In the present embodiment, the user does not need to specify one content when inputting request information. The request information of this embodiment does not include information for specifying one specific content that is simultaneously handled in the presentation process for the user.

  The presentation form priority determination unit 120 determines the priority of the presentation form of information to be presented to the vehicle side based on the vehicle-side running state acquired by the vehicle information acquisition unit 110. Although not particularly limited, it is preferable that the presentation form determination unit 120 determines that the priority of the presentation form by voice is the highest when the vehicle is running. In addition, when the vehicle is stopped, the presentation form determination unit 120 preferably determines that the priority of the presentation form by text is the highest. When the vehicle is running, the priority of the voice presentation mode is judged to be high, so that information is presented with voice preferentially while driving, so that information can be transmitted without guiding the user's line of sight Can do. Further, when the vehicle is stopped, it is preferable to determine that the priority of the presentation form is the highest by text. When the vehicle is stopped, it is possible to transmit detailed information to the user by presenting the information with text and images. FIG. 2 shows an example of correspondence data in which the priority of the presentation form with respect to the running state of the vehicle referred to by the presentation form priority determination unit 120 in the present embodiment is represented by a numerical value. As shown in FIG. 2, in the present embodiment, when traveling, the voice presentation priority is the highest, the text presentation priority is the second highest, and the image presentation priority is the lowest. Defined. While the vehicle is stopped, it is defined that the text presentation priority is the highest, the image presentation priority is the second highest, and the voice presentation priority is the lowest. The presentation form determination unit 120 of the present embodiment refers to a correspondence relationship between a predetermined traveling state and priority, and presents information presented on the vehicle side based on the acquired traveling state on the vehicle side. Determine the priority. The determination result of the presentation form determination unit 120 is sent to the presentation standby content information generation unit 140.

  The content acquisition unit 130 acquires, from the accessible provider server 300, one or more pieces of content information constituting information according to the vehicle-side request information acquired by the vehicle information acquisition unit 110. The content acquisition unit 130 transmits an information acquisition request to the provider server 300 that provides information based on a URL (Uniform Resource Locator) included in the request information using a predetermined protocol (http or the like). The requested content is received as a response. The content acquisition unit 130 of this embodiment automatically acquires content that can be provided by the provider server 300 specified by the request information before acquiring a presentation command specifying the content from the user. By acquiring all the contents that can be presented in advance, it is possible to shorten the time required from when the user inputs a presentation command that specifies the contents to when the contents are actually presented.

  The content acquisition unit 130 of this embodiment includes a link information acquisition unit 131. When the acquired content includes link information (an address for storing other information related to the content), the link information acquisition unit 131 accesses and associates the address specified based on the link information. Information obtained. Although not particularly limited, when link information is included in the content, the address specified based on the link information is accessed before the presentation command specifying the content is obtained from the user, and the associated information is displayed first. It is preferable to obtain (before receiving a presentation command specifying the content from the user). By acquiring link information in advance before acquiring a presentation command that specifically identifies content from a user on the vehicle side, the time from when the user inputs a presentation command until content is presented, that is, the user The waiting time can be shortened.

  The presentation standby content information generation unit 140 is based on the priority determined by the presentation form determination unit 120 and the presentation form of the content acquired by the content acquisition unit 130 in order from the content of the presentation form with the highest priority of the presentation form. Then, predetermined preprocessing is performed on the content information (including the content specified by the link information included in the content) to generate “presentation standby content information”. The presentation form content information generation unit 140 of the present embodiment preferably generates “presentation standby content information” before acquiring a presentation command specifying the content from the vehicle side. When the presentation form priority determination unit 120 determines that the priority of the presentation form is the order of the voice presentation form, the text presentation form, and the image presentation form, the presentation standby content information generation unit 140 first selects the content to be voice presented. When preprocessing is preferentially performed and preprocessing of all audio presentation content is completed, then preprocessing of content for which text presentation is performed is performed, and finally preprocessing of content for which image presentation is performed is performed. .

  In the case where the content information is in a voice presentation form, that is, the voice information is included in the content acquired by the content acquisition unit 130, and the form of information that is preferentially determined according to the driving state from the vehicle side is the voice. When it is determined that the content is in the presentation form, the presentation standby content information generation unit 140 converts the content information (including the content specified by the link information included in the content) into information presented at the beginning of the content. Presentation standby content information in which a corresponding predetermined cut-out portion is subjected to speech synthesis processing is generated. The predetermined cut-out portion in the present embodiment is a token that is voiced first in the voice information, and the token is a character group or a word group divided into punctuation marks, punctuation marks, and the like.

