Referred to as statistical learning (SL), this process is particularly critical when learning a spoken language, helping in the identification of discrete words within a spoken phrase. Here, by considering individual differences in speech auditory-motor synchronization, we demonstrate that recruitment of a specific neural network supports behavioral differences in SL from speech. While independent component analysis (ICA) of fMRI data revealed that a network of auditory and superior pre/motor regions is universally activated in the process of learning, a frontoparietal network is additionally and selectively engaged by only some individuals (high auditory-motor synchronizers). Importantly, activation of this frontoparietal network is related to a boost in learning performance, and interference with this network via articulatory suppression (AS; i.e., producing irrelevant speech during learning) normalizes performance across the entire sample. Our work provides novel insights on SL from speech and reconciles previous contrasting findings. These findings also highlight a more general need to factor in fundamental individual differences for a precise characterization of cognitive phenomena.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Brain MappingHumansMagnetic Resonance ImagingSpeechSpeech Perceptionresearch article35793349open access10.1371/journal.pbio.30017121545-7885PMC9292101https://journals.plos.org/plosbiology/article/file?id=10.1371/journal.pbio.3001712&type=printablehttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC9292101/pdf
