AVSpeechSynthesizer word stress
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. 回答1: In my case (language code is ru-RU), ` char helps to set word stress. 来源: https://stackoverflow.com/questions/32736130/avspeechsynthesizer-word-stress
