[0036] Figure 1 is a block diagram showing a configuration of an apparatus for controlling a vehicle message output according to an embodiment of the present invention.

[0037] like Figure 1 As shown, the device 100 for controlling vehicle message output may include an input device 110 , a position acquisition device 120 , an output device 130 , a memory 140 , and a processor 150 .

[0038] The input device 110 may receive an input corresponding to a user's touch, action (gesture) or voice, and send the received input to the processor 150. The processor 150 may control the operation of a device for controlling the output of a vehicle message corresponding to the information input by the user. According to an embodiment, the input device 110 may include at least one of a touch input device having directionality (+ (increase) and - (decrease)), a mechanical input device, or a combination thereof. For example, the input device 110 may be arranged in an area of ​​the steering wheel, and may be implemented so that the user can manipulate the input device 110 with a finger while holding the steering wheel. The input device 110 may be implemented as a roller, a button, a touch screen, a touchpad, a trackball, etc. that can be manipulated by the user. As another example, the input device 110 may be implemented using at least one of a motion sensor for detecting the driver's action (gesture), a voice recognition sensor for detecting voice, or a combination thereof.

[0039] The position acquisition device 120 can be equipped with a GPS receiving device to acquire vehicle position information and map match the vehicle's position with pre-stored map data to provide a map image including road information of a specific area based on the vehicle's position and provide a route from the current position to the destination set by the driver.

[0040] The output device 130 may output an image or sound under the control of the processor 150. According to the embodiment, the output device 130 may be implemented as a display device or a sound output device. In this case, the display device may include a HUD, a combined instrument panel, etc., and the sound output device may include a speaker.

[0041] The memory 140 may store at least one algorithm that executes the operation or execution of various instructions for the operation of the device for controlling the vehicle message output according to an embodiment of the present invention. According to the embodiment, the memory 140 may store at least one instruction executed by the processor 150, and the instruction may cause the device for controlling the device of the present invention to operate. The memory 140 may include at least one storage medium selected from a flash memory, a hard disk, a memory card, a read-only memory (ROM), a random access memory (RAM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk.

[0042] The processor 150 may be implemented with various processing devices embedded with a semiconductor chip capable of executing or executing various instructions, and may control the operation of the device for controlling the output of vehicle messages according to an embodiment of the present invention. The processor 150 may be electrically connected to the input device 110, the position acquisition device 120, the output device 130, and the memory 140 through a wired cable or various circuits to transmit electrical signals including control instructions, etc., and may perform operations or data processing for control and / or communication. The processor 150 may include at least one of a central processing unit, an application processor, a communication processor (CP), or a combination thereof.

[0043] The processor 150 may generate a guidance message. In this case, the guidance message may include information for guiding the vehicle to the destination along the set route, road information included in the route, and a message corresponding to the accident information. In addition, the guidance message may include a message corresponding to a response to a user command, and may include a message corresponding to vehicle status information that changes according to user operations. In addition, the guidance message may include news, weather, and a message corresponding to the content of a mobile phone message. According to an embodiment, the processor 150 may generate a guidance message as a text sentence decomposed into phoneme units.

[0044] The processor 150 can determine whether the user has set a summary of the guidance message. When it is determined that the user has set a summary of the guidance message, the processor 150 can omit the postposition (subject marker or object marker) or predicate in the guidance message so that only the necessary content is delivered to the user, and summarize the guidance message by replacing it with a short word with the same meaning. For example, when "Turn left later" is generated as a guidance message, the processor 150 can summarize the guidance message as "Turn left immediately". As another example, when "Later, take the third lane and drive to the side of the underpass" is generated as a guidance message, the processor 150 can summarize the guidance message as "Take the third lane and drive to the road next to the underpass".

[0045] When the user sets the summary of the guide message, the processor 150 can summarize the guide message and then generate an audio sound source obtained by synthesizing the summarized guide message into an audible voice message by a voice synthesizer. Meanwhile, when the user does not set the summary of the guide message, the processor 150 can generate an audio sound source obtained by synthesizing the guide message into a voice message.

[0046] When the audio sound source obtained by synthesizing the guide message is generated, the processor 150 may determine whether the user sets a speech speed change of the guide message.

