WTPh? (What the Phonics) is an interactive installation set in the touristic areas of Copenhagen. Street names in Denmark are close to impossible for foreigners to pronounce, so we did a little intervention :-)
More info here:
We recorded a Danish person speaking the street names then split up each syllable. In true karaoke style, we placed lights above the matching syllable so that in real-time, you can see which part of the word is being spoken. When participants lift the speaker off the wall, it starts playing. We used Max/MSP and Arduino to build the installation.
Dan Goodman points out on Twitter that "people from the same country can also need this. Houston St. NYC; Devon Ave. Chicago; Nicollet Ave. Minneapolis…."
[Update: For more, see this post on the Economist's Johnson blog by Robert Lane Greene, who knows a thing or two about the pitfalls of pronouncing Danish.]
