5th International Conference on Spoken Language Processing
This paper describes the development of a Korean address entry/retrieval system using bimodal input; speech recognition and touch sensitive display. The system works on a personal computer and employs automatic speech recognition and touch sensitive display techniques as user interface for input Korean address, which consisted with about 40,000 words. To meet the needs that practical speech recognition system should be worked in real time without any degradation of performance of recognition accuracy, 1)speaker and environmental adaptation by Maximum a posteriori(MAP) estimation were adopted for higher recognition and 2)fast search by tree-structured lexicon and frame synchronous beam search technique were employed for real time response. To offer more convenient user interface, touch sensitive display is also implemented. As the results, the system worked in 3 seconds after completion of address utterance with sentence recognition accuracy of above 96%.
