场景:进入程序后处于语音唤醒状态,当说到某个关键词的时候打开某个子界面(如:语音识别界面)
技术要点:
1、
// 设置唤醒一直保持,直到调用stopListening,传入0则完成一次唤醒后,会话立即结束(默认0)
mIvw.setParameter(SpeechConstant.KEEP_ALIVE, "1");
2、添加资源文件appid.jet 很奇怪为什么这里demo里面不需要语法文件
关键代码:
/*********************************语音唤醒************************************************/ // 语音唤醒对象 private VoiceWakeuper mIvw; // 唤醒结果内容 private String resultString; private void initAwake() { StringBuffer param = new StringBuffer(); String resPath = ResourceUtil.generateResourcePath(MainActivity.this,RESOURCE_TYPE.assets, "ivw/" + getString(R.string.app_id) + ".jet"); param.append(ResourceUtil.IVW_RES_PATH + "=" + resPath); param.append("," + ResourceUtil.ENGINE_START + "=" + SpeechConstant.ENG_IVW); boolean ret = SpeechUtility.getUtility().setParameter( ResourceUtil.ENGINE_START, param.toString()); if (!ret) { Log.d(TAG, "启动本地引擎失败!"); } // 初始化唤醒对象 mIvw = VoiceWakeuper.createWakeuper(this, null); //非空判断,防止因空指针使程序崩溃 mIvw = VoiceWakeuper.getWakeuper(); if(mIvw != null) { // resultString = ""; // textView.setText(resultString); // 清空参数 mIvw.setParameter(SpeechConstant.PARAMS, null); // 唤醒门限值,根据资源携带的唤醒词个数按照“id:门限;id:门限”的格式传入 mIvw.setParameter(SpeechConstant.IVW_THRESHOLD, "0:"+ 0); //20为门阀值 // 设置唤醒模式 mIvw.setParameter(SpeechConstant.IVW_SST, "wakeup"); // 设置唤醒一直保持,直到调用stopListening,传入0则完成一次唤醒后,会话立即结束(默认0) mIvw.setParameter(SpeechConstant.KEEP_ALIVE, "1"); // mIvw.startListening(mWakeuperListener); //onresume中操作 } else { showTip("唤醒未初始化"); } } private WakeuperListener mWakeuperListener = new WakeuperListener() { @Override public void onResult(WakeuperResult result) { try { String text = result.getResultString(); resultString = text; JSONObject object; object = new JSONObject(text); String awakeId = object.optString("id"); if(!StringUtil.isNullorEmpty(awakeId)) { //打开语音识别界面 boolean needShowVoiceTips = (Boolean) SPUtils.get(MainActivity.this,getResources().getString(R.string.needShowUseVoiceTips), true); Log.v(TAG, "IsShowVoiceTips="+needShowVoiceTips); mIvw = VoiceWakeuper.getWakeuper(); if (mIvw != null) { mIvw.stopListening(); mIvw = null; } else { showTip("唤醒未初始化"); } if(!needShowVoiceTips) { if(voicePop==null||!voicePop.isShowing()) { voicePop = new VoiceInputPopView(MainActivity.this); //显示窗口 voicePop.showAtLocation(iv_setting, Gravity.CENTER, 0, 0); //设置layout在PopupWindow中显示的位置 } } else { voidTipsPop= new UseVoiceTipsPop(MainActivity.this); //显示窗口 voidTipsPop.showAtLocation(iv_setting, Gravity.CENTER, 0, 0); //设置layout在PopupWindow中显示的位置 } } } catch (JSONException e) { resultString = "结果解析出错"; e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } // Toast.makeText(MainActivity.this, "结果"+resultString, Toast.LENGTH_SHORT).show(); } @Override public void onError(SpeechError error) { showTip(error.getPlainDescription(true)); } @Override public void onBeginOfSpeech() { showTip("尝试说【讯飞语点】唤醒语音识别界面"); } @Override public void onEvent(int eventType, int isLast, int arg2, Bundle obj) { } };
