Anyone knows how to stop subvocalisation??

Currently at school. Yipeee. With the cards ive been having a problem of subvocalisation lately. Hmm waiting for an email from Ben Pridmore (anyone who doesnt know Ben he was the WMC in 2004 and is currently ranked 2nd in the world, he is also a grandmaster) Lets see how we go. Also would anyone know of any flashcode generators??
