Answer:
Step-by-step explanation:
Jasmine's voice is so dang quiet Uchenna had to keep on asking, "What?" every time Jasmine whispered.
Ok, actually, her voice is mainly just noiseless or lowered. She is whispering faintly to Uchenna, and if she can't hear Jasmine, it tells you she is pretty dang quiet and muffled.
I used some words for quiet in that sentence; noiseless, lowered, faintly, quiet and muffled. They all describe a soft tone of speaking.
