Speech recognition affords automobile drivers a hands-free, eyes-free method of replying to Short Message Service (SMS) text messages. Although a voice search approach based on template matching has been shown to be more robust to the challenging acoustic environment of automobiles than using dictation, users may have difficulties verifying whether SMS response templates match their intended meaning, especially while driving. Using a high-fidelity driving simulator, we compared dictation for SMS replies versus voice search in increasingly difficult driving conditions. . | Using Speech to Reply to SMS Messages While Driving An In-Car Simulator User Study Yun-Cheng Ju Tim Paek Microsoft Research Redmond WA USA yuncj timpaek @ Abstract Speech recognition affords automobile drivers a hands-free eyes-free method of replying to Short Message Service SMS text messages. Although a voice search approach based on template matching has been shown to be more robust to the challenging acoustic environment of automobiles than using dictation users may have difficulties verifying whether SMS response templates match their intended meaning especially while driving. Using a high-fidelity driving simulator we compared dictation for SMS replies versus voice search in increasingly difficult driving conditions. Although the two approaches did not differ in terms of driving performance measures users made about six times more errors on average using dictation than voice search. 1 Introduction Users love Short Message Service SMS text messaging so much so that 3 trillion SMS messages are expected to have been sent in 2009 alone Stross 2008 . Because research has shown that SMS messaging while driving results in 35 slower reaction time than being intoxicated Reed Robbins 2008 campaigns have been launched by states governments and even cell phone carriers to discourage and ban SMS messaging while driving DOT 2009 . Yet automobile manufacturers have started to offer infotainment systems such as the Ford Sync which feature the ability to listen to incoming SMS messages using text-to-speech TTS . Automatic speech recognition ASR affords users a hands-free eyes-free method of replying to SMS messages. However to date manufacturers have not established a safe and reliable method of leveraging ASR though some researchers have begun to explore techniques. In previous research Ju Paek 2009 we examined three ASR approaches to replying to SMS messages dictation using a language model trained on SMS responses canned responses using a probabilistic .
