Solution
Set language of text
On Android, you can use LocaleSpan to speak content in a specific language. Multiple LocaleSpan's can be embedded inside a SpannableString to speak content in multiple languages.
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.setText(string)
