Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for outputting speech language information (voice) of a digitally coded traffic message received by using a broadcast receiver,
The traffic message includes a code for displaying a place and a position in the geographical area, where a place (position) name corresponding to each code is retrieved from the table for outputting speech language information, and the table is displayed. Relates to a device for outputting the speech language information (sound) stored in the memory belonging to the broadcast receiver.

2. Description of the Related Art A radio data system (RDS) enables additional inaudible transmission of digital data in parallel to a broadcast program (program) on a data channel. The specifications of the radio data system (RDS) for ultra-short wave (UKW) broadcasting are stipulated in the publication of the EBU (European Broadcasting Union) Tech.3244-E, March 1984. A broadcast receiver with a suitable RDS-decoder can additionally receive and decode transmitted data in addition to receiving the broadcast by the same receiver. The data transmission is carried out in 32 groups of 108 bits each. Here, one fixed service is assigned to each group. Each group 8a is provided for the transmission of digitally coded traffic messages. The structure and coding of the traffic message concerned are proposed by the standard (standard) ALERT C N
overmber 1990, RDS ATT ALE
RTConsortium, published). Here, the most important elements of a certain traffic message are a location and an event. The information is cataloged, that is,
One unique code is assigned to each event related to location (location) and communication (message). A cascading arrangement (chain) of the places (positions) in the place (position) table along the existing road represents the state of progress (progress). Traffic Message Channel (Traffic Message Channel)
To use the TMC, in addition to a receiving device having an RDS decoder, a device for decoding, storing, subsequent processing, and outputting a traffic message is required.

Broadcasting reception of a traffic message regardless of the place (position) where the traffic message is involved and by transmitting the traffic message by decoding the traffic message and converting it into speech language information first performed by the receiver. Unrelated to the machine,
It becomes possible to output the speech language information with the speech language information understood by each user. For this, only the means for generating the speech language information to be output is necessary. In general, a motor vehicle operator can equip a car radio with a speech output device, which can output traffic messages in the relevant speech language information. For this purpose, in particular words and sentences are stored in the receiver which describe the event and its extent (magnitude). For example, "traffic jam" and "length of 3 km" are stored.

A further element of the speech language information is the location (location) name, to which the code is transmitted in a traffic message. For the purpose of the audio output, the table (which is stored in the memory belonging to the broadcast receiver) stores the location (position) belonging to the code. Advantageously, such a memory is arranged on a replaceable data carrier, eg a chip card. The advantage that is gained thereby is that the table does not need to contain, to a large extent, all codes and location names of all geographical areas used by the broadcast receiver. In addition, constant changes in the location (location) in question should be anticipated and taken into account. This is because, over time, the road network and its associated locations (locations) -autobahn terminal (junction) points-are changed or new roads are constructed. Therefore, when arranging the memory on the exchangeable data carrier, the user can obtain the data carrier for the area in which he / she travels when there is a change,
Then, in an area where the vehicle rarely travels, it becomes possible to prepare an actual data carrier immediately before the start of travel.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to enable the output of speech language information of a decoded traffic message as follows, that is, another speech language (information) is used. For the geographic area spoken (used) or even if one data carrier is used, the place names are also to a considerable extent output in the speech language information to be output as usual. It is to enable the output of speech language information.

[0006]

The above problem is solved according to the features of the claims as follows, that is, the speech of a digitally encoded traffic message received using a broadcast receiver. A device for outputting linguistic information, wherein the traffic message (notification) includes a code for displaying a place and a position in a geographical area, wherein a place corresponding to each code for outputting speech linguistic information. In the speech language information output device in which the (position) name is retrieved from the table, and the table is stored in the memory belonging to the broadcast receiver, the location (position) name in the table is the first speech language. Information and, if present, at least one additional speech language information, and In order to output the speech language information of one place (position) name, it is checked whether or not the place (position) name is stored in the table, and if there is, the place (position) name. Is read by the speech language information, and when it is not present, it is read by the first speech language information.

