Description

  The present invention relates to a program sound production apparatus and a program sound production program for producing sound used for a program.

In recent years, synthesized speech based on speech synthesis technology using a computer has been used as an automatic announcement in trains, station platforms, and the like.
For example, this synthesized speech is synthesized from computer generated speech so that prosody and intonation are not heard unnaturally.

  In general, synthesized speech consists of computer-generated speech, that is, speech that is generated by a machine and speech that is actually uttered by a person. There is a voice connected according to data (for example, see Patent Document 1).

By the way, in the weather forecast program broadcast late at night or early in the morning, normal still images showing the weather forecast for each region, temperature, probability of precipitation, and the presence of various weather warnings (broadcast screens and On the screen, for example, in the case of a weather forecast program, only a video on a map or the like in which a mark indicating sunny or cloudy is arranged for each region is repeatedly broadcast. Such a weather forecast program is formed by replacing normal still images in order every few seconds or several tens of seconds without sound of announcement and without sound.
JP 2000-181476 A

  However, the synthesized speech (sound by the machine) by the speech synthesis technology does not satisfy the level that can be used in broadcasting, that is, whether the sound quality is good or it can be heard naturally. There is a problem that it takes time and effort to correct the processing.

  Synthetic speech (synthesized speech) by speech synthesis technology is a combination of speech uttered by humans, so the sound quality is not inferior, but the connection between words is likely to be unnatural. There is a problem that the interval is worsened. Even if the interval between words is successfully obtained, if the synthesized speech is used for a program, synthesized speech that reads different contents every day is set in advance. There is a problem that it is difficult to fit within the broadcast time of the program.

  For example, the sound used in a weather forecast program is different in the local name and the part that describes the weather, but the same fixed sentence is repeated, and the part is well connected by using the voice actually read out by the announcer etc. If it is changed, the sound of the program with good sound quality can be created, but there is no one that can adjust the time by changing well so that it is within the broadcast time of the program.

  Furthermore, when using synthesized speech by speech synthesis technology as program audio, these timings are simplified so that the normal still image display timing and the synthesized speech output timing do not become unnatural. A tool (apparatus, program, etc.) that can match the above is desired.

  By the way, as a practical problem, although it is an economic reason, it is difficult to arrange an announcer for a program such as a weather forecast program that is broadcast late at night or early in the morning due to the production budget. There is a demand for a synthesized voice that has good sound quality and can be heard naturally without being put on.

  That is, it has been desired to automatically create the sound of a program that satisfies the standard that can be used in broadcasting without actually arranging an announcer. That is, there has been a demand for a voice that is uttered by a person who has performed speech training such as an announcer, and that can create a voice of a program that can be used for a program without taking time and effort for modification.

Here, as an example of the accumulated data window, a state where the weather data window is opened is shown. The weather data window displays and edits the variable processed by each control icon. The variable displayed in the weather data window is a message that is a result of analyzing the code data received by the code data receiving means 13. It is stored in the analysis result. The code data is obtained from a weather-related data server managed by the Japan Meteorological Agency or the like.

  Also, the tag “○ △ telegram” displayed in this weather data window shows the telegram analysis result of the warning / warning, and “□ × telegram” shows the other telegram analysis result.・ ・ ”Telegram” shows the telegram analysis result of the weather forecast.

  The general variable window is a place where general variables processed by each control icon are displayed and edited. General-purpose variables displayed in the general-purpose variable window are preset, and include character string variables and integer variables. The character string variable is a variable for setting a character string operable in the item scenario file, and the integer variable is a variable for setting an integer operable in the item scenario file.

  Returning to FIG. The script file setting means 9 sets a script file formed by arranging the order of the item scenario files in accordance with the script file operation signal output from the operation means 3, and includes an expansion / contraction degree setting means 9a. . The set script file is output from the script file setting means 9 to the display means 23 and displayed.

  The script file defines, for each program, the flow of the program, that is, the order of sending the item files, and the program sending time, which is the time for sending all items (the time for sending the entire program).

  In addition, this script file includes the previous silent time from the start time of the item until the actual sound is output, and the actual sound output (audio playback time) within the item after the end of the actual sound output. The silent time after the silent time until the end time of the item is set. For example, for an item with a basic transmission time of 20 seconds, the pre-silence time can be set to 500 ms and the post-silence time can be set to 2000 ms.

