android语音转文字

Android平台上可以使用Google提供的语音识别API来实现语音转文字的功能。具体步骤如下:
1. 在AndroidManifest.xml文件中添加以下权限:
```
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
```
2. 在build.gradle文件中添加Google提供的语音识别API依赖:
```
dependencies {
implementation 'com.google.android.gms:play-services-speech:11.0.4'
}
```
3. 在代码中使用SpeechRecognizer类实现语音转文字功能,示例代码如下:
```
private void startSpeechToText() {
SpeechRecognizer speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "请开始说话");
speechRecognizer.startListening(intent);
speechRecognizer.setRecognitionListener(new RecognitionListener() {
@Override
public void onReadyForSpeech(Bundle bundle) {}
@Override
public void onBeginningOfSpeech() {}
@Override
public void onRmsChanged(float v) {}
@Override
public void onBufferReceived(byte[] bytes) {}
@Override
public void onEndOfSpeech() {}
@Override
public void onError(int i) {}
@Override
public void onResults(Bundle bundle) {
ArrayList<String> resultList = bundle.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
if (resultList != null && !resultList.isEmpty()) {
String result = resultList.get(0);
// 处理语音转文字结果
}
}
@Override
public void onPartialResults(Bundle bundle) {}
@Override
public void onEvent(int i, Bundle bundle) {}
});
}
```
在以上示例代码中,通过SpeechRecognizer类创建语音识别器,启动语音识别功能,然后通过RecognitionListener监听语音转文字结果,最终获取转换后的文本结果作为处理的依据。
