Speech recognition apparatus, navigation apparatus including a speech recognition apparatus, and a control screen aided speech recognition method

A method for speech recognition comprising:

• displaying an operation control screen on a display, the operational control screen being configured to control one or more operably connected electronic devices through a plurality of voice inputs;
• calculating the matching degree for a plurality of speech recognition candidates by comparing a plurality of comparison data used to recognize voice inputs with voice input data generated based on a voice input of the plurality of voice inputs;
• adding addition data to the calculated matching degree for one or more particular comparison data within the plurality of comparison data that are associated with addition data to weight the matching degree;
• and
• recognizing the voice input based on the weighted matching degrees obtained as a result of the addition of the addition data,
• wherein, when an operation control screen already configured to a particular electronic device is displayed prior to the voice input, comparison data other than the particular comparison data corresponding to the addition data associated with the operation control screen for the electronic device are removed from the comparison data selected by the speech recognition unit as recognition candidates.

A speech recognition apparatus comprising:

• a control unit having a controller operably connected to one or more electronic devices, the controller being configured to display an operation control screen on a display for controlling the respective electronic devices, wherein, when the speech recognition apparatus is in a voice input configurational condition, the respective electronic devices are controlled by the controller through voice input;
• a speech recognition dictionary including comparison data for use in recognition of a voice input;
• a speech recognition unit adapted to calculate a matching degree by comparing voice input data generated based on the voice input with the comparison data, recognize the voice input based on the matching degree, and produce the recognition result of the voice input;
• and one or more addition data which are associated with one or more particular comparison data, wherein the one or more addition data is added to the matching degree of the particular comparison data thereby weighting the matching degree, and wherein the speech recognition unit produces the recognition result of the voice input based on the weighted matching degree for the particular comparison data,
• wherein, when the matching degree of first comparison data calculated for a voice input and the matching degree of second comparison data calculated for the same voice input both satisfy a predetermined matching condition, if the first comparison data is associated with the operational control screen already configured to a particular electronic device before the voice input is accepted, the addition data associated with the first comparison data is assigned a greater weight than the addition data associated with the second comparison data.
