Comparison of mean latency, speedup, complexity in AT, NAT and PSAT on RWTH-PHOENIX-Weather-2014T.

Approach	Mean Latency (ms)	Speedup	Complexity
AT	387	1×	$L\left(O\right(ts)+O(gs\left)\right)$
NAT	21	18.4×	$O\left(ts\right)+O\left(gs\right)$
PSAT	108	3.60×	$\frac{LN}{\sum d^{*}}(O\left(ts\right)+O\left(gs\right))$
