Description

A auto talking method by voice recognition in a mobile telephone

The present invention relates to an automatic call method in a mobile phone, and more particularly, in a mobile phone in which a call is opened so that a call can be made from a point in time when a voice identical to a stored voice is recognized when a call is received in an automatic call mode. It is an automatic call method by voice recognition.

With the development of electronic communication technology and entering the information society, the need for rapid and frequent information exchange has been rapidly developed and personal mobile communication systems have been developed. The representative method of the personal mobile communication system is a cellular communication method, which divides a certain area into a predetermined number of cells (for example, takes a seven cell method), and then installs a base station for communication relaying in each area. Each base station is connected to a control station connected to a public communication network, and then a wireless terminal (sometimes called a cellular phone) that randomly passes through a plurality of cell areas through a communication relay between a base station or a control station in each cell is used. Even if it is present, the call between the subscribers of the public telecommunication network or the wireless terminal is enabled.

The cellular phone, which is one of such mobile phones, is shown in FIG. 1, the duplexer 10, the receiver 20, the frequency synthesizer 40, the microprocessor 50, the first memory 60, The second memory unit 70, the third memory unit 80, the key input unit 90, the liquid crystal display unit 100, the voice processing unit 110, the speaker 120, the microphone 130, and the voice recognition unit 140. And a flash memory 150.

That is, the receiver 20 receives and outputs the call signal and the call message of the other party applied through the duplexer 10 from the antenna ANT, and the transmitter 30 processes the call signal processing and the phone message of the authorized user by the duplexer. It transmits via 10 and antenna ANT.

The frequency synthesizer 40 synthesizes and supplies a transmission frequency to the transmitter 30, and simultaneously synthesizes and supplies a reception frequency applied from the receiver 20, and the microprocessor 50 controls the overall operation of the cellular phone. The first memory unit 60 stores an operation program of the microprocessor 50, the second memory unit 70 stores a signal processing program of the microprocessor 50, and the third memory unit 80. Stores information such as Korean and special characters and a phone number input by the user.

The key input unit 90 includes a plurality of keys for inputting various indication information into the microprocessor 50, and the liquid crystal display unit 100 controls the reception and transmission of the cellular phone under the control of the microprocessor 50. Indicates.

The voice processor 110 digitizes or analogizes a voice signal applied from the microprocessor 50 or the microphone 130 and outputs the digital signal. The speaker 120 outputs a signal applied from the voice processor 110 to the outside. The microphone 130 outputs the voice signal input by the caller to the voice processing unit 110 and the voice recognition unit 140.

The voice recognition unit 140 processes the voice signal input from the microphone 130 and patterns the voice signal and outputs the patterned voice signal to the flash memory 150 and the microprocessor 50. The flash memory 150 stores voice commands for operating the cellular phone.

The operation of the cellular phone having the above configuration is as follows.

The reception signal of the other party input through the antenna ANT and the duplexer 10 is received by the receiver 20 and input to the microprocessor 50, and the received signal input to the microprocessor 50 is the voice processor 110. ) Is converted into an analog signal and output to the speaker 120.

On the other hand, the transmission signal is collected through the microphone 130 is converted into a digital signal in the voice processing unit 110 and then transmitted to the transmission unit 20 through the microprocessor 50 through the duplexer 10 to the antenna (ANT) Is output.

In addition, a voice recognition function allows a user to dial by voice or to store a number corresponding to a specific voice (for example, "home", "company", etc.), and to open a call path when the specific voice is spoken.

The cellular phone is equipped with an automatic call function, which is a convenient function that allows a call without opening a flip when there is a flip and without pressing any key when there is no flip.

Flow chart of this automatic call function is shown in FIG.

That is, when the user sets the automatic call mode in the key input unit 90, when a call request using a trunk line or a mobile phone is generated and a ring signal is detected, the microprocessor 50 determines that the current call mode is in the automatic call mode. Determine the cognition.

If it is determined that the call is not in the automatic call mode, the user is notified of the incoming call in the bell / melody / vibration mode until the user opens the flip or presses a random key to answer the call.

However, in the automatic call mode, if the user does not answer the call while the bell / melody / vibration occurs for a certain number of times / a certain time, it automatically opens a call path so that the call can be made. Of course, if a user opens a flip or presses any key before a certain number of times or a predetermined time elapses, the call can be made.

