Voice Trainer

The Voice Trainer was originally developed for people who speak poorly as a result of Parkinson's disease, but is also suitable for professional speakers and in consultation with a speech therapist, for people with other voice or speech disorders.
The Voice trainer continuously displays visual feedback on both the loudness and the (speech) pitch of the speech with one dot on the screen, so that you can immediately see which aspect needs to be adjusted. You can use the app to practice your speaking technique more easily, but also to check if you speak well during conversation. It is the intention that you set the optimal loudness and pitch together with your speech therapist.

For this app more functionalities are available with the 'Voice trainer Expansion'
