Hi Chris: This is failing because it needs credit. Where did you get the code in utils.js?

Hey Chris,

I checked out the changed code and its looking a lot better! There are a few tiny things that need some adjusting:

• Move everything Announcer related to a separate folder within the Accessibility folder. (Don't forget to adjust the index.js to the src path)
• Move _textToSpeech out of the Announcer const, it seems like it's meant to be private.

@sandeep-vedam as discussed: can you please do some testing with this PR to validate if everything works as expected and evaluate if the documentation is clear enough. Thanks :)

Hey @chiefcll

I have tested this Announcer plugin with sample application(Router) and it seems to be fine.

Thanks, Sandeep.
