Description

The present disclosure relates to a broadcast audio transmitting device, a broadcast audio transmitting method, a broadcast audio transmitting program, an audio transmitting terminal, and a receiving terminal.

There is a technology that converts weather comments broadcast from broadcasting stations into audio and transmits it. When converting weather comments broadcast from broadcast stations into audio, the intonation (dialect) is required to match the local station. This is because viewers in rural areas where weather comments are broadcast will feel uncomfortable and have difficulty listening to the broadcast if there is an intonation that they are not used to hearing.

Normally, weather comments are converted into audio as follows.
First, the text of the weather comment is prepared as text data. Then, using a tool that converts text data into speech, the text of the weather comment is converted into speech with intonation that matches standard Japanese. Finally, the adjustment worker listens to the intonation of the standard language and manually adjusts the accent position to generate weather comment audio with intonation (dialect) appropriate for the local station.

At this time, there is a possibility that the adjustment operator's subjectivity will be involved, resulting in incorrect intonation. Furthermore, if the adjustment worker does not know the intonation of the local area, it takes time and effort to ask the broadcast station announcer for a voice sample and listen to it while adjusting the accent position.

Patent Document 1 discloses a technique for extracting a place name from a text of a weather comment and synthesizing the accent of the place name part.

Japanese Patent Application Publication No. 8-160983

Like many place names across the country, some place names have the same pronunciation but have different intonations depending on the region. Furthermore, there are place names that are the same as words that indicate a region, direction, or direction, such as southern, central, western, upper, lower, or southeast, and even if the words are pronounced the same, the intonation may differ depending on the region.
The technique disclosed in Patent Document 1 simply converts the place name in the text of the weather comment. Therefore, there is a problem that it is not possible to correct many place names throughout the country, or place names that are the same as a word indicating a region, direction, or direction, into an appropriate intonation according to the region where weather comments are broadcast.

In the present disclosure, when transmitting the audio of weather comments, the objective is to automatically convert the audio of the weather comments into intonation appropriate for the region where the weather is being broadcast, thereby providing easy-to-listen audio that causes less discomfort to viewers. do.

***Operation explanation***
Next, the operation of the broadcasting audio transmission device 100 according to this embodiment will be explained. The operating procedure of the broadcast audio transmission device 100 corresponds to a broadcast audio transmission method. Further, a program that realizes the operation of the broadcast audio transmission device 100 corresponds to a broadcast audio transmission program.

FIG. 2 is a flow diagram showing an example of the operation of the broadcasting audio transmission device 100 according to the present embodiment.
In this embodiment, the broadcast audio transmitting device 100 transmits weather comment audio 68 that is broadcast about the weather in a specific broadcast area.

<Data reception processing>
In step S101, the data receiving unit 110 receives raw weather data 61 from a weather company or the like. Specifically, the data receiving unit 110 receives weather data 61 in XML format from a weather company or the like. XML is an abbreviation for Extensible Markup Language.
Note that the weather data 61 is an example of broadcast data that is the source data of broadcast comments broadcast in a specific broadcast area.

FIG. 3 is a diagram showing a configuration example of weather data 61 according to the present embodiment.
The weather data 61 is transmitted from a weather company or the like as data for each prefecture. Since the weather data 61 is transmitted as data for each prefecture, the data receiving unit 110 can recognize and receive the weather data 61 that includes a specific broadcast area in which weather comments are broadcast.

The weather data 61 is transmitted from a weather company or the like for each data type. The data type represents the type of weather data 61. The types of weather data 61 include, for example, prefectural forecasts and AMeDAS information.

<Data registration process>
In step S102, the data registration unit 120 extracts weather data in area information included in a specific broadcast area from the weather data 61, and registers it in the weather database 62 for each data type.
Specifically, the data registration unit 120 extracts area information from the weather data 61 based on the tag of the weather data 61. The area information is a region name representing a region or a direction (including direction). The area information also includes area names that have different intonations depending on the broadcast area. Specific examples of area names will be described later.

In the example of FIG. 3, the area information is the information in the tag <Area>, and is "southern" with the code "420010". Below, area information may be simply referred to as an area.
Furthermore, the data registration unit 120 determines the data type of the weather data 61 from the tag information. In the example of FIG. 3, since the information in the tag <Title> is "prefectural weather forecast", the data type is determined to be "prefectural forecast". The correspondence between the information in the tag <Title> and the data type can be set arbitrarily.
The data registration unit 120 extracts weather data in the area information from the weather data 61 and registers it in the weather database 62 together with the data type.

