1. Push forward legislation/regulation/lawsuits/public opinion via whatever method is available, probably unions or other collective power.
2. Embrace the technology. Maybe build a voice model of yourself, sell the license affordably and broadly to those that want to take advantage of the convenience and scalability (as in number of phrases) of voice AI but don't want the mess of wading into unsettled legal territory. Or learn what voice AI is good at and what it is bad at and find your niche. Survive by being at the cutting edge of this new world, setting the standards and being knowledgable.
3. Walk away from an industry that is either dying or about to become unrecognizable.
The genie's not going back in the bottle.
