In my opinion, the best way to achieve this faster is partnership of some sort with google and other big corporations especially smartphone giants like Apple, Samsung would be very helpful.
I think the same.
What for the person will pay for every minute of voice recording if the giants give this oportunity for free?
But to have technology like this in house will be better for big company than to the small.
biggest difference between giants who giving free same technology, everything what you record , gonna remain on their server

anryze will only available on the blockchain and is only accessable for the keyholder
i think
