微信小程序后台配置添加微信同声传译插件不再详述，具体可自行百度。
app.json添加这段代码：

  "plugins": {    "WechatSI": {      "version": "0.2.2",      "provider": "wx069ba97219f66d99"    }  }

util.js中添加

var plugin = requirePlugin("WechatSI")var innerAudioContext = wx.createInnerAudioContext();innerAudioContext.onError((res) => {  // 播放音频失败的回调})function playTTS(text) {  //need to add WXAPP plug-in unit: WechatSI  plugin.textToSpeech({    lang: "zh_CN",    tts: true,    content: text,    success: function (res) {      log("succ tts", res.filename)      innerAudioContext.src = res.filename;      innerAudioContext.play()    },    fail: function (res) {      log("fail tts", res)    }  })}function stopTTS() {  innerAudioContext.stop();}module.exports = {  playTTS: playTTS,  stopTTS: stopTTS,}

新建页面，在新页面的js里面添加这段代码

// Page外var pageSelf = undefined;var plugin = requirePlugin("WechatSI")let manager = plugin.getRecordRecognitionManager()  /**   * 生命周期函数--监听页面显示   */  onShow: function() {    manager.onRecognize = function (res) {      // console.log('manager.onRecognize')      // console.log(res)      // wx.showToast({      //   title: res.result,      // })      // cons.log("current result", res.result)    }    manager.onStop = function (res) {      console.log('manager.onStop')      console.log(res)//语音识别信息打印      wx.showToast({        title: res.result,      })      // UTIL.log("record file path", res.tempFilePath)      // UTIL.log("result", res.result)      //res.result is the asr result, change the follow step to your source      //NLI.process(res.result, pageSelf);    }    manager.onError = function (res) {      console.log('manager.onError')      console.log(res)//报错信息打印      wx.showToast({        title: res.msg,      })      // UTIL.log("error msg", res.msg)    }  },  //添加两个方法    touchdown_plugin: function() {    var _this = this    // UTIL.stopTTS();    manager.start({      duration: 30000,      lang: "zh_CN"    })  },  //手指松开  touchup_plugin: function() {    manager.stop();    wx.showToast({      title: '正在识别……',      icon: 'loading',      duration: 2000    })  },

在新页面的wxml里面添加这段代码

<button type="primary" style="border-radius: 20px;" class="btn-style" bindtouchstart="touchdown_plugin" bindtouchend="touchup_plugin">按下录音，松开结束</button>
