In other words, you could have Siri-like control of virtually any device, with all of the required hardware and software residing on an iPhone or MacBook, linked with other devices over WiFi or Bluetooth. Voice control wouldn't be practical in all situations, but it could be enormously helpful for certain operations, like adjusting settings or reviewing images. Instead of scrolling through hundreds of images, you could simply say "Siri, show me pictures from last Thursday," and see exactly the shots you were searching for. As always, this is one of thousands of Apple patents, and it quite possibly may never come to fruition as described. But here's to hoping it will. "Siri, show our readers the patent application" -- you'll find it at the source link below.
One embodiment may include a first electronic device communicatively coupled to a server and to a second electronic device. The second electronic device may be a portable electronic device, such as a digital media player, that includes a voice user interface. The second electronic device may be capable of accurate speech recognition, but may not include additional computation hardware and/or software for training the speech recognition engine. As such, the bulk, weigh, and cost for manufacturing the second electronic device may be reduced, resulting in a more portable and affordable product.
Update: Well, it looks like we missed the mark a little bit here, as this is a patent application, not a granted patent. It's for a voice control system where a device receives voice commands and turns them into text using a speech-recognition algorithm received from a remote server -- which sounds an awful lot like Siri.
