Discussion
I think Miekko made the point on his blog (when I borrow I'll make mention wherever as possible) that there is limited use for the specification of phones and phonemes in a conlang. If I understand, then what remains are underspecified. Therefore I am coining a new word by analogy.

dialect:diaphonemes
idiolect:idiophonemes

English dialects have different phonological and often phonemic representations for their vowels. This will likely be true for people coming from different backgrounds, as in Esperanto. I see no reason to harp on pronunciation so I'm sorry to disappoint but there will likely be no phonological interpretation/discussion for this language.

Stress may or may not be an idiolectical phenomenon.

Vowels
<a e i o u>
/A~O E~{ i~I @ u/
Note: It's entirely acceptable to have a cardinal pronunciation.

Diphthongs & Odd Syllables
<ai ei oi eo uo ou au iu>
/ai ei @i E@ u@ @u Au iw/
Note: this list is not exhaustive. Other vowel combinations are rare and tend to break into two or more syllables.

Consonants
<p t c j k s f x z h m n l r y w>
/p t t_s t_S k s f S T x m n l r~4~r\~R~X j w/
