Standardising SPOKEN Commands for Mobile Devices and Services

摘要

The current state of the art in voice-recognition technology is reaching a level of maturity that suggests sophisticated voice-based user-interface technologies will soon be available in mobile devices. As voice commands for mobile devices and services have so far been primarily limited to voice dialling and the activation of individual menu items, there is currently a window of opportunity to standardise voice commands for basic functions of mobile devices and services. ETSI, the European Telecommunications Standards Institute, has formed a Specialist Task Force (STF) to extend the existing ETSI standard ES 202 076 on voice commands for mobile services and devices. The existing published standard covers five major European languages, whereas the revised version will extend the number of languages covered to 30. This paper gives an overview of the commands and languages covered, and outlines the approach used to identify the voice commands (elicitation, validation and phonetic discrimination).
