The present invention provides a dialogue supporting apparatus that can easily select a desired sample sentence from among candidate-sample sentences corresponding to inputted speech. The dialogue supporting apparatus includes: a speech recognition unit which performs continuous speech recognition of the inputted speech; a database unit having a sample sentence database which holds the correspondence of sample sentences of a source language and a target language; a sample sentence selection unit which selects one or more sample sentences from within the sample sentence database, according to a speech recognition result or operation of a GUI unit; a sample sentence comparison unit which (i) compares the one or more sample sentences selected by the sample sentence selection unit and the speech recognition result, (ii) calculates word scores from an appearance location of the words, and (iii) derives a display parameter for each word of each sample sentence, based on the word scores; and the GUI unit which performs the display of a sample sentence based on the display parameter.
