Android调用自带TTS文本转语音引擎实现离线语音合成

-10-27更新补充：

Android 11需要在AndroidManifest.xml里面添加queries标签：

<manifest xmlns:android="/apk/res/android"xmlns:tools="/tools"package="com.xxxx.xxxxx"><queries><intent><action android:name="android.intent.action.TTS_SERVICE" /></intent></queries><application /></manifest >

只要手机带有语音助手的话一般就会存在中文语音引擎，如果没有的话需要额外下载中文的语音引擎，不然不支持中文。

开工，第一步，初始化：

private TextToSpeech tts;tts = new TextToSpeech(this, new TextToSpeech.OnInitListener() {@Overridepublic void onInit(int status) {if (status == TextToSpeech.SUCCESS) {int result = tts.setLanguage(Locale.CHINA);if (result != TextToSpeech.LANG_COUNTRY_AVAILABLE && result != TextToSpeech.LANG_AVAILABLE) {Toast.makeText(MainActivity.this, "TTS不支持中文", Toast.LENGTH_SHORT).show();}}}});

第二步，控制：

//设置语速tts.setSpeechRate(1.0f);//设置语调tts.setPitch(1.5f);//开始朗读tts.speak("朗读的文字内容", TextToSpeech.QUEUE_FLUSH, null,getString(R.string.app_name));

回调监听：

tts.setOnUtteranceProgressListener(new UtteranceProgressListener() {@Overridepublic void onStart(String utteranceId) {//utteranceId是speak方法中最后一个参数：唯一标识码}@Overridepublic void onDone(String utteranceId) {}@Overridepublic void onError(String utteranceId) {//这个onError方法已过时，用下面这个方法代替}@Overridepublic void onError(String utteranceId,int errorCode) {//这个方法代替上面那个过时方法}});

OK，代码部分完成，收工。接下来是参数解释：

setSpeechRate(float speechRate)
speechRate：速率：默认是1.0f，可选0.5f~2.0f
setPitch(float pitch)
pitch：音调：默认是1.0。貌似这个参数的设置不怎么起作用。
speak(final CharSequence text, final int queueMode,final Bundle params,final String utteranceId)
text：朗读的内容（长度4000以内）queueMode：队列模式：可选参数： TextToSpeech.QUEUE_FLUSH：打断已有朗读，立即朗读这段。TextToSpeech.UEUE_ADD：读完正在读的再读这段。params：请求的参数。可为空。可选参数名称： TextToSpeech.KEY_PARAM_STREAMTextToSpeech.KEY_PARAM_VOLUMETextToSpeech.KEY_PARAM_PANutteranceId：这个请求唯一的标识。
setLanguage(final Locale loc)
loc：语种可选参数：（以下是源码，可选参数为以下的字段名）
