An anonymous reader writes "Apple's had a small, very secretive office in Cambridge, MA for a few months now. And we finally know what they're doing: Building a team that works on speech technology for Siri. Sure, it's interesting for Apple to have a remote engineering team. And hiring from MIT is a no-brainer. But here's why this is a bigger deal: Apple has always relied on Nuance, a Boston-area company, for the speech-recognition technology behind Siri. By branching out with its own speech team — stocked with former Nuance scientists, no less — Apple could very well be signaling a move away from relying on Nuance for this core technology. And the speech wars are just heating up: Microsoft and Amazon both have speech engineering offices in the Boston area too."
