A voice input section receives voice of the user designating a name etc. and outputs a voice signal to a speech recognition section. The speech recognition section analyzes and recognizes the voice signal and thereby obtains voice data. The voice data is compared with voice patterns that have been registered in the mobile communications terminal corresponding to individuals etc. and thereby a voice pattern that most matches the voice data is searched for and retrieved. If the retrieval of a matching voice pattern succeeded, a memory search processing section refers to a voice-data correspondence table and thereby calls up a telephone directory that has been registered corresponding to the retrieved voice pattern. In each telephone directory, various types of data (telephone number, mail address, URL, etc.) of an individual etc. to be used for starting communication have been registered previously. The type of data to be called up is designated by button operation etc. When a telephone directory is called up, data of the designated type is called up from the telephone directory and used for starting communication. By the employment of the telephone directories, the speech recognition rate can be maintained high even if the number of registered data increased, thereby operability of the mobile communications terminal can be improved.
