插件引入

var plugin = requirePlugin("WechatSI")  
let manager = plugin.getRecordRecognitionManager();

touchStart() 开始录音

touchStart: function() {   
                        manager.start({  
                            duration: 60000,  
                            lang: "zh_CN"

            },  

touchEnd() 结束录音

touchEnd: function() {  
                uni.showToast()  
                manager.stop();  
            }, 

initRecord() 语音回调

 initRecord: function() {  
                manager.onStart = function(res) {  
                    this.voiceState ="onStart:"+ res.msg+"正在录音"  
                };  
                //有新的识别内容返回，则会调用此事件  
                manager.onRecognize = (res) => {  
                    this.voiceState = res.result;  
                }  

                // 识别结束事件  
                manager.onStop = (res) => {  

                    this.voiceState = res.result;  
                }  

                // 识别错误事件  
                manager.onError = (res) => {  

                    this.voiceState = res.msg;  

                }  
            },

    <view>  
        <view class="voicepad">  
            {{voiceState}}  
        </view>
