A translation device which has both advantages of a table look-up translation device and advantages of a machine translation device by leading the user's utterance through a sentence template suitable for the user's intent of speech is realized. Since the translation device searches for sentence templates suitable for the user's intent of speech with an orally inputted keyword and displays retrieved sentences, the user's utterance can be lead. In addition, the user is free from a troublesome manipulation for replacing a word since an expression uttered by the user is inserted into a replaceable portion (slot) within the sentence template, and the translation device translates a resulting sentence with the replaced expression embedded in the slot.
