Industrially oriented voice control system

Abstract

The purpose of my research was to develop a novel voice control system for the use in the robotized manufacturing cells as well as to create tools providing its simple integration into manufacturing. A comprehensive study of existing problems and their possible solutions has been performed. Unlike some other works, it focused on the specific requirements that should be fulfilled by industrially oriented voice control systems. Analysis of existing solutions related to the natural language processing and those related to various voice control applications has been performed. Its goal was to establish the optimal method of voice command analysis for industrially oriented systems. Finally, a voice control system for manufacturing cells has been developed, implemented and practically verified in the laboratory. Unlike many other solutions, it takes into consideration almost all aspects of voice command processing (speech recognition, syntactic and semantic analysis and spontaneous speech effects) and – most importantly – their mutual influence. To provide the simple system customization (integration into any particular manufacturing cells), a special format for quasi-natural sublanguage syntax definition has been developed. A novel algorithm for semantic analysis, using specific features of voice commands used for controlling industrial devices and machines, has been incorporated into the system. Successful implementation in the educational robotized machining cell shows that industrial applications should be possible in the very next future.
