Talkie is an application for people who can't speak well. With Talkie you can type a short message. When you push on the speak button it will speak it out for you. But you can also show the text to someone else from a little distance. You can draw things as well.
There is a soundboard which contains preprogrammed sentences, but you add your own sentences as well to make it fit your own life. You can choose your favorite color and icon for every tile.
When you would like more languages. Install the Google TTS plugin and tab in the app on the settings icon.
