| - The **Beam Search Decoder** for DS2 CTC-trained network follows the similar approach in \[[3](#references)\] with a modification for the ambiguous part, as shown in Figure 2. | ||
| - An **external defined scorer** would be passed into the decoder to evaluate a candidate prefix during decoding whenever a space character appended. |

What is the ambiguous part and what is the modification? Could you please add more details?

- --> any other custom scorers.
- What do you mean by "a unified class"?
- Remove "may".
