Before revision:  The proposed architecture accommodates diverse temporal resolutions in multiple streams to achieve robustness in acoustic modeling. 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.
