Visual Feedback for Voice and Speech

TheraVox is an exceptional computer-based real-time visualization tool for voice and speech characteristics like voicing/voice onset, loudness (intensity), articulation/coarticulation and prosody, designed with affection and care. It provides a visual biofeedback of quantitative and qualitative characteristics of a patient’s voice/speech and therefore contributes to the enhancement of a patient’s self-perception and motivation.


The high motivational effect of computer-based exercises varying from easy to demanding allows a specific and goal-oriented treatment of a patient. For this reason, strenuous exercises based on limited self-perception of the patient can be made with less effort and more fun leading to highly positive effects on the therapy progress.
TheraVox is a very modern and handy program developed in cooperation with specialists.

TheraVox comes as a complete system with software, printed handbook and a tested USB microphone.

DWReview 1: In summary, TheraVox provides an enhanced visual biofeedback tool from what has previously been available on the market for working with children who have a variety of verbal communication deficits. The creators of this program have obviously gone to great extent to provide motivating animation and reinforcement for the child as well as ease of use for the therapist.
