So far I have a Mac and an iPhone. Reading Hebrew with Mac seems to be the worst bet. Unless the authors specifically tag the passages with Hebrew language code, VoiceOver will read the text as letters (in English), or in some cases, it won't read it at all.
iOS seems to have a better language detection performance, but I have doubt that VoiceOver is pronouncing the words incorrectly.
My research for finding a Hebrew TTS for Mac OS and / or iOS that would replace Carmit yielded no outcome.
Unless you guys lead me to a better solution, I think I'll stick with my iPhone to study Ancient Hebrew.
Thank you very much in advance.
