在科大訊飛語音包的Mscdemo中它的方法都是寫在Activity中的，這樣其實并不是很好，因為Activity只是負責UI交互的，如果項目很簡單自然可以，但是一旦比較復雜肯定要自己定義很多包很多類，但是寫在Activity中的方法就不能被自己定義的類調用了，咋辦尼，那就把方法寫在自己的類里就行了。
準備工作：把Msc.jar包和libmsc.so拷貝到自己工程的libs目錄下，這樣才能用它的方法和類。libmsc.so一定要用自己Id下載的包，因為這個包和你的那個appid是綁定的，拷貝別人的是不行的，會有用戶校驗失敗的錯誤，我就困擾了很久很久。。。

以語音合成方法為例，我在自己的應用程序中需要調用它的合成函數，所以在自己的類里調用了它的synthetizeInSilence()方法。如下

?

[java]?view plaincopy

/**?

?*?使用SpeechSynthesizer合成語音，不彈出合成Dialog.?

*?@param?

*/??

private?void?synthetizeInSilence()?{??

????if?(null?==?mSpeechSynthesizer)?{??

????????????//創建合成對象.??

????????????mSpeechSynthesizer?=?SpeechSynthesizer.createSynthesizer(this);??

????????}??

????????//設置合成發音人.??

????????String?role?=?mSharedPreferences.getString(??

????????????????getString(R.string.preference_key_tts_role),??

????????????????getString(R.string.preference_default_tts_role));??

??????????

????????//設置發音人??

????????mSpeechSynthesizer.setParameter(SpeechConstant.VOICE_NAME,?role);??

????????//獲取語速??

????????int?speed?=?mSharedPreferences.getInt(??

????????????????getString(R.string.preference_key_tts_speed),??

????????????????50);??

????????//設置語速??

????????mSpeechSynthesizer.setParameter(SpeechConstant.SPEED,?""+speed);??

????????//獲取音量.??

????????int?volume?=?mSharedPreferences.getInt(??

????????????????getString(R.string.preference_key_tts_volume),??

????????????????50);??

????????//設置音量??

????????mSpeechSynthesizer.setParameter(SpeechConstant.VOLUME,?""+volume);??

????????//獲取語調??

????????int?pitch?=?mSharedPreferences.getInt(??

????????????????getString(R.string.preference_key_tts_pitch),??

????????????????50);??

????????//設置語調??

????????mSpeechSynthesizer.setParameter(SpeechConstant.PITCH,?""+pitch);??

????????//獲取合成文本.??

????????Editable?editable?=?mSourceText.getText();??

????????String?source?=?null;??

????????if?(null?!=?editable)?{??

????????????source?=?editable.toString();??

????????}??

????????//進行語音合成.??

????????mSpeechSynthesizer.startSpeaking(source,?this);??

????????showTip(String.format(getString(R.string.tts_toast_format),0?,0));??

????}??

這里會遇到幾個問題，一個是SpeechSynthesizer.createSynthesizer(this)方法中的this源程序是指Activity對象，因為這個參數要求是Context，即上下文對象，在Activity里可以寫this，在自己類里寫this就成指代類對象，自然報錯了。解決辦法是將自己的類繼承Application，可以用getApplicationContext()方法獲取Context對象。第二個錯誤就是mSharedPreferences，這里是定義很多參數，可有可無，不定義就用默認值，想定義就直接調用setParameter就可以了，在這偷個懶就用其默認值了，修改后的類書寫如下。

注意！！！還沒完，要到Manifest.xml文件的application標簽里加上你的類的位置，我的是android:name="dmcore.outputs.MyOutput"，當然還要加上那些uses-permission，如下：
<uses-permission
android:name="android.permission.RECORD_AUDIO" />
<uses-permission
android:name="android.permission.INTERNET" />
<uses-permission
android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission
android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission
android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission
android:name="android.permission.READ_PHONE_STATE" />
<uses-permission?
android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission?
android:name="android.permission.READ_CONTACTS"/>

主函數中先創建MyOutput對象，再調用SetParameter方法，再調用synthetizeInSilence()方法，參數傳入你想輸出的話，大功告成！！！
