Multi-Band Speech Enhancement for Functional MRI

We present an adaptive enhancement method for speech signal corrupted by the 3 Tesla (3T) functional magnetic resonance imaging (fMRI) acoustic noise. The noisy speech signal is filtered into several frequency bands and noise cancellation is applied to each band independently. We use normalized leas...
