我有一些代码可以将语音转换为文本,但只有在设备具有互联网连接时才会运行。我想看到我的代码脱机工作,为此我已经从stackoverflow和其他来源经历了几个代码,但我的代码仍然无法在离线模式下工作。
该设备是Moto X Play。启用离线语音识别功能。
这是我的代码。
private void promptSpeechInput() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
//intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,"en-US");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE,"en-US");
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,this.getPackageName());
intent.putExtra(RecognizerIntent.EXTRA_PREFER_OFFLINE,true);
//intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
//intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
需要帮助才能理解它,我想我错过了一些东西。
观察 没有其他应用允许离线模式。

我使用了下面的代码并且它在离线状态下进行:关注它(http://www.androidhive.info/2014/07/android-speech-to-text-tutorial/)
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_LANGUAGE, "en-US"));
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),getString(R.string.speech_not_supported),Toast.LENGTH_SHORT).show();
}
