该功能是基于百度智能云实现的根据文字进行语音播报。
1、首先到百度智能云创建语音应用
https://console.bce.baidu.com/ai/
填写包名创建百度语音应用，获取AppID，API Key，Secret Key
2、导入资源文件。语音jar，assets语音库，jni系统文件
3、创建工具类
4、activity初始化语音引擎
protected String appId = "20729771";protected String appKey = "6SSdraj9RFUKyAmf36DcpYy3";protected String secretKey = "dmqQYTXsPUmWwgSQU06vj2plHKTAdaF3";
protected TtsMode ttsMode = TtsMode.MIX;protected MySyntherizer synthesizer;
SpeechSynthesizerListener listener;
protected String offlineVoice = OfflineResource.VOICE_MALE;在Application的onCreate方法里面初始化
Map<String, String> params = getParams();
InitConfig initConfig = new InitConfig(appId, appKey, secretKey, ttsMode, params, listener);synthesizer = new MySyntherizer(this,initConfig,null);
开始播报内容
synthesizer.speak(str1);

附：切换声音类型dialog
AlertDialog.Builder builder = new AlertDialog.Builder(SynthActivity.this, android.R.style.Theme_Holo_Light_Dialog);
builder.setTitle("引擎空闲时切换");
final Map<String, String> map = new LinkedHashMap<>(4);
map.put("离线女声", OfflineResource.VOICE_FEMALE);
map.put("离线男声", OfflineResource.VOICE_MALE);
map.put("离线度逍遥", OfflineResource.VOICE_DUXY);
map.put("离线度丫丫", OfflineResource.VOICE_DUYY);
final String[] keysTemp = new String[4];
final String[] keys = map.keySet().toArray(keysTemp);
builder.setItems(keys, new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {loadModel(map.get(keys[which]));Log.i("lgq","....."+map.get(keys[which]));}
});
builder.show();
方法二：
说明：只适用安卓6,0以上设备
两个工具方法，即可实现语音播报
public interface TTS {void playText(String playText);void stopSpeak();
}public class SystemTTS extends UtteranceProgressListener implements TTS, TextToSpeech.OnUtteranceCompletedListener {private Context mContext;private static SystemTTS singleton;private TextToSpeech textToSpeech; // 系统语音播报类private boolean isSuccess = true;public static SystemTTS getInstance(Context context) {if (singleton == null) {synchronized (SystemTTS.class) {if (singleton == null) {singleton = new SystemTTS(context);}}}return singleton;}private SystemTTS(Context context) {this.mContext = context.getApplicationContext();textToSpeech = new TextToSpeech(mContext, new TextToSpeech.OnInitListener() {@Overridepublic void onInit(int i) {//系统语音初始化成功if (i == TextToSpeech.SUCCESS) {int result = textToSpeech.setLanguage(Locale.CHINA);textToSpeech.setPitch(1.0f);// 设置音调，值越大声音越尖（女生），值越小则变成男声,1.0是常规textToSpeech.setSpeechRate(1.0f);textToSpeech.setOnUtteranceProgressListener(SystemTTS.this);textToSpeech.setOnUtteranceCompletedListener(SystemTTS.this);if (result == TextToSpeech.LANG_MISSING_DATA|| result == TextToSpeech.LANG_NOT_SUPPORTED) {//系统不支持中文播报isSuccess = false;}}}});}public void playText(String playText) {if (!isSuccess) {Toast.makeText(mContext, "系统不支持中文播报", Toast.LENGTH_SHORT).show();return;}if (textToSpeech != null) {textToSpeech.speak(playText,TextToSpeech.QUEUE_ADD, null, null);}}public void stopSpeak() {if (textToSpeech != null) {textToSpeech.stop();}}// public boolean isSpeaking() {
// if (textToSpeech.isSpeaking()) {
// return true;
// }
// return false;
// }//播报完成回调@Overridepublic void onUtteranceCompleted(String utteranceId) {}@Overridepublic void onStart(String utteranceId) {}@Overridepublic void onDone(String utteranceId) {}@Overridepublic void onError(String utteranceId) {}
}
调用播报：
SystemTTS systemTTS = SystemTTS.getInstance(MainActivity.this);
systemTTS.playText("支付宝到账一百万");
语音识别 实现
语音识别比较简单，只需要引入百度的代码库即可实现
实现效果