  The expansion / contraction degree setting means 9a constitutes the program when the total actual transmission time (total time) of items set in the item scenario file does not match the program transmission time for transmitting the entire program. The degree of expansion / contraction (elongation level, contraction level) to be referred to when adjusting the sending time of the item is set. The degree of expansion / contraction refers to the ease with which the basic transmission time of an item can be reduced, the degree to which it can be extended, that is, how much the item can be shortened or extended from the actual transmission time. . In this embodiment, the degree of stretching is given by “shrinkage” (easy to shrink) and “elongation” (easy to stretch), and is given by an integer of 1 to 10 (level of 1 to 10). Larger integers are easier to shrink or stretch, and smaller integers are less likely to shrink or stretch.

  The ease of shrinking the basic sending time of an item (“shrinkage”) indicates a measure of how much the item can be shortened from the actual sending time of the item. For example, as a simple example, the sending time of the item is 10 In the case of the second, in “Shrinkage 1”, the transmission time after adjustment of the item can be shortened to 8 seconds, and in “Shrinkage 2”, the transmission time after adjustment of the item is shortened to 6 seconds. be able to.

  As a complicated example, for a program consisting of item A, item B, and item C, the basic transmission time of item A is 10 seconds and “shrinkage 3”, and the basic transmission time of item B is 30 seconds and “shrinkage”. 2 ”, the basic transmission time of item C is 20 seconds,“ shrinkage 6 ”, and the program transmission time is 60 seconds, the transmission time of item A is 20 seconds, and the transmission time of the item is 25 seconds. Suppose that the transmission time of item C is 30 seconds. Then, since the total time that is the sum of the transmission times of item A, item B, and item C is 75 seconds, the difference from the program transmission time of 60 seconds, that is, the total reduction time that must be shortened ( Total shortening time) is 15 seconds.

  Since the items whose sending time is longer than the basic sending time are item A and item C, the shortening time of item A is based on “shrinkage 3” of item A and “shrinkage 6” of item C. 15 seconds x 3 / (3 + 6) is 5 seconds, Item C shortened time is 15 seconds x 6 / (3 + 6) 10 seconds, Item A adjustment sending time is 20 seconds-5 seconds 15 seconds, The transmission time after adjustment of item B is 25 seconds as it is, and the transmission time after adjustment of item C is 20 seconds from 30 seconds to 10 seconds.

  The ease of extension of the basic delivery time of an item (“elongation”) indicates a measure of how much the item can be extended from the actual delivery time of the item. For example, as a simple example, the delivery time of the item is 10 In the case of “second”, “elongation 1” can extend the transmission time after adjustment of the item to 12 seconds, and “elongation 2” extends the transmission time after adjustment of the item to 14 seconds. be able to.

  As a complicated example, for a program consisting of item i, item b, and item c, the basic transmission time of item i is 30 seconds and “elongation 4”, and the basic transmission time of item b is 20 seconds and “elongation”. 5 ”, the basic transmission time for item C is 3 seconds,“ elongation 2 ”, and the program transmission time is 60 seconds, the transmission time for item A is 20 seconds, and the transmission time for item B is 17 seconds. It is assumed that the transmission time of item C is 5 seconds. Then, since the total time that is the sum of the transmission times of item A, item B, and item C is 42 seconds, the difference from the program transmission time of 60 seconds, that is, the total extension time that must be extended ( Total stretching time) is 18 seconds.

  The items whose sending time is shorter than the basic sending time are item i and item b, so the extension time of item i is based on “elongation 4” of item i and “elongation 5” of item b. 18 seconds x 4 / (4 + 5) is 8 seconds, item b stretching time is 18 seconds x 5 / (4 + 5) 10 seconds, item a after adjustment is 20 seconds + 8 seconds 28 seconds, item The transmission time after adjustment of B is 17 seconds + 10 seconds, which is 27 seconds, and the transmission time after adjustment of item C is 5 seconds as it is.

  For each item, a lower limit time that is the limit time (minimum time) that can shorten the sending time and an upper limit time that is the limit time (maximum time) that can lengthen the sending time are set by the item scenario file. ing.

  That is, the degree of expansion / contraction determines the amount of time that can be added in an item set in the item scenario file, or the amount of time that can be deleted in an item set in the item scenario file.

  The script file storage means 11 is composed of a general recording medium such as a hard disk or a non-volatile memory, and stores the script file set by the script file setting means 9.

  Here, the display screen on which the script file set by the script file setting means 9 is displayed on the display means 23 will be described with reference to FIG. FIG. 3 shows a script (script editor) in which a script scenario of the weather forecast program is developed on the display means 23 when the program for producing the sound is a weather forecast program.

