TEDxSK and JumpSK: A New Slovak Speech Recognition Dedicated Corpus

Abstract

This paper describes a new Slovak speech recognition dedicated corpus built from TEDx talks and Jump Slovakia lectures. The proposed speech database consists of 220 talks and lectures in total duration of about 58 hours. Annotated speech database was generated automatically in an unsupervised manner by using acoustic speech segmentation based on principal component analysis and automatic speech transcription using two complementary speech recognition systems. The evaluation data consisting of 50 manually annotated talks and lectures in total duration of about 12 hours, has been created for evaluation of the quality of Slovak speech recognition. By unsupervised automatic annotation of TEDx talks and Jump Slovakia lectures we have obtained 21.26% of new speech segments with approximately 9.44% word error rate, suitable for retraining or adaptation of acoustic models trained beforehand.

UCSY-SC1: A Myanmar speech corpus for automatic speech recognition

“…Today, the internet has various resource types, for example, social media, blogs, twitter, and new portals, which offer a lot of speech data and which can be freely downloaded. Moreover, it has been proved that the corpora created on internet resources yielded promising results [8] [9]. Therefore, speech data was collected first from the web news.…”
