Thanks for the info! My macbook has been running in overdrive ever since I installed leopard and I could never figure out why... I don't know why I didn't think to look at the activity monitor until now... but Speech Synthesis Server was taking up 92% of CPU activity! As much as I like my mac to speak to me, it's not worth the excessive strain on the fan. If anyone figured out a way to enable the clock to speak without this, please let me know. Thanks!
