Kazakh Speech Corpus

The Kazakh speech corpus (KSC) contains around 335 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. The KSC database is available for public and commercial use upon request under Creative Commons Attribution 4.0 International License.
