EEG-to-Text Moves Up to the Sentence
A hierarchical alignment framework studies whether inexpensive non-invasive EEG can retrieve a read sentence using both brain signals and linguistic context.
Summary
A hierarchical alignment framework studies whether inexpensive non-invasive EEG can retrieve a read sentence using both brain signals and linguistic context.
Brain-to-text work has often relied on expensive fMRI or MEG, while EEG studies concentrate on phonemes, letters and words. This paper turns to sentence-level retrieval, arguing that sentence meaning can survive missing lower-level detail and that classification deserves separate study from free-form generation. Its hierarchical alignment framework combines EEG with context to retrieve the sentence a participant read and investigates how brain signals align with text at several representational levels. The abstract frames the work as an investigation rather than a clinical communication system and does not support claims that imagined speech has been decoded or that the method is ready for people with locked-in syndrome.
