Methods of decoding speech from the brain and systems for practicing the same
First Claim
Patent Images
1. A method of decoding speech from the brain of a subject, comprising:
- detecting speech production signals from at least three electrodes directly in contact with the speech motor cortex of a subject while the subject produces or imagines producing a speech sound, wherein the speech motor cortex comprises ventral sensorimotor cortex;
deriving a speech production signal pattern from the detected speech production signals;
correlating the speech production signal pattern with a reference speech production signal pattern corresponding to features of speech associated with at least two speech articulators selected from the group consisting of lips, tongue, larynx, and jaw, to decode speech from the brain of the subject; and
producing the speech decoded from the brain of the subject, wherein the speech is produced in an audible form or in a text form.

Abstract
Provided are methods of decoding speech from the brain of a subject. The methods include detecting speech production signals from electrodes operably coupled to the speech motor cortex of a subject while the subject produces or imagines producing a speech sound. The methods further include deriving a speech production signal pattern from the detected speech production signals, and correlating the speech production signal pattern with a reference speech production signal pattern to decode speech from the brain of the subject. Speech communication systems and devices for practicing the subject methods are also provided.
