This paper presents results from a comparison of text and speech input methods on TravelMan, a multimodal route guidance application for mobile phones. TravelMan provides public transport information in Finland. The application includes a range of input methods, such as speech and predictive text inputs. In this paper we present results from the user evaluation focusing on entry rates of multi-tap text input, domain-specific predictive text input, and speech input. In addition to objective metrics, we present findings about user experiences related to different input methods.
