微信小程序语音聊天智能对话（demo）

项目中用到了 olami sdk把录音或者文字转化为用户可以理解的json字符串。

效果图

重要jS代码：

 //手指按下时 语音转文字
  voiceToChar:function(){
 var urls = app.globalData.slikToCharUrl;
 var voiceFilePath = that.data.filePath;
 if(voiceFilePath == null){
      console.log("[Console log]:File path do not exist!");
      wx.showModal({
        title: '录音文件不存在',
        content: '我也不知道哪错了，反正你就再试一次吧！',
        showCancel: false,
        confirmText: '确定',
        confirmColor: '#09BB07',
 })
 return;
 }
 var appkey = app.globalData.NLPAppkey;
 var appsecret = app.globalData.NLPAppSecret;
 var NLPCusid = app.globalData.NLPCusid;
    wx.showLoading({
      title: '语音识别中...',
 })
    wx.uploadFile({
      url: urls,
      filePath: voiceFilePath,
      name: 'file',
      formData: { "appKey": appkey, "appSecret": appsecret, "userId": NLPCusid },
      header: { 'content-type': 'multipart/form-data' },
      success: function (res) {
        wx.hideLoading();
 var data = JSON.parse(res.data);
 var seg = JSON.parse(data.result).seg;
        console.log("[Console log]:Voice to char:" + seg);
 if(seg == null || seg.length == 0){
          wx.showModal({
            title: '录音识别失败',
            content: "我什么都没听到，你再说一遍！",
            showCancel: false,
            success: function (res) {
 }
 });
 return;
 }
        that.addChat(seg, 'r');
        console.log("[Console log]:Add user voice input to chat list");
        that.sendRequest(seg);
 return;
 },
      fail: function (res) {
        console.log("[Console log]:Voice upload failed:" + res.errMsg);
        wx.hideLoading();
        wx.showModal({
          title: '录音识别失败',
          content: "请你离WIFI近一点再试一次！",
          showCancel: false,
          success: function (res) {
 }
 });
 }
 });
 },

olami 技术的识别语音代码：

// 发送语料到语义平台
  sendChat: function (e) {
 let word = e.detail.value.ask_word ? e.detail.value.ask_word : e.detail.value;
    console.log("[Console log]:User input:" + word);
    that.addChat(word, 'r');
    console.log("[Console log]:Add user input to chat list");
    that.setData({
      askWord: '',
      sendButtDisable: true,
 });
    that.sendRequest(word);
 },
 // 发送请求到语义平台
  sendRequest(corpus){
    app.NLIRequest(corpus, {
 'success': function (res) {
 if (res.status == "error") {
          wx.showToast({
            title: '返回数据有误！',
 })
 return;
 }
 var resjson = JSON.parse(res);
 var data = JSON.stringify(resjson.data);
        that.NLIProcess(data);
 },
 'fail': function (res) {
        wx.showToast({
          title: '请求失败！',
 })
 return;
 }
 }); 
 },
 // 处理语义
 NLIProcess: function(res){
 var nlires = JSON.parse(res);
 var nliArray = nlires.nli;
 if(nliArray == null || nliArray.length == 0){
      wx.showToast({
        title: '返回数据有误！',
 })
 return;
 }
 var answer = nliArray[0].desc_obj.result;
 if(answer == null){
      wx.showToast({
        title: '返回数据有误！',
 })
 return;
 }
    console.log("[Console log]:Add answer to chat list...");
    that.addChat(answer, 'l');
 var dataArray = nliArray[0].data_obj;
 if(dataArray != null && dataArray.length > 0){
 var objType = nliArray[0].type;
 if(objType == 'selection' && dataArray.length > 1){
        that.newsProcess(dataArray);
 return;
 }
 if (objType == 'news' && dataArray.length == 1) {
        console.log("[Console log]:Add news to chat list...");
 var title = dataArray[0].title;
 var detail = dataArray[0].detail;
 var news = title + "\n" + detail; 
        that.addChat(news, 'l');
 return;
 }
 var content = dataArray[0].content;
 if (content != null && content != answer){
        console.log("[Console log]:Add content to chat list...");
        that.addChat(content, 'l');
 }
 }
 return;
 },
