I mean a verb(word?) to describe the action of intentionally coughing as you speaking. (Shown as 'ahem' or 'cough' in dialogue.)
I cannot forget what she said, mixing in coughs with her words:
"There used to be before ... [cough] but not [cough] anymore."
(I've used [cough] to only show what I mean. I won't actually be writing it in the dialogue.)
EDIT: Can I say "I cannot forget what she said, interspersing her words with coughs." instead?
