For example, in a record edition system the ROM  6 A has stored the waveforms of voices uttered by persons as they are or in the form of coded data. A unit of a waveform relates to a letter, a word or a phrase. In a parameter edition system, the ROM  6 A has stored a plurality of groups of parameters, each group representing a respective one of the waveforms of voices uttered by persons. In a rule synthesis system, the ROM  6 A has stored a plurality of groups of characteristic parameters, each group representing a respective one of small basic units such as a syllable, phoneme or waveform for one pitch extracted from a letter or phoneme symbol string based on phonetic/linguistic rules. It also has stored waveform data representing roars and cries of animals, songs of small birds, etc., and sounds produced in the natural world (such as sounds of winds, blasts, - - - sound effects) in addition to human beings&#39; voices. 
   The read-aloud voice producing unit  13  includes a well-known text voice synthesis system having, for example, a rule synthesis method that converts a text (letters) of book data to voice data. This voice synthesis system includes a sentence analysis unit, a voice synthesis rule unit, and a voice synthesizer. 
   The sentence analysis unit includes a dictionary that has stored many words, pronunciation symbols, grammar information, and accent information. The sentence analysis unit checks a grammatical connection between words in a sentence, analyzes the structure of the sentence while checking sequentially the words of the sentence, starting at its head, for those registered in the dictionary sequentially to separate the sentence into words, and then gets information such as pronunciation symbols, grammar information and accents about the respective words. 
   The voice synthesis rule unit analyzes changes in pronunciation (phonemic rules) including generation of series of voiced consonants, nasalization, and aphonicness caused by pronunciation of connected words, and changes in metrical rules such as shift, loss and occurrence of accents, and determines phonetic symbols and accents to thereby determine voice synthesis control parameters. The voice synthesis control parameters include synthetic units (CVC units) such as, for example, clauses and pauses, and pitches, stresses of and intonation about voices. 
   When the voice synthesis control parameters are determined, the voice synthesis unit synthesizes a voice waveform based on the synthesis units and control parameters stored in the voice data ROM  6 A.

   Operation 
   The inventive electronic book device  1  executes processes corresponding to the respective modes set in the mode setting process. When the power supply is on, the electronic book device  1  is set in the timepiece mode in which the timepiece  12  records the present time, and also waits for a mode switch to be depressed, at which time the mode setting process starts. 
   The CPU  2  determines the kind of the depressed mode switch. When mode switches corresponding to the telephone, timepiece and book modes are depressed, the respective corresponding processes are executed. 
   The telephone, timepiece and book processes in the corresponding modes and a process for selecting and downloading desired book data will be respectively described next: 
   (Telephone Process) 
   The telephone process to be performed to make a telephone call to a person or callee (part 1) and the telephone process to be performed when the book device is called by a person (part 2) will be described next. When the electronic book device  1  makes a telephone call to a person or callee in the telephone process (part 1), the telephone mode switch is depressed. 
   Then, when a desired callee&#39;s telephone number is inputted at the dial unit  3   d , or when a desired callee&#39;s number is selected from among the telephone number data stored in the dial data storage area of the internal RAM  7 , or when the auto dial switch  3 S is operated to dial the book data deliver center HS to thereby to turn on a dial switch (talk switch) of the dial unit  3   d , the communication I/F  9  sends a call signal to the inputted or selected callee. When the callee or the delivery center HS responds to the call signal and the book data device  11  is connected to the callee or the delivery center HS, the telephone call process is executed. 
   In the telephone call process to the callee, the user&#39;s voice inputted to the microphone  1 C is converted by the voice input unit  14  to a digital signal, which is then modulated and sent via the communication I/F  9  to the callee. Then a signal from the callee is received by the communication I/F  9  and delivered to the CPU  2 . This signal is then converted by the voice output unit  15  to a voice signal that is then audibly output from the speaker  1 E or sent from the transmitter  16  to the wearable device  20  to thereby cause the earphones  28  to output a corresponding voice in an appropriate volume. The CPU  2  may display on the display unit  4  telephone call data such as the callee&#39;s telephone number, name and an elapsed communication time during the telephone call. 
