I suppose that "abjad" and "abugida" are Arabic and Amharic, respectively,
and AFAIK the pronunciations you have shown match the original languages.

I guess that these tiny adaptations are normal with any foreign term in any
language. You probably also realize the "i" and "u" in "abugida" as [ɪ] and
[ʊ], and the unstressed "a" as [ə].

As an Italian, I of course cast the sounds in my own language's phonemes:
[ˈɑbʤɑd̪] and [ɑbuˈgiːd̪ɑ].