[0047] When it is determined that the speech speed change of the guide message is not set, the processor 150 may control the audio sound source obtained by synthesizing the guide message into the voice message to be output as it is.

[0048] Meanwhile, when it is determined that the user has set a change in the speech speed of the guidance message, the processor 150 may determine whether there are keywords in the guidance message. In this case, the keywords may include at least one of a place name, a person's name, driving direction information, traffic law related information, or a combination thereof. For example, traffic law related information may include road speed limit information, average speed information in an interval control interval, child / elderly protection area information, accident-prone area information, etc.

[0049] When it is determined that there is no keyword in the guide message, the processor 150 may set a speech rate and convert all sound sources of the guide message at the set speech rate.

[0050] According to an embodiment, when it is determined that there is no keyword in the guidance message, the processor 150 may determine whether the number of times the same guidance message is generated is greater than or equal to a specified number of times. In addition, the processor 150 may determine whether the guidance message includes a response content to a user command.

[0051] According to the embodiment, the processor 150 may count the number of times the same guidance message is generated, and determine whether the cumulative count number is greater than or equal to the specified number of times. In addition, when a user command is input before the guidance message is generated, the processor 150 may determine that the guidance message includes the response content to the user command. For example, when a guidance message such as "Please say it again", "Turn on the air conditioner", etc. is generated, the processor 150 may determine that the response content to the user command is included.

[0052] When it is determined that the number of times the same guidance message is generated is greater than or equal to the specified number of times, the processor 150 may apply the specified speech speed to the guidance message. In addition, when the guidance message includes response content to the user command, the processor 150 may apply the specified speech speed to the guidance message. In this case, the specified speech speed may be set to 1.1 to 1.2 times the preset speed. The processor 150 may convert all sound sources of the guidance message at the specified speech speed.

[0053] Meanwhile, when it is determined that the keyword exists in the guide message, the processor 150 may determine whether the user has set an emphasis scheme for emphasizing the keyword.

[0054] When it is determined that the user has not set an emphasis scheme for emphasizing the keyword, the processor 150 may set a speech rate for all sound sources of the guide message and output the guide message at the set speech rate.

[0055] Meanwhile, when it is determined that the user has set an emphasis scheme for emphasizing keywords, the processor 150 may extract the time information of the portion where the keywords are spoken. According to the embodiment, the processor 150 may classify the portion where the guide message is spoken into a first portion and a second portion other than the first portion, wherein the first portion is at least one portion where the keywords are spoken. In addition, the time information of the first portion may be extracted. According to the embodiment, the processor 150 may extract the time information of the first portion based on the time alignment information of the phoneme unit output from the speech synthesizer. For example, when "Turn left later in the direction of Sang-il IC" is generated as the guide message, the processor 150 may extract the time information of the first portion as 0.13 seconds to 0.22 seconds and 0.41 seconds to 0.55 seconds.

[0056] When extracting the time information of the first part, the processor 150 may apply the emphasis scheme to the first part.

[0057] According to the embodiment, when the speech rate is controlled in the emphasis scheme set by the user, the processor 150 may control the first part and the second part to be output at different speeds. According to the embodiment, the processor 150 may control the first part to be converted at a specified speed, and may control the second part to be converted at a higher speech rate than the first part. In this case, the specified speed may be set to a preset speed or a higher speed at which the guidance message is spoken. For example, when "Turn left later" is generated as a guidance message, the processor 150 may control "Turn left" to be converted at a specified speed, and control "later" to be converted at a speed higher than the specified speed. When "Speed ​​bumps appear continuously ahead" is generated as a guidance message, the processor 150 may control "Speed ​​bumps" to be converted at a specified speed, and control "ahead, continuously" to be converted at a speed higher than the specified speed. When the processor 150 generates "Later, take the third lane, drive along the road next to the underpass" as a guidance message, the processor 150 may control "Third lane, road next to the underpass" to be converted at a specified speed, and control "Later, go, drive" to be converted at a speed higher than the specified speed.

[0058] According to the embodiment, when the emphasis scheme set by the user is to repeat the speech, the processor 150 can convert the guidance message so that the first part is repeated a preset number of times. According to the embodiment, the processor 150 can convert the first part to be repeated twice. For example, when "Turn left later" is generated as the guidance message, the processor 150 can convert "Turn left" to "Turn left later, turn left" so that "Turn left" is repeated twice. As another example, when the processor 150 generates "Later, take the third lane and drive along the road next to the underpass" as the guidance message, the processor 150 can convert it to "Take the third lane, the third lane, and then go to the road next to the underpass".