   When there arrives an incoming call from an external caller during the use of the electronic book device  1  in the timepiece or book mode, the telephone process (part 2) starts. When the communication I/F  9  detects the arrival of the incoming call and delivers a corresponding detection signal to the CPU  2 , the CPU  2  determines whether the book data is under reproduction at present. If it is, the CPU  2  delivers to the transmission unit  16  a reproduction stop command to stop reproduction of the book data. At this time, the CPU  2  stores data on a position on the book page, where the reading aloud of the book data stopped, in the incoming call register  7   i  of the internal RAM  7 . The CPU  2  also delivers to the transmission unit  16  data to report the arrival of the incoming call. The transmission unit  16  then sends the wearable device  20  the reproduction stop command and the incoming call report command. The wearable device  20  stops reading-aloud or reproduction of the voice output unit  27  and reports the arrival of the incoming call with the aid of the incoming call reporter  23 , based on the received reproduction stop command and incoming call report command, respectively. The arrival of the incoming call is reported, for example, by a predetermined sound or message voice (stored in ROM  25 ) or in vibrations given by the vibrator. The electronic book device  1  may display a message reporting the arrival of the incoming call on the display unit  4 . 
   Then, when the incoming call is responded by depressing the talk switch, the telephone call process starts. When the telephone call ends, the CPU  2  reads out the data on the position o the book page where the reading-aloud of the book data stopped from the read stop register  7   i  of the internal RAM  7  to reopen the read-aloud or reproduction of the book data at that position to thereby restore the normal book mode and to terminate the telephone process (part 2). 
   When no book data is being read aloud or reproduced at the arrival of the incoming call, the arrival of the incoming call is reported. When the incoming call is responded by depressing the talk switch, the telephone call process is performed. When the telephone call is terminated, the timepiece mode is restored to thereby terminate the telephone call process (2). 
   (Timepiece Process) 
   The timepiece process to be performed in the set timepiece mode will be described next. When calendar information such as the present date/time is displayed on the display unit  4 , using the electronic book device  1 , the timepiece mode is set by operating the corresponding mode switch. In more detail, the CPU  2  sets the timepiece mode in the mode data storage area  7   b  of the internal RAM  7 , refers to the present time counted by a time counter  12 , updates data in the time count register  7   h  of the internal RAM  7 , and outputs the present time data to the display driver  5 . The display driver  5  produces the present date/time data, stores same in the display register  7   a  of the internal RAM  7  and displays it on the display unit  4 . 
   As described above, by simple depression of the mode switch the timepiece mode is selected instantaneously to thereby display the present date/time on the display unit  4 . 
   (Book Process) 
   Referring to  FIG. 7 , the processes to be performed by the electric book device will be described next.  FIG. 7  is an overall flowchart illustrating the respective processes performed by the electronic book device, book data delivery center and copyright holder terminal.  FIG. 8  is a flowchart illustrating a process for selecting book data and a reciter image.  FIG. 9  is a flowchart illustrating a process for reading aloud or reproducing book data. 
   Reading aloud or reproducing the book data stored in the electronic book device  1  using voice data stored in the voice data ROM  6 A of the electronic book device  1  will be described. 
   When desired book data selected from among the plurality of book data stored in the external RAM  8  is to be read aloud or reproduced in the electronic book device  1 , the book mode switch is depressed. 
   In response, the CPU  2  reads out all the data related to the books stored in the external RAM  8  and displays the read data on the display unit  4 . For example, as shown in  FIG. 10A , the CPU  2  indicates a message M 2  “Please select a desired book”, all book Nos. and titles such as “1. Book title (a)”, “2. Book title (b)”, . . . and a pointer P to select the desired book. 
   When a book to be reproduced or its title is selected by operating the cursor switch of the input unit  3  or the rotary switch  11 , and the depress switch is then depressed, the CPU  2  reads out book data corresponding to the selected book title from the external RAM  8  and stores the data in the book data storage area  7   d  of the internal RAM  7 . 
   The CPU  2  transfers text data on a first page (cover page) of the read-out book data to the display driver  5 , which produces corresponding data to thereby be displayed on the display unit  4 . The CPU  2  then gives the read-aloud voice producing unit  13  a read-aloud start command, using voice data stored in the voice data ROM  6 A, and performs a process for reading aloud or reproducing the book data in a voice represented by stored relevant voice data. 
   Referring to  FIG. 7 , a process to be performed by the book data delivery center HS for the user to download desired book data from the book data delivery center HS onto the user&#39;s electronic book device  1  will be described next along with data communication performed between the user&#39;s electronic book device  1  and the book data delivery center HS. 
   First, the user of the electronic book device  1  accesses a homepage of the book data delivery center HS, for example, via the Internet  40  and sends a request for delivery of a desired book and the user ID to the delivery center HS (step F 1 ). The CPU  31  of the host server  30  receives these data (step F 2 ), and stores these data in the RAM  31 A In order to display on the electronic book device  1  a book select picture that urges the user to select a desired book, the CPU  31  of the host server  30  sends back the book select picture data (including data related to the book data) to the requesting terminal or the electronic book device  1  (step F 3 ). 
