HTML5 voice recording function works well on chrome and

Answer 1

As far as I knew, even on the latest iOS (iOS 10), recording voice on iOS using HTML5 is still impossible. Since all the browsers on iOS are limited to use UIWebView which Safari on iOS uses as well, Chrome on iOS is not able to support any API that can be used for media recording.
For example, recorder.js which you used are built on Media Capture API. If you check caniuse.com, you will find this API is not supported on iOS. (Also check the issue here).
MediaRecorder API is also a promising API but still not supported by Apple's browser.
