This is a great app. Anyone can use this app to read any written material. There's tons of personalities to choose from and mixed gender options. Rate of speed of speech and mood, are part of choice options. They have a great online business model of trying before buying. The only downside is not having personal choices of voices of people within your life to be AI voices. If the app became huge, maybe celebrity voice options could be available, in the same way Waze, the driving app does.
