suh-KY-uh-tree, or sy-KY-uh-tree. The "p" is completely silent. The first "y" is often the indefinite "uh-"-like "schwa" sound. The "i" is a "long i," pronounced like "eye." The "a" is another schwa. And the final -y is like a long "e", so the -try is like the word "tree." In the adjectival form, "psychiatric," everything changes! "sy-kee-AT-trick."
