It's pronounced An-yoos?

Ever since I started attending Mass, I've been wondering what exactly the words are to the Agnus Dei, and how to pronounce them. I finally looked it up today, and found my attempted singing had been way off:

Agnus Dei, qui tolis peccata mundi,
(Ahn-yoos Deh-ee, kw-ee tolis pec-cah-ta mun-dee)
miserere nobis. (2x)
(mis-eh-ray-reh naw-biss*rhymes w/hiss)

Agnus Dei, qui tolis peccata mundi,
(Ahn-yoos Deh-ee, kw-ee tolis pec-cah-ta mun-dee)
dona nobis pacem.
(dough-na naw-biss paa-kem)

(Lamb of God, who take away sins of world,
have mercy on us.
Lamb of God, who take away sins of world,
grant us peace.)

(From my reading of the pronunciation guide in A Primer of Ecclesiastical Latin, John F. Collins, 1988 The Catholic University of America Press)
