AV9peechSynthesizer问题的iOS9 AVSpeechUtterance率 [英] iOS9 AVSpeechUtterance rate for AVSpeechSynthesizer issue

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
