Embodiment Construction

[0036] In the following description of preferred embodiments of the present invention, the same or similar reference numerals are used for similarly functioning elements described in different figures, wherein repeated descriptions of these elements are omitted.

[0037] The above-mentioned prior art shows that various configurations are known for filtering information out of a database along a route or road section. This information is generally in a static database, either on the navigation device itself (digital map with additional information, eg POI information, travel guide), or in a central server accessed by means of wireless communication.

[0038] In the prior art, voice information is called up, for example, via a reference location. In the case of a very large number of voice messages, it is no longer possible to filter out the desired voice messages. An advantage of the invention is that, for example, the audible voice messages to be stored are processed by means...

Abstract

The invention relates to a method (200) for processing a voice signal (108) of a to-be-driven road section. The method (200) includes the step of extracting (210) the classified information (126) in the read voice signal (108), wherein the classified information (126) is suitable for the condition that the voice signal (108) is related to one of the multiple classifications, and the extraction (210) is realized when the voice recognition algorithm (122) is used. Besides, the method also includes the step of generating (220) the voice data group (134). The voice data group includes the voice signal (108) or the information (152, 152', 152'') led out from the voice signal on one side, and at least includes the classified information (126) one the other side to process the voice signal (108).

Description

technical field [0001] The invention relates to a method for processing speech signals relating to a route to be traveled, a corresponding device and a corresponding computer program product. Background technique [0002] The use of navigation systems in vehicles is now state of the art (with increasing rates of assembly). Here, one can distinguish between solid-state components (OEM navigation devices), so-called "portable navigation devices" (marketed by eg TomTom, Garmin) and smartphones with navigation software (eg Apple's iPhone). [0003] Methods are also known in which the navigation device requests information from a local database or from a central server with the aid of activated destination navigation and route information. [0004] DE 10 2009 031 275 A1 describes a method in which data is transmitted by means of a radio interface to a vehicle equipped with a navigation system. Since the radio interface to the vehicle is usually narrowband (eg GSM), the transmis...
