Description
The present invention relates to an emergency alert method using speech recognition, a computer program for the same, and a recording medium therefor. More particularly, the present invention relates to an emergency alert method using voice recognition, The emergency alert method using voice recognition configured to generate an emergency alert when it is determined that a predetermined emergency situation has been recognized, and a computer program and a recording medium for the emergency alert method.
In emergency situations such as crime, a number of techniques have been proposed for generating emergency alarms through voice recognition even if the user does not operate the emergency bell button directly.
For example, Korean Patent No. 10-1031868 (registered on Apr. 21, 2011) generates an emergency signal using voice recognition, thereby allowing the intruder to inform the outside of the emergency situation in real time without knowing it, We propose a security system using speech recognition which can monitor the emergency situation in real time by transmitting the images collected by the image collecting unit.
As another example, Korean Patent No. 10-1590053 (filed on Jan. 25, 2016) discloses that there is a similar ambient noise due to the nature of the emergency bell system installed at a given location, We propose an emergency bell system which can obtain more accurate speech recognition result because it performs speech recognition after removing noise from speech signal according to ambient noise.
As another example, Korean Patent Registration No. 10-0807757 (registered on Feb. 20, 2008) discloses a method in which a change in a voice tone is compared with a normal voice tone, or a word stored in a word database and extraction In this paper, we propose a voice recognition automatic alarm system that generates an emergency operation signal in case of an urgent word and generates an alarm through an alarm generator and informs a security company or a police station of an emergency situation.
However, the above-described prior arts have a limitation in that when a user speaks a word or a sentence corresponding to an emergency situation while mistakenly or unconsciously recognizing an emergency situation in accordance with a result of speech recognition, the user can be mistaken for an emergency situation.
Some prior arts have proposed a technique for giving a score for a speech-recognized word and generating an emergency activation signal when it is judged to be a certain score or more. This method is also applicable to a case where one or more users are mistaken or unconscious There was still a limit to the possibility of being misunderstood as an emergency even if the word or sentence corresponding to the emergency situation was mentioned and the score was more than a certain score.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a speech recognition apparatus and a speech recognition method which judge whether a predetermined word is included in a user's voice input through a speech input means, And an emergency alert method using speech recognition configured to generate an emergency alert when a situation is determined, a computer program therefor, and a recording medium therefor.

FIG. 1 is an overall configuration diagram of an emergency alert system using speech recognition according to an embodiment of the present invention, and FIG. 2 is a configuration diagram of an emergency alert system using speech recognition according to an embodiment of the present invention.
From a functional point of view, the
For example, the voice input means 100 may be a conventional microphone for voice input, for example. Further, the
For example, the emergency alarm means 200 may be a sound output means such as a speaker, and as another example, a color, a brightness, and an illumination pattern may be controlled.
For example, the
On the other hand, the
This
3 is a flowchart of an emergency alert method using speech recognition according to an embodiment of the present invention.
In step S1, the
The voice input means 100 can be understood as a well-known speaker installed in a building space requiring security management such as a bank. Such loudspeakers may be installed, for example, in a concealed condition adjacent to the location of the respective bank teller's staff, or in the form of ornaments and attached to the staff. The voice input means 100 may be connected to the
In step S2, the
For example, these commands may be stored in a set of words or short sentences (eg, hands, do not move) that may be used by a security threat (eg, strength), for example, It is possible to naturally recognize the command.
As another example, a word or a short sentence (e.g., ooo) (a pre-artificially set customer name) is stored in a setting that is not related to security so that a person who threatens security may not be aware of the above situation. For example, It is also possible to make the recognition of the command possible in a situation where the employee naturally uses the command.
Such command setting can be appropriately selected in consideration of the usage environment in which the
In step S3, the
In step S4, the
For example, when 'hand in hand' is recognized as the first input command, the lighting in the building can be controlled to be changed to a preset illumination color or brightness. As another example, if 'do not move' is recognized as the first input command, music preset in the building can be output through the speaker.
This first stage alarm through the recognition of the first input command provides a function to inform other employees in the building where the situation occurs that the emergency alarm situation is occurring. This allows other employees who are familiar with such lighting or music alerts to take a second-level alarm through a second input command or a general notification procedure without knowing the person who caused the threat.
In step S5, the
For example, when a second input instruction of 'first hand input' is set as the first input instruction and a related input instruction 'Hong Gil Dong' is set as the first input instruction, The
As another example, when the second input instruction 'Do not move' is set as the first input instruction and the second input instruction 'Hello, Hello' is set as the related instruction related to the first input instruction, When the second input command is recognized, the
The first input instruction word and the second input instruction word may be input to each individual voice feature pattern so that association recognition can be performed only by the same person (employee), or even voice generated by different employees may satisfy only voice content and time condition The relationship recognition may be performed.
For example, in step S5, the input time point of the instruction word may be a time instant input time point of the instruction word.
In step S6, the
As described above, the emergency alarm operation in the step S4 is executed by using the emergency alarm means 200 interlocked with the
In addition, the emergency alert operation in step S6 is an emergency alert information transmission to the
On the other hand, in step S5, the steps S1 to S2 are further executed.
As a result, in step S51, the
In step S52, the
With this configuration, if different first input commands are input separately from the user or users with a little time lag, an emergency alarm can be generated without recognizing it as an error.
On the other hand, the association is such that one or more second input instructions are associated with one first input instruction, and a different emergency alert action is performed for each second input instruction combination for the first input instruction .
For example, if 'first hand' is set as the first input command and 'Hong Kil-dong' is set as the related command related to the first input command, an emergency alert is sent to the security authority so that an urgent dispatch is made within three minutes Can be set.
As another example, if 'Hands-on' is set as the first input command and 'Hong Gil-dong Hello' is set as the related command related to this, an emergency alarm is set .
After the step S6, in step S61, the
In step S62, when the reply of the acknowledgment information is confirmed, the
For example, when 'hand-in' is recognized as the first input command, the illumination in the building is changed to a preset illumination color, and then the emergency alarm information is received from the

In step S5, the steps S1 to S2 are further executed.
As a result, in step S511, the
In step S512, the
For example, when 'Hands-on' is set as the first input command and 'Not Hong Kil-Dong' is set as the cancellation command related to the first input command, the emergency alarm operation being executed by the first input command is canceled.
On the other hand, the determination in step S511 (whether or not the command is a cancel command of the first input command) is determined based on the determination in step S5101 (whether it is the same command as the first input command) or the determination in step S5 ) And a predetermined order or priority.
For example, if it is determined in step S5 that the input command is not a second input command having an affinity, it is determined in step S511, and if it is not a cancel command of the first input command, It is possible to judge a command to be input after inputting the first input command and perform an operation according to the command. This judgment order can be changed according to the setting. In the drawings, this is expressed as 'A' for convenience.

In step S5, the steps S1 to S2 are further executed.
As a result, in step S5101, the
In step S5102, the
With this configuration, when the same first input instruction word is inputted separately from a user or users with a slight time lag, an emergency alarm can be made without recognizing it as an error.
