Embodiment 1
FIG. 1 is a diagram for explaining the configuration of an audio data providing system according to Embodiment 1 of the present invention.
This speech data providing system performs speech synthesis processing using the voice feature data of a specific speaker on the utterance content of the voice message specified by the orderer, and provides the resulting speech synthesis data as custom-made speech data The system is roughly divided into the following: the voice characteristics of the orderer 1 who orders voice data generation, and the voice characteristics of the speaker who requests the orderer 1 to speak the desired voice message. Voice synthesizing process using data, and voice data obtained thereby is provided to the ordering party 2, the network 3 interposed between the ordering party 2 and the ordering party 1, selection of the ordering party 1 The voice right holder 4 having the right of the voice of the speaker who has been selected.

In FIG. 1, an orderer 1 uses this voice data providing system to request creation of his / her favorite voice message, and a device (table clock or the like) or recording medium in which the created voice message is recorded. Purchase a CD-ROM (such as a CD-ROM) and use it on your own, or receive the voice message via the network and use your own information terminal (PC or mobile phone)
In addition to the person who downloads and uses the device, the device and the recording medium itself include those who purchase it for the purpose of gifts without using it themselves. A case where the message is used by itself will be described as an example.

The order receiving side 2 may be a manufacturer that manufactures a device in which audio data is to be embedded, or may be a service provider that specializes in providing audio data. In the case of a service provider, it is possible to create audio data and provide the audio data to a device manufacturer or general user, and of course, the device is supplied from the device manufacturer and the audio data is incorporated into the device. It is also possible to do so far.

Further, the delivery form of the voice data created on the order receiving side 2 to the orderer (for example, the orderer 1) may be delivered in a state of being incorporated in the device 5 such as a table clock, for example. -The form delivered in the state recorded on recording media 6, such as ROM, may be sufficient.
Also, a certain orderer (for example, the orderer 1) has his information terminal (PC) via the network 3.
Or a delivery form such as downloading to a mobile phone).

By the way, the order receiving side 2 has an audio data creation device 20. The voice data creation device 20 selects the voice message desired by the orderer 1, that is, the utterance content (text data) keyed by the orderer 1 from his / her PC in the embodiment of the present invention and the orderer 1 selects. The speech synthesis data is created using the speech feature data of the speaker. Before the speech synthesis process, the speech content of the voice message input by the key of the orderer 1 is the speech content of the selected speaker. It is determined whether or not it is composed of expressions that are allowed to be used (this is called permitted vocabulary / utilization here), and expressions that are permitted to be used as the utterance content of the speaker (usable vocabulary / utilization) The speech synthesis process is performed only when it is determined that the
The detailed configuration and operation will be described later in detail.

The voice right holder 4 is a so-called celebrity such as an actor, a singer, a voice actor, or a sports player. These individual celebrities may be individuals who are voice rights holders 4, but in the case of actors, singers, voice actors, etc., the office (production, etc.) to which each belongs is the voice rights holder 4. In some cases. Similarly, in the case of other celebrities, the office to which each belongs may become the voice right holder 4.

In such a configuration, the processing procedure will be described briefly. The orderer 1 accesses the voice data creation order receiving site on the order receiving side 2 with his / her PC or the like, and a service form such as what service is received (this service) In this case, a request to create a voice message is selected, the utterance content of the voice message is key-input from the PC, and a speaker to whom the voice message is desired to be uttered is selected (speaker selection). .

The order receiving side 2 performs speech synthesis processing using the text data of the utterance content of the voice message keyed by the orderer 1 and the voice feature data of the speaker selected by the orderer 1, and the resulting voice is obtained. The orderer 1 as synthesized data corresponding to the voice message.
To provide.

At this time, as described above, the utterance content of the voice message input by the orderer 1 is an expression permitted to be used as the utterance content of the speaker selected by the orderer 1 (usage permitted vocabulary /
If it is determined that it is composed of the permitted vocabulary and utilization corresponding to the speaker, the right holder 4 of the voice corresponding to the speaker selected by the orderer 1 is determined. If the use permission is obtained, the speech synthesis process is performed using the voice feature data of the speaker and the utterance content (text data) of the voice message input by the orderer 1. Then, the voice synthesis data obtained thereby is recorded in the storage means mounted on the purchaser 1's desired purchase device, and the device 5 is provided to the orderer 1 or is stored in a recording medium 6 such as a CD-ROM. The recorded data is provided to the orderer, or the speech synthesis data itself is transmitted to the orderer and the orderer 1 downloads it to his / her information terminal. Details will be described below.

