Hi Shelleygarza0430,
Based on the description you provided, it would appear that the speakers of your AirPods are working as expected, but the microphones may not be.
The first step in possibly resolving this would be to ensure the AirPods including the microphone area are clean and free of debris or other obstructions. See How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods for the recommended steps to clean your AirPods.
You may also check to see if only one device is impacted by setting the microphone to only use the left device, test, then set to only use the right device and test. Change the settings of your AirPods and AirPods Pro shows how:
"Set Microphone to left, right, or automatic
There's a microphone in each AirPod, so you can make phone calls and use Siri. By default, Microphone is set to Automatic, so that either of your AirPods can act as the microphone. If you're using only one AirPod, that AirPod will be the microphone.
You can also set Microphone to Always Left or Always Right. You can also set Microphone to Always Left or Always Right to always have either the right or the left AirPod use the microphone even if you remove it from your ear or put it in the case."
Finally, to test this yourself you may try recording Voice Memos or audio replies in Messages whereby you can play back the recording to gauge whether this could be related to your call connection or device interference.
Regards.
