Abstract

PURPOSE: A digital portable phone using voice recognition is provided to respond to the phone by making voice upon the receipt of the phone. CONSTITUTION: A control part in a phone response method by voice recognition sets up a voice recognition mode upon the receipt of the phone. Thereafter, the control part analyzes an audio signal inputted from the microphone to form a call line. In case that the analyzed voice signal is identical to the voice signal for forming the call line, a user is able to speak over the phone.

Description

CALL ANSWERING METHOD BY VOICE RECOGNITION IN DIGITAL PORTABLE TELEPHONE}

The present invention relates to a telephone answering method in a digital portable telephone, and more particularly, to a telephone answering method capable of receiving a voice call when an incoming call is received from the portable telephone.

In general, when a digital portable terminal receives an incoming tone (Alerting Tone) and notifies a user to answer a call, the user opens a flip or presses a predetermined key provided outside the terminal to form a call path. You can make a call.

Therefore, a user of a digital portable terminal has a problem in that when a call is received, a call must be opened or a button must be pressed to make a call and the call is disconnected if it takes a long time to answer.

Accordingly, an object of the present invention is to provide a telephone answering method capable of answering a call by voice of a voice when a call is received from a digital portable wireless terminal.

In the method of answering a call by voice recognition in a digital portable telephone of the present invention for achieving the above object, a process of switching to a voice recognition mode when there is an incoming call, and switching to the voice recognition mode and then calling a call through a microphone And a process of performing a call by forming a voice signal for forming a voice signal and a voice signal for forming a call path.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Also, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those of ordinary knowledge in Esau. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a digital portable telephone to which the present invention is applied.

Parts not directly related to the gist of the present invention, such as a radio frequency (RF) unit and a dual tone multi frequency (DTMF) unit, are not shown and described.

The analog voice signal input through the microphone 30 is analog / digital (hereinafter referred to as A / D) conversion unit 20 and pulse code modulation (Pulse Code Modulation: PCM) in digital form. Is converted into a signal. The PCM signal is transmitted to the voice encoder 45, and the voice encoder 45 compresses the PCM signal and outputs packet data. As the voice encoder 45, for example, an 8K QCELP for a CDMA digital portable telephone and an RPE-LTP for a GSM digital portable telephone can be used.

The packet data output from the voice encoder 45 is transferred to the microprocessor 50 which collectively controls the overall operation of the digital portable telephone. The first memory 60 is a nonvolatile memory (eg, flash memory, EEPROM), and stores programs and initial service data that collectively control the overall operation of the digital portable telephone. The second memory 65 is a volatile memory (RAM), and temporarily stores various data according to the operation of the digital portable telephone. The speech recognition unit 85 outputs characteristic data for arbitrary speech. The characteristic data consists of 20 bytes per second and is a frequency characteristic, a signal size, a function of magnitude change, and the like. The voice recognition unit 85 may be implemented in hardware or software. If the voice recognition unit 85 is implemented in software, the voice recognition unit 85 may be stored in the first memory 60, which is already included in the digital portable telephone. The control unit 50 controls the operation of a known digital portable telephone and transfers packet data output from the voice encoder 45 to the voice recognition unit 85 when there is an incoming call, and the voice recognition unit 85. Control to perform a predetermined operation (e.g., forming a currency) as a result of recognition according to the characteristic data index and the difference value. The key input unit 55 has a plurality of keys, such as keys for setting various modes, numeric keys for dialing, and function mode voice registration keys. The flip state detector 95 senses an on / off state of a flip (not shown) to cause the controller 50 to determine whether to enter the voice recognition mode. The display unit 90 displays various situations as a result of operations unique to the digital portable telephone and voice recognition according to an embodiment of the present invention.

2 is a control flowchart for answering a call by voice when there is an incoming call according to the present invention.

2, in step 101, the controller 50 checks whether there is an incoming call, and proceeds to step 102 if there is an incoming call. In step 102, the controller 50 switches to the voice recognition mode and supplies power to operate the microphone 30 and the A / D converter 20. Then, in step 103, the controller 50 checks whether a voice signal is input from the microphone 30, and if it is not input, proceeds to step 104. In step 104, the controller 50 checks whether a key signal is input from the key input unit 55 or a flip is opened from the flip state detection unit 90. If the key signal or flip is opened, the controller 50 proceeds to step 105. In step 105, the controller 50 performs a call by forming a call path. However, when the voice signal is input in step 103, the process proceeds to step 106 to analyze the voice signal input from the microphone 30 to form a call path and perform a voice call. In this case, the input voice signal may be a signal such as a call or a call start. In this manner, the call is performed and the call is terminated in step 107. When the call ends, the call is blocked and the operation is terminated.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention enables a mobile phone to automatically make a call when a voice is spoken when a call is received, so that a call can be made when a call is received. There is an advantage that does not have to.