<Audio data generation process>
In step S103, the audio data generation unit 130 generates audio data 63 representing the audio structure of the weather comment using weather data in area information included in a specific broadcast area. The audio data generation unit 130 acquires the data type included in the weather data of a specific broadcast area, and generates audio data 63 representing the configuration of audio according to the data type. When generating the audio data 63, the audio data generation unit 130 generates the audio data 63 by referring to the audio text template 70a.
In this embodiment, the audio data 63 includes, as area information, a region name that represents a region or a direction (direction) and has different intonations for each broadcast region. Specifically, in this embodiment, the audio data 63 includes a code that represents a region or direction (direction) and specifies a region name having different intonation for each broadcast region.

FIG. 4 is a diagram showing an example of the configuration of audio data 63 according to this embodiment.
FIG. 4 shows audio data 63 whose data type is "prefectural forecast" and audio data 63 whose data type is "AMeDAS information."
A specific explanation will be given using the weather data 61 shown in FIG. 3, the audio text template 70a shown in FIG. 13, and the audio data 63 whose data type is "prefectural forecast" shown in FIG.

The audio data 63 of the data type "Prefectural Forecast" shown in FIG. 4 represents the audio structure of the weather comment when broadcasting the "Prefectural Forecast". [Sound_FIX] is a tag indicating that it is confirmed as audio data 63, and [Sound01] is a tag that indicates that the right side of “Comment=” registered in the [Sound01] tag of the audio text template 70a is added to the audio document. This is a tag indicating that it is included as a part. The text on the right side of "Comment=" is "Today's weather in the prefecture" as shown in FIG. 13. The audio data generation unit 130 operates to input [Sound_FIX] and [Sound01] in a fixed format.
[Sound02] is a tag indicating the weather forecast, and [Sound03] is a tag indicating the probability of precipitation, and the audio data generation unit 130 extracts the corresponding data from the weather data 61. For example, if it is set in advance that <WeatherCodePart> of the weather data 61 corresponds to [Sound02] and refID="1" corresponds to "Southern part (code is 420010)", the audio data generation unit 130 , register the character string "=:201::" following "Nanbu (code is 420010)" in [Sound02].
Furthermore, if <Probability of Precipitation Part> of the weather data 61 corresponds to [Sound03] and it is set in advance that refID="1" corresponds to "Southern part (code is 420010)", the audio data generation unit 130 In [Sound03], register the character string "=::10:30" following "Nanbu (code is 420010)".
Although FIG. 3 illustrates a part of the weather data 61 and does not show all the original data for generating the audio data 63, the audio data generation unit 130 can generate the weather data by operating in this way. Audio data 63 is generated from 61.

It is assumed that "Southern" is a region name 201 that represents a region, direction, or direction, and has different intonations depending on the broadcast region.
For example, in a weather comment for "Prefectural Forecast,""in the southern part of Nagasaki Prefecture" means the southern region of Nagasaki Prefecture. The code for "southern" in the weather comment for "prefectural forecast" is 420010.
On the other hand, assume that the proper name Nanbu exists in Yamanashi Prefecture, and that the intonation is different from the standard name Nanbu. At this time, in the weather comment of "AMeDAS Information", when it says "in the southern part (town) of Yamanashi Prefecture", it means specifically "southern part (town)". The code for "southern" in the weather comment of "AMeDAS information" is 49316.
For example, if the word ``nanbu'' in ``Nagasaki Prefecture's southern part'' is broadcast with an intonation unique to Yamanashi Prefecture, it will feel strange to viewers in Nagasaki Prefecture, and the broadcast will become difficult to listen to.

Region names 201 that represent a region, direction, or direction and have different intonations depending on the broadcast region include names that represent directions such as southern, central, northern, upper, lower, upper, and lower, as well as names that represent directions such as west, north-south, and east-west. Also includes names representing directions. In addition, the area names 201, which represent a region, direction, or direction and have different intonations depending on the broadcast area, include many place names across the country such as Fukuoka, Fujimi, Hiroshima, Gojo, and Oji (Oji). In the following, the direction includes the direction.

