Method for processing voice signal of to-be-driven road section and device

Abstract

#CMT# # / CMT# The method involves extracting classification information (126) from a read speech signal (108) using a speech recognition algorithm (122), where the classification information is suitable to assign the speech signal to one of multiple classes. Language records (134, 134') are generated, where the language records comprise the speech signal or information i.e. text messages (152, 152', 152''), derived from the speech signal and the classification information to prepare the speech signal. The records are filtered and output in response to an output request signal (142). #CMT# : # / CMT# Independent claims are also included for the following: (1) a device for preparing a speech signal regarding a route to be traveled (2) a method for assisting a driver of a vehicle (3) a device for assisting a driver of a vehicle (4) a computer program product comprising program codes for preparing a speech signal regarding a route to be traveled and for assisting a driver of a vehicle. #CMT#USE : # / CMT# Method for preparing a speech signal regarding traffic and / or weather conditions of a route to be traveled by a vehicle i.e. motor car (from drawings). #CMT#ADVANTAGE : # / CMT# The method allows for grouping or classification of different speech signals in a simple manner using the speech recognition algorithm, thus enabling quick and efficient classification of the speech signals provided for the driver of the vehicle, while avoiding the need for separate classification of the speech signals by the driver of the vehicle, and hence enabling simple and quick selection of a certain speech signal from a high amount of speech signals available for a section of track of a travel route of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a schematic block diagram of a system for assistance of a driver of a vehicle. 108 : Read speech signal 122 : Speech recognition algorithm 126 : Classification information 134, 134' : Language records 142 : Output request signal 152, 152', 152'' : Text messages.

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...
