Hello any accessibility gurus,
I want to have this button element, when tabbed on, would trigger the screen read of an input element instead.
I tried pointing the aria-labelledby from the button to the input, to have the input's aria-label being read out. But the button still reads out its own description, when tabbed on.
<fieldset>
<input type="radio" id="inputid" aria-label="read me">
<button aria-labelledby="inputid">don't read me</button>
</fieldset>
Is there a way to read another element's content?
Thank you,

Following Andy's comment, the input element is only visually hidden, so it was moved offscreen with css left: -10000px.
I believe aria-labelledby is not used according to the standards, which might explain undefined behaviour.
The Accessible Name and Description, step C mentions the following:
If the embedded control has role textbox, return its value.
That means that if an <input>, which has implicit role textbox, is used as part of an accessible name, not its label, but its value is used as the name.
Further, the ARIA standard on aria-labelledby reads:
If the interface is such that it is not possible to have a visible label on the screen, authors SHOULD use
aria-label[…]
The main purpose of aria-labelleby is to refer to part of the visible contents of an element like a <form> to label it. Most commonly, this would be a heading like <h2>.
The use case of this question is currently unclear to me. The example provided does not make sense with a single radio input.
<input> is completely hidden, visually and from assistive technology, why is it there in the first place? <input type="hidden"> would be the more correct input to use if the form data is needed