FIG. 2 is a configuration diagram of the voice data creation device 20 provided on the order receiving side 2, and a sentence analysis unit 21.
Grammar data 22, prosody control unit 22 as speech synthesis processing unit and speech waveform generation unit 2
3 and utterances of a large number of speakers (speaker # 1, speaker # 2,..., Speaker #n) such as actors, singers, voice actors, and athletes described in the order receiving side 2 Usage permission expression dictionaries 251, 252,... As usage permission expression recording means in which expressions permitted to be used are recorded as contents.
, 25n, prosody data 261, 262,..., 26n and sound quality data 271, 272,... Which are voice feature data for the speaker # 1, speaker # 2,.
.., 27n.

, 25n include individual speaker # 1, speaker # 2,.
... Expressions that are permitted to be used as utterance contents of speaker #n (usable vocabulary / utilization) are described.

The sentence analysis unit 21 receives the utterance content (text data) of the voice message input by the orderer 1 and uses the grammar data 22 such as a grammar dictionary or a Japanese vocabulary dictionary to analyze the sentence (syntax analysis or morphological analysis). ), And the sentence analysis result is used for the speaker selected by the orderer 1 and the permitted expression dictionary for the speaker (speaker # 1, speaker # 2,..., The permitted expression dictionary for speaker #n is used. 251 to 25n), it is determined whether or not the utterance content of the voice message input by the orderer 1 is composed of the permitted vocabulary and utilization for the selected speaker. If it is determined that it is composed of permitted vocabulary and utilization for the selected speaker,
The sentence analysis result is passed to the speech synthesis processing unit (prosody control unit 23 and speech waveform generation unit 24) which is the next processing step.

When it is determined that the utterance content of the voice message input by the orderer 1 has an expression other than the permitted vocabulary / utilization for the selected speaker (this will be referred to as an unknown word). Notifies the orderer 1 to that effect and presents to the orderer 1 which is an unknown word.

Further, the prosody control unit 23 and the speech waveform generation unit 24 as the speech synthesis processing unit include the sentence analysis unit 2.
1, the voice feature data of the speaker selected by the orderer 1, that is, the speaker # 1, the speech, for the sentence analysis result of the utterance content (text data) of the voice message determined to be an appropriate expression Of prosody data 261 to 26n for speaker # 2,..., Speaker #n, prosody data corresponding to the speaker, speaker # 1, speaker # 2,. Voice quality data 271-27
Speech synthesis processing is performed using voice quality data corresponding to the speaker among n, and speech synthesis data is output.

Such a configuration will be described in more detail with reference to FIG. 3 using a specific example. The orderer 1 accesses the voice data creation ordering site of the order receiving side 2 with his / her PC etc., and requests the creation of a voice message in which the utterance content of the voice message prepared by himself is uttered by the voice of his favorite speaker. In addition, it is requested to record the voice message in a storage unit of a certain device (table clock, etc.) 5.

The utterance content of the voice message here is, for example, the content of “It's already morning, do n’t wake up”, and selects an idol singer (speaker # 1) as the speaker who utters the content. And

The orderer 1 inputs the utterance content of the voice message with his / her PC, and selects a certain idol singer (speaker # 1) as a speaker who utters it. As a result, the text data corresponding to the utterance content “Another morning wake up idiot” of the voice message key-input by the orderer 1 becomes the document analysis unit 21 of the voice data creation device 20 on the order receiving side 2.
, And speaker selection information indicating that the speaker # 1 is selected is input to the document analysis unit 21.

The document analysis unit 21 performs morphological analysis as document analysis using grammatical data (consisting of a grammar dictionary, a Japanese vocabulary dictionary, etc.) 22 for the input text data (step S).
1) Part-of-speech decomposition is performed to obtain a morphological analysis result (step S2).

Then, the morpheme analysis result as shown in step S2 of FIG. 3 is compared with the use permission expression dictionary 251 for the speaker # 1 selected by the orderer 1, and the individual elements and use permission expressions subjected to morphological analysis are used. A match between the contents described in the dictionary 251 is determined (step S3). In this case, the use permission expression dictionary 251 for the speaker # 1 has “already” as the use permission vocabulary / utilization.
, “Morning”, “da”, “yo”, etc. are described, but “get up” and “sleep” are not described.

Therefore, in this example, “other”, “morning”, “da”, and “yo” are determined to be appropriate as the content of the speaker # 1, but “get up” and “sleep” Is determined to be an expression (unknown word) that is not described in the use permission expression dictionary of the corresponding speaker # 1, and in this case, “already”, “morning”, “da”, “Yo” is extracted (step S4).

As described above, when it is determined that an unknown word that is not described in the use permission expression dictionary 251 of the speaker # 1 is included, the speech synthesis process that is the next processing step does not proceed and the unknown word is included. Is notified to the orderer 1 and the determination result is presented to the orderer 1 (
Step S5).

