LEDs, Speakers, and Raspberries

A project log for Deep Thought

Creating an ominous terminal that responds to voice input with quotes from Hitchhikers Guide to the Galaxy

After lasercutting the wooden body, Cara and I started working on the requirements for the interactive electronics components of the project. We had the following requirements:

We started getting work on exploring localized speech recognition software for the Raspberry Pi (testing on my personal linux box first). We found the pocketsphinx library for python and a good speech recognition wrapper for it. After some initial testing, we realized that we would simply seek out some key words to determine which response to give to the question. Therefore, this isn't very complicated speech recognition, but hey, it gets the job done!

Next up was working with the LED strip. We're envisioning a sort of cyberpunk, gritty Deep Thought and thought having neural pathways lit up with green LEDs would be awesome. We're still in the phase of testing all of this, but we came up with a couple of prototypes for possibilities with the LEDs.
