[Object] An object is to provide an easy-to-use speech processing system attaining higher accuracy of speech recognition.[Solution] Receiving a speech utterance, the speech processing system performs speech recognition and displays a text of the recognition result. Further, the speech processing system translates the recognition result in accordance with settings to a text of another language and displays and synthesizes speech of the translated result. Further, the speech processing system selects utterance candidates having high possibility to be uttered as the next utterance and having high translation and speech recognitions scores, using outputs of various sensors at the time of utterance, a pre-trained utterance sequence model and translation and speech recognition scores of utterance candidates, and recommends utterance candidates in the form of an utterance candidate recommendation list.
