Thank you for your question and welcome to Just Answer.
I'll try my best to sound it out for you!
Fre -> The "e" is an e like in "eh" or "en". Not a hard "E" like tree. Fre would sound like "freh".
tte -> is pronounce like "tay". Exactly ike the word "day", but with a "t".
So the whole word is pronounced like "freh-tay".
I hope this helps! If so, please don't forget to "Accept!"
Regards,
Ryan