[0059] According to an embodiment, when the emphasis scheme set by the user is pitch control, the processor 150 may control the sound source of the first part to be replaced with the sound source after adjusting the pitch and output. According to an embodiment, the processor 150 may generate the sound source after adjusting the pitch by using a pitch conversion algorithm.

[0060] The processor 150 may control the guide message to which the emphasis scheme is applied to the first portion to be output through the output device 130 .

[0061] According to an embodiment of the present invention, after outputting the guide message, the processor 150 may determine whether there is a user's request to re-speak. When it is determined that there is a user's request to re-speak, the processor 150 may further summarize the output guide message. For example, after outputting the guide message "I will inform you of the main news of the current time" through the output device 130, when it is determined that there is a user's request to re-speak, the processor 150 may summarize the guide message as "I will inform you of the current news". In addition, the processor 150 may control the output device 130 to re-output the additional summarized guide message.

[0062] According to another embodiment of the present invention, when outputting the guide message, the processor 150 may determine whether there is a user input for changing the output setting information. According to the embodiment, when outputting the guide message through the output device 130, if it is determined that there is a user input for changing the output setting information, the processor 150 may control the output of the guide message by applying the changed output setting information corresponding to the user input.

[0063] For example, when the guide message is output through the output device 130, if there is a user input for preventing the guide message from being received, the processor 150 may stop outputting the guide message through the output device 130. In addition, when there is a user input for adjusting the volume of the output guide message, the processor 150 may control the volume to be adjusted and output. In addition, when there is a user input for adjusting the speech speed of the guide message, the processor 150 may control the speech speed to be adjusted and output.

[0064] In this case, the user input may include an input corresponding to a user's touch, action (gesture), or voice. Therefore, when outputting a guide message, the processor 150 may change the output setting information of the guide message using only a simple input from the user to change the output setting information, thereby improving user convenience.

[0065] According to an embodiment, when the processor 150 plans to output a designated guide message and a user changes output setting information for the designated guide message, the processor 150 may determine whether the number of times the output setting information is changed for the designated guide message exceeds a threshold number of times.

[0066] When it is determined that the user has changed the output setting information for a specified guide message, and the number of times the output setting information for the specified guide message has been changed exceeds a threshold number, the processor 150 may output a message in the form of an image for confirming whether to apply the output setting information changed when outputting the specified guide message.

[0067] The processor 150 may determine whether the user has selected the output setting information that the application changes when outputting the specified guide message. When it is determined that the user has selected the output setting information that the application changes when outputting the specified guide message, the processor 150 may control the output of the specified guide message by applying the output setting information that changes when outputting the specified guide message.

[0068] When it is determined that the user has not applied the output setting information changed when the designated guide message is output, the processor 150 may determine whether to change the output setting information by determining whether there is a user input for changing the output setting information.

[0069] Figures 2 to 6 is a schematic diagram illustrating a method of controlling a vehicle message output according to an embodiment of the present invention.

[0070] like Figure 2 As shown, in step S110, the processor 150 may generate a guidance message. In this case, the guidance message may include information for guiding the vehicle to the destination along the set route, road information included in the route, and a message corresponding to the accident information. In addition, the guidance message may include a message corresponding to a response to a user command, and may include a message corresponding to vehicle status information that changes according to user operations. In addition, the guidance message may include news, weather, and messages corresponding to mobile phone message content. According to an embodiment, the processor 150 may generate a guidance message as a text sentence decomposed into phoneme units.

[0071] In step S120 , the processor 150 may determine whether the user has set a guide message summary.

[0072] When it is determined in step S120 that the user has set a summary of the guidance message, in step S130, the processor 150 may omit the postposition (subject marker or object marker) or predicate in the guidance message so that only the necessary content is delivered to the user, and summarize the guidance message by replacing it with a short word with the same meaning. For example, when "Turn left later" is generated as the guidance message, the processor 150 may summarize the guidance message as "Turn left immediately". As another example, when "Later, take the third lane and drive to the side of the underpass" is generated as the guidance message, the processor 150 may summarize the guidance message as "Take the third lane and drive to the road next to the underpass".

