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 + "" + 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; },
