Speech Interface for Internet Service “Yellow Pages”

Abstract

The paper describes new automatic service intended for using telephone directory inquiries without human-operator. We propose to use the automatic speech recognition system for answering the queries of the users. The information about firms and organizations can be taken from the electronic catalogue “Yellow Pages of Saint-Petersburg” located in the Internet and regularly updated with new information. During development such system for Russian language there are sufficient problems, connected with complex structure of word-formation of Russian language. The developed speech recognition system SIRIUS has one additional level of Russian language representation - morphemic level. As a result the size of vocabulary and time for speech processing are significantly decreased. Also the dialogue model for voice control of electronic catalogue “Yellow Pages” is presented in the paper. The first experimental results allow to say about good perspectives of development of telephone speech recognizer for large vocabulary for Russian.
