The FM character multiplexed signal received by the tuner 1 is demodulated by an FM multiplex demodulator 12 and subjected to a predetermined error correction process before being supplied to a second controller 13. The second control unit 13 composed of a microcomputer includes:
Normal packet data is extracted from the input multiplexed data, and a process described later is executed. While one page is not completed, the packet data is registered in the irregular data RAM 14a of the first RAM 14 and is completed. The completed data for one page is sequentially registered in the regular data RAM 14b of the RAM 14.

The page data registered in the regular data RAM 14b refers to the character ROM 15 that converts kanji and symbols in accordance with the page display output instruction of the key group 9, and reconstructs the data as characters and symbols on the display 16
To be displayed.

The third control unit 17 as a processing means for performing speech synthesis is constituted by a microcomputer. In the third control unit 17, the operation of the first and second control units 8 and 13 causes
The page data registered in the regular data RAM 14b is
Digital speech data is output as page data reconstructed with reference to the speech synthesis dictionary 18. The digital audio data output from the third control unit 17 is D / A
The analog signal is converted by the converter 19 and supplied to the output side of the first mute unit 3, that is, the input side of the selector 4 via the second mute unit 20. Specifically, when the audio output of the character information is selected from the key group 9, the muting of the broadcast audio in the first mute unit 3 is turned on, and the muting in the second mute unit 20 is turned off. A reading service of character information by voice can be received from the speaker 7 via the selector 4.

The above-mentioned speech synthesis dictionary 18 is composed of a regional speech synthesis dictionary 18a and a standard speech synthesis dictionary 18b. In the area-based speech synthesis dictionary 18a, speech reading data in a special reading manner is written for specific place name characters that are read differently for each use area in accordance with the use area. To be more specific, if the area of use is limited to Japan, the regional speech synthesis dictionary 18a is provided with a storage area for each prefecture, and as shown in FIG. "Storage area 1" corresponding to "Tokyo"
, The speech synthesis data of the reading method is written corresponding to the character code of the special reading method in “Tokyo”. Here, the special reading character code is written as "Fussa". Speech synthesis data for reading is written in "Husa" in katakana.

In addition, in this example, the speech synthesis dictionary 1 for each region is used.
In the “storage area 2” corresponding to “Aichi” in the use area of 8a, “Sakaecho”, a character code of a special reading character in “Aichi”, and “Sakaecho” of speech synthesis data of the reading method are included. Has been written. Special readings of the area of use and voice synthesis data thereof are similarly written in the other storage areas corresponding to each prefecture.

FIG. 3 shows the layout of the front panel of the FM teletext receiver according to the present invention. The key group 9 connected to the first control unit 8 is used when instructing to change the setting of the use area. , A "voice" key 9b operated when instructing on / off of the reading service, and a "region" key 9a, which are operated next to operate the up / down operation area. It is composed of an "up" key 9c and a "down" key 9d for changing the direction, a "decision" key 9e for operating the "up" key 9c and the "down" key 9d to determine the use area being switched. I have.

Next, the operation when the character "Gujo Hachiman" is received with the use area set to "Gifu" will be described with reference to the flowchart shown in FIG.

In step S1, the regular data RAM 14
Assuming that data is registered in b, a voice synthesis command and designation of a use area are performed. In step S2, the completed page data is read from the regular data RAM 14b, and in step S3, the use area set in the first control unit 8 or the second control unit 13 is read. Here we read that it is "Gifu".

In the next step S4, the "storage area 3" corresponding to "Gifu" of the use area of the speech synthesis dictionary 18a for each area is used.
Is searched using the character code of "Gujo Hachiman" as a key. In step S5, it is determined whether the search result in step S4 has been hit. Here, it is determined that a hit has occurred since the reading voice synthesis data is set in the “storage area 3” corresponding to the character code of “Gujo Hachiman”.

In step S6, the data is registered in the corresponding portion of the reading area of the second RAM 21. In step S7, it is determined whether or not there is an empty block in which the speech synthesis code has not been determined in the reading area of the second RAM 21, that is, 1
It is determined whether data for the page is completed.

