Embodied speech: sensorimotor contributions to native and non-native language processing and learning

Résumé

The last 15 years of research on language production and comprehension have put forward a conceptual revolution, highlighting how language may depend not only on specific brain areas but also on embodied processes underpinned by sensorimotor brain regions. A large amount of studies have underlined the sensorimotor grounding of the different processes at play in language comprehension, in particular action verb processing and sentence comprehension (see Fischer & Zwaan, 2008 and Franken et al., 2022 for reviews). One aspect of language processing, phoneme perception, has been less extensively studied in light of embodied cognition, yet the motor involvement in decoding sounds pertaining to a linguistic code seems to play a crucial contribution. The focus of the current review is to provide an updated overview of the findings in this domain on both native (Sections I and II) and foreign (i.e. non-native) phoneme perception (Section III), and to further examine if and how motor training may enhance phonological processing and learning of foreign language speech sounds (Section IV and V).

I. Motor resonance to native speech perception

Neuroimaging studies using Transcranial Magnetic Stimulation (TMS) or functional Magnetic Resonance Imaging (fMRI) have provided compelling evidence that (pre)motor regions involved in speech production are also activated during the mere perception of native phonemes. In their seminal work, Fadiga and colleagues (2002) applied TMS to the left motor cortex of Italian adults while they listened to words and pseudo-words featuring either the double lingua-palatal fricative (alveolar trill) /rr/, which requires strong tongue tip movements to be produced, or the double labiodental fricative /ff/, which only involves minor tongue