As the determination result presented to the orderer 1, for example, as shown in step S 5 of FIG. 3, the unknown words “wake up” and “
Each character part of “Baka” can be represented by a circle. In addition, as a way of expressing this unknown word,
In addition, various methods such as making unknown words bold, increasing the size of characters, changing the font, etc. are conceivable.

The orderer 1 receives such a determination result, knows that there is an unknown word for the speaker # 1 (a certain idle singer) in the utterance content of the voice message input by his key, corrects the unknown word, If it is entered as a key content such as “Wake me up in the morning,” the above-described steps S1 and S2 are performed again.

That is, the morphological analysis is performed on the text data “Wake me up in the morning” and the morphological analysis results are obtained (steps S1 and S2). Then, the morpheme analysis result is checked against the use permission expression dictionary 251 for the speaker # 1 selected by the orderer 1, and it is determined whether each element subjected to the morpheme analysis matches the contents of the use permission expression dictionary 251. (Step S3). In this case, the usage permission expression dictionary 251 for the speaker # 1 includes “wake up” and “ne” in addition to “already”, “morning”, “da”, “yo” as usage permission vocabulary / utilization. Etc. are described.

Therefore, since all of the vocabulary and usage that make up “get it up in the morning” are described in the use permission expression dictionary 251, the utterance content of the voice message is the content of the utterance of the speaker # 1. Determined to be appropriate.

As described above, when it is determined that the utterance content of the voice message is appropriate as the utterance content of the speaker # 1, the speech synthesis processing which is the next processing step is started. This speech synthesis process is performed by the prosody control unit 23 and the speech waveform generation unit 24. That is, "It's already morning, get up"
Using the sentence analysis result for the text data, the prosodic data 251 for the speaker # 1 and the voice quality data 261 for the speaker # 1, speech synthesis processing is performed and speech synthesis data is output.

This speech synthesis data is recorded in the storage means of the table clock that the orderer 1 intends to purchase here. As a result, for example, if the time of the voice message is set to 7:00 am as the output timing of the voice message, the clock will be spoken with the voice of speaker # 1 (an idol singer) at 7 am every morning. The voice message “Wake me up in the morning” is output.

In step S3, if it is determined that the utterance content of the voice message prepared by the orderer 1 is composed of appropriate vocabulary and usage, as described above, the speech synthesis process starts.
At this time, a request for permission to use the voice feature data (prosodic data, voice quality data, etc.) is issued to speaker # 1 (voice holder 4) who utters the voice message (see FIG. 1). When a use permission notice (see FIG. 1) is obtained from the voice right holder 4 side, voice synthesis processing using the voice feature data (in this case, prosodic data 261 and voice quality data 271) is performed.

Thus, when using the voice feature data of a certain speaker, the order receiving side 2 pays the usage fee (which may vary depending on the individual speaker) to the right holder 4 of the voice.

In addition, when using the voice feature data of a certain speaker, a request for permission for use is issued from the order receiving side 2 each time, and in response to the request, a permission notice is received from the right holder 4 of the voice. If it is determined that there is no inappropriate content in the voice message prepared by the orderer 1,
The voice corresponding to an agreement that allows the voice data creation device 20 to issue only a license request to the voice right holder 4 and to create voice synthesis data using the voice feature data of the speaker. It is also possible to exchange with the right holder 4. In that case, the voice right holder 4 can grasp the number of times of use of his / her voice feature data by the use permission request from the order receiving side 2 and can charge based on the use frequency.

The voice message creation fee from the orderer 1 to the order receiving side 2 can be paid by various methods such as payment at a convenience store, payment by bank transfer, and payment by credit card.

Further, the contents of the use permission expression dictionary can be made different for each speaker # 1, # 2,..., #N. For example, the range of expressions allowed varies depending on whether the speaker is a woman or a man, or even the same man, depending on the young idol singer and the elderly action actor. For each speaker, by preparing a use permission expression dictionary with vocabulary and usage descriptions within the allowable range for each speaker, taking advantage of the individuality of each speaker, It can be determined whether or not the utterance content is appropriate.

As described above, according to the first embodiment, the utterance content of the voice message designated by the orderer 1 (key input here) is used for the selected speaker (here, speaker # 1). It is judged whether or not it is composed of permitted vocabulary / utilization described in the expression dictionary 251, and if an expression (unknown word) other than the permitted vocabulary / utilization is included, it is presented to the orderer 1. The orderer 1 sees it and creates the utterance content of the voice message with the unknown word corrected and sends it to the order receiving side 2, and the order receiving side 2 again selects the selected story for the corrected voice message. It is determined whether or not it is composed of the vocabulary / utilization described in the use permission expression dictionary 251 for the speaker (here, speaker # 1), and composed of the use permission vocabulary / utilization described in the use permission expression dictionary 251 Only when it is determined that The speech content of the voice message by speech synthesis process using the speech feature data of the speaker, and to output the speech synthesis data.

