Description

Electronic device and message playing method

Technical Field

The present invention relates to an electronic device having a voice playing function of a message, and more particularly, to a voice playing function of a message suitable for an in-vehicle environment.

Background

In recent years, social Networking Services (SNS) have been increasingly used to transmit, share, and spread information between users of smart phones and personal computers via the internet. In SNS, information transmitted by a user is transmitted to other users via messages, emails, or the like as media, and the other users reply to the received messages or the like, or further, spread the information to different users. Regarding the transmission and reception of such a message or the like, for example, patent document 1 discloses a terminal device that notifies the content of the message by voice by reading the text of the received message.

Problems to be solved by the invention

One of applications that can be installed in a smart phone, a car-mounted device, or the like is a WeChat. If the WeChat is mounted on the in-vehicle device, the user can chat with other users via messages using the WeChat while traveling. If the message is received, the message is displayed on the display, but if the driver's line of sight is directed toward the display during traveling, the driver may not notice the front, and safe driving may be hindered. In the vehicle-mounted WeChat, not only the received message is displayed, but also the received message is played in voice to notify the driver of the content.

In the case of voice playing a received message, first, voice playing is performed on the user name of the sender, and then, voice playing is performed on the body of the message. An example of voice playback of a message is shown in fig. 1. The figure shows an example of the transmission and reception of messages when a plurality of users in a group chat. For example, when the user name "universe super-invincible kitten" transmits "good" for a received message, the vehicle-mounted WeChat initially plays the voice of the "universe super-invincible kitten" as the user name, and then plays the voice of the "good" as the body.

However, the user name of the sender is often long, and the voice playback of such a user name takes extra time. If the number of received messages is large, the user may feel uncomfortable when the voice play of the user name is long, and particularly when the content of the message body is short. Further, in the case of a message having importance or urgency, if the user name is long, it takes time before the text is played, which may cause a problem to the user.

The present invention solves such conventional problems, and an object thereof is to provide an electronic device and a playback method capable of efficiently playing back a received message.

Means for solving the problems

The electronic device according to the present invention has a function of playing a message in voice, and includes: a receiving unit that receives a message via wireless communication; a playing unit for performing voice playing on the user name and the message text of the sender contained in the message received by the receiving unit; a detection unit that detects the length of a user name included in a message; and a control unit for controlling the playing unit based on the detection result, wherein the control unit enables the playing unit to play the simplified user name under the condition that the length of the user name is more than a certain length.

In one embodiment, the control unit simplifies the user name so as to be distinguishable from other user names. In one embodiment, the control unit performs a morpheme analysis on the user name, and simplifies the user name by using a word extracted based on the analysis result. In one embodiment, the control unit simplifies the user name in such a way that the subject is extracted and the modifier is deleted. In one embodiment, the control unit retains a modifier and simplifies the modifier when the extracted subject is included in another user name. In an embodiment, the control unit simplifies the user name in such a way that the first character and the name of the modifier are extracted from the user name. In one embodiment, the control means simplifies the user name so as to delete the character with low frequency of use included in the user name. In an embodiment, the control unit simplifies the user name after the 2 nd time except for the case of playing the user name for the first time. In one embodiment, the control unit simplifies the user name when the length of the user name is equal to or greater than a predetermined value and the length of the message body is equal to or greater than a predetermined value.

The present invention relates to a method for playing a message in an electronic device including a receiving unit, a wireless communication unit, a playing unit and a control unit, comprising: a step of receiving a message by the receiving unit via the wireless communication unit; a step of determining, by the control unit, whether or not the length of the user name of the sender included in the received message is equal to or longer than a predetermined value; a step of simplifying the user name by the control unit when the length of the user name is equal to or longer than a predetermined value; and playing the simplified user name and the simplified message text by the playing unit under the condition that the length of the user name is more than a certain length.

Effects of the invention

According to the invention, when the received message is played in voice, when the length of the user name is more than a certain value, the simplified user name is played in voice, so that the efficiency of playing voice of the message can be improved, and the convenience of users can be improved.

Detailed Description

Fig. 2 is a diagram showing a configuration example of an information system according to an embodiment of the present invention. As shown in the figure, the information system 10 of the present embodiment includes, for example: an electronic device 20 exemplified by a personal computer 20A, a smart phone 20B, an in-vehicle device 20C, and the like, and a server 40 wirelessly connected to the electronic device 20 via a network 30. Here, 1 server and 3 electronic devices are illustrated, but a plurality of servers or a plurality of electronic devices can be connected to the network 30.

