	CMU Sphinx	CMU Sphinx, also called Sphinx in short, is the general term to describe a group of speech recognition systems developed at Carnegie Mellon University. These include a series of speech recognizers (Sphinx 2 - 4) and an acoustic model trainer (SphinxTrain). In 2000, the Sphinx group at Carnegie Mellon committed to open source several speech recognizer components, including Sphinx 2 and later Sphinx 3 (in 2001). The speech decoders come with acoustic models and sample applications. The available resources include in addition software for acoustic model training, Language model compilation and a public-domain pronunciation dictionary, cmudict.
	Pocket Sphinx	A version of Sphinx that can be used in embedded systems (e.g., based on an ARM processor). Pocket Sphinx is under active development and incorporates features such as fixed-point arithmetic and efficient algorithms for GMM computation.
	iPhone	The iPhone is a line of Internet and multimedia enabled smartphones designed and marketed by Apple Inc. The iPhone functions as a camera phone (also including text messaging and visual voicemail), a portable media player (equivalent to a video iPod), and an Internet client (with e-mail, web browsing, and Wi-Fi connectivity) — using the phone's multi-touch screen to provide a virtual keyboard in lieu of a physical keyboard.
	iPhone OS	iPhone OS (known as OS X or OS X iPhone in its early history) is the operating system for the iPhone, iPad and iPod touch from Apple Inc. Like Mac OS X, from which it was derived, it uses the Darwin foundation. iPhone OS has four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system takes less than 500 Megabytes of the device's total memory storage.
