在Android上语音转文字

在Android上语音转文字

如果您不想使用

RecognizerIntent

进行语音识别，则仍然可以使用

SpeechRecognizer

该类来进行语音识别。但是，使用该类比使用意图要难一些。最后一点，我强烈建议让用户知道他何时被记录，否则，当他最终发现时，他可能会非常适应。

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,        RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,        "com.domain.app");SpeechRecognizer recognizer = SpeechRecognizer        .createSpeechRecognizer(this.getApplicationContext());RecognitionListener listener = new RecognitionListener() {    @Override    public void onResults(Bundle results) {        ArrayList<String> voiceResults = results     .getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);        if (voiceResults == null) { System.out.println("No voice results");        } else { System.out.println("Printing matches: "); for (String match : voiceResults) {     System.out.println(match); }        }    }    @Override    public void onReadyForSpeech(Bundle params) {        System.out.println("Ready for speech");    }        @Override    public void onError(int error) {        System.err.println("Error listening for speech: " + error);    }    @Override    public void onBeginningOfSpeech() {        System.out.println("Speech starting");    }    @Override    public void onBufferReceived(byte[] buffer) {        // TODO Auto-generated method stub    }    @Override    public void onEndOfSpeech() {        // TODO Auto-generated method stub    }    @Override    public void onEvent(int eventType, Bundle params) {        // TODO Auto-generated method stub    }    @Override    public void onPartialResults(Bundle partialResults) {        // TODO Auto-generated method stub    }    @Override    public void onRmsChanged(float rmsdB) {        // TODO Auto-generated method stub    }};recognizer.setRecognitionListener(listener);recognizer.startListening(intent);

重要说明：从UI线程运行此代码，并确保您具有必需的权限。