The network 30 includes various connections such as an intranet, the internet, a Local Area Network (LAN), and a public wireless line network such as 4G/5G, and short-range wireless communication, and can perform data communication between the electronic device 20 and the server 40 by wireless. The electronic device 20 can be a client connected to the server 40 via a network, and can use various information or services provided by the server 40. In 1 preferred embodiment, the information system 10 functions as a message system for transmitting, sharing, diffusing, etc. information among users.

Examples (example)

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, as an electronic device having a function of transmitting and receiving a message, the in-vehicle device 20C shown in fig. 2 is exemplified. In the in-vehicle apparatus, for example, an application program such as a WeChat is installed, and the application program is used to exchange messages between users.

Fig. 3 is a block diagram showing an internal configuration of the in-vehicle apparatus 100 according to the embodiment of the present invention. The in-vehicle device 100 includes an input unit 110, a position detection unit 120, a navigation unit 130, a communication unit 140, a display unit 150, a voice output unit 160, a storage unit 170, and a control unit 180. However, the configuration shown here is an example, and the in-vehicle apparatus 100 may include other functions, such as an audio/video function, a television/radio broadcast receiving function, and the like.

The input unit 110 includes an input key device, a voice input recognition apparatus, a touch panel, a camera, and the like, and receives instructions from a user via these devices and supplies the instructions to the control unit 180. The in-vehicle apparatus 100 according to the present embodiment has a function of transmitting and receiving a message, as will be described later, and a user can create a message using a key device or voice input.

The position detecting unit 120 detects the current position using a GPS signal and/or detects the current position using an azimuth sensor such as a gyro sensor. The navigation unit 130 displays, for example, a road map around the current location of the host vehicle detected by the position detection unit 120 on the display unit 150, or searches for a route from the current location to the destination, and displays the searched route on the road map to guide the host vehicle to the destination. When the in-vehicle apparatus 100 holds the road map database, the navigation unit 130 displays the road map or searches for a route to the destination. When the in-vehicle apparatus 100 does not hold the road map database, as shown in fig. 2, a road map server is accessed via the network 30, and necessary information including road map data is acquired from the road map server.

As shown in fig. 2, the communication unit 140 can perform data communication with the server 40 or another electronic device by wireless. The communication unit 140 may be a communication module that integrally includes a public wireless network such as 4G/5G, a GPS receiving function, a near field communication function, and the like, and may be a TCU (remote information control unit), for example. The communication unit 140 may use a communication function built in the in-vehicle apparatus 100, or may use a communication function of an electronic device (for example, a smart phone 100A) connected to the in-vehicle apparatus 100 as shown in fig. 4.

In one embodiment, when the smart phone 100A is connected to the in-vehicle device 100, the in-vehicle device 100 operates in a specific mode that cooperates with the smart phone 100A. In the specific mode, the in-vehicle apparatus 100 functions as an input-output device of the smartphone 100A. For example, icons associated with applications installed in the smartphone 100A are displayed on the display unit 150 of the in-vehicle apparatus 100, and the user can start the applications of the smartphone 100A by touching the displayed icons. The video signal or audio signal that is streamed by the smart phone 100A is transferred to the in-vehicle device 100, and these video signal or audio signal are output to the display unit 150 or the voice output unit 160. In addition, the message function may be executed on the side of the smart phone 100A, and in this case, the smart phone 100A may transfer image data (for example, data including a message transmitted and received during a chat) associated with the message function to the in-vehicle device 100, and display the image data on the display unit 150 of the in-vehicle device 100. The same image data may be displayed on both the display unit of the smart phone 100A and the display unit 150 of the in-vehicle device 100.

The display unit 150 displays a road map generated by the navigation unit 130, or displays an image associated with various applications installed in the in-vehicle device 100 when executed. For example, in the case of an in-vehicle WeChat action, chat or messages transmitted and received between users are displayed in time series.

The voice output unit 160 outputs an audio signal generated by the navigation unit 130 or a read voice of a received message when an application of a WeChat mounted in the in-vehicle device 100 is executed.

