A Mandarin speech recognition prototype system for telephone number inquiry is implemented on a PC platform with a Dialogic D/41D card and a 16-bit Soundblaster card as the telephone line interface. It is an integration of a speaker-independent, isolated-word speech recognition sub-system and a text-to-speech subsystem and operates under Windows 95. It uses the Hidden Markov Model technique and chooses 100 final-dependent initials and 39 finals as basic recognition units. The vocabulary to be recognized are made of 1922 names of bank and insurance companies with word lengths ranging from 2 to 14 syllables. A recognition rate of 92.6% is achieved and all output messages are responded by the TTS sub-system.
