Abstract

Disclosed are an auto attendant system and its method and a call forwarding method using a speech recognition. The auto attendant system according to the invention includes first storing unit for storing information on a subscriber, a first call processing unit for receiving a recognizable name of the subscriber to be communicated with from a user to transfer the same to first speech recognizing unit, and searching the information on the subscriber from the first storing unit to connect a call to a destination number of the subscriber based on the searched information on the subscriber, and first speech recognizing unit for transferring the result of the recognized speech to the first call processing unit by recognizing the speech transferred from the first call processing unit.

Claims

1. An auto attendant system using a speech recognition, comprising:

first storing means for storing information on a subscriber;

a first call processing means for receiving a recognizable name of the subscriber to be communicated with from a user to transfer the same to first speech recognizing means, and searching the information on the subscriber from the first storing means to connect a call to a destination number of the subscriber based on the searched information on the subscriber; and

first speech recognizing means for transferring the result of the recognized speech to the first call processing means by recognizing the speech transferred from the first call processing means.

2. The auto attendant system of claim 1, further comprising:

second storing means for storing information on a call forwarding;

second call processing means for receiving an intention for a call forwarding of calls to the subscriber, a recognizable name of the subscriber and new information on a call forwarding through speech to transfer the same to second speech recognizing means, receiving the result of the recognized speech from the second speech recognizing means, searching the information on call forwarding of the subscriber from the second storing means to change the same to the information on the new call forwarding, and connecting calls to the subscriber based on the changed information on the call forwarding; and

second speech recognizing means for recognizing the speech transferred from the second call processing means to transfer the result of the recognized speech to the second call processing means.

3. An auto attending method applicable to an auto attendant system, comprising the steps of:

a) receiving a recognizable name of the subscriber to be communicated with from the user for recognition of the inputted name; and

b) connecting a call to the destined telephone number of the subscriber based on the recognized name and stored information on the subscriber.

4. The auto attending method of claim 3, further comprising the step of c) receiving the recognizable name of the subscriber through auxiliary input means according to a selection of the user to connect the call to the destined telephone number of the subscriber based on the inputted information and the stored information on the subscriber.

5. The auto attending method of claim 3, wherein the step a) includes the steps of:

a1) receiving the recognizable name of the subscriber to be communicated with from the user through speech, and searching information on the subscriber by recognizing the inputted recognizable name through speech; and

a2) receiving and recognizing recognizable names of higher concepts until the recognizable name of the subscriber becomes unique, if the searched result in the step a1) finds a plurality of subscribers corresponding to the recognizable name through speech.

6. A call forwarding method applicable to an auto attendant system, comprising the steps of:

a) receiving and recognizing an intention for a call forwarding, a recognizable name and new information on a call forwarding of a subscriber who desires a call forwarding from the subscriber through speech; and

b) searching stored information on a call forwarding of the subscriber based on the recognized intention for a call forwarding and the recognizable name of the subscriber, changing the searched information to the new information on a call forwarding, and connecting calls to the subscriber by using the changed information on a call forwarding.

7. The call forwarding method of claim 6, further comprising the step of c) receiving the intention for a call forwarding, the recognizable name of the subscriber and the new information on a call forwarding through auxiliary input means according to a selection by the subscriber, searching the stored information on a call forwarding of the subscriber based on the inputted intention for a call forwarding and the recognizable name of the subscriber, changing the searched information on a call forwarding to the new information on a call forwarding, and connecting calls to the subscriber based on the changed information on a call forwarding.

8. The call forwarding method of claim 6, wherein the step a) includes the steps of:

a1) receiving and recognizing the intention for a call forwarding and the recognizable name of the subscriber through speech from the subscriber who desires a call forwarding, and searching the stored information on a call forwarding of the subscriber; and

a2) receiving and recognizing recognizable names of higher concept until the recognizable name of the subscriber becomes unique, if the searched result in the step a1) finds a plurality of subscribers corresponding to the recognizable name through speech.

9. A computer readable recording medium containing a program for executing an auto attending method applicable to an auto attendant system, the method comprising the steps of:

a) receiving a recognizable name of a subscriber to be communicated with a user from the user, and recognizing the inputted recognizable name; and

b) connecting calls to the subscriber to a destination telephone number of the subscriber based on the recognized recognizable name and the stored information on the subscriber.

10. A computer readable recording medium containing a program for executing a call forwarding method applicable to an auto attendant system, the method comprising the steps of:
