SPEECH RECOGNITION DEVICE AND NAVIGATION DEVICE

摘要

A speech recognition dictionary is created for words extracted from address data which is a lexicon subject to speech recognition, said extracted words having a frequency of appearance greater than or equal to a prescribed value. The speech recognition dictionary is compared with a time series of acoustic features of inputted speech, and a word string which is the most likely candidate for the inputted speech is identified from the speech recognition dictionary. The identified word string and the address data are compared for partial matches, and a partially matching term is treated as a speech recognition result.
