Researchers have developed a new temporal convolutional decoder called NOEMA to reconstruct perceived speech from functional magnetic resonance imaging (fMRI) data. This decoder aligns windows of fMRI measurements with multimodal stimulus embeddings, which combine text, audio, and speech representations. NOEMA demonstrated a significant improvement over baseline decoders in retrieving correct speech segments from brain activity, successfully identifying the correct segment among 2,000 candidates within the top 10 for over 42% of queries on two naturalistic speech datasets.
