We were trying to use this app to communicate with an elderly person who lost hearing due wax buildup. The person can read and speak but could not hear even loud noises. We used Ava Voice to display our messages in large text, even screen casting to a television for easy reading. However, the person insisted on reading the message out loud. Of course Ava Voice transcribed her voice, too. That created a distortion of our verbal message and caused much confusion for the reader. If we turned off the microphone after speaking our message, the text disappeared or diminished to small font which the elderly person could not read. We are still looking for a different solution while trying to become more familiar with Ava. Ava Voice could be very good with a way to toggle the microphone without losing the large text display.
