Intervoice is the umbrella organisation of the international Hearing Voices Movement. It consists of experts by experience (normally recovered or recovering voice hearers), as well as experts by training (professionals with or without their own voice hearing experience, scientists, etc.).
Hearing Voices Network
The Hearing Voices Networks in England (www.hearing-voices.org) and Germany (testing.netzwerk-stimmenhoeren.de/ ) are self-help organisations. The networks do regularly offer training in the efc approach in German and English-speaking countries. There are of course Hearing Voices Networks in many other countries, offering similar services.
Working to Recovery
Working to Recovery (www.workingtorecovery.co.uk/ ) is a recovery focussed training organisation with Ron Coleman and Karen Taylor as directors. Great parts of the international Hearing Voices Movement have been inspired, amongst others, by Coleman and Taylor.
