  • Patent number: 11308158
    Abstract: Provided is an information processing system, including a processor, a storage device and a display device. The storage device stores images captured by imaging devices. If an image of a moving object is selected as a search query, then the processor executes a similarity search on the images stored in the storage device, with the selected image as the search query. The display device displays images attained as results of the similarity search. If an image of a moving object is added as a search query, then the processor executes a similarity search with all selected images as search queries. The display device updates images to be displayed such that images attained as results of the similarity search performed with all the selected images as the search queries are displayed.

  • Patent number: 10074186
    Abstract: An image search system comprising an video taking unit that takes a video, a search unit that contains a processor and a storage unit and searches for an image contained in the video, an input unit that receives information that is input to the search unit, and a display unit that displays information that is output from the search unit. The storage unit holds information indicating the shapes of trajectories that represent the travel paths of a plurality of moving objects extracted from the video. When information indicating the shape of a trajectory is input from the input unit, the search unit searches the plurality of moving-object trajectories held in the storage unit for trajectories that are similar to the input trajectory shape, and if such a trajectory is found, the search unit displays, on the display unit, images of the moving objects that have traveled along the found trajectories.

  • Patent number: 7113909
    Abstract: A stereotypical sentence is synthesized into a voice of an arbitrary speech style. A third party is able to prepare prosody data and a user of a terminal device having a voice synthesizing part can acquire the prosody data. The voice synthesizing method determines a voice-contents identifier to point to a type of voice contents of a stereotypical sentence, prepares a speech style dictionary including speech style and prosody data which correspond to the voice-contents identifier, selects prosody data of the synthesized voice to be generated from the speech style dictionary, and adds the selected prosody data to a voice synthesizer 13 as voice-synthesizer driving data to thereby perform voice synthesis with a specific speech style. Thus, a voice of a stereotypical sentence can be synthesized with an arbitrary speech style.

  • Publication number: 20060004577
    Abstract: In the text-to-speech synthesis technique for synthesizing speech from text, this invention enables a terminal device with relatively small computing power to perform speech synthesis based on optimal unit selection. The text-to-speech synthesis procedure of the present invention involves content generation and output; that is, a secondary content including the results of the optimal unit selection process is output. By virtue of the secondary content, a high load process of selecting optimal units and a light load process of synthesizing speech waveforms can be performed separately. The optimal unit selection process is performed at a server and information for the units to be retrieved from a corpus is sent to the terminal as data for speech synthesis.

  • Publication number: 20020188449
    Abstract: Disclosed is a method which synthesizes a stereotyped sentence into a voice of an arbitrary speech style and which permits a third party to prepare prosody data and permits a user of a terminal device having a voice synthesizing part to acquire the prosody data. The voice synthesizing method determines a voice-contents identifier to point a type of voice contents of a stereotyped sentence, prepares a speech style dictionary 14 including speech style and prosody data which correspond to the voice-contents identifier, selects prosody data of the synthesized voice to be generated from the speech style dictionary 14 by pointing (12) a contents identifier and a speech style for a synthesized voice to be generated (15), and adds the selected prosody data to a voice synthesizer 13 as voice-synthesizer driving data to thereby perform voice synthesis with a specific speech style. A voice of a stereotyped sentence can be synthesized with an arbitrary speech style.

  • Patent number: 6477495
    Abstract: A prosodic parameter for an input text is computed by storing a sentence of vocalized speech in a speech corpus memory, searching for a stored text having a similar prosody to an input text as a key to the speech corpus and modifying the prosodic parameter based upon the search results. Because a plurality of prosodic parameters are handled as a linking data, a synthesized sound similar to natural speech having a natural intonation and prosody is produced.
