On Android, you can use the contentDescription attribute to set an accessibility label.
You can also pass any kind of Span for greater control over pronunciation. For example, you can set a language by using LocaleSpan.
If another element is used to display the label, you can link the label by using the labelFor attribute.
// Set accessibility label
element.contentDescription = "Appt"
// Set accessibility label in Dutch language
val locale = Locale.forLanguageTag("nl-NL")
val localeSpan = LocaleSpan(locale)
val string = SpannableString("Appt")
string.setSpan(localeSpan, 0, string.length, Spanned.SPAN_INCLUSIVE_INCLUSIVE)
element.contentDescription = localeSpan
// Link visual label to field
textView.setLabelFor(R.id.editText)
