Hi Sean,
while your intention is certainly a great one, in practice this will almost certainly not be seen by blind and visually impaired users as a good thing.
One very significant reason for this is the speed of the voice. Unless you have a way for each user to customize the voice speed to an extreme degree, you will inevitably annoy many users in a very real sense.
Voice speed and the choice of voice itself are two very personal aspects of the UX that blind and visually impaired users take very seriously.
One user may have their voice speaking at a very slow rate whereas another may have it as fast as they can possibly make it. This is absolutely not an exaggeration and is not at all uncommon.
-Just wanted to give you a heads-up on this and also really do want to let you know that your intention is absolutely appreciated as well. It is always a welcome experience when a developer really wants to make the experience better for the blind / VI community.
thank you!
Cheers!
Cara

I want to make VO a first class user experience by swapping Siri’s voice with that of a voice actor’s.
I’m thinking I could override the getter for .accessibliltyLabel to fire my audio event before returning nil. I’m going to write a simple testing app to see the behavior, but I’m not very comfortable with this approach as the accessibility label is used by other aspects of the OS (notably UI automation testing) and it’s not really in keeping with OOP best practices.
I’d prefer to override that audio at the proper call site, which would might look like audioStreamForAccessibilityElement(), but if such an API exists it’s almost certainly outside of my App’s sandbox.
