Joint Speech is speech produced when one or more people say the same thing at the same time. This kind of speaking is commonly found in practices of prayer, in protest, and on the terraces of football matches. It is found in classrooms and courtrooms. To those who take part, it is a very important kind of activity. Yet it has hardly been studied from a scientific or empirical point of view at all.
This website provides material and documentation to those interested in studying joint speech. Here you will find some illustrative examples, an extensive archive of recordings of joint speech, and a collection of papers and texts written on the subject.
A book on the topic, The Ground From Which We Speak: Joint speech and the collective subject, will be published by Cambridge Scholars in 2018. A short precis of the book is available, and all examples used in the book are provided here.