However, such a conventional automatic call method is particularly used in the case of replacing the hands-free with hands-free earphones or the cellular phone in a pocket or a bag and receiving a walk. If the caller does not recognize the melody or is in a state where the call is temporarily made without any other business, there is a problem of discomfort because the caller hears the surrounding noise.

The present invention has been made to solve the above-described problems, the purpose of which is to store the voice of a specific phrase input by the user by using the voice recognition function, and the call path from the point of time that the voice of the phrase is recognized It is an object of the present invention to provide an automatic call method by voice recognition in a mobile phone that allows an automatic call to be established.

In order to achieve the above object, an automatic call method using voice recognition according to the present invention includes a process of determining whether a ring signal is detected, a process of determining whether an automatic call mode is set when a ring signal is detected, and an automatic call mode. Recognizing the voice of a specific phrase to perform an automatic call, and in the normal mode other than the automatic call mode, to announce the incoming call in the selected mode of bell / melody / vibration and to open the call path by recognizing the flip open or key input Characterized in that made.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the exemplary embodiment of the present invention, a mobile phone (cellular phone) adopted to implement an automatic call method using voice recognition has the same configuration as the cellular phone of FIG. 1 having a conventional voice recognition function.

That is, the duplexer 10, the receiver 20, the frequency synthesizer 40, the microprocessor 50, the first memory unit 60, the second memory unit 70, the third memory unit 80, the key An input unit 90, a liquid crystal display unit 100, a voice processing unit 110, a speaker 120, a microphone 130, a voice recognition unit 140, and a flash memory 150 are provided.

To perform the automatic call in the cellular phone of such a configuration by the voice recognition, the voice of a specific phrase for the automatic call using the automatic call voice storage key provided in the key input unit 90 (eg, "hello" or "yes, ○○○ ", etc.) should be saved in advance.

To this end, after the user presses the automatic call voice storage key provided in the key input unit 90, the microphone 130 speaks a voice for an automatic call such as "Hello" or "Yes, ○○○". The voice collected at 130 is input to the voice recognition unit 140 to extract and pattern the feature of the voice and store the data in the flash memory 150.

When the user selects the automatic call mode in the key input unit 90 while the voice for the automatic call is stored, the user can automatically call by voice recognition when a call is received.

Next, the automatic call process by voice recognition according to a preferred embodiment of the present invention in the state of being ready for the above-described automatic call will be described in detail with reference to the flowchart of FIG. 3.

First, the microprocessor 50 determines whether a ring signal is detected (S100).

If it is determined that the ring signal is detected, it is determined whether the call mode is set (S110).

If it is determined that the normal mode, not the automatic call mode, the incoming call mode set by the user is notified that the call is received (S120).

That is, if the bell mode is set, ring the bell to notify the incoming call, if the melody mode outputs the specified melody, and in the vibrate mode not shown, but the vibration means to operate the call notification.

After notifying you of incoming status, if the flip open (if flipped) or any key (if normal) is recognized, open a call to make a call.If the flip open or any key is not recognized, wait for the call to be recognized. (S130, S140).

However, if it is determined that the automatic call mode, the voice recognition is performed for the automatic call by voice recognition (S150). Therefore, the voice collected by the microphone 130 is a voice recognition in the voice recognition unit 140, the feature is extracted and is converted into data that can be recognized by the microprocessor 50 is output.

Then, the microprocessor 50 determines whether there is a recognized voice based on the data input from the voice recognition unit 140 (S160).

If there is a recognized voice as a result of the determination, the voice data for the automatic call stored in the flash memory 150 is read to determine whether it is the same as the currently recognized voice (S170).

If the currently recognized voice and the stored voice for the automatic call are the same, a call path is opened to enable the automatic call (S180). If not the same, however, the process proceeds to step S150 for performing voice recognition again.

On the other hand, if there is no recognized voice as a result of the determination of step S160, it is determined whether the flip open or any key recognition (S190). If it is determined that the flip open or any key is recognized, the flow advances to step S180 to establish a call so that the call can be made. Otherwise, the flow returns to step S150 for performing voice recognition.

In other words, in the automatic call mode, if the same voice as the voice for the automatic call by voice recognition stored in the flash memory 150 is recognized, the automatic call is enabled at the recognized time point, and the flip open or any key is pressed. If it is recognized, it will open a currency path.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention as set forth in the claims. Anyone can see it easily.

According to the automatic call method according to the voice recognition of the present invention as described above, the ambient noise is transmitted to the caller by automatically connecting in a state where the user is left in the automatic call mode or the bell / melody / vibration is not recognized. There is an effect that can be prevented.