The storage unit 170 stores data (e.g., a road map database) required for the in-vehicle apparatus 100, or stores various application software or programs executable by the in-vehicle apparatus 100. The control unit 180 controls the operation of each unit of the in-vehicle apparatus 100. In one embodiment, the control unit 180 includes a microprocessor or a microcontroller including a ROM/RAM, etc., and the control unit 180 controls each unit by executing a program stored in the ROM/RAM.

In the present embodiment, the control unit 180 causes the in-vehicle apparatus 100 to have a message function or a chat function by executing an application program for a message such as a WeChat. In the case of utilizing the message function, initially, the user performs user registration in the message system of the server 40. Then, if the message application program is operated in the user terminal, the server 40 accepts the message transmitted from the user terminal, and transmits the accepted message to the corresponding other user terminal. The user designates a transmission address to transmit a message (or an email) to a specific counterpart, or designates a group to share a transmitted and received message within the group. The message can contain text data, image data, voice data.

Fig. 5 is a diagram showing a functional configuration of a message function executed in the message application according to embodiment 1 of the present invention. The message function 200 of the present embodiment includes a group registration section 210, a message transmission and reception section 220, a message editing section 230, a message display section 240, a message playing section 250, a length detection section 260, and a user name simplifying section 270.

The group registration section 210 groups members (users) sharing a message and registers them. For a group, a name for identifying the group is given. For example, user A, B, C is included in group X, user A, D, E, F is included in group Y, and user A, G, H, I, J is included in group Z. In the following description, for ease of explanation, the user a is taken as the user of the in-vehicle apparatus 100.

When registering a group, the user a creates a group name via the input unit 110, and inputs a user name included in the created group. The group registration section 210 generates group information in response to an input operation of the user a, stores the group information in the storage section 170, and transmits the group information to the server 40 via the communication section 140. The server 40 registers the accepted group information in association with the user a. For example, when the user a designates the group X to chat, the message created by the user a is transmitted to the terminal of the user B, C in the group X via the server 40. For example, if user B replies to user a's message, the message is sent to user a's and user C's terminals. In this way, information is transmitted and shared among the users in group X.

The message transmitting/receiving unit 220 receives the message transmitted from the server 40 via the communication unit 140, or transmits the edited message to the server 40 via the communication unit 140. The message editing unit 230 edits a message based on information input by the user a via the input unit 110 when a message is newly created or when a received message is returned. User a can input information through a key device or voice. The message composed by the message composing section 230 is transmitted to other user terminals via the server 40 by the message transmitting/receiving section 220.

The message display unit 240 displays the message edited by the message edit unit 230 on the display unit 150, or displays the message received by the message transceiver unit 220 from another user on the display unit 150. When chat is performed in the group, the transmission and reception of the series of messages are displayed in time series.

The message playing section 250 outputs the voice of the message received by the message transmitting and receiving section 220. Specifically, the user name of the sender and the text body thereof included in the message are converted into voice data, and output from the voice output unit 160. When it is detected that the length of the user name is equal to or longer than a predetermined value, the message playing unit 250 plays the simplified user name instead of the original user name.

The length detection unit 260 extracts the user name of the sender included in the message received by the message transmission/reception unit 220, and detects the length of the user name. The user name is a character string composed of a combination of characters such as kanji, latin letters, numerals, and signs, and the length detection unit 260 detects the length of the user name by counting the character string. The detection result is supplied to the user name simplifying unit 270.

The user name simplifying unit 270 determines whether or not the length of the user name is equal to or greater than a predetermined value based on the detection result of the length detecting unit 260, and if it is determined that the length is equal to or greater than the predetermined value, simplifies the user name so as to be distinguishable from other user names. The following will be left with respect to a specific simplified method. The determination result of the user name simplifying unit 270 is supplied to the message playing unit 250, and when it is determined that the length of the user name is equal to or longer than a predetermined length, the message playing unit 250 plays the user name simplified by the user name simplifying unit 270 in a voice.

Fig. 6 is an operation flow when a received message is played in voice. If a message is received from the counterpart via the messaging unit 220 (S100), the length detection unit 260 extracts a user name that is a sender of the message, and detects the length of the user name (S110). Next, the user name simplifying unit 270 determines whether or not the length of the user name is equal to or greater than a predetermined value (S120), and if it is determined that the length is equal to or greater than a predetermined value, simplifies the user name so as to be distinguishable from other user names (S130). On the other hand, when it is determined that the length of the user name is not equal to or longer than a certain length, the user name is not simplified. Next, the message playing section 250 plays the user name or the simplified user name and the message body in voice, and outputs the same from the voice output section 160 (S140).

