Forums Scripts & Popups [Twitch] Can't prevent URLs from reading aloud

Trying to prevent links from being read out on my Twitch via speech. Copied script from friend, works for him and numerous others, but doesn't work for me.

on ^:text:http*:#:{

}
off ^:text:originalgamebug:#:{
speak $1-
}

Any ideas on how to get the URLs from reading out on mIRC would be greatly appreciated.
