Think about a creating a car which would be controlled by your voice. By giving a command, the car would drive you to your destination. The voice recognition algorithm we used could be applied to daily life; for example it would be most helpful to disabled people to perform their daily work. We created a speech controlled car using various electrical and mechanical domains such as digital signal processing, analog circuit design, and interfacing the car with the Mega32.

High Level Design


Rationale and sources of your project idea:
We were both interested in building some kind of robot. We researched projects that had been done in the field of robotics and there existed a line follower robot, and sensor robots but none of them used speech to control a robot. In the digital world, it would be cool to make a robot which obeys human speech commands and performs errands. In the movie “I, Robot”, (where our project idea came from) they showed a high tech robotic car responding to vocal commands and driving according to human speech. We picked a part of the theme of the movie to make a car move using speech recognition. The required computation to process speech would normally overflow the mega32 memory, but we found a nice algorithm from a website by Tor Aamodt, from the ECE department at the University of British Columbia that would fit within our constraint.
