A speech synthesis device detects beta peak firings corresponding to intended vocalizations by a subject having a scalp, a mastoid process and a speech motor cortex. A EEG electrode and a negative electrode are disposed on the scalp of the subject adjacent to the speech motor cortex. A transmitter is electrically coupled to the electrodes, and is configured to transmit wirelessly electronic representations of the neural potentials detected by the electrodes. A remote unit receives the electronic representations of the neural potentials from the transmitter. The remote unit is programmed to: detect beta peaks firings in the neural potentials; correlate the beta peaks firings with beta peaks associated with phonemes, words and phrases; and generate audible representations of the phonemes, words and phrases.
