My speakerphone is not working

Hello,

For the past week Ive noticed that no one can hear me while I am on speakerphone. Ive tried resetting the phone, and changing sims, to no avail. I can however take calls normally, just not on speaker.

My question is will replacing the speaker on the lower right side of the phone fix the issue ? The speaker works fine when I play music.

It turns out the answer is no. The mic is attached to the lightning port module, a repair that involves removing almost everything in the phone.
