Innovation and Application of Speech Recognition Technology in Automatic Fare Collection of Rail Transit

摘要

Based on the strategic planning of Shanghai Metro Smart Station and the main problems existing in the Automatic Fare Collection System of rail transit, the application requirements of speech recognition technology in the Automatic Fare Collection System of rail transit are put forward. On the basis of construction background, research and development of key technology points, software and hardware architecture of the scheme and pilot analysis, a voice ticket purchase scheme is proposed. On the basis of the original ticket purchase process of Ticket Vending Machine (TVM), voice recognition technology is used to increase the functions of wake-up-free voice input, Chinese phonetic alphabet input and fuzzy location inquiry, so as to reduce the queue pressure of stations with large passenger flow, improve the efficiency of passenger ticket purchase, and the degree of equipment modernization.
