Man, this brings back memories of playing with Festival back in the day. I wrote a bunch of scripts to generate dynamic Festival text2speech audio for a Part15 AM radio station, a virtual radio station DJ over 15 years ago. The intelligibility was not great back then, the funny thing was after spending many hours listening and tweaking my input text I trained myself to understand the default voice a lot better. Other people had a hard time with the default voice but I could understand it perfectly. Thankfully some of the improved voices available back then helped it a lot.
To fix pronunciation problems I had developed a set of domain-specific "dictionaries", sed substitution scripts that would translate certain words and phrases into their phonetic versions that would be pronounced better by Festival. Besides announcing the names of songs being played, I was also feeding news articles and some other web-scraped info through it. Tons of fun to hear your project working on the air in public as you drive around town.
Ohm lordy, we're blaming the student for not having years of homebrew experience before he entered school? Sure any hobbiest knows what a 555 is, but when the lab assistant doesn't even catch it and the chip was handed out to the student this is not an entry-level students fault.
Regardless of what the real story is on this van, lookup the Bernie S. case if you want an easy case with proof of government surveillance incompetence. Under cover Secret Service agents were photographed surveilling a 2600 meeting in a mall court, then got embarrassed when the 2600 guys posted flyers with their photographs around. Most criminals are dumb which is a good thing as I like the bad guys getting caught, but unfortunately the smart ones graduate to become politicians.
Ah yes, memories of my laptop, an Orinoco card, and Netstumbler cruising down the highway during my day-job. Shortly after that I added an X-10 video receiver and a USB Hauppauge WinTV adapter to capture video transmitters too. I'd reach over and trigger a screen-shot whenever live video came into view. Once in a while I'd even capture myself driving through a parking lot or something on the feed.
I think this was the plot of an episode of CSI (don't recall which sub-series, maby Miami?) in the 2000's. Eventually they determine a guy dies of lead poisoning and they figure out he ate massive amounts of chocolate candy. Conclusion: leaded gas used in other countries caused lead buildup on coco plants there and eventually gets shipped back to US chocolate makers.
