Automatic speech recognition (ASR) systems for real-life scenarios are required to process audio streams of arbitrary length with stable accuracy under limited computational resources. While the joint connectionist temporal classification (CTC) and attention-based encoder-decoder (AED) model delivers high recognition quality, its vanilla form is unable to meet these requirements. This paper proposes an input-synchronous blockwise decoding algorithm for the joint CTC-AED model. The algorithm proc
