Subjects

For those affected by disorders or injuries that impair speech, technologies that can accurately and rapidly decode brain activity to facilitate natural communication could be transformative. Two papers now report the development of brain–computer interfaces that enable speech to be decoded from cortical activity with previously unreachable levels of precision and speed.

Previous studies have demonstrated that speech-related activity in the sensorimotor cortex (SMC) can be decoded in individuals who are unable to produce intelligible speech; however, currently available speech decoders and alternative communication technologies are limited by their speed, accuracy, vocabulary size and modality of output (typically text-only). The advances reported by Willett et al. and Metzger et al. now offer solutions to these problems.
