前言:
年前做了一期语音口令的年度活动,从语音录制、上传到智能检测,以及后续的语音播放组件,语音录制的实现的方式是基于微信的JSSDK,本篇主要把语音录制板块整理了一下,供大家参考;
各位看官先上眼:
功能梳理:
视图层
-
定义动态效果状态标识
区分几种录制状态 isAudioState: 0 // 0 未录制or检测完毕 1 录制中 2 检测中 :未录制or检测完毕 / 0 无动效 :录制中 / 1 波浪纹 :检测中 / 2 环形检测
-
设置动态效果切换状态
通过监听touchstart/touchend事件去切换动态效果
逻辑层
录制、上传、检测功能
时间限制(时间区间)、内容为空的兼容处理
-
touchstart事件中做了哪些事
1.开启录音 2.切换录音中状态 3.开始计时,用于记录音频时长
-
touchend事件中做了哪些事
1.停止录音 2.智能检测 3.控制录音时长 4.上传音频 5.切换录音结束状态(是否开始检测)
USE API(JS-SDK)
开始录制 startRecord
停止录制 stopRecord
智能检测 translateVoice (将语音转文字)
上传音频 uploadVoice (将录制的临时音频文件上传至微信服务,供服务)
这里就不赘述了,可以去猫一眼微信的官方文档 点击前往
代码层:
注:所有逻辑均在此组件,父级组件引入即可

注意事项:
-
上述逻辑中均为同步操作,以应对服务端异步获取当次录音的音频文件(目的在于需确报本次音频上传成功后再与服务端交互);
-
微信音频格式为speex,需转格;
-
部分浏览器存在touch img呈现预览模式的解决方案,img{ pointer-events: none; };
-
audioStart时,部分浏览器存在用户同时触发下拉动作后松手无法touchend的情况,需preventDefault操作;
-
米8在触发上传、检测api时,会造成检测动画的卡顿,(其他机型没问题),初步怀疑是线程阻塞,有兴趣的可以一块研究一下~(方案:动画轨迹被阻塞/dom渲染被打断(gif),所以回调后,可以使用时间戳的方式重新绘制图片;其他类似场景也可以使用这种方案,当然针对性场景,具体情况还要重新定义~)
服务端针对微信speek格式音频优化
针对微信的speex高清音频格式,服务端的小可爱做了以下处理; 处理音频为前端可识别格式wav,并转格为mp3,并再次压缩;友好前端格式、提高的效率的同时又极大的节约了成本;有兴趣的同学可以去看一下, 作者:purewater2014,微信高清音频处理链接。
结语:
本篇简要概述了H5语音的录制模块,下一篇说一下本次活动中,类微信语音列表的render方式组件的实现;感谢,不当之处欢迎指正交流~
今天的文章H5实现移动端语音录制功能分享到此就结束了,感谢您的阅读。
