<p>Voice signal being a broadcast itself transmitted from a broadcast station is stored along with language data based on the broadcast. Thereafter, the voice signal is reproduced (S215) for a user to listen to the reproduced voice signal. The user determines validity or invalidity of the voice signal; a result of the determination is retrieved (S220). When the user determines the validity of the voice signal, mark data indicating validity is attached to the language data corresponding to the voice signal (S230); by contrast, when the user determines the invalidity of the voice signal, the voice signal and corresponding language data are deleted (S235). As a result, the language data with the mark data is regarded as being necessary for the user, so that availability of the language data is enhanced. <IMAGE></p> |
