Abstract

A voice dialing system for calling up addresses filed in an address store by means of a microphone and a voice recognition unit which is combined with a device for reproducing and/or processing the addresses called up and which forms the request signal from the spoken audio signals by means of signal comparison for selecting the relevant address. The voice recognition unit is set up for recognition of each word provided for the discrete alphabetic letters and for the conversion of such a spoken word into corresponding alphabetic letter signal and generates the selection signal from alphabetic letter signals formed from voice input of a sequence of words of the letter alphabet .

Description

Die Erfindung bezieht sich auf ein Sprachanwahlsystem zum Abrufen von in einem Adressenspeicher abgelegten Adressen der im Gattungsbegriff des Patentanspruchs näher bezeichneten Art. The invention relates to a voice dialing system for Retrieve addresses stored in an address memory the closer in the preamble of claim designated Art.

Solche Sprachanwahlsysteme finden heute vor allem im Mobilfunksektor eine zunehmende Verbreitung. Die auch als "Voice Dial"-Wählfunktion bezeichnete Sprachanwahl erspart ein mehrfaches, umständliches Manipulieren am Telefongerät, so daß trotz eines eingeleiteten Wählvorganges die Bedienungsperson sich auf andere Dinge konzentrieren kann. Dies ist vor allem beim Fahren von Kraftfahrzeugen von erheblicher Bedeutung, um nicht von der Verkehrsbeobachtung abgelenkt zu werden. Such voice dialing systems are mainly found today in Mobile sector an increasing spread. The also called "Voice Dial "dialing function designated voice dialing saves one multiple, cumbersome manipulation on the telephone device, so that despite an initiated dialing process Operator can concentrate on other things. This is especially significant when driving motor vehicles Importance, so as not to be distracted from traffic observation to become.

Allerdings stößt das bekannte Sprachanwahlsystem dort an seine Grenzen, wo es um eine Steigerung der Anzahl der aus dem Adressenspeicher abrufbaren Adressen geht. Zum einen ist es bei einer Vielzahl von Adressen meist unvermeidbar, daß für die einzelnen Speicherplätze des Adressenspeichers Codeworte eingesprochen und in der Wiedererkennungseinheit eingespeichert werden müssen, die einander phonetisch ähnlich sind. Dann kann es auch bei hoher Empfindlichkeit der Elektronik für den Signalvergleich in der Spracherkennungseinheit zu Verwechslungen kommen, wodurch für das in das Mikrofon eingesprochene Codewort im Adressenspeicher nicht der passende Speicherplatz gefunden wird. Zum anderen setzt die Speicherkapazität für den Signalvergleich in der Speichererkennungseinheit Grenzen, wodurch für viele denkbare Einsatzfälle das Sprachanwahlsystem noch nicht zur Anwendung kommen kann. However, the well-known voice dialing system triggers there its limits where there is an increase in the number of the address memory accessible addresses goes. On the one hand it is usually inevitable with a large number of addresses, that for the individual memory locations of the address memory Codewords spoken in and in the recognition unit must be stored that are phonetic to each other are similar. Then it can also with high sensitivity of the Electronics for signal comparison in the Speech recognition unit can be confused, which for that in the Microphone spoken code word in the address memory is not the appropriate storage space is found. On the other hand, sets the storage capacity for the signal comparison in the Memory recognition unit limits, making it conceivable for many The voice dialing system is not yet in use Application can come.

Derartige Anwendungsfälle sind zum Beispiel Telefonregister mit einer Vielzahl von Namen, von denen jeder als Codewort in den Speicher der Wiedererkennungseinheit eingegeben werden müßte. Gleiches trifft für Navigationssysteme von Fahrzeugen zu, für die eine Vielzahl von Ortsnamen als anwählbare Adressen zu berücksichtigen sind, wofür bislang nur eine manuelle Adressenanwahl in Betracht kommt. Aus Sicherheitsgründen ist es jedoch erstrebenswert, bei einem Navigationssystem in einem Kraftfahrzeug den Namen des Zielortes im Voice-Dial-Verfahren anwählen zu können. Such use cases are, for example, telephone registers with a variety of names, each as a code word entered into the memory of the recognition unit should be. The same applies to navigation systems from Vehicles for which a variety of place names as selectable addresses have to be taken into account, for which only so far a manual address selection is possible. Out For security reasons, however, it is desirable for one Navigation system in a motor vehicle the name of the To be able to select the destination using the voice dial method.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Sprachanwahlsystem der gattungsgemäßen Art zu schaffen, bei dem die Anzahl der aus dem Adressenspeicher abrufbaren Adressen beliebig erhöht werden kann. The invention is therefore based on the object To create voice dialing system of the generic type at the number of those that can be called up from the address memory Addresses can be increased as required.

