TEDxSK and JumpSK Lecture Speech Corpus

TEDxSK and JumpSK is a new Slovak spoken language resource built from TEDx and Jump Slovensko lectures. The presented speech corpus consists of 220 lectures in total duration of 58 hours. Annotated speech corpus was generated automatically, in an unsupervised manner, by using acoustic speech segmentation based on a principal component analysis and automatic speech transcription using two complementary speech recognition systems. For evaluation of quality of automatic transcription of speech, an evaluation set composed of 50 lectures, in total duration of 12 hours with manual transcription, has been created.
