问题描述
对于iOS 9和早期版本的操作系统，AVSpeechUtterance率不起作用。
这是我必须做出的改变，以便以相同的速度说出句子。我需要为iOS9做出任何其他更改吗？
似乎将AVSpeechUtterance.rate乘以6.0可以正常工作。
谢谢！
The AVSpeechUtterance rate does not work the same for iOS 9 and prior versions of OS.Which is the change I have to make so that the sentence is spoken at the same speed. Are there any other changes I need to make for iOS9?It seems that multiplying the AVSpeechUtterance.rate by 6.0 works fine.Thank you!
推荐答案
我在使用新的XCode编译后也看到了这一变化。以下是我从旧到新速度的映射。如果设备是< = iOS8或> = iOS9，我现在有不同的速度分配。
I also see the change after compiling with the new XCode. Below are my mappings from old to new speed. I now have different speed assignments if device is <= iOS8 or >= iOS9.
iOS 8 iOS 9
Very Slow 0 0.42
Slower 0.06 0.5
My Normal 0.15 0.53
Faster 0.23 0.56
