Voice Recognition (Attempt #1)

Our voice recognition chip arrived! Together with an 8KB SRAM and microphone. We wired the circuit according to the schematic on the website (link: http://www.imagesco.com/speech/sr07schematic.JPG), but unfortunately, nothing seemed to be happening!

There is an LED connected directly to one of the pins on the voice recognition chip (HM2007) that is supposed to light up indicating that the chip is ready for interfacing. This LED was completely unresponsive.
