问题
I'm using AVSpeechSynthesizer for text to speech on 2 languages. Is there any way to specify speech stress on different part of the word?
I've tried placing ' before and after desired vowel, and also using vowels with stress marks, e.g. ó, ý - which does not seem to have any impact.

In my case (language code is ru-RU), ` char helps to set word stress.
