android - 不同设备上的 Android 语音识别器

问题描述

在测试了多种不同的语音转文本方法后，我终于得出结论，问题出在我的特定设备上

第二个设备是使用自定义 sdk 的中文设备我想知道在 Android 中是否需要特定的服务来启用语音识别器，因为我确实安装了谷歌语音应用程序并使用 adb 和相同的方式启用了它问题不断出现

我应该使用一种方法或调试策略来查找此问题的根源。

public class STT extends AppCompatActivity implements RecognitionListener {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

//android view initialization removed

    String[] PERMISSIONS = {Manifest.permission.RECORD_AUDIO};
    if(!Function.hasPermissions(this, PERMISSIONS)){
        ActivityCompat.requestPermissions(this, PERMISSIONS, REQUEST_PERMISSION_KEY);
    }


    progressBar.setVisibility(View.INVISIBLE);
    speech = SpeechRecognizer.createSpeechRecognizer(this);
    speech.setRecognitionListener(this);
    recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE,
            "en");
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
            this.getPackageName());
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);

    /*
    Minimum time to listen in millis. Here 5 seconds
     */
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 5000);
    recognizerIntent.putExtra("android.speech.extra.DICTATION_MODE", true);




    recordbtn.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick(View p1)
        {
            progressBar.setVisibility(View.VISIBLE);
            speech.startListening(recognizerIntent);
            recordbtn.setEnabled(false);

            /*To stop listening
                progressBar.setVisibility(View.INVISIBLE);
                speech.stopListening();
                recordbtn.setEnabled(true);
