Abstract

A real-time speech recognition system of Italian has been developed at IBM Rome Scientific Center. It handles natural language sentences from a 20000-word dictionary, dictated with words separated by short pauses. The architecture consists of a PC/AT equipped with signal processing hardware. The paper describes the system, shows results of decoding tests and includes descriptions of the topics in speech recognition being currently investigated.
