Definitions

  • the invention relates to a device according to the preamble of the main claim.
  • the radio data system enables an additional and inaudible transmission of digital data in parallel to radio programs in a data channel.
  • Specifications of the radio data system for VHF radio can be found in Tech. 3244 - E, March 1984 of the European Runfunk Union (EBU).
  • Radio receivers with suitable RDS decoders can record and decode transmitted data in addition to radio reception with the same receiver.
  • the data transmission takes place in 32 groups of 108 bits each, each group being assigned a specific service. Group 8a is intended for the transmission of digitally coded traffic reports.
  • the structure and coding of these traffic reports are specified in the standard proposal ALERT C, November 1990, published by the RDS ATT ALERT Consortium.
  • the essential elements of a traffic announcement are the location and the event. This information is cataloged, which means that a unique code is assigned to every traffic-relevant location and every traffic-relevant event.
  • the chaining of the locations in the location table along existing streets shows the course.
  • facilities for decoding, storing, further processing and outputting the traffic reports are required to use the traffic message channel TMC (Traffic Message Channel).
  • TMC Traffic Message Channel
  • place names for which codes are transmitted in the traffic reports are place names for which codes are transmitted in the traffic reports.
  • the place names belonging to the codes are stored in a table which is stored in a memory assigned to the radio receiver.
  • a memory is preferably arranged on an exchangeable data carrier, for example a chip card.
  • the table does not have to include all codes and place names of all geographic areas in which the radio receiver may be operated.
  • this list of places is constantly changing, as the road network and the associated places - such as motorway junctions - change or new roads are built over time.
  • a user When arranging the memory on an exchangeable data carrier, a user therefore has the option of acquiring a data carrier for the area he is traveling on in the event of changes, and of obtaining an up-to-date data carrier in areas that he uses less frequently before starting a journey.
  • the object of the present invention is to enable the voice output of the digitally coded traffic reports in such a way that the place names are output as far as usual in the language to be output, even if a data carrier is used for a geographical area in which another language is spoken.
  • place names are stored in the table in a first language and, if available, in at least one other language, that for the speech output a place name is checked whether the place name is stored in the table in the language to be output and that if there is a place name in this language and if there is no place name in the first language.
  • the device according to the invention has the advantage that those place names that are known in a language that is foreign to the respective geographical area are output in this language. For example, with the help of the device according to the invention with French as the language to be output, a driver in Germany the place name "Aix la Chapelle" was announced instead of "Aachen”.
  • the device according to the invention also has the advantage that the required storage space for the table is only slightly larger compared to a monolingual table, since most place names are only available in the language valid for the respective area.
  • a further development of the device according to the invention is that a description of the table is also stored in the memory, which contains the geographical area to which the table applies, the first language, the number of further languages and the further languages.
  • the information required to use the table can be queried as soon as the receiver is switched on with the inserted chip card or when the chip card is inserted.
  • access to the individual data records belonging to a code is made considerably easier.
  • the language to be output is predefined by a speech generation device in the radio receiver or that the language to be output is selectable in the radio receiver.
  • the latter increases the cost of the radio receiver, it can bring advantages for logistical reasons, since the usability for users of multiple languages is retained when producing a radio receiver.
  • the header shown in FIG. 1 contains an RDS country code RDS-CC, which indicates the country for which the table is designed. This is, for example, E0 D.
  • RDS-CC indicates the country for which the table is designed. This is, for example, E0 D.
  • identifiers are given in the left column, the endonyms in the second column and exonyms in the languages English and French in the third and fourth columns listed. If there are no exonyms, because foreign language place names are not common in the respective case, a placeholder is entered that contains one or more characters that differ from all other characters. The order of the exonyms in the table is identical to the order of the corresponding languages in the header. It is therefore not necessary to identify individual exonyms.
  • the signals of group 8a are fed to a traffic message processing device 21 at 22 from an RDS decoder (not shown).
  • this data essentially contains information about the location, type, expected duration, size and direction of an event.
  • This information is decoded and selected in the device 21, which is preferably implemented in the form of a microcomputer or a digital signal processor. A selection takes place in accordance with the selection criteria supplied via an input unit 23, so that, for example, only those traffic reports are reproduced which relate to the entered road section in a given direction.
  • Data stored in a place list 25 is already required for decoding the traffic reports, for example the places closest to the place mentioned in the traffic report in the course of a street and the affiliation to an area.
  • This and other information are stored in a location list on a chip card 24 and, like other information described later, can be read with the aid of a reading device in the receiver.
  • the location no. 4711 belongs to an area in 2009 and that the neighboring locations are 4710 and 4712.
  • the location list also contains 25 identifiers which are used to read the location names and other names from Table 1.
  • the identifier 15 can mean the word Cologne and the identifier 81 the word north.
  • the traffic messages decoded in this way are fed to a device 26 for speech synthesis, the output signals of which are fed to the loudspeaker 16 via the digital / analog converter 14 and the audio amplifier 15.
  • the device 26 can also advantageously be implemented with the aid of a digital signal processor, to which a program 27 is available.
  • the data required for speech synthesis are fed from table 1, which is stored on chip card 24, to an event record list 2, a carrier record list 3 and a segment library 4.
  • the synthesis then takes place in the language in which the event record list 2, the carrier record list 3 and the segment library 4 are created.
  • Speech synthesis methods are known per se. A method which is particularly tailored to the output of coded traffic reports is described in the patent application filed simultaneously by the applicant "Process for outputting digitally coded traffic reports by means of synthetically generated speech".
  • table 1 also contains numbers, such as in connection with the connection point 15. Since it is naturally important to hear the number of a connection point in the language in which the rest of the output takes place, in the Table 1 stores the number 15 as a number. A special part of the segment library 4 is used for the speech synthesis, in which the pronunciation of the numbers is stored in the respective language of the recipient. Furthermore, the place names are in the usual font in Table 1, so that an optical voice output can also take place with the aid of the chip card 24.
  • table 1 In addition to the place names in the language of the respective area (endonyms), table 1 also contains place names from other languages (exonyms), if such are used.
  • exonyms For example in the French language Cologne.
  • the receiver according to FIG. 3 can use a selection device 28 to select the place name available in the language of the receiver. In the case shown, for example from the languages English, Dutch, German and French. If no place name is stored under the language of the recipient, which will be the case with the majority of places in a country, the place name available in Table 1 is used for speech synthesis.
  • a further measure for improving the speech quality consists in the fact that the place names supplied in a language other than the language of the recipient are fed to a prosody conversion 29. Such a conversion is known per se and changes the speech melody in the direction of the language of the recipient.
  • a German-speaking recipient for example, contains a chip card with a list of locations including Table 1 for France. After switching on, the receiver recognizes by the header (Fig. 1) that it is a chip card with a location list for France, which also contains German-speaking place names. The recipient then selects the conversion of the French prosody into German prosody on the prosody converter. Each time the location list or table is accessed, a general check is carried out to determine whether a location has a German-language name or not. If there is no German-language name, the "source prosody" (here French) is converted into the "target prosody” (here German).
  • the event set list and the carrier set list are available in several languages, namely in German, English and French as event set lists 2de, 2en, 2fr and carrier set lists 3de, 3en and 3fr.
  • the segment library 4 is expanded to include special segments of the added languages, all languages being spoken by the same speaker. This means that the traffic reports can be issued in several languages.
  • the selection device 28 and the prosody conversion 29 the place names contained in the place list can be adapted to the respectively selected language.
