Abstract

The invention relates to a method for selecting a list item from a selection list, especially in an automotive information or entertainment system, whereby optionally a search list item is input in a speech mode by speech input or in a manual input mode by manual input. According to the invention, in the speech input mode, the search list item is input as a spoken word and the spoken search list item is compared with the list items of the selection list. If there is sufficient agreement between the spoken search list item and at least one of the list items from the selection list, said at least one list item is selected as the search result. If there is not sufficient agreement between the spoken search list item and at least one of the list items of the selection list, the system automatically switches over to the manual input mode.

Claims

1-15. -15. (canceled)

16. A method for selecting a list item from a selection list comprising a plurality of list items in a system having a voice input device for receiving a voice input in a voice input mode and a manual input device for receiving a manual input in a manual input mode, said method comprising the steps of:

inputting a desired list item to the system as a voice input in the voice input mode;

comparing the voice input with the plurality of list items in the selection list;

selecting one list item from the selection list if the one list item has at least a minimum correspondence with the spoken word;

automatically changing over to the manual input mode if none of the plurality of list items in the selection list have at least the minimum correspondence with the spoken word and storing the voice input before said step of automatically changing;

manually inputting an input character string in the manual input mode after said step of automatically changing;

determining matching ones of the plurality of list items in the selection list having an initial part corresponding to the input character string and comparing the stored voice input to the matching ones of the plurality of list items if the amount of matching ones of the plurality of list items is less than a predetermined amount;

selecting one list item from the matching ones of the plurality of list items in the selection list if the one list item has at least a predetermined correspondence with the voice input; and

outputting an indication of the selected one list item from the selection list or the selected one list item from the matching one of the plurality of list items optically or acoustically.

17. The method of claim 16, wherein said step of inputting an input character string comprises inputting the input character string character by character using a handwriting input apparatus or a keypad in the manual input mode.

18. The method of claim 17, wherein said step of inputting character by character further comprises the step of providing an optical or acoustic feedback after each character has been input.

19. The method of claim 16, wherein said step of determining matching ones comprises automatically comparing the character string that has been manually input to the plurality of list items in the selection list, determining the number M of list items containing the input character string as an initial part, determining whether the number M is less than a prescribed value X and greater than 1, and at least one of offering the list items containing the input character string as an initial part for selection on an optical display apparatus or changing over to the voice input mode if it is determined that the number M is less than a prescribed value X and greater than 1.

20. An information or entertainment system, comprising:

a memory module storing a plurality of list items;

a manual input apparatus for receiving a manual input indicating a desired list item;

a voice input apparatus and a voice processing apparatus for receiving a voice input indicating the desired list item, said voice processing apparatus processing spoken words;

a selection module selecting one of the plurality of list items based on the voice input or the manual input and having a changeover module arranged and dimensioned for manually and automatically changing between the manual input mode and the voice input mode, said selection module further comprising

means for storing the voice input before automatically changing over to the manual input mode,

means for comparing the stored voice input with those list items in the selection list whose initial part corresponds to the character string which has been manually input if the number of list items determined in this manner is less than a prescribed value, and

means for selecting a list item from those list items in the selection list whose initial part corresponds to the character string which has been manually input if the correspondence of the list item to the stored voice input is greater than a minimum correspondence; and

an output device providing one of an optical or acoustic indication of the selection.

21. The information or entertainment system of claim 20, wherein said manual input apparatus is a handwriting recognition apparatus.

22. The information or entertainment system of claim 20, wherein said manual input apparatus has a touch-sensitive surface.

23. The information or entertainment system of claim 22, further comprising a rotary controller, wherein said touch-sensitive surface is integrated in said rotary controller.

24. The information or entertainment system of claim 22, further comprising a display apparatus, wherein said touch-sensitive surface comprises a touchscreen integrated in said display apparatus.

25. The information or entertainment system of claim 20, wherein said information or entertainment system comprises a navigation system and each of said plurality of list items indicates a location.

26. The information or entertainment system of claim 20, wherein said information or entertainment system comprises at least one of an audio and video system and each of said plurality of list items indicates one of a transmitter frequency, a transmitter name, a telephone number, or a music or video title.

27. The information or entertainment system of claim 20, wherein said information or entertainment system comprises an information system for public transport or for tourists.

28. The information or entertainment system of claim 20, wherein said information or entertainment system comprises a bank information system.
