Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, specific details such as names of specific menus 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 who have knowledge. 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 illustrates a configuration of a voice recognition telephone according to an embodiment of the present invention.

The display unit 10 displays a voice recognition state, various operation processing conditions, and the like. The key input unit 15 is a user interface means and includes a key for selecting a menu or various functions or a numeric key for dialing.

The analog type audio signal input through the microphone 30 is analog code to digital pulse code modulation (hereinafter referred to as PCM) through an analog / digital converter (hereinafter referred to as A / D). Is converted into a signal. The PCM signal is transmitted to the voice encoder 75 through the first pass of the first switch 50a of the switch unit 50 or the second path to the microprocessor 20.

The connection state of the first switch 50a is changed by a first switch control signal generated by the microprocessor 20. The common terminal of the first switch 50a is connected to one input port of the microprocessor 20 when the first switch control signal is high, for example, and to the input terminal of the voice encoder 75 when low. In the latter case, the first path is a path formed when the A / D converter 40 and the voice encoder 75 are connected to perform a voice registration or recognition function.

The second switch 50b is turned on or off by a second switch control signal generated by the microprocessor 20. The second switch 50b is turned on when the second switch control signal is high, for example, and connects an output port of the microprocessor 20 and an input terminal of the voice encoder 75, and turns it off when it is low. And disconnects a third path between an output port of the microprocessor 20 and an input terminal of the voice encoder 75.

The first and second switches 50a and 50b are for storing memos or reading memos, respectively.

The speech encoder 75 outputs packet data by compressing a PCM signal for speech for recognition. Packet data output from the voice encoder 75 is transferred to the microprocessor 20 which collectively controls the overall operation of the telephone.

The menu memory 55 stores a predetermined menu display control program according to an embodiment of the present invention. Examples of the menu include "save voice memo", "read voice memo", and the like.

The voice registration / recognition memory 60 is a memory used to register a voice and process the voice recognition function. The memo memory 70 is for storing a voice itself, which says contents to be memorized when there is a need for memo during a call.

The microprocessor 20 transfers the voice data read from the memo memory 70 (hereinafter referred to as voice memo data) to the voice encoder 75, and the voice encoder 75 converts the voice memo data into a PCM signal and converts it into digital / analog (digital) data. to analog: hereinafter referred to as D / A.) The PCM signal input to the D / A converter 85 is converted into an analog form, and then amplified by the speaker 80 and output as an audible sound.

The timer 25 is built in or external to the microprocessor 20 and is used to set a time for taking notes.

The microprocessor 20 also checks the remaining capacity of the memory at some point, and calculates the amount of time it can store voice memo data with that capacity. The operation of the timer 25 is controlled based on the calculation result.

2 is a flowchart illustrating a voice memo process according to an embodiment of the present invention.

In step 2a, the microprocessor 20 displays an initial menu on the display unit 10. In operation 2b, the key input unit 15 is scanned to check whether a voice memo storage item is selected by the user. At this time, if the selection of the voice memo storage item is detected, it is checked whether the call is 'in a call' in step 2c. If the check result is 'call', in step 2d, the capacity of the currently available memory is checked. The amount of time that the voice memo data can be stored is calculated using the capacity. For convenience, the calculated time is referred to as memo time.

After performing step 2d, in step 2e, the microprocessor 20 compares the memo available time with a designated time. The specified time is selected when the user selects a voice memo storage item. As a result of the comparison, if the memo available time is shorter than the designated time, a message is displayed on the display unit 10 in a menu form to determine whether to delete previously stored contents in step 2f. Thereafter, in step 2g, the microprocessor 20 scans the key input unit 15 to check whether a positive or negative response (eg, a "Yes" or "No" key) is input by the user. At this time, if the input of the positive response is detected, the timer 25 is operated for the predetermined time in step 2h. On the other hand, if a negative input is detected, in step 2i, the microprocessor 20 operates the timer 25 only for the maximum time available. After performing step 2h or 2i, the microprocessor 20 proceeds to step 2j to generate a first switch control signal in a high state and a second switch control signal in a low state so that a user's voice input through the microphone 30 is memo. Passed to memory 70 for storage. However, after all the time set in the timer 25 has elapsed, a unique voice recognition function should be performed. The first switch control signal is generated in a low state and the second switch control signal is generated in a high state. Voice input through 30 is passed to voice encoder 75.

If the selection of the voice memo storage item is not detected in step 2b, it is checked whether the read voice memo item is selected in step 2k. In response to the selection of the read voice memo item being detected, the microprocessor 20 causes the display unit 10 to display the previously stored voice memo item in step 2l. In step 2m, the key input unit 15 is scanned to detect whether an item is selected by the user. In this case, when the selection of an item is detected, the microprocessor 20 reads the voice memo data of the corresponding item from the memo memory 70 and transmits it to the voice encoder 75 in step 2n. In this case, the voice encoder 75 converts the voice memo data into a PCM signal and transmits the voice memo data to the D / A converter 85. The PCM signal input to the D / A converter 85 is converted into an analog form, and then through the speaker 80. Amplified and output as an audible sound. This allows the user to listen back to the stored voice memo data.

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 is convenient because it is not necessary to use a separate device or handwriting on paper by taking a memo in a manner of storing the voice in the phone itself when a memo is required during a call and later listening it when necessary.
