How Jasper and QuartzNet process residual connections ?

[Arsham-boredom]

• first time here, not sure if this is right place to ask.

To proceed Residual connection, each SubBlock output tensor add to residual tensor, which has 1x1Conv followed by BatchNorm.

these tensors need to be singleton, any mismatch in their shape will raise "mismatch" error.

in resnet, inputs get resized to some fixed size (32x32 for example) and kernel and strides are computed manually so block outputs and residual have same tensor shape.

here is my question, ASR models' inputs may vary in sequence length (5s up to 25s), they are NOT fixed.

how these models handle residual connection in this case?
