Evaluating regular and speech-based text entry for creation of smartphone based addresses

Abstract: Billions of people on earth lack a home address. In this paper we are investigating an approach to solve this using an address system where addresses consists of a GPS location and a description of how you find your way to the house when you are within close distance to the GPS location. The aim of the paper is to measure if said description has higher quality when it’s given using speech-based or regular text entry. Our findings indicate that speech based text input gives 1.7 times more information in about 5.5 times less time. From a usability standpoint there was no indicated difference, but as the experiments were carried out during perfect conditions it is concluded that speech-based text entry would likely present more of a challenge for the users. When and if speech recognition is more widely adopted into systems for everyday use, speech-based text entry will be a good asset for increasing the amount of information collected from users in navigational contexts.