  As shown in FIG. 3, the weather forecast program edited by the script editor has a program script name (file name) of “script for weekdays 2150” and a program transmission time of 120 seconds, that is, 2 minutes from 21:50 on weekdays. "Night Opening Title", "Warning / Warning", "Current Temperature", "Tomorrow Weather", "Tomorrow Temperature and Wave", "Weekly Weather", "Ending" and "End" It consists of an item scenario file with the item name “”.

  The item scenario file will be described. In the “night opening title”, the basic transmission time of the item is 10 seconds, and the contraction “5” and the expansion “5” are set. In the “alarm / caution”, the basic sending time of the item is 20 seconds, and the contraction “1” and the extension “10” are set. In the “current temperature”, the basic sending time of the item is 7 seconds, and the contraction “4” and the extension “5” are set. In “Tomorrow's weather”, the basic transmission time of the item is 33 seconds, and the contraction “4” and the expansion “5” are set. In “Tomorrow's temperature and wave”, the basic sending time of the item is 25 seconds, and the contraction “3” and the extension “5” are set. In “weekly weather”, the basic transmission time of the item is 15 seconds, and the contraction “3” and the expansion “5” are set. In “ENDING”, the basic sending time of the item is 10 seconds, and the contraction “5” and the extension “5” are set. In “END”, a program transmission time of 2′00 ″ (120 seconds) is set.

  For example, in the weather forecast program “weekday 2150 script” shown here, the basic transmission time of the main item “Tomorrow's weather” of the program is 33 seconds, which is the longest time. The basic transmission time of “alarm / warning” is as short as 20 seconds. However, the growth rate of the item “Tomorrow's weather” is “5”, whereas the growth rate of the item “Warning and warning” is “10”. This is because the item “Tomorrow's weather” is composed of text audio data of a certain amount depending on the day, whereas the item “alarm / warning” can be text audio data of a different amount depending on the day. is there. In other words, the item “Warning / Warning” includes, for example, when a typhoon is approaching, when there is a possibility of a tsunami due to an earthquake, or when a landslide may occur due to a long rain. This is because the content may increase.

  In each item scenario file, even if the basic transmission time of each item is shortened or extended based on shrinkage or expansion, the total of the actual transmission times of the items constituting the program does not match the program transmission time. In any case, for any item, a switching priority ("switching" in FIG. 3) indicating a priority for switching to another candidate set in this item can be set. In this embodiment, as the switching priority is larger, when the total transmission time of items constituting the program does not match the program transmission time, the switching priority is preferentially switched to another candidate in the item. It is done. Here, it is configured such that an item with a higher switching priority value is preferentially switched to another candidate within the item, but conversely, an item with a lower switching priority value is preferentially You may comprise so that it can switch to another candidate within an item.

  In this script editor, each item scenario file can be inserted and deleted with the “Insert” and “Delete” buttons, and the transmission order of each item scenario file can be changed with “Sending Order ↑”, “Sending” There are buttons for “order ↓”, “copy script” and “print script” for copying and printing a script file.

  The script editor is provided with a portion for displaying the properties of the selected item scenario file. Here, the properties of the item scenario file of “alarm / warning” are displayed.

  The properties of this item scenario file include item name “alarm / warning”, scenario file “kech.xsn”, basic transmission time “20 seconds”, upper limit time “30 seconds”, and lower limit time “18 seconds”. ”, Front silence time“ 500 ms ”, rear silence time“ 2000 ms ”, ease of contraction“ 1 ”, ease of extension“ 10 ”, omissible check column, omission priority“ 8 ”, Candidate switching priority “10” can be set. Further, “multiple still image type” is set as an item type indicating what kind of image is displayed as a program when the item is transmitted. Note that the multiple still image type indicates a format in which a plurality of still images are switched at every elapse of a predetermined time while the item is being transmitted.

  Returning to FIG. The code data receiving unit 13 receives code data via a network (Internet, intranet, etc.). The code data is set at the transmission source. The transmission source is, for example, the Japan Meteorological Agency, a traffic information center, a road public corporation or the like, and a server or the like managed by these is applicable. Data corresponding to the code data is defined in an item defined in the item scenario file.

  The program sound production apparatus 1 defines the relationship between the code data and the fixed sentence used for the sentence sound data and the part sound file in the item scenario file set by the item scenario file setting means 5. The program audio production means 17 connects the component audio files based on the code data. For example, in the item scenario file, code data “001” is defined as a fixed phrase “Tomorrow's weather is OO”, and code data “002” is “Tomorrow's weather is △△.” It is defined as a fixed phrase.

