  • Patent number: 10250744
    Abstract: A call and recorded information management server transmits a requested call identification ID for recognition and an incoming call number corresponding to the ID, to a voice recognition server, which searches for the recognition engine corresponding to the number of the received call, and adds the received ID to a recognition queue. The voice recognition server requests the call and recorded information management server to obtain recorded data by the received ID. The call and recorded information management server transfers the recorded data corresponding to the ID to the voice recognition server to perform voice recognition by the corresponding recognition engine on the recorded data corresponding to the call identification ID stored in the recognition queue, and stores the result as text data. Thus, the most appropriate voice recognition engine can be used and the recognition rate of voice recognition can be increased.

  • Patent number: 10116936
    Abstract: The present invention makes moving-image coding and decoding with low power consumption possible even when a Context-based Adaptive Binary Arithmetic Coding (CABAC) process is used. A preprocess for coding an image is executed for each macro block (MB), the MB information that is the result of the process is written into a storage unit in the order in which the MBs were processed, and the MB information stored in the storage unit is read out in order of raster and the MBs are coded. When the coded image is decoded, the MBs constituting the coded image are decoded in order of raster, the MB information that is the result of the decoded process is stored in the storage unit, and a decoded information readout process that is a post-process for decoding the image is executed in the order in which the MBs were processed.