This prevents problems such as causing the speaker to speak unintentionally inappropriate content by celebrities (voice rights holders) such as actors, singers, voice actors, and athletes, and hurting the speaker's honor. And service providers who provide such voice data providing services (
The ordering side 2) is no longer suspected of good sense as a service provider.

In the first embodiment, since it is determined that the utterance content of the voice message is composed only of the permitted vocabulary / utilization set for each speaker, it is possible to shift to the voice synthesis process. Although the content of the message utterance is limited to some extent, the adequacy of the speaker as the utterance content can be increased accordingly, and a sense of security can be given to the speaker as the right holder of the voice. Further, since only a voice message having an appropriate content for each speaker is created, a service provider (order receiving side) that performs such a voice data providing service can also improve evaluation as a service provider.

In addition, according to the vocabulary that can be used as utterance content for individual speakers and a method to describe utilization,
For example, there is an effect that it is easy to deal with when a new word or buzzword is generated. For example, if you want to describe a buzzword at that time for a certain speaker, you can create the utterance content of a voice message that includes the buzzword if you describe the buzzword as a permitted vocabulary / utilization. .

[Embodiment 2]
In this second embodiment, as the use permission expression recording means for recording the expression permitted to be used as the utterance content of the speaker, for speaker # 1, speaker # 2,. , 25n, as shown in FIG. 4, network grammar 281 for each speaker # 1, speaker # 2,..., Speaker #n, as shown in FIG. , 282, ...
, 28n is shown. Since other components are the same as those in FIG. 2, the same parts are denoted by the same reference numerals. Hereinafter, the second embodiment will be described.

The network grammar can be expressed in a number of ways by connecting each morpheme from the left end (begin) to the right end (end X direction) as shown in FIG. Can be generated.

In the example of Fig. 5, for example, "Wake up already in the morning", "Wake up already in the morning", "Please go to bed already at night", "Wake up at * * △ minutes in the morning", etc. By combining the morphemes that make up the network grammar, the utterance content of various voice messages can be generated. However, compared to the example of the first embodiment, the number of utterance contents of a voice message that can be generated is limited, but since the utterance contents of a voice message that can be generated can be easily grasped, an undesirable utterance content is created. The possibility is extremely low, and it has the effect of giving the speaker a sense of security as the right holder of the voice. Further, since only a voice message having an appropriate content for each speaker is created, a service provider (order receiving side) that performs such a voice data providing service can also improve evaluation as a service provider.

In FIG. 5, “*” and “△” such as “* hour” and “△ minute” are
Any number representing the time can be inserted.

Such a network grammar is prepared for each speaker. And orderer 1
For example, in the same manner as in the first embodiment described above, an idol singer (speaker # 1) is inputted as a speaker who inputs the utterance content of a voice message “It's already morning, wake up!”
)) Is selected. The network grammar 281 for speaker # 1 is shown in FIG.
It is assumed that

The document analysis unit 21 uses grammatical data (consisting of a grammar dictionary or a Japanese vocabulary dictionary) 22 for the input text data, performs morphological analysis as document analysis, decomposes the part of speech, and obtains the morphological analysis result. (See step S2 in FIG. 3).

Then, this morphological analysis result is used as a network grammar 2 for speaker # 1 selected by the orderer 1.
The corresponding morpheme is traced from the left end (begin) using 81 (see FIG. 5). In this example, morphemes can be matched up to “already”, “morning”, and “dayo”, but “wake up” and “fool” input by the orderer 1 are described in the network grammar 281. Therefore, it is determined that “Wake up” and “Baka” are unknown words as expressions spoken by the speaker # 1.

As described above, when it is determined that an unknown word that is not described in the use permission expression dictionary of the speaker # 1 is included, the speech synthesis process that is the next processing step does not proceed and the unknown word is included. Is notified to the orderer 1 and the determination result is presented to the orderer 1.

As described above, the determination result presented to the orderer 1 is, for example, each character part of the unknown words “wake up” and “idiot”, for example, “It's already morning! It can be considered that is represented by ○. As other ways of expressing the unknown word, various methods such as making the unknown word bold, increasing the size of the character, changing the font, etc. are conceivable.

The orderer 1 receives such a determination result, knows that there is an unknown word in the utterance content of the voice message entered by his key, corrects the unknown word, and says, “Wake me up in the morning” Assuming that it is keyed in as content, this time morphological analysis is performed on the text data of “Wake me up in the morning”, the morphological analysis result is obtained, and the morphological analysis result is selected by the orderer 1 As described above, using the network grammar 281 for the speaker # 1
Trace the corresponding morpheme from begin). In this case, all the morphemes of “already”, “morning”, “dayo”, “wake up”, “ne” match the morphemes that make up the network grammar. The utterance content of “Ne” is determined to be appropriate as the utterance content of the speaker # 1.

