The Pansori TEDxKR Corpus is a Korean speech recognition (ASR) corpus generated from Korean language TEDx talks given in Korea from 2010 to 2014. It contains about 3 hours of speech audio-transcript pairs from 41 speakers.

This corpus was generated by using a new corpus data ingestion and processing system called Pansori. Please refer to <a href="https://github.com/yc9701/pansori">this code repository</a> and the following paper for further information on the Pansori ASR corpus generation system:

Extra care was taken to maintain the quality of the generated corpus:

<ul>
  <li>Only TEDx talks hand transcribed by community translators were included.</li>
  <li>Corpus fragments were segmented at subtitle boundaries.</li>
  <li>Fine tuning segmentation by manual (tool-assisted) speech-text alignment.</li>
  <li>Final validation by state-of-the-art speech recognizer (<a href="https://cloud.google.com/speech-to-text/">Google Cloud Speech-To-Text</a>).</li>
</ul>

The speech audio included in the corpus are 16 bit FLAC files with sampling rate of 16 KHz.
