In par- allel it can be assumed that a repository exists for motor representations of the most frequent syllables of a speakers language in order not to burden the brain with “compiling” or “online assembling” a motor plan in real time for each syl- lable during speech production (concept of mental syllabary, see Levelt & Wheeldon 1994, Cholin et al. 2006). Over the last decade we have computer-simulated the knowledge or skill acqui- sition needed for the built up of such a mental syllabary. This knowledge or skill acquisition occurs during the first years of speech and language learning (Kröger et al. 2009 and 2011). A computer simulation of speaking skill acquisition first...
