toki pona has a very simple phonology, so it's phonemes can be pronounced many ways.
When I learn a language I like to try learning the accent. But there's no example of a detailed allophony for toki pona, and strictly speaking with the IPA pronunciation wouldn't be realistic.
So this is my realistic "accent" for toki pona. It doesn't change the phonology, and it doesn't break any rules by collapsing or creating new distinctions. It is similar to Japanese in some ways, but also has it's own sound to it.

They are not distinct phonemes, but a palato-alveolar articulation [ʃ] occurs before /i/, and a slightly retracted alveolar articulation [s̠] occurs before /e, a, o, u/.
Syllable final /n/ becomes /m/ before /p/, like "anpa" [ʔamba], /ŋ/ before /k/, [n] before /t/, /s/, /l/, /w/, /j/ and /ŋ/ at the end of a word.
The semivowels /i/ and /u/ become vowel sequences following /n/, like "linja" /ɺinia/.
Plosives are voiceless at the beginning of words, voiced and unaspirated elsewhere.
A glottal stop presets any word beginning in a vowel, similarly to Hausa, German, and Singapore English. This also occurs in other English dialects, as well as the majority of languages, but not as regularly.
