+## Regenrate ASR for Dubbing
+
+Create a `regenerate.txt` under the project file, then restart Oryx and refresh the page:
+
+```bash
+touch ./platform/containers/data/dubbing/4830675a-7945-48fe-bed9-72e6fa904a19/regenerate.txt
+```
+
+Oryx will regenerate the ASR and translation, then delete the `regenerate.txt` to make sure it executes one time.
