 # DeepSpeech2 ONNX model
 
-1. convert ds2 model to ONNX, using Paddle2ONNX.
+1. convert deepspeech2 model to ONNX, using Paddle2ONNX.
 2. check paddleinference and onnxruntime output equal.
+3. optimize onnx model
+4. check paddleinference and optimized onnxruntime output equal.
+
+Please make sure [Paddle2ONNX](https://github.com/PaddlePaddle/Paddle2ONNX) and [onnx-simplifier](https://github.com/zh794390558/onnx-simplifier/tree/dyn_time_shape) version is correct.
