Common Voice is a Mozilla project that builds datasets for speech recognition systems, in it's collection it has low resource, vulnerable and endangered languages, that have little representation in the digital world.
Adding a search by voice to Firefox, would provide a simple voice service for these languages.
Beside the good cause, with this blue ocean strategy, Firefox might have a comeback. The browser's red market already has tons of players, where as the voice search for disadvantaged languages is a blue market that ideally Mozilla would be the only player or there would be few players with no giant players. This is a new market waiting to be captured that giants would not bother to enter.
Let me know what you think?
What are the possible benefits if any?
Do you use search by voice more often on your smart phone, tablet, notebook, PC?
Here is a screenshot of this feature in Chrome:
