问题描述

我使用 AVSpeechSynthesizer 和 AVSpeechUtterance 进行文本到语音转换.它工作正常，但用户必须在其设备的辅助功能设置中启用 SpeakSelection 功能.有没有办法为他们做，或者至少检查设置并警告他们?

I use AVSpeechSynthesizer and AVSpeechUtterance for text-to-speech. It works fine, but the User must enable SpeakSelection feature in his/her device's accessibility settings. Is there a way to do it for them, or at least check the settings and warn them?

推荐答案

也许你可以试着说点什么，附上代表并测量说话的持续时间.如果说出你的文字的持续时间接近于零，用户应该检查设置/下载语音左右！

Maybe you can try to say something, attach delegate and measure duration of speaking. If duration of speaking out yours text is near zero, user should check settings/download voice or so!
