Single slice RT-MRI acquisition aligned with a simultaneous acquired audio of speech after acoustic gradient noise cancellation: The speech task was the phrase “bright sunshine shimmers across the ocean” at the subject's normal pace. This phrase contains several consonant clusters and fricatives, which involve fast articulatory movements. For instance, the time window highlighted by the red arrow depicts the formation of the consonant cluster [kr], where the tongue retracts back, and then touches the hard palate. The bottom row shows every fourth frame (for compactness) of the reconstructions to depict the articulatory movement during this sound. Note the constrained reconstruction based images show less motion blur and loss of temporal fidelity in comparison to view-sharing (see yellow arrows).
