Well you seem to have sleeps in there, so the computer should be yielding to allow others to run, I guess I will need to actually test in-game, what peripheral are you using to say the text?

the speaker peripheral

the speaker thats made with a redstone block in the middle that says suff that you can hear** its in the misc peripheral page no spasific link
