At the Music Hack Day 2011 event in London, Robert Boehnke was able to use SiriProxy to intercept the communication between Apple’s servers and Siri. Siri’s speech synthesis was then synced to the beat using the timestamps obtained from the Echonest API. The speech synthesis was used for the song “Hypnotize” by the Notorious B.I.G. Above is the result. Universal Music awarded him with a pair of Dr. Dre headphones as a reward. [Gizmodo]
