Cried out in a loud high-pitched voice (8)
I believe the answer is:
screamed
'cried out in a loud high-pitched voice' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for screamed that I've seen before include "Uttered loud cries" , "Cried out in a loud high-pitched voice" , "Yelled" , "Uttered a loud, high-pitched cry" , "Uttered a sudden high-pitched cry" .)
