There's a pretty cool feature that I found on Knightlab which can embed audio directly on certain text. WordPress can use this but I'm not sure if it could be used here in a post.
This would be a great way for quotes and other usages. But I'm not a tech guy so I'm looking for your help

How about installing a third party text-to-speech software so you always get the audio for the text?
This is a mp3 demo, It's a test.

It seems that just like the onebox technology I mentioned in this article, audio files can also be embedded.
@Mike_Henry How did you upload audio file? I only know that I can upload images 
.
And will that be heavy for the service if we upload the audio directly?
That way it just for me subjectively and it doesn't work for Chinese.
I am using an external URL file, and the forum should not support uploading files other than pictures.
Questions about the operation of the forum should only be asked to the webmaster.
Ok, I got that. By the way, do you have any idea why this code doesn't work here?
<link href='https://cdn.knightlab.com/libs/soundcite/latest/css/player.css' rel='stylesheet' type='text/css'><script type='text/javascript' src='https://cdn.knightlab.com/libs/soundcite/latest/js/soundcite.min.js'></script>
Most public forums only allow normal users to send secure HTML code, so JavaScript scripts are not allowed.
That's unfortunate...but I see, thanks, Mike 
You're Welcome, It's My pleasure.
