Page Under Construction: Automatic Transcription of Phonemic and Phonetic Portuguese
by David Kenneth Crandall, © 2024

Disclaimer: This app is not able to distinguish consistently between stressed closed and open /e/ and /o/ when not marked as "ê" and "é", or "ô" and "ó", as this may require grammatical parsing
to disambiguate homographs, or other information which this app does not have. Such phonemes not disambiguated by this app will be displayed as "É/Ê" and as "Ó/Ô", but I have tried to make
it distinguish these sounds as much as I reasonably can by using word lists with hundreds of
words with these distinctions.                  
                                    


Optional Regular Expression:

[] → []

/   {}_
    _{}
     {}_{}

Example to aspirate ɾ before n or l:
[ɾ] → [ɦ]
/ _{[nl]}
