语音到文本在Android [英] Speech to Text on Android

问题描述

我期待创建一个应用程序，它具有语音到文本。

I am looking to create an app which has Speech to text.

我知道这种使用RecognizerIntent能力：<一href="http://android-developers.blogspot.com/search/label/Speech%20Input">http://android-developers.blogspot.com/search/label/Speech%20Input

I am aware of this kind of ability using the RecognizerIntent: http://android-developers.blogspot.com/search/label/Speech%20Input

不过 - 我不希望一个新的意图被弹出，我想要做的分析，我目前的应用程序中的某些点上，我不希望它弹出的东西了，说明它正在试图记录你的声音

However - I do not want a new Intent to be popped up, I want to do the analysis a certain points in my current app, and I dont want it to pop something up stating that it is currently attempting to record your voice.

有没有人对如何最好地做到这一点的任何想法。我也许想尝试狮身人面像4 - 但我不知道这是否会能够在Android上运行 - ？！有没有人有任何建议或经验

Has anybody any ideas on how best to do this. I was perhaps thinking of trying Sphinx 4 - but I dont know if this would be able to run on Android - has anyone got any advice or experience?!

我在想，如果我可以在这里改变code到也许没有打扰显示UI或按钮，只是做了处理：<一href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html">http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html

I was wondering if I could alter the code here to perhaps not bothering to show the UI or button and just do the processing: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html

干杯，

推荐答案

如果你不想使用 RecognizerIntent 做语音识别，你仍然可以使用<一href="http://developer.android.com/reference/android/speech/SpeechRecognizer.html">SpeechRecognizer类来做到这一点。但是，使用该类更棘手比使用意向一点点。最后一点，我会强烈建议让用户知道他什么时候被记录，否则他可能很成立，当他终于找到了。

If you don't want to use the RecognizerIntent to do speech recognition, you could still use the SpeechRecognizer class to do it. However, using that class is a little bit more tricky than using the intent. As a final note, I would highly suggest to let the user know when he is recorded, otherwise he might be very set up, when he finally finds out.

编辑：一个小例子启发（但改变）从<一个href="http://stackoverflow.com/questions/4559930/speechrecognizer-causes-anr-i-need-help-with-android-speech-api">this堆栈溢出进入

A small example inspired (but changed) from this stack overflow entry

    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) {
                Log.e(TAG, "No voice results");
            } else {
                Log.d(TAG, "Printing matches: ");
                for (String match : voiceResults) {
                    Log.d(TAG, match);
                }
            }
        }

        @Override
        public void onReadyForSpeech(Bundle params) {
            Log.d(TAG, "Ready for speech");
        }

        @Override
        public void onError(int error) {
            Log.d(TAG,
                    "Error listening for speech: " + error);
        }

        @Override
        public void onBeginningOfSpeech() {
            Log.d(TAG, "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);

重要提示：运行从UI线程此code。

Important: Run this code from the UI Thread.
