simple solution why dont anyone make phone that work between hearing and deaf such as change voice to text inside the phone just like vco but only with typing text change into voice may be difficult part. I know it may ruin relay operators' jobs however at least it should stop the spams and give deafies more private rights using phone communication without using relay.
I dislike relay because of privacy issues, I dont trust them at all only if IT necessary to call relay such as make call to work, make order for food only ask to pay cash or check in person once they delivery the food.
