前言：

年前做了一期語音口令的年度活動，從語音錄製、上傳到智慧檢測，以及後續的語音播放元件，語音錄製的實現的方式是基於微信的JSSDK，本篇主要把語音錄製板塊整理了一下，供大家參考；

下一篇-音訊元件

各位看官先上眼：

H5實現移動端語音錄製功能

功能梳理：

檢視層
  • 定義動態效果狀態標識
    區分幾種錄製狀態
isAudioState: 0 // 0 未錄製or檢測完畢 1 錄製中 2 檢測中
：未錄製or檢測完畢     / 0 無動效
：錄製中               / 1 波浪紋
：檢測中               / 2 環形檢測
複製程式碼
  • 設定動態效果切換狀態
    通過監聽touchstart/touchend事件去切換動態效果
複製程式碼
邏輯層
 錄製、上傳、檢測功能
 時間限制（時間區間）、內容為空的相容處理
複製程式碼
  • touchstart事件中做了哪些事
    1.開啟錄音
2.切換錄音中狀態
3.開始計時，用於記錄音訊時長
複製程式碼
  • touchend事件中做了哪些事
    1.停止錄音
2.智慧檢測
3.控制錄音時長
4.上傳音訊
5.切換錄音結束狀態（是否開始檢測）
複製程式碼
USE API（JS-SDK）
 開始錄製 startRecord
 停止錄製 stopRecord
 智慧檢測 translateVoice （將語音轉文字）
 上傳音訊 uploadVoice （將錄製的臨時音訊檔案上傳至微信服務，供服務）
複製程式碼

這裡就不贅述了，可以去貓一眼微信的官方文件 點選前往

 注：所有邏輯均在此元件，父級元件引入即可

複製程式碼

注意事項：

  • 上述邏輯中均為同步操作，以應對服務端非同步獲取當次錄音的音訊檔案（目的在於需確報本次音訊上傳成功後再與服務端互動）；
  • 微信音訊格式為speex，需轉格；
  • 部分瀏覽器存在touch img呈現預覽模式的解決方案，img{ pointer-events: none; }；
  • audioStart時，部分瀏覽器存在使用者同時觸發下拉動作後鬆手無法touchend的情況，需preventDefault操作;
  • 米8在觸發上傳、檢測api時，會造成檢測動畫的卡頓，（其他機型沒問題），初步懷疑是執行緒阻塞，有興趣的可以一塊研究一下，歡迎科普哈~

服務端針對微信speek格式音訊優化

針對微信的speex高清音訊格式，服務端的小可愛做了以下處理； 處理音訊為前端可識別格式wav，並轉格為mp3，並再次壓縮；友好前端格式、提高的效率的同時又極大的節約了成本；有興趣的同學可以去看一下， 作者：purewater2014，微信高清音訊處理連結。

結語：

本篇簡要概述了H5語音的錄製模組，下一篇說一下本次活動中，類微信語音列表的render方式元件的實現；感謝，不當之處歡迎指正交流~
