+This dataset combined [google/fleurs](https://huggingface.co/datasets/google/fleurs), [openslr/openslr42](https://huggingface.co/datasets/openslr/openslr), and cleaned [seanghay/khmer_mpwt_speech](https://huggingface.co/datasets/seanghay/khmer_mpwt_speech).
+Severals processes are executed:
+1. clean up [seanghay/khmer_mpwt_speech](): manually correct wrong transcriptions over 2058 rows
+2. normalize transcription: remove invisible white space; process `ៗ`, numbers, currencies, date into khmer text; and separate each word by space
+3. filter out texts whose number of token ids are more than 448: use tokenizer of Whisper-Small to encode text and filter out sequences longer than 448
+4. filter out audio with length longer than 30 seconds
+5. resample audio to 16000kHz
+
+__Disclaimer__ I do not own any of these datasets.