   When the electronic book device  1  receives the book select picture data, it displays on the display unit  4  a book select picture corresponding to the received book select picture data, and then the user selects book data on the book select picture (step F 4  in  FIG. 7A ) to download desired book data from the book data delivery center HS. 
     FIG. 8  is a flowchart of the book data select process to be performed by the electronic book device  1 .  FIG. 10A  illustrates a book select picture to select book data to be downloaded. 
   In order to download the book data, the book select process of  FIG. 8  is performed. When the auto dial switch  3   s  is depressed in the electronic book device  1 , the automatic telephone call unit provided in the communication I/F  9  connects a line automatically from the electronic book device  1  to the book data delivery center HS. The communication I/F  9  sends the book data delivery center HS a request for delivery of desired book data and the sender ID of the electronic book device  1  thereof. When the book data delivery center HS receives these data, it sends back data related to deliverable book data (book titles, author names, publishing company&#39;s names, etc.) to the electronic book device  1 . 
   When the electronic book device  1  receives the book-related data via the communication I/F  9  from the book data delivery center HS, the CPU  2  displays on the display unit  4  a book select picture that contains the book-related data, as shown in  FIG. 10A . 
   The book select picture displayed on the display unit  4  contains a message M 2  to urge the user to select book data to be downloaded: “Please select a desired book”, and all data G 1 , G 2 , G 3  . . . related to deliverable book data. For example, data G 1  related to book No. 1 contains book title (a): “USA CONSTITUTION”; data G 2  related to book No. 2 contains book title (b): “GONE TOGETHER WITH THE SOUND”; and data G 3  related to book No. 3 contains book title (c): “COMIC: EDISON, THE KING OF INVENTORS: (BIOGRAPHY)”. 
   The displayed pointer P can be moved to a position of a desired book title by operating the cursor switch or the rotary switch  11  and a decision switch(not shown) can be operated to select the desired book from the related data. 
   When the desired book is determined (YES in step E 2 ), the CPU  2  stores the book No. of the selected book in the internal RAM  7  (step E 3 ). Simultaneously, the CPU  2  sends a request for delivery of the selected book, the selected book No. and the sender or user ID via the communication I/F  9  to the book data delivery center HS. 
   When the book data delivery center HS receives these data, it reads out from the book data ROM  32  book data (containing a plurality of character images appearing in the book data) corresponding to the selected book No., and the images of the famous persons, etc., as reciters, and sends these data to the electronic book device  1  that sent the sender ID via the Internet  40  to the delivery center. 
   When the electronic book device  1  receives these data, it stores the data in the internal RAM  7   a . Then, the electronic book device  1  displays on the display unit  4  the images of the characters  402  and  403  of the received book data, as shown in  FIG. 10B  (step E 4 ). Then, when a predetermined time elapses, images of reciters N 21 –N 25  are displayed together as shown in  FIG. 11A  (step E 5 ). 
   Then, when a further predetermined time elapses, the electronic book device  1  urges the user to select and allocate desired two of the reciter images N 21 –N 25  to the character images  402  and  403 , respectively, as shown in  FIG. 11B  step E 6 ). 
   Thus, the user selects and decides the desired reciter images (step E 7 ). Then, the book device  1  stores those decided reciter images in the corresponding area  7   g  of the RAM  7  (step E 8 ). For example, when the user selects a reciter image N 22  of the famous persons B from among the reciter images N 21 –N 25  of the famous persons A . . . N of  FIG. 11A  and allocates this reciter image to the character image  402  of “Miss X” appearing in the book data, as shown in  FIG. 11B , the character image  402  for “Miss X” and the reciter image N 22  are stored in corresponding relationship in the area  7   g  of the RAM  7 . Likewise, when a reciter image N 21  of the famous person A is allocated to a character image  403  of “Mr. Y” appearing in the book, the character image  403  for “Mr. Y” and the reciter image N 21  are stored in corresponding relationship in the area  7   g  of RAM  7 . Then, the book data and reciter image selecting process is terminated. 
   Referring back to  FIG. 7 , a process for downloading the book data is performed. To this end, the auto dial switch  3 S of the electronic book device  1  is depressed. In response, the automatic telephone call unit of the communication I/F  9  automatically connects a line from the communication I/F  9  to the book data delivery center HS. The communication I/F  9  then sends a request for delivery of book data and the sender ID of the electric book device  1  thereof to the book data delivery center HS. 
   When the book data delivery center HS receives these data, it sends the book device  1  an acknowledgement of those data and data related to deliverable book data such as book titles. 
