In this paper we present a flexible and efficient approach to perform an accurate speech recognition interface for isolated command applications in three different languages: Mandarin, Cantonese and English. The paper analyzes and discusses the different trade-offs necessary to obtain an accurate, real-time system with low memory requirements. Areas addressed are design of the training database, and Hidden Markov Model (HMM) units used by the recognizer (monophones versus triphones).
