1. A communication support apparatus comprising: a processing system comprising at least one processor; and a memory comprising one or more tangible computer-readable media containing instructions for execution by the processing system, wherein the instructions, when executed by the processing system, programmatically define: a speech recognizer that recognizes a first speech of a source language as a first source language sentence, and recognizes a second speech of the source language following the first speech as a second source language sentence; a determining unit that determines whether the second source language sentence is similar to the first source language sentence; and a language converter that translates the first source language sentence into a first translation sentence, and translates the second source language sentence into a second translation sentence different from the first translation sentence when the determining unit determines that the second language sentence is similar to the first source language sentence.

The communication support apparatus according to claim 1 , wherein the instructions further programmatically define: a source language analyzer that analyzes a meaning of the first source language to output at least one first analysis result, and analyzes a meaning of the second source language to output at least one second analysis result, wherein when the determining unit determines that the second source language sentence is similar to the first source language sentence, the language converter outputs at least one first translation word candidate indicating the same meaning as the first source language sentence based on the first analysis result, outputs at least one second translation word candidate indicating the same meaning as the second source language sentence based on the second analysis result, selects one of the at least first translation word candidate, selects one of the at least second translation word candidate different from the one of the at least one first translation word candidate, translates the first source language sentence into the first translation sentence based on the first translation word candidate selected, and translates the second source language sentence into the second translation sentence based on the second translation word candidate selected.
