1. A speech translation apparatus comprising: a correspondence storage unit that stores identifiers to uniquely identify each of a plurality of terminals connectable via a network and usage languages used in the terminals associated with each other; a receiving unit that receives a source speech from one of the terminals; a translating unit that acquires the usage languages different from a source language used in the source speech from the correspondence storage unit, and generates a translated speech translated from the source speech by using each of the acquired usage languages as a target language; a determining unit that determines whether the translated speech has been generated in all of the target languages when the translated speech is generated in any one of the target languages; an output unit that outputs the translated speech when the translated speech has been generated in all of the target languages; and a sending unit that sends the translated speech to each of the terminals identified by the identifier corresponding to the target language.

The apparatus according to claim 1 , wherein the determining unit determines whether a first speech duration and a second speech duration of the translated language have been generated in all of the target languages, when the translated speech is generated in any one of the target languages, the first speech duration being a duration to be output next in one of the target languages and the second speech duration being a duration to be output in any other target language before an end of the first speech duration, and the output unit outputs the translated speech and the source speech that correspond to the first speech duration and the second speech duration, when the first speech duration and a second speech duration of the translated speech have been generated in all of the target languages.
