How do I remove the small microphone icon on iPhone 15?

Hello, do you mean the orange dot in centre of Dynamic Island or in the right corner of your iPhone?

This dot indicates, that some app is using microphone. To remove the dot, you need to close the app which is using the mic.

Interesting that it doesn't show up in Apple's support article:

You may be referring to the orange dot, which means an app is using your microphone. To remove it, close the app that's using your mic. If this is a blue microphone icon, that means Voice Control is enabled.

If it's something else, please let us know. If you also provide a screenshot that would be very helpful.

I finally contacted a “voice’ at Apple. After about a half hour of discussion and many attempts at various possible fixes, she and I agreed to “reset” my iPhone. It finally worked but I never did figured out how I got in the mess to begin with. But just resolving the problem was enough for me.

Glad to hear your issue was resolved!

I have a similar issue. A little gray box floats along the edge of my iphone13. It has a quote balloon inside of which is an image I’m guessing is supposed to be frequency waves. I can move along the edges. If I swipe it, it expands - a small gray band, but now it has an orange mic. It can also expand to take up the whole screen. But I can swipe it back down to the little box. I’d send a screenshot, but it doesn’t show up in screenshots. I think it has something to do with speech to text, but I’ve gone thru accessibility and don’t see any way to remove it. I’m sure it’s simple, but I’ve swiped every which way, held my finger down on it. Can’t find the magic touch.
