Table 2: The effect on WER when decreasing the latency of the TDS model
['[EMPTY]', '[BOLD] vid-clean', '[BOLD] vid-noisy']
We performed an ablation study to observe the change in WER from the original TDS model [hannun2019TDS] with global input normalization to the low latency version we propose here. We observe that limiting the future context of the acoustic model contributes the most to the degradation in WER.
