Researchers have developed NeuroSonic, a new framework for reconstructing speech from electroencephalography (EEG) signals. This method utilizes conditional flow matching to learn a deterministic velocity field that transforms noisy acoustic states into clear speech, guided by EEG data. NeuroSonic addresses the challenges of EEG's weak and variable signals by embedding EEG and audio into a shared token space and employing a time-conditioned Transformer. Evaluations on the CineBrain and EAV benchmarks show NeuroSonic outperforms existing GAN, diffusion, and mean-flow models, particularly in artifact-heavy segments, by improving distributional realism, spectral fidelity, and perceptual quality.