   When the electronic book device  1  receives these data via the communication I/F  9 , the CPU  2  of the book device  1  displays these data on the display unit  4 . The book device  1  then sends the book delivery center HS the book No. selected on the book select picture, along with the sender ID of the book device  1  (step F 5 ). 
   When the host server  30  receives those data from the electronic book device  1  (step F 6 ), it stores the data in the RAM  31 A, reads out a message about the acknowledgement of the book No. selected from a message ROM not shown) of the host server  30 , and then sends the message back to the electronic book device  1  (step F 7 ). 
   The electronic book device  1  displays this message on the display unit  4  (step F 8 ). 
   The host server  30  then sends the electronic book device  1  book data for the book No., reciter images, and their voice data selected in the electronic book device  1  (step F 9 ). 
   The electronic book device  1  downloads the book data, reciter images, and their voice data into the book data storage area  7   d , reciter image storage area  7   g  and voice data storage area  7   h , respectively, of the RAM  7  thereof for each book No. (step F 10 ). When this downloading process ends, the electronic book device  1  sends the host server  30  data indicative of completion of the data downloading (step F 11 ). 
   Then, the host sever  30  sends the electronic book device  1  data on bill data about the sum of the price of the book data, reciter images, etc., and a delivery charge cost to download the book data, etc. (step F 12 ). The electronic book device  1  displays this bill data on the display unit  4  (step F 13 ). The electronic book device  1  performs a process for settling accounts with the host sever  30  for the bill data. There are various accounts settling methods. For example, the electronic book device  1  can request a financial institution to pay the host server  30  for the bill (step F 14 ). 
   The host server  30  sends the electronic book device  1  the bill data and informs the copyright holder terminal  30 B of the sale of the electronic book via the Internet  44  (step F 22 ). The copyright holder terminal  30 B receives this information from the host server  30  (step F 23 ). The “copyright holder” referred to here includes an author who created the book data, the famous persons, voice actors/voice actresses, whose images were used as the reciter images, and a managing company that manages the copyright of the reciter images and the right of their likeness. 
   Then, a process for reading aloud and reproducing the book data is performed as shown in  FIG. 9  (step F 14 ), which will be described next. 
   The CPU  2  of the electronic book device  1  determines whether or not the delivered book data stored in the book data storage area  7   d  of the internal RAM  7  is of the cartoon or comic type in the book data reciting or reproducing process. If it is (YES in step D 1 ), the CPU  2  reads out the title, author&#39;s name and contents data from the book data storage area  7   d  and displays those data on the display unit  4  (step D 2 ). Then, as shown in  FIG. 12A  the CPU  2  extracts from the RAM  7  the images  402  and  403  of the characters appearing in the book, their names (Miss X, Mr. Y) included in the book data and the corresponding reciter images N 21  and N 22 , and displays these images on the display unit  4  (step D 3 ). 
     FIG. 12A  illustrates a start of reproduction of comic book data. As shown, a title of a book  401  is displayed as “COMIC: EDISON, THE KING OF INVENTORS (BIOGRAPHY)” along with an image  402  of “Miss X”, character No. 1. Likewise, an image  403  of Mr. Y, character No. 2, is displayed. Reciter images N 21  and N 22  stored in the RAM character storage area  7   g  and selected by the user are displayed. 
   The CPU  2  then sets a page counter M to an initial value “1” (step D 4 ), sets a frame counter N to an initial value “1” (step D 5 ), reads out from the book data storage area  7   d  book data including character No., balloon, illustration, background image, letter and sound effect data contained in a first frame on a first page, and displays a character (“Mr. Y”)  403 , a balloon  409 , an illustration, a background image  406 , and letters  408  contained in the balloon  409  (step D 6 ) based on those data, as shown in the first or right frame of  FIG. 12B . 
   The read-aloud voice producing unit  13 , the voice output unit  15  and the speaker  1 E cooperate to read out the book or letter data in the balloon  409  in the voice of the reciter N 21  allocated to the character Mr. Y based on the reciter&#39;s voice data stored in the RAM voice data storage area  7   h  (step D 7 ). For example,  FIG. 12B  illustrates that a recitation “This is the house where Edison was born.” represented by the letters  408  in the first balloon  409  is being reproduced from the earphones  28  in the voice of the reciter image N 21  allocated to “Mr. Y” or character image  403 . 
   The CPU  2  displays the color of letters being at present read aloud in the balloon  409  in the reading-aloud voice in a different color from that of the remaining letters (step D 9 ). For example,  FIG. 12B  illustrates in its first or left frame that a word “Edison”  416  contained in the letters  408  in the balloon  409  is being at present reproduced audibly from the earphones  28  and also displayed in a color different from that of the remaining letters in the balloon  409 . 
