@SaraSoueidan So you're specifically talking about a heading/label for the form as a whole? Something like a log-in form or an email newsletter subscription form where there's just the fields and then the call to action ("sign up", etc.) as the text on the submit button? I see someone else mentioned search forms, which I think are the most common unlabelled form, and you mentioned that there are specific roles for search now. But I don't know if AT by default looks at submit button text.
