The system recognizes the user’s response and plays the weather report to the caller.

  • Urdu Spoken Dialog System for Location Domain
  • Bus Reservation System is a more advanced spoken dialog system which engages the caller in a question-answer conversation to acquire the desired traveling details that include destination city, departure day, departure time and number of seats. The system uses multiple Automatic Speech Recognition (ASR) systems. After acquiring information from the caller, the system performs a query on the bus schedule database. If there is a bus available, it makes the reservation and informs the user. In case the bus is not available according to the user’s requirements, the system returns two alternative buses and caller is asked to choose one. Then reservation is made in the caller’s chosen bus and the caller is informed about the reservation. Afterwards, a goodbye message is played and the call is terminated. Bus Reservation system is deployed at CLE on PTCL number 042-36821317.
