暂停电话铃声，同时通过文字说话的语音，然后恢复 [英] Pause Phone Ringtone while Speaking through Text To Speech and then Resume

问题描述

我想提出一个来电者说话的应用程序采用TTS它说话呼叫人姓名。我要暂停的铃声，而TTS说话然后又继续铃声。从我的研究，我们可以使用 AudioFocus （希望如此）。 反正我用下面的code

I am making a caller speaking application which speak caller name using TTS. I want to pause the ringtone while TTS is speaking then resuming the ringtone. From what i have researched we can use AudioFocus (hope so). Anyway i am using the following code

更新

我用这code现在。

I am using this code now.

public void speak(final String talk) throws InterruptedException {
     final AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
     int musicVolume= audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
     audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, musicVolume, 0);
     audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);

    int result = tts.setOnUtteranceProgressListener(new UtteranceProgressListener() {

        @Override
        public void onStart(String utteranceId) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onError(String utteranceId) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onDone(String utteranceId) {
            // TODO Auto-generated method stub
            audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
            System.out.println("done");
        }
    });
    HashMap<String, String> params = new HashMap<String, String>();
    params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");
    tts.speak(talk, TextToSpeech.QUEUE_FLUSH, params);
    System.out.println("speaking after tts is over" + talk+" "+result);

}

虽然铃声停止和 TTS 播放，但在 TTS 播放铃声将无法继续。我应该怎么办？

Although the Ringtone is stopped and tts is played but after tts is played Ringtone is not resumed. What should i do?

推荐答案

抓我的头两天，我终于做到了最后经过。对于所有那些谁想要实现这样的事情，但不能因此在这里做的是code

Finally after scratching my head for two days i finally did it. For all those who want to implement something like this but are unable to do so here is the code

public void speak(final String talk) throws InterruptedException {
    final AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    int ringVolume = audioManager
            .getStreamVolume(AudioManager.STREAM_RING);
    int musicVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
    currentRingVolume = ringVolume;

    musicVolume = (int) ((musicVolume * seekbarValue) / 100);

    if (PauseRingtone == true) {
        audioManager.setStreamVolume(AudioManager.STREAM_RING, 1,
                AudioManager.FLAG_SHOW_UI);
    } else {
        audioManager.setStreamVolume(AudioManager.STREAM_RING,
                ringVolume, AudioManager.FLAG_SHOW_UI);
    }

    audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, musicVolume, 0);

    int result = tts
            .setOnUtteranceProgressListener(new UtteranceProgressListener() {

                @Override
                public void onStart(String utteranceId) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onError(String utteranceId) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onDone(String utteranceId) {
                    // TODO Auto-generated method stub
                    System.out.println("done");
                    audioManager.setStreamVolume(AudioManager.STREAM_RING,
                            currentRingVolume, 0);
                }
            });
    HashMap<String, String> params = new HashMap<String, String>();
    params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "stringId");
    tts.speak(talk, TextToSpeech.QUEUE_FLUSH, params);
    System.out.println("speaking after tts is over" + talk + " " + result);

}

的解释： -

ringVolume - 得到的铃声的当前音量 .IE铃声音量在手机设置

ringVolume - gets the current volume of the ringtone .i.e ringtone volume set in the phone.

musicVolume - 得到的音乐当前的音量

currentRingVolume 只保留了 ringVolume 。

注意 - STREAM_RING 和 STREAM_MUSIC 是不同的东西。请参阅

Note- STREAM_RING and STREAM_MUSIC are different things. See

现在的基本想法是静音的铃声，而 TTS 在讲话，然后将其设置为previous值。

Now the basic idea is to mute the ringtone while TTS is speaking and then set it to previous value.

seekBarValue - 是我的搜索栏描绘了 TTS 卷WRT musicVolume 键，是可选的。

seekBarValue- is my SeekBar which depicts the level of the TTS volume w.r.t musicVolume and is optional.

PauseRingtone - 一个复选框preference 它检查是否要暂停的铃声，同时说话。如果真是集 AudioManager.STREAM_RING 到 1 即振动其他 ringVolume 即手机值，因此这两个 TTS 和铃声发挥在同一时间。

PauseRingtone- is a CheckBox Preference which checks whether we want to pause ringtone while speaking. If true is sets the AudioManager.STREAM_RING to 1 i.e. vibrate else ringVolume i.e. Phone Value, so both TTS and Ringtone play at the same time.

audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,musicVolume, 0) 

设定 TTS 的卷 musicVolume 。经过 TTS 已完成上讲即 onDone（）我们设置铃声<容积/ code>回 ringVolume 使用 currentRingVolume 。

sets the volume of TTS to musicVolume. After TTS has completed speaking i.e. in onDone() we set the volume of Ringtone back to the ringVolume using currentRingVolume.
