Neurolinguistic and machine-learning perspectives on direct speech BCIs for restoration of naturalistic communication

Abstract: a GrK 1624 'frequency effects in language' , university of freiburg, ABSTRACT The ultimate goal of brain-computer-interface (BCI) research on speech restoration is to develop devices which will be able to reconstruct spontaneous, naturally spoken language from the underlying neuronal signals. From this it follows that thorough understanding of brain activity and its functional dynamics during real-world speech will be required. Here, we review current developments in intracranial neurolinguistic and BCI res… Show more

“…Neurolinguistics research is providing insight into the cognitive function, phenomenology, and neurobiology of speech production in general ( Hickok, 2014 ) and imagined speech in particular ( Alderson-Day and Fernyhough, 2015 , Perrone-Bertolotti et al., 2014 ), and it is our view that these insights should be utilized within DS-BCI research. We concur with the arguments expressed by Iljina et al. (2017) that, given the complexity of speech production processes, combining research from the fields of BCI and neurolinguistics must be seen as an important approach for those seeking to capture and decode the phenomena.…”

“…The importance of consistency in the way imagined speech is produced by experimental participants and the effect of providing them with a thorough understanding of what is meant by imagined speech production are additional areas for investigation that may improve the robustness of experimentation. In the following subsections, we extend the work of Iljina et al. (2017) by highlighting three key areas where BCI research can benefit from findings in the field of neurolinguistics.…”

“…Instead of using isolated phonemes or syllables, we collected neural data during the imagination and production of phrases (e.g., how are you? ), with the eventual goal of open-vocabulary decoding (decoding phonemes within phrases) for naturalistic communication (Iljina et al, 2017). Here, we classified whole phrases, as a starting point.…”