  The code data storage means 15 is constituted by a general recording medium such as a hard disk or a nonvolatile memory, and stores the code data received by the code data reception means 13.

  The program sound production means 17 is based on the item scenario file set by the item scenario file setting means 5, the script file set by the script file setting means 9, and the code data output from the code data receiving means 13. , Which produces the audio of a program, is provided with item production means 17a, item synthesis means 17b, and program time adjustment means 17c.

  The item production means 17a produces items by referring to the code data based on the item scenario file set by the item scenario file setting means 5 and searching for and connecting the component audio files. File search means 171 is provided.

  The component audio file search means 171 omits the illustration of the component audio file which is each part of the sentence in order to produce the sentence (sentence audio data) included in the item set in the item scenario file. The search is performed from the broadcast audio dictionary output from the component audio extraction device.

  That is, in order to produce the text (sentence voice data) included in the item scenario file, the item creation means 17a first searches the part voice file from the broadcast voice dictionary for each sentence. By connecting (connecting) the component audio files, each sentence (sentence audio data) is produced, and these are listed in the order set in the item scenario file.

  Note that the sentence sound data (Wave file) produced by the item producing means 17a is originally composed of a part sound file in which sound and text are managed integrally (a pair). The data and the text data in which the extension of the file name attached to the sentence audio data is txt can hold a one-to-one relationship. Therefore, it can be said that by displaying the text data on the display means 23, the output sound (sentence voice data) can be visually confirmed.

  The item synthesizing unit 17b synthesizes the items produced by the item producing unit 17a based on the script file set by the script file setting unit 9, and produces the audio of the program. In other words, the item composition unit 17b rearranges (aligns) the produced items in the transmission order set in the script file.

  The program time adjusting unit 17c adds up the actual transmission time for each item combined by the item combining unit 17b, and compares the total time (total time) with the program transmission time which is the time for transmitting the entire program. The program time determining means 172, the program time shortening means 173, the program time extending means 174, the inter-part audio file silence adjusting means 175, and the speech speed converting means 176 are provided. Yes.

  A plurality of items synthesized by the item synthesizing unit 17b, that is, the audio of the produced program is referred to as a program audio file. In addition, information on the adjusted transmission time of each item adjusted by the program time adjusting means 17c will be referred to as program audio transmission control data.

  This program audio transmission control data is information for controlling the timing of transmitting a sentence (sentence audio data) included in each item based on the extension time added to the item and the shortened time deleted from the item. .

  The program time determination means 172 compares the total time of item transmission times with the program transmission time that is the time for transmitting the entire program, and determines whether the total time is longer or shorter than the program transmission time. Is.

  The program time shortening unit 173 compares the total time of the item transmission times by the program time determination unit 172 with the program transmission time, and determines that the total time is longer than the program transmission time. The total time is shortened based on the degree of stretch (ease of shrinkage, shrinkage level) set for each.

  The program time extension unit 174 compares the total transmission time of items by the program time determination unit 172 with the program transmission time, and determines that the total time is shorter than the program transmission time. The total time is extended based on the degree of stretch (easiness of elongation, elongation level) set for each.

  The part sound file silence adjusting means 175 connects the part sound files based on the result (determination result) obtained by comparing the total time obtained by adding the item sending times by the program time judging means 172 with the program sending time. (Silence time) is adjusted. By the way, before adjusting the time (silence time) when the component audio files are joined by the silence adjustment unit 175 between the component audio files, each component audio file is set by the component audio file silence interval setting unit 5a. Are connected according to basic silence intervals.

  Therefore, the silent sound adjusting unit 175 between the sound files of the parts reduces the basic silence interval uniformly when the total duration of the item transmission time is longer than the program transmission time based on the determination result by using the basic silence interval as a guide. The silent interval is adjusted, or the basic silent interval is shortened to be different depending on the punctuation mark and the reading point in the item. In addition, when the total transmission time of the items is shorter than the program transmission time, the inter-component audio file silence adjustment unit 175 uniformly adjusts the silence interval by increasing the basic silence interval, or within the items. Depending on the punctuation mark and the punctuation mark, the basic silence interval may be adjusted to a longer silence interval. For example, comparing the silence interval when there is a punctuation mark and the silence interval when there is a punctuation mark, the silence interval when there is a punctuation is usually adjusted to be longer.

