Abstract

We propose an interface for a name input based on speech recognition using a word dictionary and syllable-based N-gram. User first utters a name and then chooses the correct word/syllables by touch input from word/syllable candidates which were obtained from speech recognition. Name utterance is hard to recognize accurately because of the large vocabulary size, so the system uses isolated word recognition with a dictionary containing high frequent words and continuous syllable recognition with syllable-based N-gram. System displays word candidates, syllable sequence candidates and a syllable lattice on the touch panel. Users who were familiar to speech input could find the correct answer from word candidates or syllable sequence candidates at a rate of 87-92%, and they felt that it was useful. Novice users also obtain the same level of accurate candidates after 30-40 minutes' practice and the interface became useful to them.
