I am utilizing macOS and would like to know how to create accurate or alternate pronunciations using AVSpeechSynthesizer.
Is there a guide or document that indicates the unicode symbols that are used or accepted for the IPA notation?
The only method that I've found is to create or obtain pronunciations is through an iPhone.
