The Insert the card-shaped device attached to stuttering group, and a calibration device using the same are disclosed. In one embodiment, disposed in the terminal-mounted card inserted into the case group and the case where the insertion of memory card is built-in and a gender for connecting the card to be inserted into the casing with the terminal and electrically. The memory of the card may be connected to the electrical terminal and through the gender. In the memory of the card, see the app running on the terminal or necessary data to the app drive - hereinafter referred to as app drive data - stored at least a portion of the separated from the terminal, of the app driving data from outside hacking wherein at least a portion can be securely protected. In another embodiment, the stuttering correction apparatus using the terminal group attached card is inserted into card insertion include groups attached to the terminal and the terminal. The terminal the user to play the sound by receiving by receiving a user of the audio output signal of the signal processing unit and said signal processing section for outputting by delaying the electrical signal received, and receiving the microphone, the electric signal to convert into an electrical signal It includes a sound reproduction to provide. Disposed in the card insertion and the case group and the case where the insertion of memory card is built-in and a gender for connecting the card to be inserted into the casing with the terminal and electrically. The delayed output of the electrical signal received through the microphone by the signal processing can be performed according to a preset command to the command input of the user or the app via an app running on the terminal. In the memory of the card, the app reference or necessary data to the app drive - hereinafter referred to as app drive data - at least a portion of the stored separate from the terminal, the app is the only state in which the terminal and the card