FIG. 5 is a flowchart illustrating an example of the operation of the broadcasting audio transmitting apparatus 100 according to the present embodiment, which is a continuation of FIG. 2 .

<Audio text generation processing>
In step S104, the audio text creation unit 140 converts the tags and character strings included in the audio data 63 into sentences by using the audio text template 70a, the weather conversion table 70b, and the precipitation probability conversion table (for W1 conversion). ) 70c and precipitation probability conversion table (for W2 conversion) 70d are used. The audio text creation unit 140 refers to the audio text template 70a and sequentially converts the definition information of the audio data 63 into sentences. First, [Sound01] is converted to "Today's weather in the prefecture" with reference to the audio sentence template 70a.
Next, [Sound02] is converted. At this time, the audio text creation unit 140 uses the name conversion table 64 to convert the region name 201 included in the audio data 63 into a converted name 202. Then, the audio text creation unit 140 creates audio text 65 that includes the converted name 202 and becomes a weather comment candidate. At this time, the audio text creation unit 140 generates the audio text 65 using the name conversion table 64 according to the data type.

FIG. 6 is a diagram showing an example of the configuration of the name conversion table 64 according to this embodiment.
The name conversion table 64 includes a code for specifying a region name 201 that represents a region or direction and has different intonation for each broadcast region, and a converted name 202 in which additional data 301 representing the region or direction is added to the region name 201. This is a table for associating.
The name conversion table 64 is stored for each data type representing the type of weather data.

In the name conversion table 64, a data type 641, a code 642 indicating an area, and converted name text data 643 are set.
In the data type 641, a data type indicating the type of weather data is set. Data types include, for example, prefectural forecasts and AMeDAS information. The name conversion table 64 has an item of data type 641, as in the example of FIG. 6, and the setting items of the name conversion table may be divided for each data type. Alternatively, it may be a name conversion table that is physically separated for each data type. In that case, it is not necessary to have the data type 641 item.
In the code 642, a code indicating the area corresponding to the data type 641 is set. In FIG. 6, the area that is the area name 201 is written in parentheses after the code, such as "420010 (southern part)". However, this is written to make it easier to understand the correspondence between the data type and the converted name, and is not actually set.

In the combination of the data type 641 and the code 642, for example, when the data type 641 is a prefectural forecast and the code 642 is 420010, the text data of the converted name 202 is set in the converted name text data 643. In the example of FIG. 6, "Southern <Prefecture>" is set as the converted name 202 for "Southern" which is the area name 201 of the prefecture forecast. Furthermore, for example, when the data type 641 is AMeDAS information and the code 642 is 49316, "Southern <Yamanashi>" is set as the converted name 202 for the area name 201 "Southern".
"<Prefecture>" in "Southern <Prefecture>" and "<Yamanashi>" in "Southern <Yamanashi>" are additional data 301 representing a region or direction.

Then, the character string "=:201::" refers to the weather conversion table 70b and becomes "cloudy and sometimes sunny", and according to the definition of the audio sentence template 70a, [Sound02] becomes "southern <prefecture>". is translated into "cloudy and partly sunny".
Next, [Sound03] is converted, but by referring to the audio sentence template 70a, the precipitation probability conversion table (for W1 conversion) 70c, and the precipitation probability conversion table (for W2 conversion) 70d, [Sound03] is converted to "precipitation". The probability is 10% until noon and 30% until 6pm." At this time, referring to the precipitation probability conversion table (for W1 conversion) 70c, since W1 is 10, "10% until noon" is specified, and referring to the precipitation probability conversion table (for W2 conversion) 70d, Since W2 is 30, "30% until 6 pm" is specified.

FIG. 7 is a diagram showing an example of the audio sentence 65 according to the present embodiment.
Regarding the audio sentences 65 in the upper and lower rows of FIG. 7, the upper row is an example of the audio sentences 65 before the length of the playback time is adjusted, and the lower row is an example of the audio sentences 65 after the length of the playback time is adjusted. represents. Adjustment of the reproduction time length of the audio text 65 will be described later.

For example, the audio text creation unit 140 uses the name conversion table 64 of the data type "prefectural forecast" shown in FIG. 6 to convert the audio data 63 of the data type "prefectural forecast" shown in FIG. The upper audio sentence 65 is created.
In the audio text 65 shown in the upper row of FIG. 7, the region name 201 "Southern" included in the audio data 63 has been converted to the converted name 202 "Southern <prefecture>". Further, it is predetermined that information in parentheses "<>" is not spoken.

