Method for generating a context-based voice dialogue output in a voice dialog system

1 . A method for generating a context-based voice dialog output in a voice dialog system having transactions, each transaction having transaction parameters, each transaction parameter having a plurality of possible parameter values, comprising:

allocating a first parameter value to a transaction parameter of a first transaction;

thematically matching the first parameter value with a matching possible parameter value of a second transaction parameter of a second transaction;

determining a second parameter value for a third transaction parameter of the second transaction; and

generating a voice dialog output which comprises at least the first parameter value and the second parameter value.

2 . The method as claimed in claim 1 , wherein

the voice dialog system comprises a plurality of voice dialog applications, and

the first transaction is part of a first voice dialog application and the second transaction is part of a second voice dialog application.

3 . The method as claimed in claim 1 , wherein the method is triggered after the first parameter value has been identified in a user's voice input.

4 . The method as claimed in claim 1 , wherein the method is triggered after the first parameter value has been identified in a user's voice input and an action associated with the first parameter value has been executed by the voice dialog system.

5 . The method for creating a voice dialog system from a plurality of voice dialog applications, comprising:

comparing individual voice dialog applications using a predefinable criterion; and

combining the voice dialog applications which satisfy the predefinable criterion, the voice dialog applications being combined to create the voice dialog system.

6 . The method as claimed in claim 5 , wherein

in combining the voice dialog applications, transactions and transaction parameters are respectively combined, and

voice dialog applications are combined if the voice dialog applications have matching parameter values.

7 . The method as claimed in claim 5 , wherein the predefinable criterion is a functional match between the transactions of the voice dialog applications and/or a semantic match between the transaction parameters of the voice dialog applications.

8 . The method as claimed in claim 5 , wherein

the predefinable criterion is a semantic match between the transaction parameters of the voice dialog applications,

to determine the semantic match between two transaction parameters, a comparison is performed of parameter values, and

a semantic match between associated transaction parameters is established or not as a function of the comparison.

9 . The method as claimed in claim 5 , wherein

the predefinable criterion is a functional match between the transactions of the voice dialog applications,

to determine the functional match between two transactions, the grammars associated with the transactions are compared with each other, and

a functional match between two transactions is established or not as a function of the comparison.

10 . The method as claimed in claim 5 , wherein

the predeterminable criterion is a match in vocabularies of the voice dialog applications.

11 . The method as claimed in claim 5 , wherein

when the voice dialog applications are combined, transactions are combined, and

the transactions combined in the voice dialog system are stored in a common transaction database.

12 . The method as claimed in claim 5 , wherein

when the voice dialog applications are combined, transaction parameters are combined, and

the transaction parameters combined in the voice dialog system are stored in a common transaction parameter database.

13 . The method as claimed in claim 5 , wherein

when the voice dialog applications are combined, grammars are combined, and

the grammars combined in the voice dialog system are combined in a common grammar database.

14 . A system to generate a context-based voice dialog output in a voice dialog system having transactions, each transaction having transaction parameters, each transaction parameter having a plurality of possible parameter values, comprising:

an allocation unit to allocate a first parameter value to a transaction parameter of a first transaction;

a matching unit to thematically match the first parameter value with a matching possible parameter value of a second transaction parameter of a second transaction;

a determination unit to determine a second parameter value for a third transaction parameter of the second transaction; and

a generation unit to generate a voice dialog output which comprises at least the first parameter value and the second parameter value.

15 . The system to create a voice dialog system from a plurality of voice dialog applications, comprising:

a comparison unit to compare individual voice dialog applications using a predefinable criterion; and

a combination unit to combine the voice dialog applications which satisfy the predefinable criterion, the voice dialog applications being combined to create the voice dialog system.
