do you say chumosh, or chumish?
do you say poroshas vayeira or parshas vayeira?
do you say haftara or haft-oh-ra?
etc etc etc
Basically, we speak in a convenient way and not necessarily technically correct. The same goes for Good Yontiff and not yoim toiv, or mazel tov, and not mazol toiv.
When we say shema, you HAVE to be medakdek, not when talking to your friend.
(So everyone get a life, and talk about something real.)
