Question

我写了一个后台服务来查找用户的位置。现在我想在他的位置发生变化时向用户发送语音通知。我已经编写了用于确定位置更改和发送简单推送通知的代码，现在任何人都可以帮我制作语音通知或如何编写语音通知代码，或者是否有任何第三方库通过我们向用户发送语音通知。帮助赞赏。感谢

Answer 1

是的，最后我以非常简单的方式获得了它并提供了完整的解决方案。

private TextToSpeech myTTS;   // Define the TTS objecy
private int MY_DATA_CHECK_CODE = 0;

//write the following code in oncreate method or whereever you want to use this
{ 
    myTTS = new TextToSpeech(this, this);

    Intent checkTTSIntent = new Intent();
    checkTTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
    startActivityForResult(checkTTSIntent, MY_DATA_CHECK_CODE);
    speakWords("Pass the String here"); 
}

private void speakWords(String speech) {
    //speak straight away
    //myTTS.setLanguage(Locale.US);
    System.out.println(speech + " TTSTTTS");
    myTTS.speak(speech, TextToSpeech.LANG_COUNTRY_AVAILABLE, null);
}

public void onInit(int status) {
    // TODO Auto-generated method stub
    if (status == TextToSpeech.SUCCESS) {
        if(myTTS.isLanguageAvailable(Locale.US)==TextToSpeech.LANG_AVAILABLE)
            myTTS.setLanguage(Locale.US);
    } else if (status == TextToSpeech.ERROR) {
        Toast.makeText(getApplicationContext(), "Sorry! Text To Speech failed...", Toast.LENGTH_LONG).show();
    }
}

这是一个例子 link，你可能需要的部分粘贴在这里。

private TextToSpeech myTTS;

Intent checkTTSIntent = new Intent();
        checkTTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
        startActivityForResult(checkTTSIntent, MY_DATA_CHECK_CODE);
myTTS.speak(speech, TextToSpeech.QUEUE_FLUSH, null);

speakWords(words);  //call this function with the string you want as voice

        //speak the user text
private void speakWords(String speech) {
        //speak straight away
        myTTS.speak(speech, TextToSpeech.QUEUE_FLUSH, null);
}
    //act on result of TTS data check
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == MY_DATA_CHECK_CODE) {
        if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
            //the user has the necessary data - create the TTS
        myTTS = new TextToSpeech(this, this);
        }
        else {
                //no data - install it now
            Intent installTTSIntent = new Intent();
            installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            startActivity(installTTSIntent);
        }
    }
}
    //setup TTS  and don't forget to implement OnInitListener interface to use this method
public void onInit(int initStatus) {
        //check for successful instantiation
    if (initStatus == TextToSpeech.SUCCESS) {
        if(myTTS.isLanguageAvailable(Locale.US)==TextToSpeech.LANG_AVAILABLE)
            myTTS.setLanguage(Locale.US);
    }
    else if (initStatus == TextToSpeech.ERROR) {
        Toast.makeText(this, "Sorry! Text To Speech failed...", Toast.LENGTH_LONG).show();
    }
}

Answer 3

使用android文本语音api see reference here

Answer 4

在通知方法中（调用notificationManager.notify(0, notification);），添加以下内容：

try {
        Uri ring_uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), ring_uri);
        r.play();
} catch (Exception e) {
        // Error playing sound
}

每当您按下通知时，这都会发出通知。

android向用户发送语音通知
