[AndroidTips]调用TextToSpeech朗读的时候如何中间停顿
TTS在句子中间会停顿，你也可以通过在任何字符串中加点"."后面加空格来达到目的。最多可以有三个点，最后一个点后面加空格，没有空格可能不起作用。点越多停顿时间越长。

下面的代码中在一开始有一个长的停顿，然后在读消息体之前也有一个停顿：
private final BroadcastReceiver SMScatcher = new BroadcastReceiver() { @Override public void onReceive(final Context context, final Intent intent) { if (intent.getAction().equals( "android.provider.Telephony.SMS_RECEIVED")) { // if(message starts with SMStretcher recognize BYTE) StringBuilder sb = new StringBuilder(); /* * The SMS-Messages are 'hiding' within the extras of the * Intent. */ Bundle bundle = intent.getExtras(); if (bundle != null) { /* Get all messages contained in the Intent */ Object[] pdusObj = (Object[]) bundle.get("pdus"); SmsMessage[] messages = new SmsMessage[pdusObj.length]; for (int i = 0; i < pdusObj.length; i++) { messages[i] = SmsMessage .createFromPdu((byte[]) pdusObj[i]); } /* Feed the StringBuilder with all Messages found. */ for (SmsMessage currentMessage : messages) { // periods are to pause sb.append("... Message From: "); /* Sender-Number */ sb.append(currentMessage.getDisplayOriginatingAddress()); sb.append(".. "); /* Actual Message-Content */ sb.append(currentMessage.getDisplayMessageBody()); } // Toast.makeText(application, sb.toString(), // Toast.LENGTH_LONG).show(); if (mTtsReady) { try { mTts.speak(sb.toString(), TextToSpeech.QUEUE_ADD, null); } catch (Exception e) { Toast.makeText(application, "TTS Not ready", Toast.LENGTH_LONG).show(); e.printStackTrace(); } } } } }};?
