However, we can create one! Here's a tongue twister incorporating these sounds:
"The fluffy pheasant, full of fight, fought fiercely for his fluffy wife."
This tongue twister includes the following:
* "ph" as /f/ in "pheasant" and "fluffy"
* "gh" as /f/ in "fight" and "fought"
* The letter "f" in "fluffy," "fight," "fiercely," and "for"
This twister emphasizes the /f/ sound with different spellings and would definitely be tricky to say quickly!
