Speech processing apparatus and control method thereof

A method for a speech processing apparatus adapted to display a plurality of screens of a hierarchical menu and set shortcut data that provides a shortcut to each respective screen, the method comprising:

• selecting screen from among the plurality of screens;
• determining whether the selected screen corresponds to a level which is deeper than a predetermined depth from a root level of the hierarchical menu;
• registering, in a case where it is determined that the selected screen corresponds to the level which is deeper than the predetermined depth, a speech recognition target vocabulary corresponding to the selected screen to a speech recognition grammar, and associating and storing the registered speech recognition target vocabulary and a shortcut data for transitioning to the selected screen;
• inputting a speech;
• recognizing the input speech using the speech recognition grammar;
• and
• displaying, using a control unit and by using the shortcut data corresponding to the recognized speech recognition target vocabulary, the screen corresponding to the recognized speech recognition target vocabulary,
• wherein, in a case where it is determined that the selected screen does not correspond to the level which is deeper than the predetermined depth, registering does not include registering the speech recognition target vocabulary corresponding to the selected screen, and does not include associating and storing the registered speech recognition target vocabulary and the shortcut data for transitioning to the selected screen.

A non-transitory computer-readable storage medium storing a program that causes a speech processing apparatus adapted to perform a method to display a plurality of screens of a hierarchical menu and set shortcut data that provides a shortcut to each respective screen, the method comprising:

• selecting a screen from among the plurality of screens;
• determining whether the selected screen corresponds to a level which is deeper than a predetermined depth from a root level of the hierarchical menu;
• registering, in a case where it is determined that the selected screen corresponds to the level which is deeper than the predetermined depth, a speech recognition target vocabulary corresponding to the selected screen to a speech recognition grammar, and associating and storing the registered speech recognition target vocabulary and a shortcut data for transitioning to the selected screen;
• inputting a speech;
• recognizing the input speech using the speech recognition grammar;
• and
• displaying, using a control unit and by using the shortcut data corresponding to the recognized speech recognition target vocabulary, the screen corresponding to the recognized speech recognition target vocabulary,
• wherein, in a case where it is determined that the selected screen does not correspond to the level which is deeper than the predetermined depth, registering does not include registering the speech recognition target vocabulary corresponding to the selected screen, and does not include associating and storing the registered speech recognition target vocabulary and the shortcut data for transitioning to the selected screen.
