How does the Voice trainer work?
As soon as you start the Voice trainer, you will see a dot appear on your screen that is either green or red.
As you speak, the Voice trainer shows you with the dot whether you are speaking according to the set loudness and pitch. The dot:
- is green if you speak loud enough.
- is red if you speak too softly.
- is in the middle on the screen when you speak at the correct pitch.
- is high (or low) on the screen if you speak with a voice that is too high (or too low).
You can set the limits yourself in the Settings, but usually the speech therapist will do this for you, because learning to speak with the correct loudness and pitch is part of the training.
The manual explains the features of the Voice trainer and how to use them.

There is also an in-app available (€19.99), which allows the speaker to view performances. This is mainly intended for speakers who use the Voice trainer without a speech therapist.
For people with Parkinson's disease, it will soon be possible to have this extra option for free if the treating speech therapist has access to the Voice trainer's online dashboard through ParkinsonNet.
Because the Voice trainer shows you real-time whether you are speaking with the intended loudness and pitch, many people can benefit from it, such as:
- people with Parkinson's disease who talk with more difficulty,
- people with intelligibility problems due to ataxia,
- people who need to learn to speak louder in their work without forcing their voice, e.g. teachers, presenters, etc.
The Voice trainer is currently being studied with people with Parkinson's disease and with people with ataxia.