As described above, when it is determined that the utterance content of the voice message is appropriate as the utterance content of the speaker # 1, the speech synthesis processing which is the next processing step is started. Since it has already been described in Embodiment 1, the description thereof is omitted here.

As described above, the second embodiment using the network grammar has a larger restriction on the utterance content of the voice message that can be generated compared to the first embodiment, but the corresponding utterance content of the speaker is further increased accordingly. It is possible to give the speaker a sense of security as a voice right holder.

In the second embodiment, when the orderer selects a speaker, the network grammar for the speaker is presented to the orderer, and the orderer looks at the network grammar and makes his / her own desire. A voice message may be created.

For example, if the orderer 1 selects the speaker # 1, the network grammar 301 for the speaker 31 is transmitted to the orderer 1 side, and the orderer 1 sees it on his / her PC and sees the PC screen. Above,
For example, if you click “May”, “Morning”, “Dayo”, “Wake up”, “Ne” in order, the voice message utterance content will be “Wake up already in the morning” It can also be input to the contractor 2 side.

According to this, since the utterance content of the voice message created by the orderer 1 is in accordance with the network grammar, unknown words are not used, and the creation processing of the utterance content of the voice message is easy. As a result, the entire process including the speech synthesis process can be performed efficiently.

Further, the individual morphemes constituting the network grammar may not be fixed depending on the contents of the morphemes but may be selectable by the orderer from several. For example, as described above, the time, date, etc. are indicated as “* hour”, “△ minute”, “* month”, “△ day” as “*”, “
△ ”can be entered as an arbitrary number representing the time or date (may be selected from a pull-down menu).
It is also possible to prepare several expressions similar to that and suitable for the speaker so that they can be selected. In this way, variations in expression can be made more diverse.

The network grammar can also have different contents depending on the individual speakers # 1, # 2,. For example, the range of expressions allowed varies depending on whether the speaker is a woman or a man, or even the same man, depending on the young idol singer and the elderly action actor. By preparing a network grammar that describes the vocabulary and usage within the allowable range for each speaker, the content of each speaker's utterance is utilized, taking advantage of the individuality of each speaker. It can be determined whether or not it is appropriate.

As described above, in the second embodiment, similarly to the first embodiment, only a voice message having an appropriate content for each speaker is created. Therefore, a service provider (order receiving side) that performs such a voice data providing service. ) Can also be evaluated as a service provider, and for example, an effect can be easily obtained when a new word or buzzword is generated.

[Embodiment 3]
In the first embodiment and the second embodiment described above, when the order receiving side 2 presents a determination result indicating the presence of an unknown word to the orderer 1, the orderer 1 looks at the presented content and sets the unknown word to himself / herself. However, in the third embodiment, use permission expression dictionaries 251, 252,..., 25 n for speakers # 1, # 2,. Or speakers # 1, # 2, ...
In addition to the network grammars 281, 282,..., 28 n for the #n (second embodiment), the unknown word conversion dictionaries 291, 292, #n for the speakers # 1, # 2,. .., 29n, and if there is an unknown word in the utterance content of the voice message keyed in by the orderer 1, a conversion candidate for converting the unknown word to each speaker Can be presented to the orderer 1.

FIG. 6 is a diagram showing the configuration of the voice data creation device 20 in the third embodiment. Here, the configuration of FIG. 2 used in the first embodiment is for speakers # 1, # 2,. , 29n are provided as examples of unknown word conversion dictionaries 291, 292,. 6 is different from the block diagram shown in FIG. 2 in the unknown word conversion dictionaries 291, 292,.
.., 29n are different except that the rest is the same as FIG. 2, and the same components as those in FIG. 2 are denoted by the same reference numerals.

As described above, the unknown word conversion dictionaries 291, 292,..., 29 n can convert any unknown word into any expression when there is an unknown word in the utterance content of a voice message to be uttered by a certain speaker. This is a dictionary in which conversion candidates are good. Hereinafter, a specific example of the third embodiment will be described with reference to FIG.

The orderer 1 accesses the voice data creation order receiving site of the order receiving side 2 with his / her PC or the like, and utters the voice message prepared by himself / herself with the voice of his / her favorite speaker as in the first embodiment. Assume that a request is made to create a voice message and the voice message is recorded in the storage means of a certain device (table clock, etc.) 5.

The utterance content of the voice message here is the same as that used in the first embodiment, and it is the content of “It's already morning, do n’t wake up”, and the utterance content of the voice message is keyed by your own PC, Assume that a certain idol singer (speaker # 1) is selected as the speaker who speaks it. As a result, the text data corresponding to the utterance content of the voice message entered by the key of the orderer 1 "Morning is the morning" is input to the document analysis unit 21 of the order receiving side 2 and the speaker # 1 is selected. Speaker selection information indicating this is input to the document analysis unit 21.

