept ASR system can also be found on https://github.com/danijel3/ClarinStudioKaldi