   After the voice reproduction for the balloon  409  is completed, the CPU  2  further determines whether there remain any more balloons in an N th  frame (here, first frame) (step D 10 ). If there do (YES in step D 10 ), the control returns to step D 7  to iterate steps D 7 –D 9 . 
   The read-aloud voice producing unit  13  delivers the reciter voice signal along with the sound effect signal via the voice output unit  15  to the transmitter  16 , which then sends the voice signal wirelessly to the wearable device  20  through the windows concerned. The wearable device  20  receives the voice signal in its receiver  26  and outputs it from the earphones  28  audibly (step D 8 ). 
   Therefore, the user can hear words or sentences in the book “COMIC: EDISON, THE KING OF INVENTORS (BIOGRAPHY)” being read aloud or recited in the voice of the reciter who was the selected favorite famous person, inclusive of the sound effects. 
   Then, when there remain no more balloons in the N th  frame (here, first frame) (NO in step D 10 ), the CPU  2  increments the frame counter (N+1→N in step D 11 ). 
   The CPU  2  then determines whether all the letter data contained in the page has been read aloud step D 12 ). If it has not, (NO in step D 12 ), the CPU  2  iterates processes in steps D 6 –D 11  about the (N+1) th  frame. That is, the CPU  2  displays the (N+1) th  or left frame (in  FIG. 12B ) at the center of the display picture by scrolling, and controls the voice reproducing unit so that the text (letters) contained in a balloon  410  contained in the displayed frame is read aloud, that sound effect data is reproduced, and that the portion of the text being read aloud at present in the balloon is displayed in a color different from the remaining text (letter) data. 
   The left or second frame displays “Miss X” or character image  402 , an illustration or a background image  407 , letters  411  and a balloon  410  that contains the letters. The letters  411  in the balloon  410  represent the words that “Mr. A” utters. 
   Like the first frame, the second frame indicates that a recitation “A gramophone No. 1 was also completed as a result of a series of experiments.” is being reproduced from the earphones  28  in the voice of the reciter image N 22  allocated to the image  403  of the character “Miss X”, based on the processing in step D 7 . In step D 8  the second frame indicates that voice data “Mary&#39;s lamb” or sound effect data output from the gramophone is being output from the earphones  28  in the voice of the reciter image N 22  in step D 8 . 
     FIG. 12B  shows a two-frame cartoon. The number of frames of the cartoon is not limited to two and may be either one or more than two so that the number of frames displayed on a single page may be changed depending on the size of frames used, as requested. 
   When all the texts (letter) data contained in the frames of the displayed page have been read aloud (YES in step D 12 ), the CPU  2  increments the page counter M (M+1→M in step D 13 ). If all the pages have not been read aloud (NO in step D 14 ), the CPU  2  displays a next page by scrolling and sequentially causes text (letter) data in the displayed frames to be read aloud, starting with the first frame. 
   The CPU  2  produces and displays on the display unit  4  data on a M th  page based on the book data stored in the book data storage area  7   d  of the internal RAM  7 . The CPU  2  iterates steps D 5 –D 13  to reproduce text (letters) data contained in the respective N frames contained in the M th  page in a voice corresponding to a reciter and a sound effect corresponding to effect sound data, and displays the letters in the balloon being read aloud in a color different from that of the remaining letters. In synchronism with the advance of these voices, the CPU  2  scrolls and displays the frames. 
   Then, when the CPU  2  determines that all the pages have been read aloud or reproduced (YES in step D 14 ), it terminates the reading-aloud or reproducing process. When the book data is not of the cartoon or comic type in step D 1 , but for example, of the novel or story type, the CPU  2  performs the following processes (steps D 15 –D 21 ). 
   First, the CPU  2  reads out data on a title of a book, the author&#39;s name and a table of contents from the book data storage area  7   d , and displays those data on the display unit  4  (step D 15 ). The CPU  2  then extracts a narrator image or name from the book data, and displays it step D 16  in  FIG. 13A ). 
   In more detail,  FIG. 13A  illustrates a picture in which a reciter image is to be selected when reproduction of a book of a story type starts. In  FIG. 13A , a title of a book “GONE TOGETHER WITH THE SOUND”  420  is displayed as an example. Also, an image  421  of narrator R and an image  422  of narrator S are displayed along together with a reciter images N 23  of famous person C and reciter image N 25  of famous person D allocated to the respective narrator images  421  and  422  by the user. 
   One of the narrator images is selected with the cursor  23  of the input unit  3 , at which time the selected narrator image, and the reciter image and voice data allocated to the narrator image are set in the internal RAM  7 , an initial value of the page counter n is set to initial value “1” (step D 17 ), and the book data on page “1” is displayed on the display unit  4 . 
