Abstract
This study aimed to investigate the differences in the production of gestures in spontaneous
and planned speech. Given the cognitive link between speech and gesture (Kelly et al., 2010;
Peeters et al., 2015; McNeill, 2005, 2007) and the differences in the process of spontaneous
and planned speech production (Blaauw, 1995; Chawla & Krauss, 1994; Levelt, 1989), the
question that was answered was: What are the differences between the gestures that are
produced in spontaneous and planned speech? This research was conducted with the use of a
semi-structured sociolinguistic interview and a presentation by the same participants, in
which their co-speech gestures were analysed. The different types of gestures and the
synchronous speech showed various extents of structural congruity; metaphoric gestures and
speech were strongly congruent, beat gestures and speech did show some structural congruity
but to a lesser extent, and iconic gestures did not show structural congruence. The structural
congruity of metaphoric and beat gestures gives further evidence for the cognitive link
between speech and gesture.