Next, a specific user name simplifying method of the present embodiment will be described.

(concrete example 1)

Fig. 7 shows an example in which 4 user names are registered as members in 1 group. For example, assume that the received message contains a user name of "universe superinvincible kitten". At this time, the length detection unit 260 detects the number of characters 9 of the user name "universe super-invincible kitten", and when the user name simplification unit 270 determines that the number of characters 9 is equal to or greater than a predetermined value, the user name simplification unit 270 performs a simplified process for the user name "universe super-invincible kitten" so as to be distinguishable from other user names.

In specific example 1, the user name simplifying unit 270 simplifies the user name so as to extract a subject from the user name and delete a modifier. In the "universe super invincible kitten" the subject is "kitten" and the modifier is "universe, super, invincible, small", so the user name is simplified to "kitten". In one embodiment, the user name simplifying unit 270 may analyze the user name in a morpheme manner and recognize the subject or modifier of the user name.

In addition, it is preferable to judge whether or not the simplified subject is included in another user name, and if so, the subject may be confused with another user name, and therefore, one modifier is retained for simplification. In the above example, the subject is "cat" and the user name simplifying unit 270 determines whether or not "cat" is included in the user names of the other 3 persons in the group. Here, the other user names do not include "cat", and thus the simplified user name is "cat". If the other user name includes "cat", a modifier is retained so as to be distinguishable from the other user name, and the simplified user name is "kitten cat", or "universe cat", or "super cat", or "invincible cat".

(specific example 2)

Fig. 8 shows that when 4 user names are registered as members in 1 group, and the user name "universe super-invincible kitten" is simplified as in the case of specific example 1, the user name simplifying unit 270 extracts keywords from the user names so as to be distinguishable from other user names.

Keywords are, for example, subjects, nouns, etc., and for example, a user name is subjected to morpheme analysis to extract subjects, nouns, etc. In the case where the user name includes a subject or a noun, a priority to give priority to one of the subject or the noun may be set in advance.

In this example, the user name is abbreviated as "cat" and since the other user names do not include "cat" and can be distinguished from the other user names, the user name simplifying unit 270 determines that it is appropriate. On the other hand, the user name is simplified to "universe", and since the keyword is included in the other user names "universe superinvincible puppy", the user name simplifying unit 270 determines that the simplification is inappropriate to "universe". In this case, "cat" as the next candidate is selected as a keyword, and is reduced to the keyword.

(specific example 3)

Fig. 9 shows a list of 4 user names used in the transmission and reception of a message. Since the length of these user names is equal to or longer than a predetermined value, the user name simplifying unit 270 simplifies the user names when each user name is played.

For example, in the case where the user name is "manufacturing technology muesli", if the user name is subjected to morpheme analysis, the user name is composed of words of "manufacturing", "technology", "muesli". When simplifying the user name, the user name simplifying unit 270 extracts the first characters of the modifier "make" and "technique" and combines the first characters with the subject "mr. Mueller" to simplify the first characters to "mr. Mueller". Other usernames are also simplified to "Mr. Shengbaoli", "Pinbao Mr. and" Shangqi Mr. poplar ".

(specific example 4)

Fig. 10 (a) illustrates a user name, and fig. 10 (B) illustrates a character rarely used among the user names. In this case, as shown in fig. 10 (C), the user name simplifying unit 270 deletes the rarely used characters from the user name, and simplifies the user name to a user name composed of commonly used characters. In addition, the few used characters or the few used characters may be registered in advance in a dictionary, and whether the few used characters or the few used characters are recognized by the dictionary may be determined. In addition, in the case where the user name includes a special character, the special character may be excluded from the user name by the same method.

(specific example 5)

Fig. 11 is an example of chat using different names or nicknames for the user name of a message. In such a case, the user name is reduced to a name or nickname. The figure is an example of: in the body of the first message, "swordlike" is described as a name of the transmitting party, and in response thereto, the message is received from the user name "magic river lake swordlike". In this case, user name simplifying unit 270 determines that the name of the user name "magic river and lake swordsman" is "swordsman", and simplifies the user name to "swordsman". The user name simplifying unit 270 may identify and simplify not only the current message transmission and reception but also the name or nickname of the user name from the history of past message transmission and reception.