In step S105, the audio text creation unit 140 determines whether the playback time of the created audio text 65 is within a specified length.
Specifically, the audio text creation unit 140 totals the playback time of each audio file of all the clauses used in the audio text 65, and determines whether the total playback time is within a specified length. By doing so, it is determined whether the reproduction time of the audio sentence 65 is within the specified length.
Here, a phrase indicates a unit of an audio file. Therefore, phrases also include words.
If the reproduction time of the audio text 65 is not within the specified length, the process advances to step S106.
If the reproduction time of the audio text 65 is within the specified length, the process advances to step S107.

If the reproduction time of the audio sentence 65 is not within the specified length, in step S106, the audio sentence creation unit 140 adjusts the audio sentence 65 according to a predetermined rule.
In the example of FIG. 7, an example is shown in which the audio sentence 65 in the upper row is adjusted to the audio sentence 65 in the lower row. In the audio text 65 in the upper row, "The chance of precipitation is 10% until noon and 30% until 6:00 p.m.", and in the audio sentence 65 in the lower row, "The probability of rain is 10% until noon." ” to shorten the playback time of the audio text 65.
The predetermined rule is, for example, "Delete forecast information starting from the latest time" (part W2 in the example shown in FIG. 7), and the judgment in step S105 and the step The process of S106 is repeated.

In step S107, the audio text creation unit 140 outputs the audio text 65 whose playback time is within the specified length.

<Audio transmission processing>
When the audio sentence 65 is completed, the audio sending unit 150 uses the audio conversion table 66 to reproduce the phrases included in the audio sentence 65, thereby transmitting the weather comment audio 68.
Specifically, it is as follows.

First, in step S108, the audio sending unit 150 uses the audio conversion table 66 to determine the order of the audio files 67 according to the order of the clauses included in the audio sentence 65.

FIG. 8 is a diagram showing an example of the configuration of the voice conversion table 66 according to this embodiment.
FIG. 9 is a diagram showing an example of the configuration of the audio file 67 according to this embodiment.
In the voice conversion table 66, phrases used for weather comments are associated with the sounds of the phrases. Specifically, in the voice conversion table 66, text data of a phrase used for a weather comment is associated with audio file identification information that identifies an audio file that stores the voice of the phrase.

In the voice conversion table 66, phrase text data 661 and voice file identification information 662 of the voice file storing the voice of the phrase set in the phrase text data 661 are set.
The example of the first to third lines of the bunsetsu text data 661 corresponds to "%Pwa" of the audio sentence template 70a [Sound02] tag shown in FIG. 13. "%P" corresponds to area information and is followed by the particle "ha", so the examples are "northern wa", "southern <prefecture>wa", and "southern <Yamanashi>wa". By specifying the tag of the audio text template 70a, an audio file 67 is created in which an arbitrary particle is added after the area information.
As shown in FIG. 9, each of the audio files 67 is configured to be searchable using audio file identification information 662.

In the voice conversion table 66, phrases used for weather comments are set as phrase text data 661.
If the phrase is a region name 201 having different intonations depending on the broadcast region, the converted name 202 is set in the phrase text data 661. Therefore, as shown in FIG. 8, "Nanbu <prefecture>" and "Nanbu <Yamanashi>" are set in the bunsetsu text data 661 as converted names 202 corresponding to the region name 201 "Nanbu".
Each post-conversion name 202 is associated with an audio file in which audio with an intonation corresponding to the additional data is stored.

In this way, in the voice conversion table 66, a phrase is associated with an audio file in which the voice of the phrase is stored, and the converted name 202, which is a phrase, stores the voice of the intonation according to the additional data. The audio file that was created is associated with the audio file.
For example, as the voice of the converted name 202, a voice with an appropriate intonation is stored by storing a voice obtained in advance from a local announcer.

In step S109, the audio transmitter 150 transmits the weather comment audio 68 by reproducing the audio files 67 in the determined order.

FIG. 10 is a diagram showing an example of the order of the audio files 67 determined by the audio sending unit 150 according to the present embodiment.
As shown in FIG. 10, by reproducing the audio files 67 in the determined order of the audio files 67, the weather comment audio 68 is transmitted.
