There is an excellent radio interview with Voice hearer Eleanor Longden on Ron Jonsons show.
Click on this link to hear it.
Eleanor goes into great detail of her own experiences hearing voices. Her personal account gives a great insight to what it is like.
Nicely put together with music and poetry as well.