  The presentation standby content information generation means 140 generates “presentation standby content information” in advance, thereby reducing the time from when the user selects the target content until it is actually presented, that is, the waiting time of the user. can do. In particular, when presenting by speech, speech synthesis processing includes steps such as text segmentation processing (split processing), phonetic processing, and synthetic waveform generation based on the results of phonetic processing, phrase detection, and the relationship between each phrase Analysis, the determination of the prosody of the entire sentence, the phonetic character string processing of the text information for which the prosody has been determined, and the acoustic processing are required. In this embodiment, since the speech synthesis process is performed by cutting out the portion corresponding to the information presented first, the time required from the user's presentation command until the actual voice output is performed, that is, the user's The waiting time can be shortened. In addition, since the information presented next can be processed while the information presented first is output, the sound is output without interruption.

  The presentation content creation means 150 performs predetermined post-processing on the content for which presentation standby content information has been generated by the presentation standby content generation means 140 in response to a presentation command for presenting predetermined content on the vehicle side. Generate presentation content. That is, presentation standby content information that has been pre-processed by the presentation standby content information generation unit 140 is created in advance, and the presentation content creation unit 150 performs predetermined post-processing on the created presentation standby content information, Content for presentation that can be presented by the in-vehicle device 200 on the user side is generated. When the content to be presented is audio information, the presentation standby content information generation unit 140 generates presentation standby content information obtained by voice synthesis of only a cutout portion (token delimited by punctuation marks or punctuation marks) corresponding to the information presented first. Then, the presentation content generation means 150 can synthesize the remaining part other than the first cut-out part (the part corresponding to the information presented by the second and subsequent voices) and present it on the in-vehicle device 200 on the user side (completely ) Generate presentation content. When the presentation content creation unit 150 of the present embodiment receives a presentation command specifying content from the in-vehicle device 200 side, the presentation content creation unit 150 starts creating the content for presentation of the specified content.

  Although not particularly limited, the presentation content creation unit 150 presents content on the vehicle side when it is determined that the vehicle is continuously running for a predetermined time or more based on the vehicle information acquired by the vehicle information acquisition unit 110. It may be assumed that a presentation command to that effect has been accepted, and generation of the presentation content may be started. In this case, the presentation content creation unit 150 generates the presentation content according to the order of priority determined by the presentation form priority determination unit 120. A process for generating presentation content in a form suitable for the state of the vehicle is preferentially executed, and when the provision of the content is completed, a process for generating presentation content in another form is executed.

  The voice synthesizing unit 190 performs voice synthesis processing of the presentation standby content information and voice synthesis processing of the presentation content when the content information is in a voice presentation form. The voice synthesis unit 190 performs voice synthesis processing of the presentation standby content information under the control of the presentation standby content information generation unit 140, and performs voice synthesis processing of the presentation content under the control of the presentation content generation unit 150. Specifically, the speech synthesizer 190 has a language processing unit and an acoustic processing unit (not shown), cuts out (divides) text included in the content according to a predetermined rule, and generates a phonetic sound of a predetermined cut-out part (token). In addition to processing, a synthesized waveform based on the result of phonetic processing is generated to synthesize speech. A voice synthesis processing method for reading out the input text so that the user can hear it is not particularly limited, and a known method can be used at the time of filing. In the present embodiment, the reading and accent of the divided text is determined, the phrase is detected from the connection before and after the words arranged on the text, the relationship between the detected phrases is analyzed, and the sentence is analyzed. The entire prosody is determined, and the text information for which the prosody is determined is expressed as a phonetic character string. The sound processing unit uses the phonetic maintenance time length such as vowel length, consonant length, pause length, etc. from the phonetic character string calculated by the language processing unit, and the basic voice that is a change pattern of the voice A frequency is generated, and voice information including a synthesized waveform based on the frequency is generated. The generated audio information (presentation standby content information, presentation content) can be stored in the storage unit 160.

  The storage unit 160 is generated by the content information acquired by the content acquisition unit 130 and the related information specified by the link information, the presentation standby content information generated by the presentation standby content information generation unit 140, and the presentation content generation unit 150. The presented content is stored so that it can be read out.

