The Semantic Bottleneck: Leveraging Semantic Representations for Non-Invasive Speech Decoding
The semantic bottleneck is a smart shortcut around noisy MEG data: high-level meaning is more robust to extract than phonemes. This matters for brain-computer interfaces and neuroscience but it's far from product readiness. MEG is expensive and the evaluation is on datasets with limited speech diversity. Interesting neuroscience, not actionable for builders yet.
