This dataset contains speech from Finnish parliament 2008-2020 plenary sessions, segmented and aligned for speech recognition training. In total, the training set has:

1.4 million samples3100 hours of audio460 speakersover 19 million word tokens

Additionally, the upload contains 5h long development and 5h long evaluation sets described in publication 10.21437/Interspeech.2017-1115. Due to the size of the training set (~300 GB) and Zenodo upload limit (50 GB), only the development and evaluation sets are published on Zenodo. Rest of the data is available at: http://urn.fi/urn:nbn:fi:lb-2021051903

The training set comes in two parts:

2008-2016 set which is originally described in publication 10.21437/Interspeech.2017-1115. This set includes a list of samples from sessions in 2008-2014 that can be combined with the 2015-2020 set to form the 3100 hour training set.A new 2015-2020 dataset.

All audio samples are single-channel, 16 kHz and 16-bit wav files. Each wav file has corresponding transcript in a .trn text file. The data is machine-extracted so there still remains small inaccuracies in the training set transcripts and possibly few Swedish samples. Development and evaluation sets have been corrected by hand.
