Answer 1

尝试将其添加到AndroidManifest.xml：

<queries>
        <intent>
            <action android:name="android.speech.RecognitionService" />
        </intent>
    </queries>

Answer 2

在我的情况下，我通过删除extair_speech_input .. 组件的语音修复了此问题。启动语音识别时传递的参数。

将我的代码从中更改

  Voice.start('en-US', {
    EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS: 5000,
    EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS: 5000,
    EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS: 5000,
  });

为此

 Voice.start('en-US')

Answer 3

好吧，我不知道这是否对您有用，但是就我而言，我已经在AndroidManifest中添加了它：

 <package android:name="com.google.android.googlequicksearchbox"/>
