Hi shonta_favors1,
Check out and complete the steps found in the article here: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker
Specifically the section that states:
"Clean your receivers and speakers
Remove all screen protectors, films, or cases from your device. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver is not blocked or dirty. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry."
If the issue remains after completing the steps, reach out to Apple Support directly to help check on your service options.
