Hi there anti-screeches,
You offered some helpful information about your issue. You said that this is an ongoing issue, and it was happening on your original device the iPhone XR and is now happening on your new iPhone 14 Pro. Due to this, it sounds like the issue is related to your network. Ultimately you may want to reach out to Verizon and make them aware of this ongoing issue. Let them know that you changed devices, and the issue still follows.
However, Apple does offer some support for related issues. You can check out the recommended steps here: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker. Look at the last step one that page, as it is specific to your issue:
If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location.
We hope this information helps you out.
Kind regards!
