Text-to-speech 入门与进阶学习笔记(android)
1,入门:让TEXT朗读起来 //1,先写一个用来检查tts是否安装的方法privatefinalstaticintCHECK_CODE=1; publicvoidcheckTts(){ IntentcheckIntent=newIntent();checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA); startActivityForResult(checkIntent,CHECK_CODE);} //创建一个TTS privateTextToSpeechmTts; //这个自己先去了解下onActivityResult是怎么回事,这里不作详解 @OverrideprotectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){ //TODOAuto-generatedmethodstubsuper.onActivityResult(requestCode,resultCode,data); if(requestCode==CHECK_CODE){ if(resultCode==TextToSpeech.Engine.CHECK_VOICE_DATA_PASS){ //成功创建一个TTS mTts=newTextToSpeech(this,this); }else{ //否则安装一个 IntentinstallIntent=newIntent();installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);startActivity (installIntent);}}} //2,让TTS朗读起来 //onCreate方法中 //检查TTS是否正常checkTts(); //创建用组件privatespeakValue=(EditText) findViewById(R.id.speakValue); privatespeakButton=(Button) findViewById(R.id.sayHello); speakButton.setOnClickListener(newOnClickListener(){ @Override publicvoidonClick(Viewv){ //TODOAuto-generatedmethodstub Stringtext=speakValue.getText().toString(); Log.d("result","text-->"+text);sayTts(text);}}); //TTs朗读用privatevoidsayTts(Stringtext){ //最简单的例子mTts.speak(text,TextToSpeech.QUEUE_FLUSH,null); } //补充,使用TTS朗读,一定要实现OnInitListener 接口 //TTs对象创建后初始化 @OverridepublicvoidonInit(intstatus){ if(status==TextToSpeech.SUCCESS){ //设置语言区域intresult=mTts.setLanguage(Locale.US); //如果是不支持语言 if(result==TextToSpeech.LANG_MISSING_DATA||result==TextToSpeech.LANG_NOT_SUPPORTED){ Log.e("error","不支持");}}} 就这么点代码就可以正常运行了… 2,进阶使用:改变我们朗读播放的类型,回调函数的使用与自定义文字发音 1,更改播放的流类型(暂且这样说,希望,有人解释一下) //更改播放使用的流类型 //在sayTts作以下修改 //TTs朗读用privatevoidsayTts(Stringtext){HashMap<String,String>myAlarm=newHashMap(); //把播放类型,通过闹钟流实现myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_STREAM,String.valueOf(AudioManager.STREAM_ALARM)); //你播放的tts在音频播放的闹钟类型流中mTts.speak(text,TextToSpeech.QUEUE_FLUSH,myAlarm); //英语原文是这样,我了解的就是以上我注释的内容 //我感觉不是很了解,希望有人帮帮 //OnAndroid,eachaudiostreamthatisplayedisassociatedwithone //streamtype,asdefinedinandroid.media.AudioManager.Foratalking //alarmclock,wewouldlikeourtexttobeplayedonthe //AudioManager.STREAM_ALARMstreamtypesothatitrespectsthealarm //settingstheuserhaschosenonthedevice. } 2,回调函数的使用 //在sayTts()中实现.. //需要实现OnUtteranceCompletedListener这个接口 //TTs朗读用 privateToasttoast;prvateContextcontext=getApplicationContext(); privatevoidsayTts(Stringtext){HashMap<String,String>myAlarm=newHashMap();mTts.setOnUtteranceCompletedListener(this); myAlarm.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"metoo"); toast=Toast.makeText(context,"metoo",Toast.LENGTH_LONG); //最简单的例子mTts.speak(text,TextToSpeech.QUEUE_FLUSH,myAlarm);} //回调函数@OverridepublicvoidonUtteranceCompleted(StringutteranceId){speakPlayBack(utteranceId);} privatevoidspeakPlayBack(Stringstr){Log.d("result","playBack-->"+str);toast.show();} 3,录制TTS朗读保存到SD卡中 //把TTS朗读结果保存 privatevoidsayTofile(Stringtext){ HashMap<String,String>ttsRender=newHashMap<String,String>(); StringdestFileName="/sdcard/tts/"+text+".wav";ttsRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,text);mTts.synthesizeToFile(text,ttsRender,destFileName); } //在 你就可以看到你刚才朗读的Text被保存了 4,自定义Text发音 //自定义文字播放 privatevoidsayTrue(Stringtext){ StringdestFileName="/sdcard/tts/"+text+".wav";mTts.addSpeech(text,destFileName); mTts.speak(text,TextToSpeech.QUEUE_FLUSH,null);} //在onclick方法中运行sayTrue(); 亲测,MP3也可以播放… 5,销毁 @OverrideprotectedvoidonDestroy(){super.onDestroy(); if(mTts!=null){ mTts.stop(); mTts.shutdown();}}
