Voice Command Systems and the Automotive Cockpit

Report: Trends in Voice Command Systems and the In-vehicle Information System

Promise, Constraints and Limitations

Report coming in Fall 2015


Speech recognition is of particular interest within the automotive context because it not only promises to simplify interaction between drivers and the vehicle, but also to mitigate the growing problem of distracted driving. In 2010 alone, the National Highway Traffic Safety Administration (NHTSA) estimated that 3,092 deaths alone were attributable to driver distraction.

This technology scan report finds that there are considerable challenges to realizing the potential benefits of speech recognition within the vehicle cockpit. They include but aren’t limited to technical problems such as noise and cross-talk, engineering challenges such as the integration of multiple modes of driver input to the IVIS (e.g. touch, speech, and gesture), and potentially outdated development processes within the automotive industry. Speech recognition’s potential to alleviate driver distraction is also far from clear, and further research is needed to understand the effects more comprehensively.
