I dictate SQL using speech recognition, and lining things up is a pain. If I could see where the tab stops are it would save me a lot of time.
Perhaps SQL Refactor by Red Gate. You can define the desired layout of the code, and then simply use command "Lay Out SQL".
When you install SQL Refactor it adds extra menu item to the Management Studio main menu. Each command has its keyboard shortcut (e.g. for Lay Out SQL it is Ctrl+B Ctrl+L) so I assume you should be able to assign that command to your speech recognition tool.
SQL Refactor comes with the price but you can be download 14-day full working trial to try it it serves your needs.
