iOS 中有内置的语音识别开发工具吗？
我如何检测语音是从某些音频文件开始的。我只需要检测语音的开始和停止而不进行识别 谢谢。
How can I detect that speech was started from some audio file. I need only detect start and stop of the speech without recognition
Thank you.

看看这个应用程序

您可以稍微修改此示例代码以获得您需要的内容...

Check out this app

您可以使用音调检测器来监听人类语音范围内是否存在谐波音调。不过我不知道有什么适用于 iOS 的音高检测器。我自己写的，这非常困难。
Dirac 进行音调检测，我不知道它有多准确，因为我不想花 1000 英镑购买许可证。
You could use a pitch detector to listen for the presence of harmonic tones within the range of human speech. I don't know of any pitch detector for iOS though. I wrote my own And it was very hard.
Dirac does pitch detection, I don't know how accurate it is because I don't want to spend £1000 on the licence.
