The Challenge Project

Fighting auditory hallucinations by using Virtual Reality simulation training

What is it?


CHALLENGE is a project to develop a novel therapy to aid people who suffer from auditory hallucinations, specifically, hearing malevolent voices.

Khora is developing the core software to support this novel treatment. The software includes a virtual reality simulation training program and voice modulation in real time, which will enable the patient to face their malevolent voices and lessen their control over the patient’s life.

The Challenge Project is a research project in collaboration with Region Hovedstaden in Denmark and funded by the Innovation Fund Denmark.

(DK) Virtual Reality skal hjælpe skizofrenipatienter med at bekæmpe stemmerne i hovedet


En ny behandlingsform skal gøre det lettere for patienter med alvorlige hørelseshallucinationer at kontrollere de plagsomme stemmer, de hører. VR-brillerne testes i Region Hovedstaden, Nordjylland og Syddanmark.

Why use VR simulation training?


The use of Virtual Reality allows exposure to challenging situations in an immersive, but also protected, flexible, and controlled environment. Exposure to auditory hallucination in real life is impossible to organize and control. VR exposure therapy can overcome or mitigate this problem by producing greater user acceptance and providing control over and access to situations.

With this project, we expect patients to be able to develop new skills and strategies to cope with their malevolent voices.

This type of treatment may also improve the cost effectiveness and efficacy of the current treatment of auditory hallucinations.

Who is involved in the project?

What makes this software unique?

Face Creation

Creating a visual representation of the patient’s malevolent voice, where gender, age, and facial characteristics are all customizable.

Voice Modulation

A recording of the therapist’ voice can be modulated – by changing age, gender, pitch, and other traits – to resemble the patient’s persecutory voice.

Real Time VR

The patient can engage in a dialogue with the visual representation of the malevolent voice in VR, where the therapist is acting as the voice via the real time voice modulation feature.
