假如現在有一個按鈕

  <div class="inp_btn voice_btn active" id="record">
                按住 說話
            </div>

下麵就是調用微信jssdk的方法

        var recorder;
        var btnRecord = $('#record');
        var startTime = 0;
        var recordTimer = 300;
        // 發語音

　上傳語音的方法　

 function uploadVoice() {
        //調用微信的上傳錄音介面把本地錄音先上傳到微信的伺服器
        //不過，微信只保留3天，而我們需要長期保存，我們需要把資源從微信伺服器下載到自己的伺服器
        wx.uploadVoice({
            localId: voice.localId, // 需要上傳的音頻的本地ID，由stopRecord介面獲得
            isShowProgressTips: 1, // 預設為1，顯示進度提示
            success: function (res) {
                // alert(JSON.stringify(res));
                //把錄音在微信伺服器上的id（res.serverId）發送到自己的伺服器供下載。
                voice.serverId = res.serverId;
                $.ajax({
                    url: '/QyhSpeech/DownLoadVoice',
                    type: 'post',
                    data: { serverId: res.serverId, Id: Id },
                    dataType: "json",
                    success: function (data) {
                        if (data.Result == true && data.ResultCode == 1) {
                            layer.open({
                                content: "錄音上傳完成！",//data.Message
                                btn: '確定',

                    }
                });

            }
        });
    }

　　後臺調用的方法需要一個ffmpeg.exe自行下載

 //下載語音並且轉換的方法
        private string GetVoicePath(string voiceId, string access_token)
        {
            string voice = "";
            try
            {
                Log.Debug("access_token:", access_token);
                //調用downloadmedia方法獲得downfile對象
                DownloadFile downFile = WeiXin.DownloadMedia(voiceId, access_token);
                if (downFile.Stream != null)
                {
                    string fileName = Guid.NewGuid().ToString();
                    //生成amr文件
                    string amrPath = Server.MapPath("~/upload/audior/");
                    if (!Directory.Exists(amrPath))
                    {
                        Directory.CreateDirectory(amrPath);
                    }
                    string amrFilename = amrPath + fileName + ".amr";
                    //var ss = GetAMRFileDuration(amrFilename);
                    //Log.Debug("ss", ss.ToString());
                    using (FileStream fs = new FileStream(amrFilename, FileMode.Create))
                    {
                        byte[] datas = new byte[downFile.Stream.Length];
                        downFile.Stream.Read(datas, 0, datas.Length);
                        fs.Write(datas, 0, datas.Length);
                    }
                    //轉換為mp3文件
                    string mp3Path = Server.MapPath("~/upload/audio/");
                    if (!Directory.Exists(mp3Path))
                    {
                        Directory.CreateDirectory(mp3Path);
                    }
                    string mp3Filename = mp3Path + fileName + ".mp3";
                    AudioHelper.ConvertToMp3(Server.MapPath("~/ffmpeg/"), amrFilename, mp3Filename);
                    voice = fileName;
              
                    Log.Debug("voice:", voice);
                }
            }
            catch { }
            return voice;
        }

　　調用GetVoicePath

 //下載微信語音文件
        public JsonResult DownLoadVoice()
        {
            var file = "";
            try
            {
                var serverId = Request["serverId"];//文件的serverId
                file = GetVoicePath(serverId, CacheHelper.GetAccessToken());
                return Json(new ResultJson { Message = file, Result = true, ResultCode = 1 });
            }
            catch (Exception ex)
            {
                return Json(new ResultJson { Message = ex.Message, Result = false, ResultCode = 0 });
            }

        }

　　文中需要 DownloadFile downFile = WeiXin.DownloadMedia(voiceId, access_token); 需要一個類庫到時候直接放到項目裡面即可（我也是找到）
