The Online Indonesian Learning (OIL) dataset or corpus currently contains lessons from three Indonesian teachers who have posted content on YouTube.

Please see Zara Maxwell-Smith and Ben Foley, (forthcoming), Automated speech recognition of Indonesian-English language lessons on
YouTube using transfer learning, Field Matters Workshop, EACL 2023


To stream the videos of these teachers please visit:
Indonesian Language for Beginners - https://www.youtube.com/@learningindonesianlanguage3334
5-Minute Indonesian - https://www.youtube.com/@5-minuteindonesian534/featured
Dua Budaya - https://www.youtube.com/@DuaBudaya/about

Copies of some lessons on these channels are available as part of this dataset in mp4 and wav formats.
A select number of lessons have matching ELAN files with human and human/machine generated orthographic transcriptions of the audio, as well 'tiers' with machine inference only. 
Detailed information about the audio quality, remarks on background noise, code-switching behaviour and lesson content is available in the paper above.

Almost all videos contain a mix of languages, with some dominated by Indonesian or English.
Some videos explicitly focused on variation in Indonesian or words from other languages which are commonly mixed into Indonesian by speakers.
