Question

在测试了多种语音转换为文本的方法之后，我最终得出结论，问题出在我的特定设备上，该代码在一个Android 5设备上运行正常，而在其他运行Android 6的设备上却继续收到错误消息

第二个设备是使用自定义sdk的中文设备，我想知道是否有Android本身需要的特定服务才能启用语音识别器，因为我确实安装了Google语音应用并确实使用adb和同一个问题不断出现

有没有一种方法或调试策略可以用来查找此问题的根源。

是的，对“ Google”应用（其ID为com.google.android.googlequicksearchbox）存在依赖性：
您可以检查设备是否已安装，如果没有，请从Google的Play商店中安装。

有没有一种方法或调试策略可以用来查找此问题的根源？

LogCat输出中是否没有错误消息？
