Effects of Time Pressure and Spontaneity on Phonotactic Innovations in German Dialogues

Petra Wagner, Sina Zarrieß, Joana Cholin

Speech variation is often explained by speakers’ balancing of production constraints (favoring phonetic reduction of high frequency, expected items) and listener orientation (favoring more canonical productions for low frequency, unexpected items). Less well understood are processes involving a structural reorganization of articulatory plans due to re-syllabification, e.g., resulting from processes involving massive reduction, epenthesis or metathesis. In this paper, we want to focus on two kinds of re-syllabifications: (1) within-system innovations, in which non-canonical forms occur, and (2) beyond-system inventions, which do not follow the phonotactic constraints of the language under consideration. We examine these processes in a corpus of spontaneous and read dyadic interactions of German, in which time pressure was controlled as an additional factor. Results show that spontaneity and time pressure will mostly lead to within-system innovations, favoring highly trained, unmarked articulatory routines, while minimizing information loss. However, occasionally speakers leave the beaten paths of highly trained articulatory routines, and invent novel phonotactic sequences which are at odds with the phonotactic grammar of German. Our results are discussed in the light of their implications for contemporary models of speech production.
