Abstract: A conventional speech recognition dictionary, translation dictionary and speech synthesis dictionary used in speech translation have inconsistencies.

Abstract: Appropriate processing results or appropriate apparatuses can be selected with a control device that selects the most probable speech recognition result by using speech recognition scores received with speech recognition results from two or more speech recognition apparatuses; sends the selected speech recognition result to two or more translation apparatuses respectively; selects the most probable translation result by using translation scores received with translation results from the two or more translation apparatuses; sends the selected translation result to two or more speech synthesis apparatuses respectively; receives a speech synthesis processing result including a speech synthesis result and a speech synthesis score from each of the two or more speech synthesis apparatuses; selects the most probable speech synthesis result by using the scores; and sends the selected speech synthesis result to a second terminal apparatus.

Abstract: In conventional network-type speech translation systems, devices or models for recognizing or synthesizing speech cannot be changed in accordance with speakers' attributes, and therefore, accuracy is reduced or inappropriate output occurs in each process of speech recognition, translation, and speech synthesis. Accuracy of each processing of speech translation, translation, or speech synthesis is improved and appropriate output is performed in a network-type speech translation system by, based on speaker attributes, appropriately changing the server to perform speech recognition or the speech recognition model, appropriately changing the translation server to perform translation or the translation model, or appropriately changing the speech synthesis server or speech synthesis model.