If it is determined in step S5 that there is no hit, in step S8 a search is performed using the character code received from the standard speech synthesis dictionary 18b as a key, and the search result is determined in step S6 as the corresponding read-out area of the second RAM 21. Register in the location.

When it is determined in step S7 that the speech synthesis data of one page of data has been completely completed in the reading area of the second RAM 21, the process proceeds to step S9, where the reading area of the reading area of the second RAM 21 is read. The speech synthesis data is output to the D / A converter 19 and read. In this case, the traffic information containing the characters “Gujo Hachiman”, specifically, the reconstructed character data for one page of “Now, 4 km north from Gujo Hachiman” is correct. "Gujo Hachiman" is read as "Gujo Hachiman".

When the area of use is changed to Osaka,
Operate the "Area" key 9a to increase the use area /
By operating the key 9c or the key 9d for changing in the down direction, the character "Osaka" is displayed on the display window 22 of the display device 16. When the "OK" key 9e is operated in the state where the character "Osaka" is displayed on the display window 22, the use area is determined to be "Osaka".

If the traffic information for one page of "Currently 4 km north from Yawata in congestion" with the word "Yawata" is reconstructed during use in Osaka, "Yawata" It is read as "Yawata" of correct reading instead of "Hachiman".

As described above, when the character data received by searching the area-based speech synthesis dictionary according to the set use area is registered, the speech synthesis of a special reading method according to the use area is registered. Since character data received by allocating data is read aloud, special characters are also read aloud in a correct manner in the region of use, and the usability is good.

[Embodiment 2] In [Embodiment 1], an area to be searched is specified and processed using a use area as a search key. In [Embodiment 2], a specific place name character is used as a search key. The area to be searched is specified and processed.

FIG. 5 shows a speech synthesis dictionary 18 for each region in this case.
The content of “a” is shown, and the voice synthesis data of the reading method for each use area is written in correspondence with the character code of the special reading method for each storage area. Specifically, "storage area 2" corresponds to the special reading character code "Yawata", and the reading area is "Yawata" when the use area is "Osaka" and the reading method is "Fukuoka" when the use area is "Fukuoka". Is written as "Yahata".

In the following, similarly, the speech synthesis data of the reading method for each use area is written in the regional speech synthesis dictionary 18a corresponding to the character code of the special reading method for each prefecture.

Also in the case of [Embodiment 2], in accordance with the flow shown in FIG. 4 described in [Embodiment 1], the local speech synthesis dictionary is used preferentially over the standard speech synthesis dictionary, and the setting is performed. The received character data can be read aloud by allocating speech synthesis data of a special reading method according to the used area.

[Embodiment 3] [Embodiment 1] In [Embodiment 2], in addition to the standard speech synthesis dictionary in which speech synthesis data of the standard reading of each character is written, the reading method is different for each use area. Prepared a regional speech synthesis dictionary in which speech data with a special reading method was written to correspond to the area of use for specific place name characters that differed, and used the regional speech synthesis dictionary in preference to the standard speech synthesis dictionary. And a speech synthesis dictionary for each use area in which the first speech synthesis data of the specific place name character and the second speech synthesis data of the standard reading which are different for each use area are written, and set in the area designating means. Processing means for retrieving a speech synthesis dictionary corresponding to the area of use, assigning the first speech synthesis data to the received character code prior to the second speech synthesis data, and reading out the speech. A text multiplex broadcast receiver is prepared, a voice synthesis dictionary corresponding to the set use area is searched, and the first voice synthesized data is assigned to the received text data with priority over the second voice synthesized data. Also, by reading the text data, the received character data can be read aloud by allocating speech synthesis data in a special reading method according to the set use area.

However, in the case of [Embodiment 3], each of the speech synthesis dictionaries for each use area includes the standard speech synthesis dictionary 1 found in [Embodiment 1] and [Embodiment 2].
Since the data of 8b is written, as the number of use areas that can be switched increases, wasteful memory capacity consumption becomes a problem.
