Android 中的离线语音识别

问题描述

我在 StackOverFlow 上搜索了很多关于这个问题，但线程已经超过 3 年了.

I searched a lot on StackOverFlow for this Problem but the Threads are older than 3 years old.

我实现了需要 Internet 连接的 Google 语音识别.搜索如何使用 Offline Voice Recognition 没有成功.

I implemented the Google Voice Recognition which requires a Internet Connection. Searching how i can use the Offline Voice Recognition brought no success.

现在离线时是否可以使用语音识别?

Is it now available to use the Voice Recognition when you're offline?

我的代码直到:

speechStartButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            promtSpeechInput();
        }
    });

private void promtSpeechInput() {
    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,
            "Recording...");
    try {
        startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
    } catch (ActivityNotFoundException e) {
        Toast.makeText(getApplicationContext(), "Language not supported", Toast.LENGTH_SHORT).show();
    }
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case CAMERA_PIC_REQUEST: {
            try {
                Bitmap image = (Bitmap) data.getExtras().get("data");
                ImageView imageView = (ImageView) findViewById(R.id.taskPhotoImage);
                imageView.setImageBitmap(image);

            } catch (NullPointerException e) {
                e.printStackTrace();
            }
        }
        case REQ_CODE_SPEECH_INPUT: {
         if(resultCode == RESULT_OK && null != data) {
             ArrayList<String> result = data
                     .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
             speechToTextField.setText(speechToTextField.getText()+" " +result.get(0));
         }
            break;
        }
    }
}

推荐答案

与 Google 无关.

Not with Google.

您必须使用另一种解决方案，例如 CMU Sphinx.在这里查看:Android:不使用谷歌服务器的语音识别

You have to use another solution like CMU Sphinx.Check here : Android: Speech Recognition without using google server
