Voice-controlled Assistance for Robot Navigation Using Android-based Mobile Devices

Abstract

Mobile robotics is an interesting area in which movable objects handle different pre-specified tasks such as line following, object relocation, etc. The advancements in the field of Automatic Speech Recognition (ASR) enable systems to support speech processing capability. This also gives scope to IoT devices that interact with speech dialogue systems. Designing such interfaces is not a straight forward job because of the challenges involved in handling spoken languages. The complexity will increase even more in the context of low resource languages. Adapting language specific features can help in developing such interfaces in IoT environments. In this paper, a speech dialog system is developed for Indian English language to operate robot movements. The system was developed using NXT Lego and Raspberry Pi. The architecture of the system with implementation details are discussed in the paper.
