mui js 语言播报方法

使用过的一个简单的语言播报方法 ，直接调用即可

function speak(contents){
	 var speaktext=contents;//传入的值是需要播报的内容
	 switch(plus.os.name){
	      	case "iOS":
		      	var AVSpeechSynthesizer=plus.ios.importClass("AVSpeechSynthesizer");
			var AVSpeechUtterance=plus.ios.importClass("AVSpeechUtterance");
			var AVSpeechSynthesisVoice=plus.ios.import("AVSpeechSynthesisVoice");
			var sppech = new AVSpeechSynthesizer();
			var voice = AVSpeechSynthesisVoice.voiceWithLanguage("zh-CN");
			var utterance =  AVSpeechUtterance.speechUtteranceWithString(speaktext);
			utterance.setVoice(voice);
			sppech.speakUtterance(utterance);
			plus.ios.deleteObject(voice);
			plus.ios.deleteObject(utterance);
			plus.ios.deleteObject(sppech);
	      		break;
	      	case "Android":
		      	var main=plus.android.runtimeMainActivity();
			var SpeechUtility=plus.android.importClass("com.iflytek.cloud.SpeechUtility");
			SpeechUtility.createUtility(main,"appid=5a20bab9");
			var SynthesizerPlayer=plus.android.importClass("com.iflytek.cloud.SpeechSynthesizer");
			var play=SynthesizerPlayer.createSynthesizer(main,null);
			play.startSpeaking(speaktext,null);
	      	break;
	 }
	      		
	      		
}
