前言
国内语音识别技术已有多家,而olami不仅在语音识别上准确率较高,更重要的是在语义理解上十分强大,本文用olami sdk做了一个记账demo(记账部分代码参考开源代码),这个demo可以语音添加不同消费记录,查询当天,当月消费情况,删除消费列表中的记录。让我们一起来感受下olami如何实现强大的语义理解。
demo中实现的说法主要有如下几种(同类说法可以很多,没有全部列举):
今天餐饮开销一百元
今日交通出行五十元
本月15号日常购物一百元
这个月水电煤气两百元
查询今天的账单
查看今日的消费情况
今天的账单
今日消费
查询这个月的消费情况
查看本月消费
本月的账单
删除第一条
删除第一个记录
删除第五条消费记录
初始化部分参考源码MainActivity.Java中init()函数
public void init() { initHandler(); mOlamiVoiceRecognizer = new OlamiVoiceRecognizer(MainActivity.this); TelephonyManager telephonyManager=(TelephonyManager)this.getSystemService (this.getBaseContext().TELEPHONY_SERVICE); String imei=telephonyManager.getDeviceId(); mOlamiVoiceRecognizer.init(imei);//set null if you do not want to notify olami server. mOlamiVoiceRecognizer.setListener(mOlamiVoiceRecognizerListener);//设置识别结果回listener mOlamiVoiceRecognizer.setLocalization (OlamiVoiceRecognizer.LANGUAGE_SIMPLIFIED_CHINESE);//设置支持的语音类型,优先选择中文简体 mOlamiVoiceRecognizer.setAuthorization( "573031596fd746fca478e5cccf6ca9e2","asr","d5307ed38df64ab6a08e467c00c81d37","nli"); //注册Appkey,在olami官网注册应用后生成的appkey //注册api,请直接填写“asr”,标识语音识别类型 //注册secret,在olami官网注册应用后生成的secret //注册seq ,请填写“nli” mOlamiVoiceRecognizer.setVADTailTimeout(2000);//录音时尾音结束时间,建议填//2000ms mOlamiVoiceRecognizer.setLatitudeAndLongitude(31.155364678184498,121.34882432933009); //设置经纬度信息,不愿上传位置信息,可以填0 }
注册一个回调,用于各种回调,可以更新界面和处理服务器返回数据。
private class OlamiVoiceRecognizerListener implements IOlamiVoiceRecognizerListener{ @Override public void onError(int errCode) {//出错回调 mHandler.sendMessage(mHandler.obtainMessage( MessageConst.CLIENT_ACTION_ON_ERROR,errCode,0)); } @Override public void onEndOfSpeech() {//录音结束回调 mHandler.sendEmptyMessage(MessageConst.CLIENT_ACTION_STOP_RECORED); } @Override public void onBeginningOfSpeech() {//录音开始回调 mHandler.sendEmptyMessage(MessageConst.CLIENT_ACTION_START_RECORED); } @Override public void onResult(String result, int type) {//结果返回回调 mHandler.sendMessage(mHandler.obtainMessage( MessageConst.SERVER_ACTION_RETURN_RESULT, type, 0, result)); } @Override public void onCancel() {//取消录音回调 mHandler.sendEmptyMessage(MessageConst.CLIENT_ACTION_CANCEL_RECORED); } @Override public void onUpdateVolume(int volume) {//实时返回音量回调 mHandler.sendMessage(mHandler.obtainMessage( MessageConst.CLIENT_ACTION_UPDATA_VOLUME, volume, 0, null)); } }
本月15号日常购物200元,服务器返回数据如下:
[ { "desc_obj": { "result": "正在为您添加", "status": 0 }, "semantic": [ { "app": "account", "input": "本月15号日常购物200元", "slots": [ { "num_detail": { "recommend_value": "200", "type": "number" }, "name": "pay_number", "value": "200" }, { "name": "pay_type", "value": "日常购物" }, { "num_detail": { "recommend_value": "15", "type": "number" }, "name": "day", "value": "15" } ], "modifier": [ "pay" ], "customer": "58df512384ae11f0bb7b487e" } ], "type": "account" } ]
删除第一个记录, 服务器返回数据如下:
[ { "desc_obj": { "result": "正在为您删除", "status": 0 }, "semantic": [ { "app": "account", "input": "删除第一个记录", "slots": [ { "num_detail": { "recommend_value": "1", "type": "number" }, "name": "index", "value": "一" } ], "modifier": [ "delete_today" ], "customer": "58df512384ae11f0bb7b487e" } ], "type": "account" } ]