Diese Aufgabe wird nach der Erfindung bei einem Sprachanwahlsystem der gattungsbildenden Art durch die kennzeichnenden Merkmale des Patentanspruchs gelöst. This object is achieved according to the invention Voice dialing system of the generic type by characterizing features of the claim solved.

Für die Erfindung ist wesentlich, für den Sprachvergleich in der Spracherkennungseinheit lediglich diejenige Anzahl von Wörtern berücksichtigen zu müssen, die das jeweilige Buchstabieralphabet umfaßt. Ein solches Buchstabieralphabet wird auch als Buchstabiertafel bezeichnet, mit der für unterschiedliche Bereiche verschiedene Begriffe für die einzelnen Buchstaben verwendet werden. So gibt es eine Fernsprech-Buchstabiertafel Inland für die Bundesrepublik Deutschland, eine Fernsprech-Buchstabiertafel Ausland und eine internationale Sprechfunk-Buchstabiertafel. Letztere sieht für die Buchstaben von A bis Z sechsundzwanzig charakteristische, leicht auseinanderzuhaltende Wörter vor, die sich auch im Vergleicher der Spracherkennungseinheit des neuen Sprachanwahlsystems leicht auseinanderhalten lassen. It is essential for the invention, for the language comparison only that number in the speech recognition unit of having to take into account words that each Spelling alphabet included. Such a spelling alphabet is also known as the spelling board with which for different areas different terms for the individual letters can be used. So there is one Telephone spelling board in Germany for the Federal Republic Germany, a telephone spelling board abroad and an international radiotelephony spelling board. Latter looks for the letters from A to Z twenty six characteristic, easily distinguishable words, which is also in the comparator of the speech recognition unit easily distinguish the new voice dialing system to let.

Damit ist der Signalvergleich in der Spracherkennungseinheit auf solche sechsundzwanzig Begriffe beschränkt, was sich leicht vom baulichen Aufwand her realisieren läßt. Zwar muß ein Zwischenspeicher vorgesehen werden, in dem das Wählsignal für den Adressenspeicher zusammengestellt wird, das aber wird bei weitem durch die Sicherheit der Signalübertragung und die mögliche Erhöhung der Kapazität des Adressenspeichers aufgewogen. Dies gilt auch bezüglich der zusätzlich zu berücksichtigenden Kommandos, die für Start und Stop für das Einsprechen des der jeweiligen anzuwählenden Adresse entsprechenden Codewortes erforderlich sind. So the signal comparison in the Speech recognition unit limited to such twenty-six terms what can be easily implemented in terms of construction. A buffer must be provided in which the Dial signal for the address memory is compiled, but that is by far the security of the Signal transmission and the possible increase in capacity of the Address memory weighed. This also applies to the additional commands to be considered for start and stop for speaking of each corresponding code word to be selected are required.

Die internationale Sprechfunk-Buchstabiertafel sieht für die einzelnen Buchstaben folgende Wörter vor:
A = Alfa
B = Bravo
C = Charlie
D = Delta
E = Echo
F = Foxtrott
G = Golf
H = Hotel
I = India
J = Juliett
K = Kilo
L = Lima
M = Mike
N = November
O = Oscar
P = Papa
Q = Quebec
R = Romeo
S = Sierra
T = Tango
V = Viktor
W = Whiskey
X = X-ray
Y = Yankee
Z = Zulu The international radio spelling board provides the following words for the individual letters:
A = Alfa
B = Bravo
C = Charlie
D = delta
E = echo
F = Foxtrot
G = golf
H = hotel
I = India
J = Juliett
K = Kilo
L = Lima
M = Mike
N = November
O = Oscar
P = dad
Q = Quebec
R = Romeo
S = Sierra
T = tango
V = Viktor
W = whiskey
X = X-ray
Y = Yankee
Z = Zulu

Die Eingabe des Ortsnamens "Berlin", wie sie beispielsweise für das Navigationssystem in einem Personenkraftwagen vorgenommen werden muß, umfaßt damit die Wortfolge: Bravo- Echo-Romeo-Lima-India-November. In analoger Weise können auch andere Buchstabieralphabete oder -tafeln zur Anwendung kommen. Entering the place name "Berlin", for example for the navigation system in a passenger car must therefore be carried out includes the following: Bravo Echo-Romeo-Lima-India-November. In an analogous way you can other spelling alphabets or tablets are also used come.
