O ver the last decade, our ability to access, store, and consume huge amount of media and information on mobile devices has skyrocketed. While this has allowed people who are on the go to be more entertained, informed, and connected, the small-form factor of mobile devices makes managing all of this content a difficult task. This difficulty is significantly amplified when we consider how many people are using these devices while driving in automobiles and the high risk of driver distraction

A recent government study concluded that drivers performing complex second-ary tasks such as operating or viewing a mobile device or personal digital assistant (PDA) were between 1.7 and 5.5 times more likely to be involved in a crash or near crash [1] . Recognizing the risk posed by the use of mobile devices by drivers, most major car manufacturers have begun selling systems for operating these devices using voice-driven interfaces. Because driving occupies both the user's hands and eyes, voice control has long been proposed as an ideal means of performing in-car tasks. Early in-car systems used voice commands to control many dashboard functions such as the radio, compact disc (CD) player, and climate control. To limit the number of commands active at a time, hierarchical menus were introduced, which put a significant burden on the user to maintain a mental model of the system's menu structure. To alleviate these
