When I record words with LinguaLibre sometimes a recording is not right, so I delete in the step "Publish" of the Wizzard. But then there is no way to redo these recordings then manually writing the down and reselecting them.
Proposal: When recordings are deleted, have a button "redo deleted recordings" that brings the user back to the word-selection and selects all the removed words.
Waiting that this feature be implemented, it is already possible to "delete" a pronunciation during the "Recording" step. To do so, you can simply press the "Del" button, so that the pronunciation is deleted and you can re-record it directly.
That's said, I agree that this shortcut should be documented somewhere.
With the new UX implemented (T240552), you can now listen to records and delete them directly from the studio step, where you can also re-record them. Thereby I think we can consider this task as resolved.
