Hi
Welcome to the MedHelp forum!
Yes, it could be auditory processing disorder, or it could be a speech disorder too. You could also be having a hearing problem or an auditory hallucination. Ear infections, and other causes of decreased hearing will need to be assessed by an ENT specialist. If you have not had one recently, please go for a complete neuro-psychiatric assessment.
Take care!
I am concerned about your hearing issues and feel you should see a specialist for a full exam and testing.
As for reading out loud, that may be anxiety related and could be further complicated by your other issues
