At a 400 ms delay, SEEG gave a mean 1.7% speech amplitude error decrease beyond 500 ms of sound history on later passages in ten listeners
This exploratory study tested whether SEEG reduced later speech amplitude error beyond a reader using 500 ms of preceding sound. Ten listeners contributed 95 passages, with earlier passages used for fitting and later passages for testing. At a 400 ms SEEG delay, the equal-listener mean relative error decrease was 1.70% (listener bootstrap 95% interval, -3.19% to 6.46%); five listeners improved, three worsened, and two validation procedures omitted SEEG. The data do not show a clear mean benefit under this model and do not establish that SEEG has no benefit. The study concerns heard sound in one reused cohort and does not establish intended speech reconstruction, transfer to another session, live BCI performance, or neural signal origin. Results, figures, models, and MIT-licensed analysis code are retained. Source recordings, annotations, metadata, and extracted input caches are omitted because the source terms conflict; this limits public numerical replay.
