Android 语音播报功能demo

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() { @Override public 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() { @Override public 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 @Override public void onUtteranceCompleted(String utteranceId) { } @Override public void onStart(String utteranceId) { } @Override public void onDone(String utteranceId) { } @Override public void onError(String utteranceId) { } }

 调用播报：

SystemTTS systemTTS = SystemTTS.getInstance(MainActivity.this); systemTTS.playText("支付宝到账一百万");
