Why is my iPad microphone getting used by accessibility?

Hi peter1234-

welcome to this Apple (user-to-user) Community!

Re: "why is my microphone getting used by accessibility : ngl i think im getting spied on"

Are you using any accessibility apps that need to use the microphone ? Eg: dictating text etc. ?

Apple support's article: Control access to hardware features on iPad – Apple Support (AU)

Eg: says:

"Before apps use the camera or microphone on your iPad, they’re required to request your permission and explain why they’re asking".

and you can:

"Review or change access to the camera, microphone, and other hardware features

1. Go to Settings  > Privacy & Security.
2. Tap a hardware feature, such as Camera, Bluetooth, Local Network, or Microphone.

The list shows the apps that requested access. You can turn access on or off for any app on the list.

Note: Whenever an app uses the camera (including when the camera and microphone are used together), a green indicator appears. An orange indicator appears at the top of the screen whenever an app uses the microphone without the camera. Also, a message appears at the top of Control Center to inform you when an app has recently used either."

Hope this helps :-)
