ISSAI Kazakh Speech Corpus v1.1

The version 1.1 of Kazakh speech corpus (KSC). Different from the previous version 1.0, the corrupted utterances have been removed from the training, validation and test sets. The KSC version 1.1 contains around 332 hours of transcribed audio comprising over 154,000 utterances spoken by participants from different regions, age groups, and gender. It was carefully inspected by native Kazakh speakers to ensure high quality. The KSC is the largest publicly available database developed to advance various Kazakh speech and language processing applications such as speech recognition, speech synthesis, and speaker recognition.