The document analysis unit 2 performs morphological analysis on the input text data as document analysis using grammatical data (consisting of a grammar dictionary, a Japanese vocabulary dictionary, etc.) 22 (step S11).
), The part-of-speech decomposition is performed to obtain the morphological analysis result (step S12).

Then, the morphological analysis result as shown in step S12 in FIG. 7 is compared with the use permission expression dictionary 251 for the speaker # 1 selected by the orderer 1, and the individual elements and use permission expressions subjected to the morphological analysis are used. A match between the contents of the dictionary 251 is determined (step S13). In this case, the use permission expression dictionary 251 for the speaker # 1 has “already” as the use permission vocabulary / utilization.
, “Morning”, “da”, “yo”, etc. are described, but the use of command forms such as “get up” and “sleep” is not described.

Therefore, in this example, “already”, “morning”, “da”, and “yo” are described in the use permission expression dictionary 251 of the speaker # 1, and therefore the content of the speaker # 1 speaks. However, “Wake up” and “Sleep” are determined to be unknown words that are not described in the permitted permission expression dictionary of the speaker # 1, and in this case, as permitted permission vocabulary and utilization "Already","
“Morning”, “da”, and “yo” are extracted (step S14).

As described above, when it is determined that an unknown word that is not described in the use permission expression dictionary of the speaker # 1 is included, the sentence analysis unit 21 does not proceed to the speech synthesis process that is the next processing step, and Then, using the unknown word conversion dictionary 281 for the speaker # 1, the expression conversion (vocabulary / utilization conversion) of what the inappropriate expression should be is performed (step S15).

In this case, the unknown word conversion dictionary 291 for speaker # 1 describes that “blank” and “aho” are expressed as “blank”, and “wake up” and “ As for the expression of the command form such as “sleep”, it is described that it is converted into expressions such as “get me up”, “get me up”, “get me up”, and “get me up”.

In addition, the expression “blade” or “aho” is “blank” because it is difficult to paraphrase these people and deface them with other appropriate expressions.
It is because it is not preferable to use such an expression even if it can be paraphrased by another expression even if the expression is slandering. Also, a little rough command forms such as “get up” and “sleep” are the expressions that such an idol singer would prefer such expressions. Here, “get up”, “get me up”, “sleep” It is supposed to be converted into expressions such as “Tene” and “Give me a sleep”.

When this unknown word conversion is completed, the orderer 1 is presented as to where and how to convert it (step S15). In this case, the utterance content of the voice message including the unknown word “It's already morning, get up” prepared by the orderer 1 is, as shown in step S16 of FIG. “Wake up” and present two candidates, “Wake me up in the morning,” to the orderer 1 as second candidates.

In this case, the unknown words “Wake up” and “Baka” are used in order to notify the orderer that the unknown words are unknown words. Various methods, such as `` It's morning '' ○○○ ○○ '', each character part of unknown word is indicated by ○, bold, the size of the character is increased, the font is changed, etc. It is done.

Thus, by performing the unknown word conversion process using the unknown word conversion dictionary 291, in this case, the first candidate “Wake up already in the morning” and the second candidate “Wake up in the morning” "
Is displayed to the orderer, and the content of these contents is deleted from the expression “idiot”. As described above, the unknown word conversion dictionary 291 for the speaker # 1 has “baka” and “
This is because the expression “aho” is described as “blank”.

The orderer 1 receives such a notification, knows that there is an unknown word in the utterance content of the voice message prepared by him, selects the first candidate presented by the order receiving side 2, If the contents such as “Tene” are key-inputted, in the voice data creation device 20 of the order receiving side 2, the document analysis unit 21 performs morphological analysis on the text data “Wake me up in the morning” and the morphological analysis A result is obtained (steps S11 and S12). Then, the morpheme analysis result is checked against the use permission expression dictionary 251 for the speaker # 1 selected by the orderer 1, and it is determined whether each element subjected to the morpheme analysis matches the contents of the use permission expression dictionary 251. (Step S13). In this case, the usage permission expression dictionary 251 for the speaker # 1 includes “
It is assumed that “get up”, “ne”, etc. are described in addition to “other”, “morning”, “da”, “yo”.

Therefore, since all of the vocabulary and usage that make up “get up already in the morning” are described in the use permission expression dictionary 251, the utterance content of the voice message is the utterance of the speaker # 1. It is determined that the content is appropriate.

In this case, two candidates from the order-receiving side 2 are presented to the orderer 1, and the orderer 1 looks at it, selects his / her favorite expression from the candidates, and includes the candidate. Although the entire message utterance content key is input again, it is not necessary to re-key the entire utterance content of the voice message, and only information on which candidate is selected may be sent to the order receiving side 2.
For example, in this case, by sending information that the orderer 1 selects the first candidate to the order receiving side 2, the order candidate 2 then has the first candidate “Wake up already in the morning”. It is determined that the utterance content of the voice message desired by the orderer 1 is performed, the voice synthesis process as the next process is performed, and the voice synthesized voice data is recorded in the recording means of the device 5.