Next, a message playing operation according to embodiment 2 of the present invention will be described with reference to fig. 12. In embodiment 2, when a message is received from the partner (S200), the user name simplifying unit 270 determines whether or not the first message is to be played (S210). That is, it is determined whether the chat currently being performed is the original user name. In the case where the user name initially appears, the user who received the message sometimes cannot think of the real user name from the reduced user name. Therefore, when the user name appears first, the user name simplifying unit 270 does not simplify the user name, but plays the user name, and simplifies the user name from the next time. Thus, the real user name can be recognized from the simplified user name. The operations other than the above are the same as those of embodiment 1.

Next, a message playing operation according to embodiment 3 of the present invention will be described with reference to fig. 13. In embodiment 3, when the length of the user name is equal to or greater than a predetermined value (S300 to S320), the length detection unit 260 detects the length of the body of the received message (S330), and the user name simplifying unit 270 determines whether or not the length of the body of the message is equal to or greater than a predetermined value (S340). Then, when the length of the message body is equal to or longer than a predetermined value, the user name simplifying unit 270 simplifies the user name so as to be distinguishable from other users (S360), and if the length of the message body is smaller than the predetermined value, does not simplify the user name.

When the length of the message body is equal to or longer than a predetermined value, the voice playing of the message body takes a relatively long time, and therefore, in such a case, the efficiency of the playing time of the message is improved by simplifying the user name. On the other hand, when the message body is short, the play time is not greatly prolonged even if the user name is not simplified, and the user is not provided with unpleasant feeling.

Next, a message playing operation according to embodiment 4 of the present invention will be described with reference to fig. 14. In embodiment 4, unlike embodiments 1 to 3, simplification of a user name is performed irrespective of the length of the user name or the length of a message body. In fig. 14 (a), if a message is received from the other party (S400), the user name simplifying unit 270 then determines whether the received message is an important message (S410), and if it is determined that the received message is important, simplifies the user name (S420).

In fig. 14 (B), if a message is received from the other party (S400), the user name simplifying unit 270 then determines whether or not the received message needs to be immediately played back (S450), and if it is determined that the received message needs to be immediately played back, simplifies the user name (S420). For example, when the message includes information on the address location during traveling, the user name simplifying unit 270 determines that the message is an important message or a message that needs to be immediately played. For example, when determining whether a message is important or whether immediate play is required, it is possible to use: whether the message contains a term consistent with a keyword registered in advance in a dictionary, or whether the message is a message transmitted from a specific sender, and identification information indicating whether an important or immediate play flag is attached to the message.

As such, in embodiment 4, in the case where a message is important or needs to be immediately played, the play time of the user name is shortened by simplifying the user name, so that the voice output of the message body is immediately heard. In the above embodiment, whether or not an important message is determined individually and whether or not immediate playback is necessary is determined, but 2 determinations may be used as the superimposition condition. That is, the user name is simplified only when the message is determined to be important and the immediate play is required.

Next, a message playing operation according to embodiment 5 of the present invention will be described with reference to fig. 15. In embodiment 5, when a message is received from a member in the group (S500), the user name simplifying unit 270 determines whether the user name of the message is a friend (S510), and if it is determined that the message is not a friend, the user name is simplified (S520). The members within the group are not limited to all friends, and thus, in the case where a message is received from a counterpart that is not a friend, the user name of the counterpart is simplified.

In one embodiment, when the group registration unit 210 registers the user name in the group, the user name simplifying unit 270 determines whether the sender of the message is a friend based on the registered information, as attribute information, together with whether the user name is a friend. As described above, according to the present embodiment, by simplifying a user name that is not a friend, a message body can be quickly played without taking time in playing the user name. In the above example, whether the user relationship is a friend was determined, but this is an example, other attribute relationships (for example, relatives, colleagues of a company, and the like) between users may be determined, and the user name may be simplified based on the determination result.

In addition, in embodiments 4 and 5, an example is shown in which the user name is simplified irrespective of the length of the user name, but the present invention is not limited thereto, and embodiments 4 and 5 may be combined with embodiments 1 to 3, respectively. For example, in embodiment 4, the user name may be simplified when the length of the user name is equal to or longer than a certain length and is an important message, or in embodiment 5, the user name may be simplified when the length of the user name is equal to or longer than a certain length and the user name is not a friend.

The specific embodiments of the present invention have been described in detail above, but the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims.
