var main = plus.android.runtimeMainActivity();
var SynthesizerPlayer = plus.android.importClass('com.iflytek.speech.SynthesizerPlayer');
var player = SynthesizerPlayer.createSynthesizerPlayer(main, 'appid=56d79095');
player.setVoiceName("vivixiaomei");
player.playText(nedConts, "ent=vivi21,bft=5", null);

请问大牛，大神门播放后如何停止/暂停/继续？