The advantage obtained by the apparatus of the present invention is that the place (position) name known from different foreign language or foreign foreign language speech information for each geographical area also corresponds to the speech language information. It is output by. Thus, for example, in French as speech language information to be output using the device according to the invention, the location (position) "Aix 1a c
“Hapelle” is used instead of “Aachen”.

An advantage of the device according to the invention is that the memory locations for the tables are only slightly greater than for single speech language information tables. This is because most place (position) names appear in the speech language information corresponding to each area.

As a result, the information necessary for using the table is called when the chip card is inserted, the receiver is inserted in the mounted state, or when the chip card is inserted. Moreover, access to individual data sets, each belonging to one code, is significantly facilitated.

In this development, the memory locations for the identification of the individual places in the further speech language information are saved in the following way: the table is for each one code in the first language. A location holder containing the location name in the information and the existing location name in the further speech language information, and in place of the nonexistent location name in the further memory (Support information) is stored. According to another embodiment of the present invention for quickly finding and reading a place (position) with further speech language information, the place (position) names are each the place (position) in the first speech language information. It is stored in a predetermined order together with the name, and the predetermined order corresponds to the order in the table display contents.

If necessary, the apparatus of the present invention can be configured as follows: the speech language information to be output is fixedly set by the speech language information generating apparatus in the broadcast receiver. The speech language to be output is selectable at the broadcast receiver. Depending on the latter configuration, the broadcast receiver will be more expensive, but there are advantages because it ensures availability for multiple speech language information when making the broadcast receiver. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to a plurality of drawings.

In the drawings, the same components are designated by the same reference numerals. Although the embodiments and their parts are shown as block schematics, this does not mean that the circuit arrangement of the invention is not limited to the individual circuits corresponding to each block. On the contrary, the circuit arrangement according to the invention can be implemented particularly advantageously by means of highly integrated circuits. A digital signal processor can be used here, under which the processing steps shown in the block diagram can be carried out under suitable programming. Example 1 with additional circuit arrangement
It can form an important part of one broadcast receiver in one IC circuit.

The header shown in FIG. 1 has an RDS-country (state) -code RDS-CC, which code indicates which country (state) the table is for. The code above is for example E
It is OD. At the second location (position), there is a speech language information identifier stored as an inner code (symbol), in other words, an identifier of speech language information of the area where the location (position) is located. In this example, de = Germany. Furthermore, in the header, the outer code (outer symbol), that is,
The number of additional speech language information is shown, in the example above two speech language information are indicated. Following that is the first inner code (inner symbol), for example en =
An identifier of English and a second outer code (outer symbol) fr = French.

An identifier is provided in the left column of the table (the header shown in FIG. 1 is applicable to the table) shown in FIG. 2, and an inner code (symbol) is provided in the second column.
Outer codes (symbols) are provided in English and French in the third and fourth columns. Missing outer code (symbol) (because foreign language location designations are not customary in each case) a location holder (which contains one or more symbols that differ from all other symbols) Is entered. The order of outer codes (symbols) in the table is the same as the corresponding speech language information in the header. As a result, no individual inner code (symbol) identifier is required.

It is advantageous to use notations in the table that facilitate the production of speech linguistic information, for example generated symbols.
In the description of the embodiments, a usual form is selected for optical output for the sake of clarity.

Of the broadcast receiver, FIGS. 3 and 4 show only the functions necessary for explaining the speech language information output of the present invention. The traffic message processing device 21 is supplied at 22 with a signal of group 8a from an RDS decoder (not shown). According to the ALERT specification described above, the data in question essentially contains information about the location (position), type, expected duration, magnitude and direction of the event. The information is provided by the device 21 (which is preferably implemented in the form of a microcomputer or digital signal processor).
In, it is decoded and sorted. The screening is done according to the screening discriminant measure supplied via the input unit 23, so that, for example, the traffic message relating to the entered path segment in one input direction is reproduced.

