It's tough to show a 3-D circuit with just a couple pix. 
What you're asking for only needs the 3 components - RTC, Memory Bank and A>D. Outputs 2 and 3 (minutes and hours) from the RTC go to the Bank inputs and the Bank output goes to the A>D input. (Like a quick description is soooo much better! haha)
If that doesn't help, I can make a world and give you a link.
The actual hard part is making sure to get the program right. If you understand the Memory Bank well and have a good grasp or binary logic, you canmfigure it out. If you need more help. I can program one for the world but that will take me a bit longer.

You must also be aware that you have to be close enough to 'hear' the signs speak. Electrics only work when within the view distance so if you're farther away than that, the circuit won't work and signs won't speak!
