Flexible rhythm production abilities and cortical tracking of speech in the healthy and damaged brain

Project description

Listening to the rhythm of speech

Rhythm is a key element of speech, often overlooked in language tests. While keeping a steady beat is seen as important, natural conversation rarely follows perfect timing. Supported by the Marie Skłodowska-Curie Actions programme, the FlexyRhythm project argues that true language skill lies in what we can do, not just what we know. It is developing a new test and using brain imaging to explore how flexible rhythm abilities relate to language learning – both native and second language learning – and speech recovery after stroke. By studying how the brain links sound and movement, FlexyRhythm aims to improve language teaching methods and therapies for speech and language disorders.

Objective

FlexyRhythm aims to move beyond traditional assessments of rhythmic abilities in the speech domain by proposing the strong hypothesis that synchronizing to isochronous speech is necessary but not sufficient for developing language abilities. In addition to this, the ability to flexibly reproduce and synchronize to slightly irregular rhythms typical of natural speech is crucial for enhancing the brain’s capacity to track continuous speech in naturalistic contexts. The project will develop a novel test to assess these abilities and investigate the relationship between flexible rhythm production abilities and key aspects of the human speaking brain, including: (i) statistical learning as a proxy for language acquisition, (ii) native language processing, (iii) second language learning, and (iv) speech-motor and language deficits following stroke. By employing magnetoencephalography (MEG) and state-of-the-art analytical tools such as temporal response function, coherence, and transfer entropy, the project will objectively assess the human brain's capacity to track and encode acoustic and linguistic information during speech listening (cortical tracking of speech), the neural auditory-motor connectivity dynamics underlying tracking, and the relation with flexible rhythm production abilities. FlexyRhythm offers a comprehensive exploration of the interplay between rhythm and speech, advancing our understanding in both healthy and damaged brains, across native and second language learning. The findings will provide scientific insights and societal benefits, including improved language teaching methodologies and personalized healthcare strategies for acquired speech and language disorders.