来看一下代码是如何解析的:
private void processServerMessage(String message) { try{ String input = null; JSONObject jsonObject = new JSONObject(message); JSONArray jArrayNli = jsonObject.optJSONObject("data").optJSONArray("nli"); JSONObject jObj = jArrayNli.optJSONObject(0); JSONArray jArraySemantic = null; if(message.contains("semantic")) { jArraySemantic = jObj.getJSONArray("semantic"); input = jArraySemantic.optJSONObject(0).optString("input"); } else{ input = jsonObject.optJSONObject("data"). optJSONObject("asr").optString("result"); } JSONObject jObjSemantic; JSONArray jArraySlots; JSONArray jArrayModifier; String type = null; String pay_number = null; String pay_type = null; String day = null; if(jObj != null) { type = jObj.optString("type"); if("account".equals(type))//应用的名称是account,代表记账应用 { jObjSemantic = jArraySemantic.optJSONObject(0); input = jObjSemantic.optString("input"); jArraySlots = jObjSemantic.optJSONArray("slots"); jArrayModifier = jObjSemantic.optJSONArray("modifier"); String modifier = (String)jArrayModifier.opt(0); if((jArrayModifier != null) && ("pay".equals(modifier))) {//modifier为pay,代表行为是记账 if(jArraySlots != null) { for(int i=0,k=jArraySlots.length(); i<k; i++) { JSONObject obj = jArraySlots.getJSONObject(i); String name = obj.optString("name"); if("pay_type".equals(name)) pay_type = obj.optString("value"); else if("pay_number".equals(name)) {//找出记录的具体金额 pay_number = obj.getJSONObject("num_detail"). getString("recommend_value"); } else if("day".equals(name)) {//找出某日发生消费的金额 day = obj.getJSONObject("num_detail"). getString("recommend_value"); } } } String date = null; Calendar localCalendar = Calendar.getInstance(); int i_year = localCalendar.get(Calendar.YEAR); int i_month = localCalendar.get(Calendar.MONTH)+1; int i_day = localCalendar.get(Calendar.DAY_OF_MONTH); if(day == null) { date = i_year + "-" + i_month + "-" + i_day; } else { date = i_year + "-" + i_month + "-" + day; } consumeClass trade = new consumeClass(0, Float.parseFloat("-"+pay_number), date, "123", pay_type, MainActivity.this); trade.trade_add(); //添加到消费列表中 } else if((jArrayModifier != null) && ("query_today".equals(modifier))) { QueryByTodayActivity.refreshListView( QueryByTodayActivity.QUERY_BY_DAY); //查询当天的消费情况,并更新列表 } else if((jArrayModifier != null) && ("query_month".equals(modifier))) { QueryByTodayActivity.refreshListView( QueryByTodayActivity.QUERY_BY_MONTH); //查询当月的消费情况,并更新列表 }else if((jArrayModifier != null) && ("delete_today".equals(modifier))) {//找出要删除的消费记录的索引,删除并更新界面 String index = null; if(jArraySlots != null) { JSONObject obj = jArraySlots.getJSONObject(0); index = obj.getJSONObject("num_detail"). getString("recommend_value"); } if(index != null && !"".equals(index)) QueryByTodayActivity. deleteTodayDataByIndex( Integer.parseInt(index)); } } } } catch(Exception e) { e.printStackTrace(); } }