The processing after the speech synthesis processing is the same as that in the first embodiment, and since it has already been described in the first embodiment, the description thereof is omitted here.

The contents of the unknown word conversion dictionaries 281, 282,.
2, ..., #n can be different, for example, whether the speaker is a woman or a man, or even a young idol singer and an elderly action The range of allowable expressions varies depending on the actor, etc., so an unknown word conversion dictionary corresponding to the range is created.

As described above, according to the third embodiment, the utterance content of the voice message prepared by the orderer 1 by himself / herself is not described in the use permission expression dictionary 251 for the speaker selected by the orderer 1. If a word is included, a conversion candidate for the unknown word is prepared by the order receiving side 2 and presented to the orderer 1. As a result, the orderer 1 knows at a glance how to correct the unknown word, so that it becomes easy to create the utterance content of the voice message for each speaker to be uttered.

Further, as in the first embodiment, only when it is determined that the speech content is an appropriate speech message, speech synthesis processing is performed using the speech feature data of the speaker, and speech synthesis data is output. Therefore, there is a problem that the speaker's unintentional inappropriate contents such as actors, singers, voice actors, athletes, etc. are not intended, and that the speaker's honor is hurt. As a result, the service provider (order receiving side 2) that provides such a voice data providing service is not suspected of the common sense as the service provider.

Although the example in which the unknown word conversion process is applied to the first embodiment has been described here, it is needless to say that the unknown word conversion process can also be applied to the second embodiment.

[Embodiment 4]
In each of the above-described embodiments, the speaker utters a Japanese voice message using the utterance content of the Japanese voice message prepared by the orderer 1 and the voice feature data of the speaker selected by the orderer 1. In the fourth embodiment, the orderer 1 has been described.
It is possible to make the language used for the utterance content of the prepared voice message different from the language of the synthesized voice message.

For example, the orderer 1 inputs the utterance content of the Japanese voice message “Morning is the morning,” used in each of the above-described embodiments, and uses the voice feature data of the speaker # 1 to input English. It is also possible to request creation of a voice message. Hereinafter, this Embodiment 4 is demonstrated easily, referring FIG. Here, an example applied to the first embodiment will be described.

FIG. 8 is a diagram showing the configuration of the audio data creation apparatus 20 of the fourth embodiment, and the document analysis unit 2
The other components are the same as those in FIG. 2 except that the language conversion unit 30 is provided on the output side of FIG.

The language conversion unit 30 can convert (translate) a certain language into a language designated by the orderer 1. In the third embodiment, Japanese can be converted into another language. In this case, a language that can be converted (translated), such as Japanese to English, may be determined in advance as one language, but it is possible to convert from Japanese to multiple languages, and from among the multiple languages Orderer 1
May be able to specify the language to be converted.

When the orderer 1 can specify a language to be converted from a plurality of languages as described above, the orderer 1 performs key selection of the utterance content of the voice message and selects the speaker, and further , Language selection. For example, when requesting creation of a voice message in English, English is selected as the language.

Here, it is assumed that the orderer 1 key-inputs “another morning wake up fool” used in the first embodiment as the voice message utterance content, selects the speaker # 1, and further selects English as the language. To do. As a result, the text data and speaker selection information of “It's morning wake up” is input to the document analysis unit 21, and the language selection information is input to the language conversion unit 30.

The document analysis unit 21 performs document analysis processing as described in the first embodiment,
It is determined whether or not there is an inappropriate expression as the content of the speaker # 1 in the utterance content of the input voice message. However, since these processes have already been described in detail, the description is given here. Omitted. Then, if there is an inappropriate expression, it is corrected. For example, as described above, it is corrected to “Get up already in the morning”, and if it is determined that there is no inappropriate expression, the voice The language conversion unit 30 performs language conversion (in this case, Japanese is converted into English) using the document analysis result for the utterance content of the message.

Then, the prosody control unit 23 and the speech waveform generation unit 24 perform speech synthesis processing using the prosody data for the speaker # 1 and the speech waveform data for the speaker # 1 with respect to the utterance contents of the language-converted speech message. A voice message with “Wake me up in the morning” translated into English is output.

In this way, the utterance content of the Japanese voice message prepared by the orderer 1 is converted into the language specified by the speaker (in this case, English), and the utterance content of the English voice message is selected by the orderer 1. The speech synthesis process is performed using the voice feature data of the speaker who has played, and the speech synthesis data is output. In this case, the utterance content of the voice message “Wake me up in the morning!” 1 can speak in English.

