Abstract: A method and a system for person/speaker verification via different communications systems. The system may include a control logic (SL) having access to a voice-controlled dialog system (DS) having verification dialogs stored for querying, a biometrics customer profile (BK), in which the personal biometric data of customers are stored and a provider database (PD), which contains information regarding protected database areas and services in conjunction with the biometric methods authorized for verification. The method for person/speaker verification is designed to ascertain, transmit, analyze and evaluate via telecommunications systems the different personal biometric data that are suitable to establish unequivocally the access authorization of a customer.

Abstract: In a method for operating a global, virtual a call center having operators working all over the world, in response to a call from a customer, data suitable for identifying the customer and allocating him or her to a customer group are collected and stored. These data are compared using a search routine to stored data of the operators logged on for the call center. As a result, the customer is automatically connected by the call center server to the web browser of the workstation system of the operator selected for the customer, at the same time all of the data collected for the customer being displayed on the web browser window of the operator's monitor. For international call centers, in particular, the method improves communication between the customer and the operator.

Abstract: The invention relates to a method for enhancing recognition probability in voice recognition systems. According to the inventive method, selective post-training of the already stored homonymic term is carried out after inputting a term to be recognized. This makes it possible to improve the speaker-dependent recognition rate even in environments with prevailing acoustic interference.

Abstract: The present invention is directed to a method for the voice-operated identification of the user of a telecommunications line in a telecommunications network in the course of a dialog with a voice-operated dialog system. In accordance with the present invention, utterances spoken by a caller from a group of callers limited to one telecommunications line are used during a human-to-human and/or human-to-machine dialog to apply a reference pattern for the caller. For each reference pattern, a user identifier is stored which is activated once the caller is identified, and, together with the CLI and/or ANI identifier of the telecommunications line, are made available to a server having a voice-controlled dialog system. On the basis of the CLI, including the user identifier, data previously stored for this user are ascertained by the system and made available for the dialog interface with the customer. The method of the present invention is preferably used for voice-controlled dialog systems.

Abstract: One variant from a large number of possible services and/or service combinations is made available to the customer via a dialogue of human-machine interaction: a variant which the customer needs to solve his/her problem or to comply with his/her service request. In the process, it is checked whether the customer has access to the terminal configuration required for this variant and verified that the customer's terminal configuration supports the service and/or service combination concerned. For the customer's access to the calling card service, cards of completely different types, personal phone card, prepaid card, “call home” card, etc., are admitted. The type of calling card defines the customer's access authorization to the various possible services and/or service combinations, as well as the manner of billing those services. The present invention is suited for increasing the degree of automation of the services offered by calling card providers.
