| Outline of Final Research Achievements |
Subword recognition is performed for speech data streams, and we developed the new method to construct an index of syllable bigrams. When a user input query keywords, the method first selects a limited number of utterances including bigrams in query keywords, and enables to quickly identify the sections where query keywords are spoken in spoken documents
We also developed the method to search similar images quickly for a large amount of images and video data using Particle Swarm Optimization (PSO), and demonstrated the possibility of both directional search by the prototype system, "Searching/detecting an object using a speech"
