該功能是基于百度智能云實現的根據文字進行語音播報。

?

1、首先到百度智能云創建語音應用

https://console.bce.baidu.com/ai/

?

?填寫包名創建百度語音應用，獲取AppID，API Key，Secret Key

?

2、導入資源文件。語音jar，assets語音庫，jni系統文件

?

?3、創建工具類

?

4、activity初始化語音引擎

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);

?

開始播報內容

?

synthesizer.speak(str1);

?

附：切換聲音類型dialog

AlertDialog.Builder builder = new AlertDialog.Builder(SynthActivity.this, android.R.style.Theme_Holo_Light_Dialog); builder.setTitle("引擎空閑時切換"); final Map<String, String> map = new LinkedHashMap<>(4); map.put("離線女聲", OfflineResource.VOICE_FEMALE); map.put("離線男聲", OfflineResource.VOICE_MALE); map.put("離線度逍遙", OfflineResource.VOICE_DUXY); map.put("離線度丫丫", 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：

說明：只適用安卓6,0以上設備

兩個工具方法，即可實現語音播報

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; // 系統語音播報類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) {//系統語音初始化成功if (i == TextToSpeech.SUCCESS) {int result = textToSpeech.setLanguage(Locale.CHINA);textToSpeech.setPitch(1.0f);// 設置音調，值越大聲音越尖（女生），值越小則變成男聲,1.0是常規textToSpeech.setSpeechRate(1.0f);textToSpeech.setOnUtteranceProgressListener(SystemTTS.this);textToSpeech.setOnUtteranceCompletedListener(SystemTTS.this);if (result == TextToSpeech.LANG_MISSING_DATA|| result == TextToSpeech.LANG_NOT_SUPPORTED) {//系統不支持中文播報isSuccess = false;}}}});}public void playText(String playText) {if (!isSuccess) {Toast.makeText(mContext, "系統不支持中文播報", 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; // }//播報完成回調@Overridepublic void onUtteranceCompleted(String utteranceId) {}@Overridepublic void onStart(String utteranceId) {}@Overridepublic void onDone(String utteranceId) {}@Overridepublic void onError(String utteranceId) {} }

?調用播報：

SystemTTS systemTTS = SystemTTS.getInstance(MainActivity.this); systemTTS.playText("支付寶到賬一百萬");

語音識別 實現

語音識別比較簡單，只需要引入百度的代碼庫即可實現

實現效果
