Italian Pronunciation:Leyh-Tee-Tzee-Ah"E" equals "Leyh." Stress your "I" in "Ti" to "EE." When tackling the "Z" keep fresh in mind the pronunciation of "Pizza"... in other words, "PEE-Tzah." Stress the following "I" after "Z" to "EE," once again. "A" is as in "Father." (Note: While "Zia" sounds "Zee-Ah" (with quiet, short stress), it is not uncommon to hear "Zyah," when spoken.)
