Before revision:  For the diversity of temporal resolution in embedding processing, we consider dilation on TDNN-F, a variant of 1D-CNN .  Each stream stacks narrower TDNN-F layers whose kernel has a unique, stream-specific dilation rate when processing input speech frames in parallel.
After revision:  For the diversity of temporal resolution in embedding processing, we consider dilation on TDNN-F, a variant of 1D-CNN . The dilation rates are selected from the multiples of a sub-sampling rate of 3 frames. Each stream stacks narrower TDNN-F layers whose kernel has a unique, stream-specific dilation rate when processing input speech frames in parallel.
