Abstract: An operation support apparatus includes: an acquisition unit that acquires an operation status of transportation means; a generation unit that performs processing of recognizing voices of a first staff who gives an instruction to operate the transportation means and a second staff who is instructed by the first staff, and generates character information obtained by converting the recognized voice into characters; a detection unit that performs syntax analysis on the character information and detects wrong recognition by the first or second staff; and a display control unit that displays the character information and the detection result of the wrong recognition by the detection unit on a display device visually recognizable by the first staff, thereby reducing occurrence of an accident due to the wrong recognition by the staff related to operation of the transportation means at a site where the transportation means is operated.

Abstract: Voice data that can be input in a plurality of languages is accurately recognized. An identification unit identifies a language of voice data that has been input, and a recognition unit converts the voice data into that has been input, into character string data by using a voice recognition engine relevant to the language that has been identified among a plurality of voice recognition engines related to different languages.

Abstract: An apparatus that can make a success of demodulation on the reception side even if the restrictions on the resource setting are lifted. The apparatus includes: a processing unit configured to variably set at least any of a number of subcarriers or a number of subsymbols included in a unit resource including one or more subcarriers or one or more subsymbols, and set a filter coefficient that is applied in accordance with different rules which depend on whether the number of subsymbols included in the unit resource is an even number or an odd number.