  The content output unit 170 sends the presentation standby content information generated by the presentation standby content information generation unit 140 and / or the presentation content generated by the presentation content generation unit 150 to the vehicle side via the transmission / reception unit 180. Output. The presentation content includes audio presentation content, text presentation content, and image presentation content, and is presented to the user via the presentation unit 290 on the in-vehicle device 200 side.

  Next, the in-vehicle device 200 will be described. The in-vehicle device 200 according to the present embodiment includes a microcomputer and its peripheral devices, and sends a content acquisition request, content acquisition, vehicle status, etc. to the information providing device 100 by an operation of a vehicle occupant. Do. As shown in FIG. 1, the in-vehicle device 200 includes a transmission / reception unit 280, a control unit 210, a traveling state detection unit 220, an input unit 230, and a presentation unit 240.

  The transmission / reception means 280 has a communication function 281 and, like the transmission / reception means 180 of the information providing apparatus 100, connects to the network 400 using a specific communication protocol and communicates with other information devices.

  The control unit 210 controls the transmission / reception unit 280, the running state detection unit 220, the input unit 230, and the presentation unit 240. A CPU (Central Processing Unit) of the computer functions as the control unit 210.

  The presentation unit 240 is a presentation device such as a display 291 or a speaker 292, and presents the content acquired from the information providing device 100 to the driver.

  The traveling state detection unit 220 detects a traveling state such as when the vehicle is traveling or the vehicle is stopped, and outputs the detected traveling state to the control unit 210. The method for detecting the driving state is not particularly limited. For example, when the vehicle speed is detected as information indicating the driving state, and the vehicle speed information or the vehicle speed is equal to or higher than a predetermined value, the vehicle is running / the vehicle speed is lower than the predetermined value. The vehicle may detect the result of determining that the vehicle is stopped as a running state, or when side brake on / off information is detected as information indicating the running state and the side brake on / off information or the side brake is on In addition, when the vehicle is stopped / when the side brake is off, the result of determining that the vehicle is traveling may be detected as the traveling state. These detection methods may be used alone, or may be determined by combining a plurality of detection methods. The control unit 210 sends the traveling state detected by the traveling state detection unit 220 via the transmission / reception device 280 to the information providing apparatus 100 side.

  The input means 230 receives an input from a passenger (user) who gets on the vehicle. Information such as an information providing function activation command, information indicating a content specifying command, and other request information are received from the user and output to the control unit 210.

  Next, the provider server 300 that provides third-party content will be described. The provider server 300 is a server having a content source to be provided to a vehicle occupant (user). In response to a request from the user, the content acquisition unit 130 of the information providing apparatus 100 sends a content acquisition request to the provider server 300. The provider server 300 sends content corresponding to this acquisition request to the information providing apparatus 100.

  Based on FIG. 3, the process when the vehicle is traveling will be described. FIG. 3 is a flowchart showing a control procedure of the information providing apparatus 100, the in-vehicle apparatus 200, and the provider server 300.

  First, the in-vehicle device 200 detects the traveling state at a predetermined timing, and sends it to the information providing device 100 via the control unit 210, the transmission / reception unit 280, and the network 400 (S101). The vehicle information acquisition unit 110 of the information providing apparatus 100 acquires the traveling state on the vehicle side. The presentation form priority determination unit 120 determines the traveling state of the vehicle based on the traveling state acquired by the vehicle information acquisition unit 110. When the presentation form priority determination unit 120 determines that the vehicle is traveling (Y in S201), the processing after S202 is performed. On the other hand, when it is determined that the vehicle is stopped, the processing after S251 shown in FIG. 7 is performed.

  The in-vehicle device 200 transmits a request including the server information of the content provider server 300 to the information providing device 100 (S102), and the information providing device 100 acquires the request information. The request information in this process is an information processing function activation command for the information providing apparatus 100. The server information included in the request information includes, for example, the IP address, domain name, port number, resource path, and scheme type of the provider server 300. The request information of the present embodiment does not include information that specifically identifies one content that the user desires to provide. The request information may be sent to the information providing apparatus 100 together with the traveling state.

