应用场景:足浴软件,技师钟房安排调派和队列排序查看,语音播报提醒。老程序是使用双屏显卡,windows系统PC上运行一个无人值守桌面程序。如今安卓机顶盒(WIFI)和MINI电视棒通过HDMI接口和支持大屏幕高清液晶显示器(电视)组合,让这一应用场景的成本大幅下降,实用性更好。
通过一番调研,发现国内上市公司科大讯飞的语音+SDK包口碑好,效果好,集成也方便。语音+支持离线应用,这是最主要的。集成过程走起:
1、下载DEMO程序。DEMO程序就包含了全部需要的资源。
2、SDK集成关键代码:
(1)SpeechSynthesizer 是 jar包里封装的语音合成对象她是我们的女主角。
// 语音合成对象 private SpeechSynthesizer mTts; public static String SPEAKER = "speaker";
从demo照抄实例化mTts的代码。调用方式应该是jar里封装好的方法外包调用,暂时不关注,先关注一下怎样用起来。
private void checkVoiceServiceIsInstalled() { // 检测语音引擎是否可用,如果没有安装自动安装 if (!checkSpeechServiceInstall()) { String assetsApk = "SpeechService.apk"; if (processInstall(this, assetsApk)) SpeechUtility.getUtility(this).setAppid("53c776aa"); return; } // 引擎初始化 SpeechUtility.getUtility(this).setAppid("53c776aa"); mTts = new SpeechSynthesizer(this, mTtsInitListener); }
(2)检查语音加引擎是否安装
/** * 执行本地安装 语音+ * * @param context * @param assetsApk * @return */ private boolean processInstall(Context context, String assetsApk) { try { Thread.sleep(30000); } catch (InterruptedException e) { e.printStackTrace(); } // 本地安装方式 if (!ApkInstaller.installFromAssets(context, assetsApk)) { Toast.makeText(activity_main.this, "安装语音引擎失败!", Toast.LENGTH_SHORT) .show(); return false; } return true; } /** * 检测科大讯飞语音+引擎是否安装 * * @return */ private boolean checkSpeechServiceInstall() { String packageName = "com.iflytek.speechcloud"; List<PackageInfo> packages = getPackageManager() .getInstalledPackages(0); for (int i = 0; i < packages.size(); i++) { PackageInfo packageInfo = packages.get(i); if (packageInfo.packageName.equals(packageName)) { return true; } else { continue; } } return false; } /** * 语音合成的参数设置 * * @param param * @return */ private void setParam() { mTts.setParameter(SpeechConstant.ENGINE_TYPE, sp.getString("engine_preference", "local")); if (sp.getString("engine_preference", "local") .equalsIgnoreCase("local")) { mTts.setParameter(SpeechSynthesizer.VOICE_NAME, sp.getString("role_cn_preference", "xiaoyan")); } else { mTts.setParameter(SpeechSynthesizer.VOICE_NAME, sp.getString("role_cn_preference", "xiaoyan")); } mTts.setParameter(SpeechSynthesizer.SPEED, sp.getString("speed_preference", "50")); mTts.setParameter(SpeechSynthesizer.PITCH, sp.getString("pitch_preference", "50")); mTts.setParameter(SpeechSynthesizer.VOLUME, sp.getString("volume_preference", "50")); }
(3)初期化监听,我在ErrorCode.SUCCESS初始化成功后显示语音引擎可用的状态,否则红叉显示不可以状态。合成回调监听,这里为了避免异步方式调用,听不清楚,使用了局部变量记录当前的语音播报状态isPlaySound。引擎支持异步调用,如果不控制会出现,一句话没说完,其他调用又在发起请求的情况,使用了队列来控制播报的顺序。
/** * 初期化监听。 */ private InitListener mTtsInitListener = new InitListener() { @Override public void onInit(ISpeechModule arg0, int code) { if (code == ErrorCode.SUCCESS) { btn_voiceDemo .setBackgroundResource(R.drawable.voice_enable_style); } else { btn_voiceDemo .setBackgroundResource(R.drawable.voice_disable_style); } } }; /** * 合成回调监听。 */ private SynthesizerListener mTtsListener = new SynthesizerListener.Stub() { @Override public void onBufferProgress(int progress) throws RemoteException { } @Override public void onCompleted(int code) throws RemoteException { activity_main.this.runOnUiThread(new Runnable() { @Override public void run() { int pos = voiceQueueList.indexOf(getCurrentVoiceEntity()); if (pos != -1) { currentVoiceEntity.setVoicePlayNum(currentVoiceEntity .getVoicePlayNum() + 1); voiceQueueList.remove(pos); if (currentVoiceEntity.getVoicePlayNum() > Integer .parseInt(sp .getString("voice_play_timers", "0"))) { currentVoiceEntity.setIsVoicePlayed(true); new ExecVoiceStatusChangeBiz().execute(String .valueOf(getCurrentVoiceEntity().getKeyId())); } voiceQueueList.add(currentVoiceEntity); } loadVoiceTaskList(); } }); isPlaySound = false; } @Override public void onSpeakBegin() throws RemoteException { isPlaySound = true; } @Override public void onSpeakPaused() throws RemoteException { } @Override public void onSpeakProgress(int progress) throws RemoteException { } @Override public void onSpeakResumed() throws RemoteException { } }; /** * 窗体销毁时释放语音服务资源 */ @Override protected void onDestroy() { super.onDestroy(); mTts.stopSpeaking(mTtsListener); mTts.destory(); }
3、完成。截图纪念一下:
