a Invasive brain signals are acquired through implanted sEEG electrodes. b Multichannel signals are processed to extract the high-gamma power. c Linear decoding models are used to estimate a spectral representation (d) which is synthesized into an audible speech waveform using the Griffin–Lim algorithm and presented to the patient as real-time auditory feedback.
