Abstract
Methods and systems are disclosed for training a machine learning (ML) model to detect inner speech. The system collects, by an electromyograph (EMG) communication device used by a user, a first set of EMG signals over a first time interval. The system generates a first plurality of features based on the first set of EMG signals and generates a first probability associated with presence of inner speech by processing the first plurality of features with a machine learning (ML) model. The system compares the first probability generated by the ML model to a specified threshold and detects presence of the inner speech of the user in response to determining that the first probability generated by the ML model transgresses the specified threshold.
