Connecting a bluetooth mic to a wired speaker through an Arduino without phones

Hey guys! I am new here and don't have much electronic experience..

I am looking for a way to pair a bluetooth mic to a bluetooth speaker without using a phone but I know that is impossible as both devices are slaves. Alternatively, someone suggested using a bluetooth receiver so the audio can be output to a speaker with an AUX cable. However, the problem I have is connecting the mic to the receiver without using a phone. The idea is for someone to be able to carry a mic around and have a speaker outputting the voice, like a loud speaker, without the need to have their phones.

Is this something feasible with an Arduino?

Thank you in advance!
