@sinbach Didn't know much about Bhutan, I downloaded a prayer guide for Buddhist peoples from the Joshua Project
https://www.joshuaproject.net/assets/media/prayer/guides/prayer-guide-buddhism.pdf
They list 40 people groups and more than a dozen languages. Maybe more than one recording is needed?
From Wikipedia: In Bhutan's education system, English is the medium of instruction, [surprised me; I wonder if young people would want Bible audio in English in part for language study?] while Dzongkha is taught as the national language. Ethnologue lists 24 languages currently spoken in Bhutan.