  The speech speed conversion means 176 is a speech speed that is the speed at which the text voice data is read out based on the result (determination result) of comparing the total time obtained by summing the transmission times of items by the program time determination means 172 and the program transmission time. Is to convert. The speech speed conversion means 176 performs conversion so that the total time is shortened, that is, the speech speed is increased, when the total time of summing the transmission times of items is longer than the program transmission time. Also, the speech speed conversion means 176 performs conversion so that the total time becomes longer, that is, the speech speed becomes slower, when the total time of the item transmission times is shorter than the program transmission time.

  It should be noted that the technology relating to speech speed conversion employed in the speech speed conversion means 176 may be general and conventional as long as it does not impair voice quality, sound tone, or the like.

  In addition, the processing of each means (173 to 176) of the program time adjusting means 17c and the item exchanging operation (processing for changing an item to another item) by the program time adjusting means 17c are performed by the program time determining means 172. After the result (determination result) comparing the total transmission time for each program and the program transmission time for transmitting the entire program is output, the processing may be performed from any processing. In this case, which process is preferentially performed is set in advance.

  Here, the processing of the program time adjusting means 17c will be described with reference to FIGS. FIG. 4 is a diagram illustrating a case where the transmission time of each item is shortened when the total time of the transmission times of the items is longer than the program transmission time. FIG. 5 is a diagram illustrating a case where the transmission time of each item is extended when the total time of the transmission times of the items is shorter than the program transmission time.

  As shown in FIG. 4, in the program time adjusting unit 17c, the program time shortening unit 173 obtains the shortened time based on the shrinkage level set for each item scenario file, and the total time matches the program sending time. (Match) is adjusted. Here, the relationship between the sending time and the contraction level is described in a simplified manner. The contraction level of the second item from the left is “2”, and the contraction levels of the other items are “1”. The shortening time of the second item is twice that of the other items. The total transmission time after adjustment of each item matches the program transmission time.

  Further, as shown in FIG. 5, in the program time adjusting unit 17c, the program time extending unit 174 obtains the extension time based on the extension level set for each item scenario file, and the total time is the program transmission time. It is adjusted to match (match). Here, the relationship between the sending time and the elongation level is described in a simplified manner. The elongation level of the second item from the left is “2”, and the elongation levels of the other items are “1”. The stretching time of the second item is twice the stretching time of the other items. The total transmission time after adjustment of each item matches the program transmission time.

  FIG. 6 is a diagram for explaining the adjustment of the total time when the total time of the transmission times of the items is longer than the program transmission time within an allowable range. Here, the permissible range refers to a case where the lower limit times of the respective items are summed and within the program transmission time. That is, it is a case where the total time of the items can be matched with the program transmission time without replacing any item constituting the program with another item.

  As shown in FIG. 6, one program is composed of four items (a to d), and the total transmission time of these four items (ad) exceeds the program transmission time. The ease of contraction is set to “1”, the ease of contraction of item b is set to “2”, the ease of contraction of item c is set to “3”, and the ease of contraction of item d is set to “4”.

  In this case, the item d is most easily contracted, that is, it is easy to take a shortening time, and then the item c is easily contracted. Hereinafter, the item b is easily contracted in the order of the item a. Therefore, a reduction time (total reduction time) that can be deleted from each of the items (ad) is calculated so that the total transmission time of the items (ad) matches the program transmission time, and based on ease of contraction. And assigning a shortened time.

  FIG. 7 shows a result in which the total time obtained by summing the transmission times of the respective items is longer than the program transmission time within an allowable range, and the shortened time (total shortened time) is obtained and allocated based on the ease of contraction. It is a figure explaining adjustment of the total time when the item which allocated the shortening time reaches the minimum time. In FIG. 7, the lower limit time of the item is described as the minimum length.

  As shown in FIG. 7, one program is composed of four items (a to d), and the total transmission time of these four items (ad) exceeds the program transmission time. The ease of contraction is set to “1”, the ease of contraction of item b is set to “2”, the ease of contraction of item c is set to “3”, and the ease of contraction of item d is set to “4”.

  Here, first, a shortening time is assigned to the item d whose shrinkage is “4” and the item c whose shrinkage is “3”, so that these items d and c are either the minimum length or the actual length. It is shortened to the playback time (voice playback time + specified silence time). As a result, the item d and the item c cannot be shortened any more, and are excluded from the shortening target.

