While it meets the technical definition of joint speech, this article approaches conversational speech in a highly conventional manner, as turn taking in a joint communicative exchange

Müller, V., Delius, J. A. M., & Lindenberger, U. (2018). Complex networks emerging during choir singing. Annals of the New York Academy of Sciences. doi:10.1111/nyas.13940 [abstract]

During singing, the choir functions as a superordinate system, or superorganism, that imposes boundary conditions on the dynamic features of the individual singers.

Von Zimmerman, Jorina and Richardson, Daniel C. (2017) Verbal Synchrony and Action Dynamics in Large Groups Frontiers in Psychology, 7:2034. [Available online]

In a group task that can only be solved collectively, groups who chanted in synchrony before taking part performed better and scored better on tests of memory and sense of afilliation.

Jasmin, K. M., Mc Gettigan, C., Agnew, Z. K., Lavan, N., Josephs, O., Cummins, F., and Scott, S. K. (2016) Cohesion and joint speech: Right hemisphere contributions to synchronized vocal production.The Journal of Neuroscience, 36(17):4669–4680. [Available online]

Here we use fMRI to demonstrate that cortical activity is markedly different when speaking in real-time synchrony with a live person, but not with a recording, even when the speaker does not know the difference themselves.

Cummins, F. (2014). Voice, (inter-)subjectivity, and real-time recurrent interaction. Frontiers in Psychology: Cognitive Science, 5(760) doi: 10.3389/fpsyg.2014.00760 [Available online]

Theoretical treatment of some of the remarkable features of joint speech. Argues that joint speech has contributed to the foundation of the shared human world.

Cummins, F. (2014). The remarkable unremarkableness of joint speech. In Proceedings of the 10th International Seminar on Speech Production, pages 73–77, Cologne, DE. [pdf]

Short paper arguing that the phonetic form of joint speech is relatively unremarkable, and that conventional approaches to the analysis and understanding of speech will miss that which is special about joint speech.

Zon, B. (2014). Science, Theology and the Simplicity of Chant: Victorian musicology at war. Journal of the History of Ideas, 75(3):439-469. [pdf]

Hilarious look back at Victorian views of chant, as both barbaric and divinely simple.

Phonetic analysis of joint speech in English and Mandarin.

Cummins, F. (2013). Towards an enactive account of action: Speaking and joint speaking as exemplary domains. Adaptive Behavior, 13(3):178-186. [pdf]

Theoretical article arguing that a useful technical vocabulary for discussion of joint speech is to be found in the theory of enaction.

Consideration of the challenges that joint speech throws up if we consider it as a special kind of synchronised movement.

Cummins, F. (2009). Rhythm as entrainment: The case of synchronous speech. Journal of Phonetics. 37(1):16-28 [pdf]

Phonetic study of synchronous speech. Examines the auditory information necessary to allow synchronisation.

Technical article describing a method for measuring just how synchronous two utterances are.

Cummins, F. (2004). Synchronization among speakers reduces macroscopic temporal variability. 26th Annual Meeting of the Cognitive Science Society, pp. 304-309. [pdf]

Getting people to speak in synchrony turns out to be a great way to reduce some of the variability inherent in speech production. Useful for phoneticians.

Cummins,F. (2003). Practice and performance in speech produced synchronously. Journal of Phonetics, 31(2):139-148.

Early article looking at the remarkable facility that all speakers seem to have to speak in unison with another.