   The CPU  2  causes the narrator image to read aloud letter data  425  contained in the book data on the page “1” in the voice of the famous person represented by the reciter image allocated to the narrator image step D 18 ). 
   For example, when the narrator image S is selected in  FIG. 13A , the CPU  2  gets voice data on the reciter image N 25  allocated to the narrator image S and sets the data in the internal RAM  7 . Then, as shown in  FIG. 13B  the CPU  2  displays on the display unit  4  text (letter) data  425  on a first page of the book, transfers this data to reading-aloud voice producing unit  13 . 
   The voice producing unit  13  reads aloud the letter data as if the narrator image S narrates the content of the book concerned in a voice represented by the voice data of the famous person represented by the reciter image N 25 . 
   At this time, the CPU  2  displays the color of the part of the text (letters)  426  being read aloud in synchronism with the reading-aloud voice of the narrator image S (actually, the voice of the reciter image N 25 ) in a color different from that of the remaining text portion. For example, when a reciting sound “left” is being output audibly from the earphones  28 , the word “left”  426  of the text is displayed on the display unit  4  in a color different from that of the other words. 
   Sound effect data not included in the letter data may be inserted into the letter data as requested. For example, as shown in  FIG. 13B  a unique sound “Ta:” produced when the “narrator image S” beats his desk with a folded fan to rearrange his tone may be output audibly from the earphones  28  during the reproduction. Alternatively, sound effect data may be included in the book data so as to be produced at a predetermined timing such that the text may be narrated along with effect sounds such as the sounds of a temple bell/the singing of insects. 
   Then, when reading aloud all the text (letter) data on the M th  page is completed (YES in step D 19 ) the CPU  2  increments the page counter M (M+1→M in step D 20 ) and determines whether all the pages have been read aloud (step D 21 ). If they have not, the CPU  2  displays a next page by scrolling and then returns the control to step D 20  to read aloud letter data on the displayed M th  page. Then, when all the pages have been read aloud (YES in step D 21 ), the CPU  2  stops reproduction to thereby terminate this process. 
   When the stop switch is turned on during reproduction of the book data, reproduction of the book data is stopped and terminated. 
   As described above, according to the inventive electronic book device  1  the displayed frames and pages are scrolled in synchronism with the advance of the reading-aloud voice, so that the user need not turn the page/feed frames intentionally. Thus, the user can enjoy reading comfortably at the electronic book device  1 . 
   The copyright holder terminal  30 B is connected via the network  40  to the host server  30 . The copyright holder terminal  30 B stores in its work data RAM  30  BR work data that includes the images of reciters who, in turn, include famous persons, voice actors/actresses, etc., their names and voice data. Then, the copyright holder terminal  30 B sends the work data via the network  40  to the host server  30  (step F 20 ). Then, the host server  30  receives this work data and registers same in the RAM  31 A. Each time the host server  30  receives work data from the copyright holder terminal  30 B, the host server  30  publishes the data in the homepage thereof (step F 21 ). 
   The work data published in the homepage (HP) of the host server  30  can be utilized at a request from the electronic book device  1  (step F 1 ). A result of utilizing the work data is reported to the copyright holder terminal  30 B from the host server  30  (step F 22 ). The copyright holder terminal  30 B receives the report from the host server  30  (step F 23 ). As the electronic book device  1  downloads electronic book data, the host server  30  reports to the copyright holder terminal  30 B a result of settling a bill for the total of the price of the book data and a charge for the delivery of the book data (step F 24 ). After receiving the report the copyright holder terminal  30 B can receive a corresponding copyright fee (step F 25 ). 
   If the copyright holder terminal  30 B then newly stores in its work data RAM  30 BR work data that includes reciter images of famous actors/actresses, entertainers, Nobel prize winners and famous sportsmen and sportswomen, their names, and voice data representing their voices, the copyright holder terminal  30 B sends the work data as updated one to the host server  30  via the network  40  (step F 26 ). The host server  30  receives and stores this data in the RAM  31 A and sends this data at a request of the book device(step F 16 ). 
   As described above, each time the host server  30  receives the updated work data from the copyright holder terminal  30 B, the host server  30  publishes the data in the homepage thereof(step F 21 ). Thus, the electronic book device  1  can store the images and voice data of the reciters as the updated work data in the internal and external RAMS  7  and  8  thereof. Therefore, the electronic book device  1  can rapidly and easily utilize the data as new reciter images and their voice data to be allocated to characters appearing in the book data delivered by the host server  30  (steps F 1 –F 17 ). 