[0073] When the user sets the summary of the guide message, in step S140, the processor 150 may summarize the guide message and then generate an audio sound source obtained by synthesizing the summarized guide message into an audible voice message by a voice synthesizer. Meanwhile, when the user does not set the summary of the guide message, the processor 150 may generate an audio sound source obtained by synthesizing the guide message into a voice message.

[0074] In step S150, when the audio sound source obtained by synthesizing the guide message is generated, the processor 150 may determine whether the user sets a speech speed change of the guide message.

[0075] When it is determined in step S150 that the speech rate change of the guide message is not set, the processor 150 may control the audio sound source obtained by synthesizing the guide message into the voice message to be output as it is.

[0076] Meanwhile, when it is determined that the user has set a change in the speech speed of the guidance message, in step S160, the processor 150 may determine whether there are keywords in the guidance message. In this case, the keywords may include at least one of a place name, a person's name, driving direction information, traffic law related information, or a combination thereof. For example, traffic law related information may include road speed limit information, average speed information in an interval control interval, child / elderly protection area information, accident-prone area information, etc.

[0077] When it is determined in step S160 that there are no keywords in the guidance message, in step S180, the processor 150 may set the speech rate and convert all sound sources of the guidance message at the set speech rate. Figure 3 Describes the situation where the keyword does not exist.

[0078] Meanwhile, when it is determined in step S160 that the keyword exists in the guide message, in step S170 , the processor 150 may determine whether the user has set an emphasis scheme for emphasizing the keyword.

[0079] When it is determined in step S170 that the user has not set an emphasis scheme for emphasizing the keyword, in step S180, the processor 150 may set a speech rate for all sound sources of the guide message and convert all sound sources of the guide message at the set speech rate.

[0080] Meanwhile, when it is determined in step S170 that the user has set an emphasis scheme for emphasizing keywords, in step S190, the processor 150 may extract the time information of the portion in which the keywords are spoken. According to an embodiment, the processor 150 may classify the portion in which the guide message is spoken into a first portion and a second portion other than the first portion, wherein the first portion is at least one portion in which the keywords are spoken. In addition, the time information of the first portion may be extracted. According to an embodiment, the processor 150 may extract the time information of the first portion based on the phoneme unit time alignment information output from the speech synthesizer. For example, when "Turn left later in the direction of Sang-il IC" is generated as a guide message, the processor 150 may extract the time information of the first portion as 0.13 seconds to 0.22 seconds and 0.41 seconds to 0.55 seconds.

[0081] When the time information of the first part is extracted, the processor 150 may apply an emphasis scheme to the first part in step S200.

[0082] According to the embodiment, in step S200, when the speech rate is controlled in the emphasis scheme set by the user, the processor 150 may control the first part and the second part to be output at different speeds. According to the embodiment, the processor 150 may control the first part to be converted at a specified speed, and may control the second part to be converted at a higher speech rate than the first part. In this case, the specified speed may be set to a preset speed or a higher speed at which the guidance message is spoken. For example, when "Turn left later" is generated as a guidance message, the processor 150 may control "Turn left" to be converted at a specified speed, and control "later" to be converted at a speed higher than the specified speed. When "Speed ​​bumps appear continuously ahead" is generated as a guidance message, the processor 150 may control "Speed ​​bumps" to be converted at a specified speed, and control "Ahead, continuously" to be converted at a speed higher than the specified speed. When the processor 150 generates "Later, take the third lane, drive along the road next to the underpass" as the guidance message, the processor 150 can control "Third lane, road next to the underpass" to convert at a specified speed, and control "Later, go, drive" to convert at a speed higher than the specified speed.

[0083] According to the embodiment, in step S200, when the emphasis scheme set by the user is to repeat the speech, the processor 150 may convert the guidance message so that the first part is repeated a preset number of times. According to the embodiment, the processor 150 may convert the first part to be repeated twice. For example, when "Turn left later" is generated as the guidance message, the processor 150 may convert "Turn left" to "Turn left later, turn left" so that "Turn left" is repeated twice. As another example, when the processor 150 generates "Later, take the third lane and drive along the road next to the underpass" as the guidance message, the processor 150 may convert it to "Take the third lane, the third lane, and then go to the road next to the underpass".

