How to recover deleted voice memos

You linked from an iCloud backup article, so are you asking how to recover them from an iCloud backup? If so, then you would have to erase your device, and then restore it to an iCloud backup that you made after the voice memo was created, but before you deleted it. Be aware that restoring your device to a backup will put your device in the exact same place it was at the time the backup was made. Any changes since that time would be overlaid by the backup:
