Generation history allows you to listen to, download and restore previous audio generations for each paragraph.
From your generation history, you can see all the previous generations for the selected paragraph.
You can listen to all your previous generations, and if you prefer an earlier generation, you can restore this by clicking "Restore". This audio will then appear as the current version of the paragraph in your Project. You can use the lock button to lock the paragraph to prevent further changes.
For each generation, you can download the individual audio file.
You can also remove generations, but please bear in mind that removing a generation is permanent, and it cannot be recovered.
