This is a sub-issue of the larger fingerprint defense reorganization issue: #8787

API information:
https://developer.mozilla.org/en-US/docs/Web/API/SpeechSynthesis

Relevant API
https://developer.mozilla.org/en-US/docs/Web/API/SpeechSynthesis/getVoices

default protections: add a farbling-determined voice name to the list returned by getVoices, and have that name be an alias for the first name returned in the list
aggressive protection: have the API always return an empty list

What should we do when the voice list is empty?

Ah, so if there is nothing to alias against? Then, i think nothing to do there; if its default settings and the "true" value for getVoices is an empty list, then do nothing
