Voxento: A Prototype Voice-controlled Interactive Search Engine for Lifelogs

Abstract

In this paper, we describe an interactive voice-based retrieval system for lifelogs which has been developed to participate in the third Lifelog Search Challenge LSC'20, at ACM ICMR'20. Based on a standard text-based retrieval methodology, the novelty of Voxento is in the interactive voice facility that allows a user to interact with a personal lifelog using simple voice commands. Voxento was developed as an initial prototype of a pervasive computing system that can be deployed for wearable technologies such as Google Glass. The version of Voxento described in this paper has been optimised for use with a desktop computer in order to be competitive at the LSC'20 challenge.
