Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to telephone switching systems.

[0002]

2. Description of the Related Art A conventional telephone exchange system connects to a destination in response to a dial from a telephone.

Next, a conventional example will be described with reference to the drawings.

FIG. 4 is a flow chart for explaining the operation of a conventional example.

In the operation of the telephone exchange system shown in FIG. 4, in operation step S17, if the telephone number of the other party to call is unknown, the telephone number must be checked by some method as shown in operation step S18. .

[0006] As a method of this investigation, a telephone number book, a memo pad, a business card, etc. created by an individual are often referred to.
When the telephone number of the other party is known, all the number of digits of the number are dialed in operation step S19, or if the number is registered in the telephone which can be shortened, the shortened dialing is performed.

After this, a call is started as shown in operation step S10. Thus, when the telephone number of the other party is not remembered, it is necessary to search for the telephone number of the other party or the speed dial number.

[0008]

However, in such a conventional telephone exchange system as described above, when a person searches for a telephone number, it is necessary to create a personal telephone number book or a memo pad. Generally, as the number of records increases, it takes more time to search and the number of misreading numbers increases.
Even in dialing, an error occurs because it is performed by a human, and even a telephone having a speed dial function cannot be used in another telephone.

[0009]

SUMMARY OF THE INVENTION The telephone exchange system of the present invention records a foresee destination name and a corresponding telephone number,
A storage unit that is held, a voice recognition unit that recognizes the destination name of the telephone by the voice input from the telephone and converts it to a character string, the converted character string and the destination name that is stored in the storage unit And a dialing unit for performing dialing on the basis of the extracted telephone number.

[0010]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In the telephone exchange system shown in FIG. 1, the telephone 1 has a display section 11 and a button section 12 as well as a function of making a call. The display unit 11 displays information (telephone destination name, destination telephone number, etc.) from the exchange 2. Button part 1
2 inputs a telephone number or switching to a voice recognition dial mode.

The exchange 2 includes a control unit 21 and a voice processing unit 2.
2, a storage unit 23, a dialing unit 24, and the like.

The control unit 21 includes a voice processing unit 22 and a storage unit 2.
3. The tire ring unit 24 is controlled to give an operation instruction for each function.

The voice processing unit 22 uses voice as input data,
It is analyzed and used as coded data.

The storage unit 23 records and holds the previously encoded voice data (destination name) and the telephone number of the destination.

The dialing unit 24 performs a dialing operation based on the telephone number of the other party retrieved from the storage unit.

Next, the operation of the embodiment shown in FIG. 1 will be described.

FIG. 2 is a flow chart for explaining a dialing operation by voice recognition.

First, in operation step S1, it is judged whether or not the receiver goes up, and if the receiver goes up, operation step S2.
Then, it is determined whether the first button pressed is a predetermined button for switching to the voice recognition dial mode.

When the button for the voice recognition dial mode is pressed, the control unit 21 switches the processing to the voice recognition mode in operation step S3. If the specific button has not been pressed, the operation in the normal manual dial mode is performed in operation step S9.

When the voice recognition code is entered in operation step S3, the receiver's name is input by voice from the receiver in operation step S4.

The input voice data is processed in the operation step S.
In step 5, the voice processing unit 22 recognizes the result, and as a result, the character string is converted and output. The encoded telephone destination name is compared with the destination name 251 in the storage unit 23, and the matching destination telephone number 252 is obtained in operation step S6.

The destination name and the destination telephone number obtained here are
The message is displayed on the display unit 11 of the telephone 1 and the telephone caller is prompted to confirm the dialing destination in operation step S7.

As soon as the display operation ends or immediately before the destination telephone number is extracted, dialing is performed to the destination telephone number in operation step S8.

However, at any time when the receiver is placed, all processing is terminated.

When the dialing is completed, the call is switched to a normal telephone call in operation step S10.

FIG. 3 is a flow chart for explaining the registration operation of the destination name and the destination telephone number in the storage unit 23.

The recording format in the storage unit 23 is one party's name and one party's telephone number. The destination name 251 in FIG. 1 is information that serves as a key at the time of retrieval, and is obtained by encoding the destination input by voice as ANK characters. The destination telephone number 252 is a number for dialing.

In the registration operation, it is judged in operation step S1 whether or not the handset is picked up, and if the handset is picked up, whether or not the first button pressed in operation step S11 is a specific button for registering destination information. to decide.

Here, when the specific button is pressed, registration processing of the partner information is performed. If the specific button is not pressed, the operation of the normal telephone mode is performed in operation step S16.

Next, in the other party information registration process of operation step S4, first, the other party is input by voice through the handset, and when the other party is finished saying in operation step S12, a specific button for separating the data (hereinafter, Button and description).

Next, in the operation step S13, the number of the telephone destination is input by the button section 12, and after inputting, the delimiter button is pressed in the operation step S14. The destination telephone number is recorded in the storage unit.

Finally, in step S7, the destination name and telephone number are displayed on the display unit 11 for confirmation, and the process is completed.

However, when the receiver is placed, all processing is terminated at any time.

In the embodiment described above, the telephone 1 is provided with the display unit 11, but in the case of a telephone without the display unit 11, the telephone number is displayed on the display unit 11 at the time of registration and dialing of the other party. Instead of the display operation, voice synthesis may be performed in the voice processing unit 22, and voice registration and dialing confirmation may be performed.

[0037]

The telephone exchange system of the present invention has the following effects by adding the voice recognition function.

1. The telephone number of the other party is recorded in the exchange, and the telephone number of the other party is automatically searched just by saying the other party, so it does not take time to search the telephone number.

2. Since dialing is automatically performed based on the telephone number in the exchange, no error occurs in dialing.

3. Since the telephone number of the other party is recorded in the exchange, dialing can be performed not only by a specific telephone but also by any telephone connected to the exchange just by saying the other party.