  Based on the server information of the provider server 300 included in the acquired request information, the information providing apparatus 100 requests the provider server 300 to provide information (S202). Upon receiving the request from the information providing apparatus 100, the provider server 300 transmits a list of a plurality of content names corresponding to the request to the center as a response (S301). The information providing apparatus 100 converts the acquired information into a form (size, presentation position, data format, etc.) suitable for the in-vehicle apparatus 200, and then sends the content list to the in-vehicle apparatus 200. The in-vehicle device 200 presents a content list to the user (S103). FIG. 5 is a diagram illustrating a screen image of information presented on the traveling in-vehicle device 200. In step S103, the in-vehicle device 200 presents a content list L in a list format to the user. This content list enumerates the content names that constitute the information corresponding to the request information acquired from the user and includes URLs of information on those contents. Link information is included in list item A and list item B shown in the content list.

  The content acquisition unit 130 automatically acquires content from the provider server 300 without waiting for acquisition of a presentation command specifying the content from the user whose content list L is presented (S302, S204).

  When the acquired content includes link information (Y in S206), the link information acquisition unit 131 of the content acquisition unit specifies based on the link information before acquiring the presentation command specifying the content from the vehicle side. The associated address is accessed and the associated information is acquired from the content server 300 (S207, S303, S208).

  The presentation standby content information generation unit 140 recognizes the content presentation form. This flow is a process while the vehicle is traveling. In the present embodiment, since the voice presentation form has the highest priority while traveling, it is determined whether or not the acquired content is a target of voice presentation (S209). ). When the acquired content is the target of voice presentation (Y in S209), presentation standby content information in which a predetermined cut-out portion corresponding to information presented at the beginning of the content is subjected to voice synthesis processing based on the content information Is generated (S210). Among the list items A to D of the content list L shown in FIG. 5, the list items A and B can be presented as audio. The contents Q1 and Q2 that are the contents of the list items A and B are acquired in S208. The presentation standby content information generation unit 140 cuts out audio information (first token) presented first from information included in the content. In this example, a punctuation mark is used as a division symbol for cutting out a token from a character string. From Q1 of list item A, “This is text for reading aloud.”, Cut out from Q2 of list item B, “Sample text. . " In this example, a punctuation mark is used as a division symbol, but the type of division symbol is not limited. The voice synthesizer 190 performs a voice synthesis process on the first token that has been cut out. The method of speech synthesis processing is not particularly limited, but an example of the processing procedure is shown in FIG. As shown in FIG. 6, after the start (S501), the input of the text to be synthesized is accepted, the text is divided by a predetermined division symbol (punctuation mark, punctuation mark, etc.) (S503), and the token presented first Is cut out (S504). A voice synthesis process is performed on the first token that is cut out (S505), and the processed voice data is stored in the storage unit 160 (S506).

  Returning to the flow of FIG. The presentation standby content information generation unit 140 stores the generated presentation standby content (content in which the first token is voice-synthesized) in the storage unit 160 (S211). This pre-processing, that is, generation of presentation standby content information is repeated for all the contents that can be presented by voice (S212). When the generation of the presentation standby content information for all the contents that can be presented by voice is completed, a presentation command specifying the content is waited from the in-vehicle device. In this way, by creating the presentation standby content information in advance, it is possible to perform speech synthesis processing of the token that has been cut out second while the first token is being output, so that the audio output is presented. Voice output (presentation) can be performed immediately after the command. In addition, by generating presentation standby content information for all contents that can be presented by voice, voice output can be immediately executed regardless of which content is specified by the user. The processing required for audio output takes time, but according to the present embodiment, since the synthesis process of the audio presented first is completed before the user inputs the presentation command specifying the content, The voice output can be performed immediately after receiving the presentation command.

  When the presentation command specifying the content is acquired from the in-vehicle device 200 (S104), the content to be presented is specified based on the presentation command (S213). The presentation content generation unit 150 performs speech synthesis processing on portions other than the cutout portion corresponding to the information presented first in the content specified by the presentation command (finally all speech synthesis processing has been performed). ) A content for presentation is generated (S214). The speech synthesis process is the same as the processing method for the presentation standby content. Basically, the processing procedure is the same as that shown in FIG. 6, but in step S504, the tokens are cut out in order from the second token to the last token, and speech synthesis processing is performed for each token. The generated presentation content is stored in the storage unit 160 as necessary (S215). The generated presentation standby content information and / or presentation content is sent to the in-vehicle device 200 (S216), and the presentation unit 240 of the in-vehicle device 200 presents (outputs) the acquired presentation content. The presentation standby content information specified in S213 is preferably sent to the in-vehicle device 200 without waiting for the completion of the generation of the presentation content. As a result, the processing time can be further shortened.

