+
+KsponSpeech is a large-scale spontaneous speech corpus of Korean.
+This corpus contains 969 hours of open-domain dialog utterances,
+spoken by about 2,000 native Korean speakers in a clean environment.
+
+All data were constructed by recording the dialogue of two people
+freely conversing on a variety of topics and manually transcribing the utterances.
+
+The transcription provides a dual transcription consisting of orthography and pronunciation,
+and disfluency tags for spontaneity of speech, such as filler words, repeated words, and word fragments.
+
+The original audio data has a pcm extension.
+During preprocessing, it is converted into a file in the flac extension and saved anew.
+
+KsponSpeech is publicly available on an open data hub site of the Korea government.
+The dataset must be downloaded manually.
