Let's have fun communicating with this intonation control app developed by dentists.

This application takes a picture of your mouth with the internal camera and easily generates intonation-based audio by operating the screen, allowing you to freely add intonation and sing.
Follow the instructions on the screen to set up the app to suit your environment.
You can fine-tune the sound source generation to your liking. You can change the pitch and volume in real time by tracing the operation screen with your finger.

Also, if you are in a situation where it is difficult to speak, you can easily ask for help by showing the screen to the person you want to ask for help with and pressing the button for any word, which will play a voice reading that word out loud.
You can also create and add your own words to be played in the voice, which will be a great help in communicating with the other person.
Other convenient functions include a help mark and LED flash notification.
