Android语音识别API在Android 7 Nougat中不起作用

Question

我正在使用android.speech.SpeechRecognizer API进行语音处理.

我在Android 4-5中工作得很好,

在Android 6中它现在有一堆错误,比如当麦克风打开时发生的响铃被检测为语音,所以它存在(并且当它重新启动时无限循环,因为检测到语音,我们有一个黑客解决方法,为此在播放铃声之前将音量设置为0 ...)

在Android 6中,演讲也会在5秒后死亡,没有任何错误或任何错误.我们有另一个黑客解决方法,它可以检测到没有活动5秒并重新启动它...

现在在Android 7中,语音识别似乎根本不起作用？我还没有能够调试为什么,但有没有人在Android 7中使用语音API的问题？

此外,如果有人知道为什么Android似乎在每个版本的语音API中添加新的错误而不修复它们,请回复.这是Android应该支持的内容,还是他们希望您使用Google意图？

我的代码在 Nexus5x(Nougat) 和 Nexus9(Nougat) 上运行良好
