5 is a flowchart illustrating an operation process of a temporary embodiment of the present invention.

In order to listen to the contents of the electronic book stored in the computer, the user inputs a predetermined electronic book driving key in the keyboard 307 of the handset 300 (S501). When the electronic book drive key is input, the corresponding drive control data signal is transmitted to the handset RF module through the voice processor.

The antenna 301 is wirelessly transmitted to the station 200 through the 302. The antenna 205 of the station receives a radio signal, extracts a voice signal and a control data signal from the station RF module unit 204 (S502), and transmits the control data signal to the A / D converter 206, where the control data is computer control data. The central processing unit 207 causes the switching unit 202 to connect the audio processing unit 203 and the computer 100 (S503) (S505), and if it is not a computer control data signal, i.e., data for call connection with a public telephone network. Voice processing unit

203 and the trunk line interface 201 are connected to the public telephone network (S503) (S504).

When the switching unit 202 is controlled by the central processing unit 207 to connect the transformer unit 209 and the audio processing unit 203 of the station 200, and under the control of the central processing unit 207, the control data signal is input to the computer via the interface 208, 108, The central processing unit 101 of the computer 100 detects whether the control data is for the execution of the electronic book (S506). If the control data is not for the execution of the electronic book, the computer 100 executes a command according to the control data (S507). . In addition, in the case of control data for executing the electronic book, the central processing unit 101 drives the electronic book to drive the driving processor 103 to read the contents stored in the storage unit 102 of the electronic book by the speech synthesis processor 104 to synthesize the speech (S508). (S509). The synthesized sound is transmitted to the sound card 105 under the control of the central processing unit 101, and the sound card 105 transmits a voice signal to the transformer unit 209 of the station 200 (S510). Transmit to 203, amplify and filter the voice signal, and transmit it to the station RF module unit 204 to wirelessly transmit from antenna 205 to handset 300.

(S510). The antenna 301 of the handset 300 demodulates the voice signal transmitted from the radio frequency band by the handset RF module unit 302 and transmits the audio signal to the voice processor 303 to reproduce the voice through the receiver 308 (S511). If the ring or call signal (arc signal) of the telephone is input through the CO line interface 201 or from the handset during such playback (S512), the ring and call signal are input to the central processing unit 207, and the central processing unit 207 switches. By controlling the unit 209 so that the CO line interface 201 and the voice processing unit 203 are connected and connected, the handset 300 serves as a general telephone. If the end key is input to end the voice signal listening operation for the e-book, the process ends (S513).

Various functions can be used in the electronic book driving (S508) process. The computer 100 detects that the end key of the handset 300 is input, and causes the e-book driving processor 103 to store the address of the last part synthesized by the voice synthesis processor 104 and execute the e-book again in the central processing unit 101. If an execution key is inputted, the voice is synthesized after the last part of the stored key to listen.

In addition, it is a general example that a plurality of different contents are stored in the electronic book. 6 illustrates an example in which a list of contents is displayed on a monitor of the computer 100.

In such a case, the user of the handset 300 can freely move the contents list by inputting a designated key, and can also check the list by voice by listening to the voice synthesizer corresponding to the list. After checking the list, you can listen to the voice of the contents by selecting a specific list using the designated key.
