Can I declare app-wide acronym substitution for voice-over?

Question

Being a data-centric app, I have lots of german legal acronyms for german laws in my app. An english example would probably be "Cx" being read as "Constitution". I have a handful of those acronyms, they can be found in various text fields, all across my app.

Is there a way to declare app-wide voice-over pronunciation rules for these acronyms as a developer? I would rather not implement manual text substitution for 100+ UITextViews...

Research so far:

• This document, talking about choosing systemwide acronym substitution, but as an end user. (under "Changing pronunciations in the Speech Dictionary")
• UIAccessibilityReadingContent seems to be talking about a general Design-Pattern, not about word level optimisation of the output.

I'm unaware of an app-wide pronoun citation table for VO. An easy workaround is to use a custom subclass of UITe xtView and override accessibilityLabel to return the label with the substituted phrase for each language's abbreviations.