In addition, although the example of Embodiment 1 was demonstrated here, in the case of Embodiment 2 and Embodiment 3, it can implement similarly. Further, the language after conversion is not limited to English, and may be another language.

As described above, according to the fourth embodiment, the language conversion unit that converts the utterance content of the voice message designated by the orderer into another language is provided, and the utterance content of the voice message is converted into the orderer by the language conversion unit. Can be translated into a language designated by the voice and voice synthesis processing can be performed using the speech content of the translated voice message and the voice feature data of the selected speaker. Can be converted into the speech content of an English voice message, which can be uttered by the voice of the preferred speaker of the orderer.

As a result, for example, international celebrities such as foreign movie stars and athletes are described on the order receiving side as speakers who can be selected by the ordering party, and the voice feature data of these speakers are held on the order receiving side. Utterance content of Japanese voice messages created by the orderer can be output as voice messages spoken in the language of the country by world-renowned celebrities such as foreign movie stars and sports players, etc. A high voice message can be obtained.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in each of the above-described embodiments, the example in which the voice message using the voice feature data of a specific speaker selected by the orderer 1 is incorporated in the device 5 such as the table clock has been described. In addition to being incorporated in the device 5 or the like, a form recorded on a recording medium 6 such as a CD-ROM may be delivered to the orderer 1, and the created voice message may be sent via the network 3 to the orderer 1. May be downloadable.

In each of the above-described embodiments, the orderer 1 who orders voice messages and the recipient who receives the created voice message are described as the same person. However, the orderer 1 and the recipient who receives the created voice message or The user who uses it may be another person.

In each of the above-described embodiments, the orderer 1 himself / herself inputs the utterance content of the voice message to the order receiving side 2 by key input or the like, but the orderer 1 sends the voice message to the order receiving side 2 by telephone or the like. Tell the utterance content verbally, or send the utterance content of the voice message by facsimile,
The order receiving side 2 may receive it, and the person in charge on the order receiving side 2 may perform key input from a PC or the like prepared on the order receiving side 2.

Further, the present invention creates a processing program in which the processing procedure for realizing the present invention described above is described, and records the processing program on a recording medium such as a floppy (registered trademark) disk, an optical disk, or a hard disk. The present invention also includes a recording medium in which the processing program is recorded. Further, the processing program may be obtained from a network.

As described above, according to the present invention, for example, when an orderer selects a celebrity such as an actor, a singer, a voice actor, or a sports player as a speaker, the utterance content of the voice message designated by the orderer is Only when it is determined that the expression is permitted to be used as the speech content of the speaker, speech synthesis processing is performed using the speech content of the voice message and the voice feature data of the selected speaker. However, since the voice synthesis data is generated, the generated voice synthesis data (voice message) is composed only of expressions permitted to be used as the utterance contents of the speaker. Can prevent issues such as damaging the speaker's honor by letting the speaker speak inappropriate content that is not spoken in public. Service providers to perform the voice data provided services (order side)
However, the common sense as a service provider is no longer suspected.

Whether or not it is composed of expressions permitted to be used as the utterance contents of the speaker, using the permitted expression dictionary in which expressions permitted to be used as the utterance contents of the selected speaker are recorded. Since the determination is made, it is possible to accurately and easily determine whether or not the utterance content of the voice message designated by the orderer is appropriate as the utterance content of the speaker.

In addition, using a network grammar in which an expression permitted to be used as the utterance content of the selected speaker is described, it is determined whether or not the expression is permitted to be used as the utterance content of the speaker. Therefore, it is possible to accurately and easily determine whether or not the utterance content of the voice message designated by the orderer is appropriate as the utterance content of the speaker. In addition,
When network grammar is used, the utterance content of a voice message is limited. However, the appropriateness of the utterance content of the speaker can be increased accordingly, and the speaker can feel secure as a voice right holder. Can do.

In addition, the inappropriate expression dictionary and network grammar are prepared for individual speakers,
It is possible to create the utterance content of a voice message that makes use of the individuality of each speaker.

Further, it has language conversion means for translating the utterance content of the voice message designated by the orderer into another language, and the utterance content of the voice message is translated into the language designated by the orderer by the language conversion means, Since it is possible to perform speech synthesis processing using the utterance content of the translated voice message and the voice feature data of the selected speaker, for example, the utterance content of a Japanese voice message is converted into an English voice message. Utterance content can be converted into the voice of the speaker who likes the orderer.

As a result, for example, international celebrities such as foreign movie stars and athletes are described on the order receiving side as speakers who can be selected by the ordering party, and the voice feature data of these speakers are held on the order receiving side. Utterance content of Japanese voice messages created by the orderer can be output as voice messages spoken in the language of the country by world-renowned celebrities such as foreign movie stars and sports players, etc. A high voice message can be obtained.
