--output-cutset "${manifest_dir}/${synthetic_train_manifest}"
```
This script generates synthetic substitution, insertion, and deletion errors in the transcript with ratios 'sub_er', 'ins_er', and 'del_er', respectively. The original transcript is saved as 'verbatim transcript' in the cutset, along with information on how the transcript is corrupted:
- '[hello]' indicates the original word is substituted by 'hello'
- '[hello]' indicates the original word 'hello' is substituted by another word
- '[]' indicates an extra word is inserted into the transcript
- '-hello-' indicates the word 'hello' is deleted from the transcript
So if the original transcript is "have a nice day" and the synthetic one is "a very good day", the 'verbatim transcript' would be:
```
original: have a nice day
synthetic: a very good day
verbatim: -have- a [] [good] day
verbatim: -have- a [] [nice] day
```
