Voice dialog system with reject avoidance process

1. A process for operating a voice dialog system that can be controlled over a telecommunications link by a communications terminal, the process comprising the steps of:

transmitting a first or second speech element with the communications terminal;

receiving the first or second speech element with a receiving unit of the voice dialog system;

filing the first or second speech element in a memory of a processing unit;

converting the first or second speech element into text by a speech-to-text unit;

transmitting a service promise to the communications terminal after conversion of the first or second speech element into text;

breaking the telecommunications link and then analyzing the first or second speech element for statement content with the processing unit by

examining the converted speech element for the occurrence of at least one predetermined term, and,

if the term is found, assigning the term to a predetermined topic;

establishing a telecommunications link to the communications terminal with the voice dialog system; and

connecting the communications terminal to a service, a service representative, or the voice dialog system.

2. The process as claimed in claim 1 , further comprising the steps of:

before converting the first speech element, comparing the first speech element to a speech element filed in a memory assigned to the processing unit; and

if the system is unable to interpret the first speech element, converting the first speech element into text.

3. The process as claimed in claim 1 , wherein the first speech element is a voice message comprising several spoken words.

4. The process as claimed in claim 1 , further comprising the step of:

before converting the first speech element, comparing the first speech element to a speech element filed in a memory assigned to the processing unit; and if the system is unable to interpret as an acceptable dialog command,

transmitting the second speech element by the communications terminal and

converting the second speech element into text.

5. The process as claimed in claim 4 , wherein the second speech element is a voice message comprising several spoken words.

8. A voice dialog system for carrying out the method of claim 1 and that can be controlled over a telecommunications link by a communications terminal, the system comprising:

a receiving unit by means of which a speech element transmitted from the communications terminal can be received,

a speech-to-text unit that can convert the speech element into text, and

a processing unit for analyzing the speech element for statement content, having a memory in which the speech element can be filed, and being set up to analyze the received speech element after the telecommunications link is broken, the voice dialog system being configured to transmit a service promise to the communications terminal after conversion of the first or second speech element into text.
