The research asked whether Mobile GIS incorporating speech recognition was a viable tool for locating defects in the streetscape. The Geography Markup Language for encoding spatial information was used to implement an application schema for street condition surveys. Speech accuracy exceeded 95% in environments that were quiet or constantly loud. However, for tests where the noise level varied, recognition accuracy plummeted to 58%. Accuracy of captured defects was determined while "standing", "walking", "cycling" and "driving". Errors ranged from 0.27m to 12.50m at the 95% confidence interval. A web-based questionnaire indicated that municipal geographic information users are unhappy with the quality of their data, and as yet do not require data in real-time. Future research involves investigating alternative ways of capturing spoken commands, the effect that mobile computing has on the cognitive abilities of the user, and wireless connectivity required for real time access to spatial data.
