| Abstract | This paper discusses the advantages and challenges of using speech recognition on mobile devices, for field data collection and real-time communication. Multimodal and voice technology, for speech-enabled information retrieval and input, using mobile phones or handheld computing devices is explained. Multimodal technology enables more complete information communication and supports timely and effective decision-making. It also helps to overcome the limitations imposed by the small screen of mobile devices.<br /><br />The paper describes several prototype, industrial, mobile solutions developed for the field entry of data and real-time communication that utilize voice and multimodal interaction. In one of these projects, a field concrete inspector can enter inspection results using variable interaction modalities such as speech, stylus, or keyboard on a handheld device, or speech-only on a mobile phone. The author describes prototype applications developed, and presents several usage scenarios for field and maintenance applications, as well as for emergency response. |