Data already stored in the location (location) list 25 is needed for decoding the traffic message, eg the location (location) (closest) to the location (location) indicated in the traffic message. Data is required on the road progress and belonging to one area. The relevant and further information is stored in a location list on the chip card and can be read using a reading device present in the receiver like other information described below. According to the example shown in the figure, the place (position) NO, 4711 belongs to the area 2009, and the adjacent place (position) NOs 4710 and 471.
It is 712. Further place (location) list 25
It contains the location (position) from the table and an identifier used for reading other designations. Thus, for example, the identifier 15 can mean the word Koeln and the identifier 81 can mean the word Nord. The use of the identifier, which has a certain number of digits, saves a great deal of memory location.

The traffic message thus decoded is supplied to a device 26 for speech language information, the output signal of which is supplied to a speaker 16 via a D / A converter 14 and an audio amplifier 15. . The device 26 may advantageously also be realized by means of a digital signal processor, so that the signal processor is supplied with the program 27. The data necessary for speech language information synthesis are supplied to the event set list 2, carrier set list 3 and segment library 4 from a table (which is stored on the chip card 24).
The synthesis is performed with the following speech language information, that is, the speech language information with which the event set list 2, the carrier set list 3, and the segment library 4 are created. A process (technique) specially adapted for the output of coded traffic messages is disclosed in the patent application “Verfahren z
urAusgabe von digital cod
ierten Verkehrsmeldungen
mittels synthesisch erzeu
gter Sprache ".

In addition to variable location designations, there are, for example, numbers associated with the terminal points 15 in the table 1. Of course, it is important to listen to the number of the terminal point with predetermined speech language information (the other part of the output is performed by the speech language information).
In Table 1, the number 15 is stored as the number. In the case of speech language information output, it relies on a special part of the segment library 4, in which the pronunciation of numbers is stored in the respective speech language information of the receiver. Further, in Table 1, the position (position) 1 is written in a usual notation, so that the chip card 24 can be used to output the optical speech language information.

In Table 1, in addition to designation of location (position), speech language information (internal code (symbol) of each area and location (position) designation (outer code (symbol)) composed of other speech language information) Stored (as long as such is customary) stored in Koeln, or cologne in French, the receiver of FIG.
The location (position) present in the speech language information of the receiver may be selected. In the case shown, for example, speech language information, English, Dutch, German, or French can be selected. If the location (position) designation is not stored under the speech language information of the receiver (this occurs at a plurality of locations (positions) in the figure), the location (position) designation existing in the table 1 is speech. Used for outputting language information.

The point of the further means for improving the quality of speech language information is that the position (position) designation supplied by the speech language information different from the speech language information of the receiver is supplied to the prosody conversion unit 29. To be done. The seed converter is known per se and changes the speech language information melody towards the speech language (information) of the receiver.

A configuration arrangement for speech language information synthesis is performed by a special operation after turning on the receiver or when the chip card is replaced. The German receiver has a chip card with a location list, including for example Table 1 for France. After injection, the receiver identifies in the header (Fig. 1) that this is the case for a location list for France, which also has a German location. Therefore, the receiver selects conversion of French prosody into German prosody by the prosody converter. In addition, each time the location (location) name list or table is accessed, the following is checked: whether a German designation exists for a location (location). Checked. If there is no German designation, the "source prosody" (here French) is transferred to the "target prosody" (here German).

In the case of the receiver of FIG. 4, the event set list and the carrier set list exist with multiple speech language information, ie German, English and French respectively, the event set list 2de, 2en, 2fr and the carrier set list. It exists as 3de, 3en, 3fr. Furthermore, the segment library 4'is extended with a special segment of added speech language information, all speech language information spoken here being from the same speaker. Thereby, the traffic message can be output with a plurality of speech language information. By the selection device 28 and the prosody conversion unit 29, the place (position) included in the place (position) list can be adapted to the speech language information selected each time.

[0025]

According to the invention, it is to enable speech language information of a decoder traffic message as follows: a data carrier for a geographical area in which other speech language information is used is used. Even in such a case, it is possible to obtain the effect of enabling the output of the relevant speech language information so that the speech language information should be output sufficiently as usual.

The effect is obtained.
