Clarifications added to the post:
The TCC “o” is a tense /o/
It is my intention to reflect Sino pronunciations in orthography, so you don’t need to learn how special combinations of letters represent a different sound or how <o> would correspond to a non-/o/ or /ɔ/ vowel in order to see the resemblance between the TCC and the Sino pronunciations.
It was also my intention to use a 6-vowel system with the standard a e i o u ə. So I intentionally did not use more than that. “O” is mostly an “A” in Sino pronunciations and thus <o> isn’t often seen in TCC, appearing mostly only before velars.
Mistakes fixed:
*Final consonants are mostly the same as Cantonese finals.
*Note that Mandarin medials do not