  Then, the excess shortening time is assigned to the item b of “2” for ease of shrinking, and the sending time after the adjustment of the items (a to d) is adjusted to match the program sending time. FIG. 7 shows only the case where the shortening time is allocated in the time adjustment when the item to which the shortening time is allocated reaches the lower limit time. For example, in each item, a component sound file and a component sound are included. The time of each item may be adjusted by adjusting the silence interval with the file in accordance with the ease of expansion and contraction of the basic silence interval.

  FIG. 8 shows that when the total time of the total transmission time of each item is longer than the allowable range and longer than the program transmission time, an alternative manuscript (another item) is inserted instead of one of the items. It is a figure explaining the case where it adjusts.

  As shown in FIG. 8, one program is composed of four items (a to d), and the total transmission time of these four items (ad) exceeds the program transmission time. The ease of contraction is set to “1”, the ease of contraction of item b is set to “2”, the ease of contraction of item c is set to “3”, and the ease of contraction of item d is set to “4”. Furthermore, the switching priority of item a is set to “1”, the switching priority of item b is “2”, the switching priority of item c is “3”, and the switching priority of item d is set to “4”. . Here, the higher the switching priority value, the higher the priority is set. However, the smaller the switching priority value, the higher the priority may be set.

  Here, a shortening time is assigned to the item d whose shrinkage is “4” and the item c whose shrinkage is “3”, and the item a whose shrinkage is “1” and the shrinkage is “2”. A shortening time is also assigned to the item b of “”. Then, the items d and c are shortened to the minimum length or the actual reproduction time. Therefore, first, the item c having the highest switching priority (switching priority 3) among the items (c, d) having the minimum length is switched to the substitute document, and a shortening time is assigned. Further, among items (c, d) having the minimum scale length, the item d having the next highest switching priority (switching priority 4) is switched to the alternative document, and the remaining shortening time is assigned.

  That is, when the total time of the transmission times of the items (a to d) is longer than the program transmission time beyond the allowable range, the shortening time is assigned according to the ease of contraction set for each item. At the same time, a substitute document (another item) is inserted instead of the item c and the item d, thereby matching the total time with the program transmission time.

  FIG. 9 shows a case where the total time of the transmission times of the respective items is shorter than the program transmission time within the allowable range, and when the total time is shorter than the program transmission time within the allowable range, and based on the ease of extension. It is a figure explaining adjustment of total time with the case where the item which allocated stretching time reached the upper limit time as a result of finding and allocating stretching time (total stretching time). In FIG. 9, the upper limit time is expressed as the maximum length.

  As shown in FIG. 9, one program is composed of four items (ad), and the total transmission time of these four items (ad) is shorter than the program transmission time, and the extension of item a The ease of “1”, the ease of extension of item b is set to “2”, the ease of extension of item c is set to “3”, and the ease of extension of item d is set to “4”.

  In this case, the item d is most easily stretched, that is, it is easy to take the stretching time, and then the item c is easily stretched. Hereinafter, the items b and the item a are easily stretched. Therefore, an extension time (total extension time) that can be added from each of the items (ad) is determined so that the total time of the transmission times of the items (ad) matches the program transmission time, and based on ease of extension. And extending time.

  As shown in FIG. 9 (a), when the total sum of the transmission times of the respective items is within the allowable range and shorter than the program transmission time, according to the ease of extension set for each item scenario file. The extension time is assigned to match the total time with the program transmission time.

  As shown in FIG. 9B, when the total sum of the transmission times of the respective items is shorter than the allowable range and shorter than the program transmission time, it depends on the ease of extension set for each item scenario file. The extension time is assigned and the extra extension time is assigned to the item so that the total time matches the program transmission time.

  First, the stretching time is assigned to the item d having the stretchability “4” and the item c having the stretchability “3”, and then the items d and c are stretched to the maximum length. As a result, since the items d and c cannot be stretched any more, they are not subject to stretching.

  Then, the surplus extending time is assigned before and after the item “b” of easiness of extension “2”, and the actual sending time of the items (ad) is adjusted so as to match the program sending time.

  FIG. 9 shows only the case where the extension time is allocated in the time adjustment when the item to which the extension time is allocated reaches the upper limit time. For example, in each item, a component audio file and a component audio are included. The time of each item may be adjusted by adjusting the silence interval with the file in accordance with the ease of expansion and contraction of the basic silence interval.

  Returning to FIG. The program audio storage means 19 is composed of a general recording medium such as a hard disk or a non-volatile memory, and stores the program audio file output from the program audio production means 17 and the program transmission control data. is there.

