I've been looking on how to copy javascript sound/voice from websites?
Anyone know how?
Sounds embedded inside the website? Why not try (in Firefox) Tools > Page Info > Media tab and see if they're in there. Could also be cached by your browser somewhere as well, e.g. temp internet files. Otherwise I suppose to actually get the source files from the website you'd have to look through the site source code and perhaps the .js scripts and find where the sound files are at, then download em.
You could also screen record and just trigger all the sounds and manually cut up the audio -> output to clips.
You weren't specific enough, so I'll just answer based on what I think you're asking - how to get the mp3 from sites that play them using a js player
You can use Live http headers to find the mp3 link.

2. Or if you want to record the sounds yourself, you can use audacity.
If you don't have stereo mix option on your computer, you need virtual audio cable.
If you have a mac you can use site sucker and get all the files on a site.

If your a chrome or safari user enable the web developer tools. The right click on the page and click inspect elements.
for example, this page:
http://30m.org/stm/freelander/
Will play the auto after you click the ok button.
Right click -> Inspect Element
Then click on the Network tab
(you may need to click enable in the network tab first)
Reload the page
Scroll down until you find the file in question (in this case the mp3 file)

Right click the filename:

And select "Open Link in new Tab" or "Copy Link Address"
Then download!!
This will word for videos as well -> note that you need to press play before you will see the video in the network tab
Cheers
