The schwa sound is represented by the symbol ə.
Here's how the word breaks down:
* FOR - The "O" makes a long "O" sound.
* tu - This is where the first schwa sound is, represented by the "u".
* ne - This is where the second schwa sound is, represented by the "e".
So, phonetically, "fortune" would be pronounced as ˈfɔːr.tʃuːn.
