Speech Recognition Using Finger Tapping Timings
Behavioral synchronization between speech and finger tapping provides a novel approach to improving speech recognition accuracy. We combine a sequence of finger tapping timings recorded alongside an utterance using two distinct methods: in the first method, HMM state transition probabilities at the word boundaries are controlled by the timing of the finger tapping; in the second, the probabilit...
متن کاملWhole-brain functional MR imaging activation from a finger-tapping task examined with independent component analysis.
BACKGROUND AND PURPOSE Independent component analysis (ICA), unlike other methods for processing functional MR (fMR) imaging data, requires no a priori assumptions about the hemodynamic response to the task. The purpose of this study was to analyze the temporal characteristics and the spatial mapping of the independent components identified by ICA when the subject performs a finger-tapping task...
متن کاملAbbreviating the Finger Tapping Test.
The Finger Tapping Test (FTT) has a strong empirical base but its procedures are inconsistent and the test can be time-consuming. To simplify and abbreviate administration procedures, several potential abbreviated procedures were evaluated using a sample of 71 individuals presenting to a VA Hospital for neuropsychological evaluation. A short version using the mean score of Trials 3-5 for each h...

متن کاملLobular patterns of cerebellar activation in verbal working-memory and finger-tapping tasks as revealed by functional MRI.
The lobular distributions of functional activation of the cerebellum during verbal working-memory and finger movement tasks were investigated using functional magnetic resonance imaging (fMRI). Relative to a rest control, finger tapping of the right hand produced ipsilateral-increased activation in HIV/HV [Roman numeral designations based on Larsell's () nomenclature] and HVI and weaker activat...
