Voice Trainer

The Voice trainer is originally developed for people with a poorly intelligible speech due to Parkinson's disease , but is also suitable for professional speakers and in consultation with a speech therapist for people with another voice or speech disorder. With one dot on the screen, the app provides real time visual feedback on both loudness and pitch of the voice, allowing to see directly which aspect should be adjusted. You can use the app to make it easier to independently practice your speaking technique, but also to check if you speak properly during conversation. Together with your speech therapist you determine the optimal loudness and pitch. In Parkinson's disease or parkinsonism the app is used during speech therapy with the Pitch Limiting Voice Treatment ( PLVT ) , the Dutch method to effectively treat intelligibility problems in Parkinson's patients. The Voice trainer is therefore also called PLVT app. For additional options, the ‘Voice trainer Supplement’ is available.

Technical updates have been applied to make sure the app keeps working properly.
