A speech recognition server has a speech recognition engine, and a mode control table to hold a speech recognition mode for each call. The speech recognition engine has a mode management unit to designate a speech recognition mode for a decoder, and an output analysis unit to analyze recognition result data speech-to-text converted by speech recognition. The output analysis unit designates the speech recognition mode for the mode management unit in accordance with result of analysis of the recognition result data speech-to-text converted by the speech recognition. The mode management unit designates the speech recognition mode for the decoder in accordance with the designation with the output analysis unit. Upon speech recognition of call data, it is possible to suppress hardware resource consumption while improve users' satisfaction.

Call management system and its speech recognition control method

The present invention relates to a storage apparatus that executes de-duplication processing. Specifically, a storage apparatus includes a storing apparatus configured to provide a first storage area and a second storage area and a control unit. The control unit determines, on the basis of a result of comparison of a compression ratio of compressed data with a threshold, whether first duplication determination for determining whether data same as the data compressed without being stored in the first storage area is stored in the second storage area is executed or second duplication determination for determining whether data same as the data compressed after being stored in the first storage area is stored in the second storage area is executed. Further, the control unit changes the threshold on the basis of a state of the storage apparatus.

Storage apparatus and data management method

In a storage system, a controller prevents the same chunk data from being stored in a storage device in an overlapped manner, on the basis of data block information showing an association of each data block and a plurality of chunk data configuring each data block, chunk group information showing an association of each chunk data not to be overlapped and a chunk group which each chunk data belongs to, and reference data block information showing an association of each chunk group and a data block having any chunk data belonging to each chunk group as constituent elements.

Storage system and storage control method

Deduplicated backup data of a plurality of generations are aggregated and stored. A storage apparatus is connected via a network to a host system making a content write request and includes a storage unit providing one or more containers composed of a specified storage area, and a back up unit storing the content in the container in accordance with a backup request from the host system; and wherein the backup unit cuts out the content into one or more chunks, detects a duplicate chunk, which is a duplicate of a chunk stored in the container, from the cutout chunks, and additionally writes the chunk, other than the duplicate chunk, to the container where the duplicate chunk is stored.
