The common sound term gave 99% of mean error correlation for nine fixed 400 ms SEEG readers on 25 shared passages
We tested error agreement between fixed SEEG sound amplitude readers. The source was public OpenNeuro ds004703 version 1.1.0. Nine people supplied 89 later records of 25 shared sound passages. These records gave 129 comparisons from 18 different person pairs. Each sound had equal weight. At 400 ms delay, mean paired error correlation was 0.8088. An exact common-target term contributed 0.8018, or 99.1% of that mean. After linear amplitude projection, mean residual correlation was 0.0822. Its descriptive 95% sound bootstrap interval was 0.0230 to 0.1437. The remaining mean stayed positive after removal of each sound or person. The target projection used test labels for diagnosis. It did not change any reader. This result supports a target control before shared readout errors are given a neural interpretation. The tested scope was heard speech in the same recording context. The package preserves selected neural features, fixed models, predictions, an exact proof, code, three figures, source range receipts, and repeat instructions. Independent calculations checked all 23,400 predictions. Fresh checks matched nine pinned SEEG ranges and short samples from 36 sound files. This study does not test live control, intended speech, or stimulation.

This study uses the unchanged fixed readers, selected SEEG features, sound targets, and later predictions from this publication. It adds matched cross-person error scores and an exact common-target control. No reader is selected or fitted with these error scores.

The study uses SEEG recordings and heard-speech targets from OpenNeuro ds004703 v1.1.0. The source release README also states noncommercial and no-identification limits; those limits conflict with the CC0 metadata, so source-derived feature caches and source metadata are omitted.
