我正在测试VoiceRecognition.i已经搜索过,但没有找到任何可行的答案。 这是代码。
import android.content.Intent;

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());
speechRecognizer.setRecognitionListener(this);
button.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
private static final int SPEECH_REQUEST_CODE = 0;
// Create an intent that can start the Speech Recognizer activity
private void displaySpeechRecognizer() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
this.getPackageName());
speechRecognizer.startListening(intent);
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) {
List<String> results = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
String spokenText = results.get(0);
System.out.println(spokenText);
// Do something with spokenText
}
super.onActivityResult(requestCode, resultCode, data);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.

return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button:
displaySpeechRecognizer();
break;
}
}
@Override
public void onReadyForSpeech(Bundle params) {
System.out.println("onReadyForSpeech");
}
@Override
public void onBeginningOfSpeech() {
System.out.println("onBeginningOfSpeech");
}
@Override
public void onRmsChanged(float rmsdB) {
System.out.println("onRmsChanged");
}
@Override
public void onBufferReceived(byte[] buffer) {
System.out.println("onBufferReceived");
}
@Override
public void onEndOfSpeech() {
System.out.println("onEndOfSpeech");
}
@Override
public void onError(int error) {
System.out.println("onError");
}
@Override
public void onResults(Bundle results) {
System.out.println("onResults");
}
@Override
public void onPartialResults(Bundle partialResults) {
System.out.println("onPartialResults");
}
@Override
public void onEvent(int eventType, Bundle params) {
System.out.println("onEvent");
}
}
这就是布局。

android:text="whats up"

我收到此错误 - &GT; &#34;语音识别E / SpeechRecognizer:绑定到识别服务失败&#34; 也找不到任何有用的例子。

我刚遇到同样的问题,对我来说,问题是我的手机上安装了Cyanogenmod版本,但没有安装语音搜索。以下是我解决问题的步骤:
adb devices
确保它可以与您的设备通信如果您的设备未列出,则需要确保手机的USB驱动程序正确无误。adb root
adb shell
cat /proc/mounts
。您正在寻找类似/dev/block/mtdblock4 /system yaffs2 ro, realtime 0 0
。mount -o rw,remount /dev/block/mtdblock4
。使用命令exit
adb push C:\VoiceSearch.apk system/app
adb shell
返回到adb shell,然后使用mount -o ro,remount /dev/block/mtdblock4
以只读模式重新安装存储(为了安全起见,您可以将其保留在外),然后退出shell 那就是它。无需重启。您可以通过定期Google搜索并按下麦克风按钮来查看是否启动来测试。

如果您在模拟器中运行,则它没有语音识别功能。
答案 2 :(得分:0)
将语音输入设置中的“增强型Google服务”(请参见屏幕截图)更改为基本:
答案 3 :(得分:0)
有时,语音识别仅在较旧的设备上不可用。 检查this condition是否有“系统上有语音识别服务”。
答案 4 :(得分:0)
从 API 级别 30 需要为 android.speech.RecognitionService
添加 <queries>
到 AndroidManifest.xml
<queries>
<intent>
<action android:name="android.speech.RecognitionService" />
</intent>
</queries>