[0084] According to an embodiment, in step S200, when the emphasis scheme set by the user is tone control, the processor 150 may control the sound source of the first part to be replaced with the sound source after adjusting the tone and output. According to an embodiment, the processor 150 may generate the sound source after adjusting the tone by using a tone conversion algorithm.

[0085] In step S210 , the processor 150 may control outputting a guide message to which the emphasis scheme is applied to the first portion through the output device 130 .

[0086] like Figure 3 As shown, when it is determined in step S160 that there is no keyword in the guidance message, in step S161, the processor 150 can determine whether the number of times the same guidance message is generated is greater than or equal to a specified number of times. In addition, in step S162, the processor 150 can determine whether the guidance message includes a response content to the user command.

[0087] According to the embodiment, in step S161, the processor 150 may count the number of times the same guidance message is generated, and determine whether the cumulative count number is greater than or equal to the specified number of times. In addition, in step S162, when a user command is input before the guidance message is generated, the processor 150 may determine that the guidance message includes a response content to the user command. For example, when a guidance message such as "Please say it again", "Turn on the air conditioner", etc. is generated, the processor 150 may determine that the response content to the user command is included.

[0088] When it is determined in step S161 that the number of times the same guidance message is generated is greater than or equal to the specified number of times, the processor 150 may apply the specified speech rate to the guidance message. In addition, when the guidance message includes the response content to the user command in step S162, the processor 150 may apply the specified speech rate to the guidance message in S163. In this case, the specified speech rate may be set to 1.1 to 1.2 times the preset speed. In step S180, the processor 150 may convert all sound sources of the guidance message at the specified speech rate.

[0089] like Figure 4 As shown, after the guide message is output in step S310, the processor 150 may determine whether there is a user's re-speaking request in step S320.

[0090] When it is determined in step S320 that there is a user's re-speaking request, in step S330 , the processor 150 may further summarize the output guide message.

[0091] For example, after outputting the guide message "I will inform you of the main news of the current time" through the output device 130, when it is determined that there is a user's request to re-speak, in step S340, the processor 150 may summarize the guide message as "I will inform you of the current news". In addition, in step S350, the processor 150 may control the output device 130 to re-output the additional summarized guide message.

[0092] like Figure 5 As shown, when the guide message is output in step S410, in step S420, the processor 150 may determine whether there is a user input for changing the output setting information. According to an embodiment, when the guide message is output through the output device 130, if it is determined that there is a user input for changing the output setting information, in step S430, the processor 150 may control the output of the guide message by applying the changed output setting information corresponding to the user input.

[0093] For example, when the guidance message is output through the output device 130, if there is a user input for preventing the guidance message from being received, in step S430, the processor 150 may stop outputting the guidance message through the output device 130. In addition, when there is a user input for adjusting the volume of the output guidance message, in step S430, the processor 150 may control the volume to be adjusted and output. In addition, when there is a user input for adjusting the speech speed of the guidance message in step S420, the processor 150 may control the speech speed to be adjusted and output in step S430.

[0094] In this case, the user input may include an input corresponding to a user's touch, action (gesture), or voice. Therefore, when outputting a guide message, the processor 150 may change the output setting information of the guide message using only a simple input from the user to change the output setting information, thereby improving user convenience.

[0095] like Figure 6As shown, when the processor 150 plans to output a designated guide message and the user changes output setting information for the designated guide message in step S510, the processor 150 may determine whether the number of times the output setting information for the designated guide message is changed exceeds a threshold number in step S520.

[0096] When it is determined that the user has changed the output setting information for a specified guide message, and the number of times the output setting information for the specified guide message has been changed exceeds a threshold number, the processor 150 may output a message in the form of an image for confirming whether to apply the output setting information changed when outputting the specified guide message.

[0097] In step S530, the processor 150 may determine whether the user selects output setting information that the application changes when outputting a designated guide message.

[0098] When it is determined in step S530 that the user selects to apply the output setting information that changes when outputting the designated guide message, in step S540, the processor 150 may control the output of the designated guide message by applying the output setting information that changes when outputting the designated guide message.

[0099] When it is determined in step S530 that the user has not applied the output setting information changed when the designated guide message is output, the processor 150 may perform step S420 to determine whether the output setting information is changed.