  The program audio transmission means 21 transmits the program audio file stored in the program audio storage means 19 in accordance with the program transmission control data. The program audio file selection means 21a, the item transmission timing automatic adjustment means 21b, the text Data output means 21c.

  The program audio file selection means 21 a selects the program audio file stored in the program audio storage means 19 in accordance with the program audio file operation signal output from the operation means 3.

  The item transmission timing automatic adjusting means 21b automatically adjusts the timing of sending the items of the program audio file for the program audio file selected by the program audio file selecting means 21a according to the program transmission control data, and externally. Output. That is, the item transmission timing automatic adjusting means 21b adjusts the interval between items based on the shortening time and the extension time obtained by the program time adjusting means 17c of the program audio production means 17, and is included in the item. Sending multiple voice data.

  The text data output means 21c outputs the text data of the program audio file to the display means 23. By outputting the text data of the program audio file to the display means 23 by the text data output means 21c, it is shown how a plurality of sentence audio data for each item produced by the program audio production means 17 are connected. It is possible to visually confirm what kind of program audio file is completed.

  The display means 23 is constituted by a general display, liquid crystal or the like, and includes an item scenario editor by the item scenario file setting means 5, a script editor by the script file setting means 9, and text data output means by the program audio sending means 21. The text data of the program audio file sent from 21c is displayed.

<Overall operation of program audio production device>
Next, the overall operation of the program audio production device 1 will be described with reference to the flowchart shown in FIG. 10 (see FIG. 1 as appropriate).
The program audio production device 1 is used in a weather forecast program or the like by referring to a broadcast audio dictionary composed of a plurality of component audio files created in advance by a component audio file cutout device (not shown). It is possible to easily produce the sound of a program that reads out many fixed sentences that only change the region, place name, or forecast content, or the sound of a program that combines complex sounds.

  In other words, the program audio production device 1 can be within broadcast time (program transmission time) by creating in advance a broadcast audio dictionary composed of component audio files obtained by extracting audio (audio data) uttered by an announcer or the like. Program audio can be created.

First, the program audio production device 1 sets each sentence included in the item set in the item scenario file by the item scenario file setting means 5, and sets the silence interval (pre-silence time, post-silence time) of the component sound file. Set (step S1). Subsequently, the program audio production device 1 sets a script file that defines the item sending order, the basic sending time for each item, and the program sending time by the script file setting means 9 (step S2).

  Then, the program audio production device 1 searches the component audio file by the item production means 17a of the program audio production means 17 (step S3), and synthesizes (continues) the items by the item synthesis means 17b (step S4). . Then, the program audio production device 1 adjusts the item transmission time (adjustment of the total time) by the program time adjustment unit 17c of the program audio production unit 17 (step S5), and the program audio file and the program time control data Are output to the program sound storage means 19 and stored by the program sound storage means 19 (step S6). A detailed description of the adjustment of the item transmission time will be given later with reference to the flowcharts shown in FIGS.

<Adjustment operation of transmission time in program audio production device 1>
Next, the operation for adjusting the transmission time for each item in the program audio production device 1 will be described with reference to the flowchart shown in FIG. 11 (see FIG. 1 as appropriate). In this adjustment operation,
The processing by the program time shortening unit 173 and the program time extending unit 174 is mainly performed.
First, the program audio production device 1 calculates the total (total time) of transmission times for each item by the program time determination unit 172 of the program time adjustment unit 17c in the program audio production unit 17 (step S11). Is equal to the program transmission time (step S12). If it is determined that they match (Yes in step S12), the sending time adjustment operation is terminated. If it is not determined that they match (step S12, No), the process proceeds to the next process (step S13).

  Subsequently, the program audio production device 1 determines whether or not the total time is longer than the program transmission time by the program time determination unit 172 of the program time adjustment unit 17c (step S13). When it is determined that the total time is longer than the program transmission time (step S13, Yes), the program audio production device 1 calculates the total reduction time by the program time reduction means 173 (step S14). Then, the program audio production device 1 determines, by the program time determination unit 172 of the program time adjustment unit 17c, whether or not the total of the lower limit times for each item is within the time obtained by subtracting the total shortened time from the program transmission time. (Step S15).

  When the program audio production device 1 does not determine that the total of the lower limit times for each item is within the time obtained by subtracting the total shortened time from the program transmission time (step S15, No), the program audio production device 1 is set for each item. The items are switched (substituted) according to the switching priority order (step S16), and the process returns to step S11.

  When it is determined that the total of the lower limit times for each item is within the time obtained by subtracting the total shortened time from the program transmission time (step S15, Yes), the program audio production device 1 sets the total shortened time for each item. (Step S17), and the sending time adjustment operation is terminated.

