title: Dual Causal/Non-Causal Self-Attention for Streaming End-to-End Speech\n Recognition
abstract: Attention-based end-to-end automatic speech recognition (ASR) systems have\nrecently demonstrated state-of-the-art results for numerous tasks. However, the\napplication of self-attention and attention-based encoder-decoder models\nremains challenging for streaming ASR, where each word must be recognized\nshortly after it was spoken. In this work, we present the dual\ncausal/non-causal self-attention (DCN) architecture, which in contrast to\nrestricted self-attention prevents the overall context
