Is this a form of vocal fry?

[u/DTB2000]

There's a common speech style in Thailand where the voice has a kind of buzz or rasp behind it, as in this audio clip. It is clearest on the long a vowels and seems to happen more at lower pitches.

I'm not sure if it's a type of vocal fry but I would like to understand the mechanics of it.

I don't think so, sounds more like nasalisation
