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.