   As described above, in the book process desired book data and voice data can be read out from the external RAM  8  to thereby be read aloud in a voice represented by the voice data. A plurality of book data and voice data downloaded externally is stored in the internal RAM  7 . 
   If there arrives a telephone call during reading aloud of the book data, the CPU  2  outputs a command to report the arrival of the telephone call and a command to stop reading aloud the book data to thereby cause the corresponding process to be performed. The CPU  2  stores in the read stop register  7   i  a position on the page where the reading-aloud of the book data has stopped. When the telephone call ends, the CPU  2  reopens reading-aloud the book data at the stored position where the reading-aloud of the book data stopped. 
   The CPU  2  then determines the type of book data and changes the unit of display. For example, if the book data is of the cartoon or conic type, it can be displayed in frames, for example, in units of two frames in each of which the reciter image allocated to the character in the book reads aloud the text (letter data) in his or her voice. The CPU  2  can also change the manner of setting the kind of reading-aloud voice depending on the determined book data type. If the book data is of another type, it can be displayed in units of a page and the reciter image specified by the user reads aloud the book data in his or her voice. During reading-aloud of the book data, the frames and page under display scroll in synchronism with the advance of the reading-aloud voice. 
   As described above, the electronic book device  1  can easily download and acquire desired book data and related voice data externally. Therefore, the user can visually enjoy reading the displayed book data in silence as well as hearing the book data being read aloud in a voice corresponding to the voice data. 
   When there is an arrival of a telephone call during reading-aloud of book data, this fact is reported and the reading-aloud of the book data is automatically stopped. Thus, the user can rapidly respond to the telephone call. The position where the reading-aloud of the book data stopped at the arrival of the telephone call is stored and when the telephone call ends the reproduction of the book data reopens automatically at the position where the telephone call stopped. Thus, no manual operations are required to reopen the book reading, conveniently. 
   When the book data is of the cartoon or comic type, the images of characters appearing in the book, sentences (letter data uttered by the images, and balloons that contain the letter data are displayed in units of a frame, the letter data in the displayed balloon is read aloud in the voices of the reciter images allocated to the characters. When reading-aloud the letter data in the balloon ends, the control passes automatically to a step to process another frame in a scrolling manner. Thus, it is unnecessary to turn the page/feed the frame, and the operation is simplified. 
   Since the book content represented by the book data is read aloud in the voices of the reciter images allocated to the book characters, one character can be discriminated from another and the user can enjoy reading the book without resorting to his or her eyesight. 
   Since the present letter data being read aloud is displayed so as to be distinguishable in color from other letter data, the data can be easily confirmed. For example, even when the displayed image and letters are alternately viewed, the present book data being read aloud at that time can be easily recognized when the user shifts his or her eyesight from the image to the letters to thereby provide comfortable reading. 
   In a book of a novel or story type, the letter data to be read aloud is displayed in units of a page, and read aloud in the voice of a reciter image specified by the user. When reading aloud the letter data is completed, a next page appears (is displayed by scrolling). Thus, it is unnecessary to turn the page, and the manual operations to be performed in the reading are simplified. The voices of reciter images can be specified by selecting the reciter images to be allocated to the characters appearing in the book and can also be heard. The user therefore can enjoy reading comfortably. 
   The present invention is not limited to the contents of the above embodiment and is modifiable without departing from the spirit and scope of the present invention. For example, a voice recognizer  2 A may be provided that performs an analysis process including shortening a voice spectrum of a voice signal input by the voice input unit  14 , causing a pattern of the voice signal to match with a reference pattern to recognize the voice, and then outputting a result of the voice recognition. For example, it may be arranged that when a callee&#39;s telephone terminal No. is to be dialed, his or her telephone number data and name stored in corresponding relationship in the internal RAM  7  are instead inputted in voice into the microphone  1 C, and that the voice recognizer  2 A specifies the callee in its voice recognition process and also specifies in voice the book data to be read aloud. 
   While in the embodiment book data is illustrated as being read aloud, for example, an electronic mail received externally via the communication I/F  9  may be read aloud in the voice of the reciter image delivered by the server  30 . 
   In this case, if the CPU  2  receives the electronic mail (letter data) via the communication I/F  9 , stores it in the mail data storage area  7   e  of the internal RAM  7 , and causes a reciter image to read aloud the electronic mail, stored in the mail data storage area  7   e  by manipulating the input unit  3 , in the reciter&#39;s voice represented by the voice data delivered by the server  30 , the user can listen to the electronic book device  1  read the externally received electronic mail aloud. 