  If it is not determined in step S13 that the total time is longer than the program transmission time (No in step S13), the program audio production device 1 calculates the total extension time by the program time extension unit 174 ( Step S18). Then, the program audio production device 1 determines whether or not the total of the upper limit times for each item is equal to or more than the time obtained by adding the total extension time to the program transmission time by the program time determination unit 172 of the program time adjustment unit 17c. (Step S19).

  When the program audio production device 1 does not determine that the total upper limit time for each item is equal to or longer than the time obtained by adding the total extension time to the program transmission time (step S19, No), the program audio production device 1 is set for each item. The items are switched (substituted) according to the switching priority order (step S20), and the process returns to step S11.

  When the program audio production device 1 determines that the total upper limit time for each item is equal to or longer than the time obtained by adding the total extension time to the program transmission time (step S19, Yes), the total extension time is set for each item. (Step S21), and the operation for adjusting the sending time is terminated.

<Adjustment operation of transmission time in program audio production device 2>
Next, with reference to the flowchart shown in FIG. 12, the operation for adjusting the transmission time for each item in the program audio production device 1 will be described (see FIG. 1 as appropriate). In this adjustment operation,
The processing is mainly performed by the silent sound adjusting unit 175 and the speech speed converting unit 176.
First, the program audio production device 1 calculates the total (total time) of the transmission time for each item by the program time determination unit 172 of the program time adjustment unit 17c in the program audio production unit 17 (step S31). Is equal to the program transmission time (step S32). If it is determined that they match (Yes in step S32), the sending time adjustment operation is terminated. If it is not determined that they match (step S32, No), the process proceeds to the next process (step S33).

  Subsequently, the program audio production device 1 determines whether or not to adjust between the component audio files by the program audio production means 17 (step S33), and determines to adjust between the component audio files. In this case (step S33, Yes), the part sound file silence adjustment unit 175 adjusts the part sound file interval (silence time) so that the total sending time matches the program sending time (step S34). ).

  When the program audio production unit 17 does not determine that the program audio production unit 17 adjusts between the component audio files (No in step S33), the program audio production unit 17 adjusts the speech speed by using the speech rate conversion unit 176. The total transmission time is made to match the program transmission time (step S35).

  According to the program audio production device 1, the program audio production means 17 is referred to a broadcast audio dictionary formed by collecting component audio files output from a component audio file cutout device (not shown), and based on the item scenario file. The parts audio files are joined together to produce each sentence of the item, and the items are arranged in the order of transmission based on the script file, and the program audio file is produced. Audio such as audio used for the program can be produced.

  Also, according to the program audio production device 1, by receiving the code data by the code data receiving means 13, the program audio production means 17 can produce items based on this code data.

  Furthermore, according to the program audio production device 1, the program time adjustment unit 17c of the program audio production unit 17 determines whether the total transmission time for each item is longer or shorter than the program transmission time for sending the entire program. If it is long, the shortening time to be subtracted from the sending time is calculated based on the degree of elasticity. Also, when the total transmission time for each item is shorter than the program transmission time for transmitting the entire program, the extension time to be added to the transmission time is calculated based on the degree of expansion / contraction. For this reason, a program audio file can be produced so as to be within the program transmission time.

  Furthermore, according to the program audio production apparatus 1, when the program audio transmission means 21 transmits the program audio file, the timing at which each item is transmitted is adjusted based on the program audio transmission control data. The program transmission time for transmitting the entire program, that is, the actual broadcast time can be adjusted.

  In addition, according to the program audio production apparatus 1, the program audio production means 17 sends out the total of the transmission time for each item and the program as a whole by the silent sound adjustment means 175 between the component audio files of the program time adjustment means 17c. A program audio file can be produced so as to be within the program transmission time by adjusting the time when the component audio files are connected based on the determination result of determining whether the times match.

  Further, according to the program audio production apparatus 1, the total transmission time for each item is equal to the program transmission time for sending the entire program by the speech speed conversion unit 176 of the program time adjustment unit 17c in the program audio production unit 17. By converting the speed at which the text audio data is read out based on the determination result of determining whether or not the program has been performed, a program audio file can be produced so as to be within the program transmission time.

  Alternatively, the program audio production device 1 creates the text audio data by connecting the component audio files, and displays the result of the time adjustment on the display means 23 by the text data output means 21c. Can be confirmed visually without hearing the sound of the program audio file actually produced.
