Web2. Conformer Encoder Our audio encoder ﬁrst processes the input with a convolution subsampling layer and then with a number of conformer blocks, as illustrated in Figure 1. The distinctive feature of our model is the use of Conformer blocks in the place of Transformer blocks as in [7, 19]. A conformer block is composed of four modules stacked Web模型包含三个部分，分别为共享的Encoder、CTC解码器、Attention解码器；共享Encoder包含多层transformer或者conformer；（encoder-conformer layers are particularly modified.—改成了causal convolution） CTC解码器为一个全连接层和一个softmax层； Attention解码器包含多层transformer层。
