Ah-kio? Or, as Stephen Fry does in the talking books, Ak-sio (which
sounds better to me?)

I seem to remember a pronunciation guide somewhere pronounced it
ah-sio.  However, I always said ach-io, based on the Latin origins
(ecclesiastical Latin, at any rate; I'm not sure how it would be
pronounced in Classical Latin).
