<p>In an interactive process using speech recognition together with a graphical user interface (801) comprising a plurality of settable graphical user interface items (802), the recognition rate is improved by reducing recognition target vocabulary. A settable graphical user interface item not displayed on the display screen (901) is detected (S201), and the received speech information is recognized (S208) using a speech recognition grammar (601) corresponding to the detected item, and data is set to the item using the recognition result.