  In this example, the acquisition of the presentation command specifying the content from the in-vehicle device 200 is used as a trigger for starting the process of generating the content for presentation. However, the vehicle continues to be in a running state for a predetermined time or more based on the acquired vehicle information. If it is determined that there is, the generation of the presentation content may be started. An example of this processing is shown in FIG. As shown in FIG. 4, after the generation / storage (S210, S211) of the presentation standby content information (or after the transmission (S203) / presentation (S103) of the content list shown in FIG. 3), the acquired vehicle information If the vehicle has been continuously running for a predetermined time or longer based on the above (Y in S230), the speech synthesis processing of the parts other than the first presentation part of all contents is executed (generation of presentation contents) (S231) )I do. If the presentation command specifying the content is received from the in-vehicle device 200 during the predetermined time, the process proceeds to S213 in FIG. The generated presentation content is stored in the storage unit 160 and waits for reception of a presentation command specifying the content from the in-vehicle device 200. When the presentation command is received (S134), the content is specified (S234), and the audio signal of the presentation content generated in advance is sent to the in-vehicle device 200 (S235). Thereafter, the same processing as S217 and the subsequent steps in FIG. 3 is performed.

  Returning to FIG. 3, when transmission of the audio signal constituting the content is completed (S217), text content with the next highest priority is generated during traveling (S218). When the generation of the text content is completed, an image content with the third highest priority is generated during traveling. The generated text content and image content are stored in the storage unit 160 as necessary.

  The in-vehicle device 200 waits for the detection timing of the running state (S107), acquires the running state when the detection timing comes (S108), and sends it to the waiting information providing device 100 (S101, proceeds to S151 in FIG. 7). ). The in-vehicle device 200 may switch the presentation form according to a change in the running state when all of the content presented by voice, the content presented by text, and the content presented by an image are acquired. In the flowchart of FIG. 3, in order to make the processing flow easy to understand, a change in the driving state is determined when the contents of all presentation forms are prepared, but the case where the driving state is switched during content transmission. However, the change in the running state of the vehicle may be constantly monitored so that the content to be provided can be switched as appropriate.

  As described above, according to the present embodiment, while presenting by voice during traveling, content that may be presented without waiting for a presentation command for specific content from the user when presenting by voice is displayed. Since the presentation waiting content information obtained by the first token and subjected to the speech synthesis process is generated in advance, even if the voice presentation requiring multi-step processing is prioritized, the process from the presentation command to the voice presentation is performed. It is possible to shorten the time and provide an information providing apparatus with excellent responsiveness.

  FIG. 7 is a flowchart showing a control procedure when the vehicle is stopped. The processing until the driving state and request information are transmitted from the in-vehicle device 200 (S101, 102) and the content list is presented is the same as the processing shown in FIG.

  When the presentation command specifying the content is acquired from the in-vehicle device 200, the content is specified (S256), and the specified content is requested to the provider server 300 (S257). The content is provided from the provider server (S352). This process is a process in which the vehicle is stopped. When the vehicle is stopped, the text presentation has the highest priority, the image presentation has the second highest priority, and the text presentation has the third highest priority. The information generation means 140 and the presentation content generation means 150 cooperate to generate presentation content that can be presented by the in-vehicle device 200 (S258), and transmit it to the in-vehicle device 200 (S259).

  When transmission of text content and image content is completed and there is content presented by voice, that is, when there is target information for speech synthesis (Y in S260), the presentation standby content information generation unit 140 of the information providing apparatus 100 Speech synthesis of the token presented first is performed (S261). This process of generating presentation standby content information is automatically performed without waiting for a request for presentation of audio content from the in-vehicle device 200.

  When presentation of specific content presented by voice is requested from the in-vehicle device 200 (S156), the content is identified (S262), and the presentation content generation means 150 performs speech synthesis processing for portions other than the first presentation portion. Execute (S263). The audio signal of the content in a form capable of outputting audio in the in-vehicle device 200 is sent to the in-vehicle device 200 (S264). The in-vehicle device 200 presents the received audio signal as audio by the presentation means 240 (speaker) (S157). When the transmission process of the audio signal is completed (Y in S265), it waits for acquisition of the running state (S266). Parts common to the processing shown in FIG. 3 are omitted to avoid duplication.

  As described above, when the vehicle is stopped, the text presentation and the image presentation are preferentially executed, so that the user can confirm detailed information when the vehicle is stopped.

  The embodiment described above is described for facilitating the understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