   In this case, the server  30  may prestore in the character image ROM  32 B a plurality of different action images of each of the reciter images N 21 –N 25  corresponding to letter data (words, a speech or a sentence of greeting) of a respective one of a plurality of electronic mails. The book device  1  can receive and store the plurality of different action images of each of the reciter images N 21 –N 25  from the server  30 . The book device  1  can then read and display sequentially on the display unit  4  the plurality of different actions of the reciter image in accordance with the letter data (text of the electronic mail stored in the mail data storage area  7   e  being read aloud in the voice of the reciter. For example, when the letter data of the electronic mail includes a sentence of greeting “Good morning”, the reciter image N 21  can be displayed so as to gesture “Good morning” while saying so. 
   A touch panel may be provided on each of the two display panels  1 A and  1 B of electronic book device  1  such that when one of the touch panels is depressed at any particular position, detailed data related to the depressed position is displayed on the other touch panel. For example, contents representing chapters of a book maybe provided so as to be displayed on one of the display panels. When a desired title of the contents is pressed, book data of a chapter indicated by the title may be displayed on the other display panel. In this case, turning the page in the electronic book device  1  is simplified to thereby enjoy more comfortable reading. 
   The wearable device  20  may include a headphone type book data reproducer with ear pads that include a receiving section which receives a memory card (external memory), and a voice producing unit  13  and a voice output unit  15  that cooperate to reproduce a voice that reads book data aloud. A plurality of desired book data can be downloaded from the host server  30  of the book data delivery center HS via the communication I/F  9  and stored on the memory card. Book data selected by the user can be read aloud in a voice corresponding to the selected voice data. 
   Also, when there arrives a telephone call during reading aloud of the book data in such headphone type book data reproducer, the CPU  2  generates a telephone-call arrival reporting command and a reproduction stop command to thereby cause the reproducer  20  to report the arrival of the telephone call, and to stop reading the book data aloud and display of the book data on the display unit  4  of the book device  50 . At this time, the CPU  2  stores the position where the reproduction stopped in the incoming-call register  7   i  of the internal RAM  7 . When the telephone call end, reading aloud the book data reopens at the position where the reading aloud of the book data stopped. 
   Thus, even the headphone type book data reproducer can download desired book data externally and store it on the memory card. The user can enjoy listening to the book being read aloud. When there is an arrival of a telephone call during reproduction of the book data, the telephone call is reported and reading the book aloud is automatically stopped. Thus, the user can rapidly respond to the telephone call. The position on a page where reading of the book data was stopped is stored when there is a telephone call and reproduction of the book data automatically reopens at that position when the telephone call ends. Thus, no manual operations are required when the reading reopens. 
   Provision of the timepiece  12  on the headphone type book data reproducer  60  and/or provision of the voice input unit  14  and rotary switch  11  on the electronic book device  50  are possible without departing from the scope of the present invention. 
   According to this embodiment, when delivery of book data and the images of reciters who are, for example, favorite famous persons, voice actors/actresses, animation characters, etc., is requested via the communication means by an external electronic book device, the host server can read out the book data, reciter images and corresponding voice data satisfying the request from among the plurality of such data stored in the storage means and send the data via the communication means to the external electronic book device. Thus, this process can be performed rapidly and easily. Thus, the user can anywhere acquire reciter images that read book data aloud and corresponding voice data, and reproduce the book data in the voices of the reciter images. The voices of the reciter images may additionally include those of animation characters. 
   According to this embodiment, when an external terminal (for example, a copyright holder terminal that has stored work data such as reciter images that read the content of an electronic book aloud, and corresponding voice data) sends those data via the network to the host server, the host server stores the received reciter images and voice data in corresponding relationship. When the host server is requested to deliver reciter images via the network from an external electronic book device, the host server reads out the requested reciter images and corresponding voice data and then sends those data to the external book device. Thus, the host server can rapidly and securely perform this process. 
   According to this embodiment, in the electronic book device connected via a network to the external book device delivery source the electronic book device can receive via the network from the external book device delivery source a plurality of book titles and a plurality of reciter images that read aloud the respective contents of books having those titles, and select a desired book title from among the received plurality of book titles and desired ones from the plurality of reciter images. The book device can further receive from the book data delivery source the book data specified by the desired book title, the specified reciter images and the corresponding voice data, and displays those data. The electronic book device can reproduce the contents of the book represented by the displayed book data in the voices of the displayed reciter images represented by the voice data. The reciter images include the images of famous persons, voice actors/actresses, etc. Thus, while the user is watching the delivered book data and the desired character images, the user can listen to the desired reciter images reading aloud the delivered book data in their peculiar comfortable voices.
