In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.
Please refer to fig. 1, fig. 1 is an application scenario to which the technical solution of the embodiment of the present application can be applied, where the application scenario includes a plurality of users (e.g., user 1 and user 2) and a plurality of electronic devices (e.g., electronic device 1, electronic device 2, electronic device 3, and electronic device 4), and the electronic devices may be, for example, mobile phones, computers, or other smart home devices (e.g., air conditioners, refrigerators, smart fans, humidifiers) that can be woken up by voice, and the like, and the embodiment of the present application is not limited. In the application scenario, after the user 1 and the user 2 pass the voiceprint feature information verification, the system can be unlocked to reset the wake-up word. After extracting the voiceprint feature identity information of the user, the electronic device may refer to the extracted voiceprint feature information as target voiceprint feature information, and then compare the target voiceprint feature information with the voiceprint feature information pre-stored in the electronic device, and if the target voiceprint feature information is successfully matched with the pre-stored voiceprint feature information, the corresponding electronic device acquires voice information used by the user to reset the wakeup word. It should be noted that, in this application scenario, the types and the numbers of the electronic devices that the user 1 and the user 2 can reset the wake-up word are the same, but in a specific embodiment, different users can reset the wake-up word for different electronic devices, and the embodiments of the present application are not limited to the types and the numbers of the electronic devices that reset the wake-up word.
The technical scheme provided by the embodiment of the application is described in the following with the accompanying drawings of the specification.
Referring to fig. 2, fig. 2 is a method for resetting a wake-up word according to an embodiment of the present application, where the method may be performed by any electronic device in the application scenario shown in fig. 1, and in a specific implementation process, the electronic device may be, for example, a mobile phone, a tablet, a computer, or other smart home devices (e.g., an air conditioner, a refrigerator, a smart fan, a humidifier) capable of performing voice wake-up. It should be noted that, in the embodiment of the present application, a method for resetting a wake-up word is provided, but in a specific implementation process, when a user first sets a wake-up word, the user may also set the wake-up word by the method, that is, when the user first sets the wake-up word, the user may first perform identity verification by the method, and after the identity verification passes, the user may first set the wake-up word. The flow of the method of resetting the wake-up word in fig. 2 is described as follows.
Step 201: and judging whether a reset triggering condition for resetting the awakening word is met.
The wake-up word refers to a wake-up instruction used by a user to wake up the electronic device by voice, and may also be directly understood as an unlock word used by the user to unlock the electronic device by voice. For example, the user may use an unlocking word to unlock the mobile phone when the mobile phone is in the locked state, or use a wake-up word to input "turn on the air conditioner" when the user wants to turn on the air conditioner, and so on.
The reset trigger condition is a condition for triggering the electronic device to reset the originally stored wake-up word, so that when the reset trigger condition is met, it indicates that the electronic device needs to be reset by the corresponding wake-up word. In the embodiment of the present application, for example, the following three reset trigger conditions may be preset.
First reset trigger condition
Taking the application scenario described in fig. 1 as an example, the reset trigger condition may be that the electronic device detects that some specific operations are performed by a user, for example, the specific operations are referred to as preset trigger operations, that is, when the preset trigger operations are detected by the user, it is determined that the reset trigger condition is satisfied. The preset triggering operation may be, for example, that a user presses a specific key, or that the user inputs a specific control statement entering a wake-up word reset mode by voice, or that other users actively trigger an operation of resetting a wake-up word, or the like, and the embodiment of the present application is not limited. For example, when the mobile phone detects that the user performs the operation of long-pressing the designated area of the screen in the screen locking state, the mobile phone considers that the user needs to enter the reset of the wake-up word, and further can trigger the subsequent operation of entering the reset wake-up word.
That is to say, when the electronic device detects a specific operation performed by the user, the user is considered to have a need for resetting the wake-up word, and thus, when the user confirms that the user forgets the wake-up word or resets the wake-up word according to the actual need of the user, the electronic device can be directly controlled to reset the wake-up word through some specific operations, so that the direct and effective triggering of resetting the wake-up word is performed according to the manual triggering of the user, and the triggering accuracy and effectiveness are high.
Second reset trigger condition
The reset trigger condition may also be that the electronic device detects that the number of times of errors of the wake-up word input by the user is incorrect exceeds a preset number of times, that is, when the number of times of errors of the wake-up word input by the user is detected to exceed a certain number of times, it is determined that the reset trigger condition is satisfied. Still take the wakeup word for waking up the mobile phone as an example, when the user needs to wake up the mobile phone, for example, the user needs to input the wakeup word whose content is "mobile phone unlock" to wake up the mobile phone, but the user inputs the wakeup word of "please turn on the mobile phone" to wake up the mobile phone normally, if the user continuously inputs multiple wrong wakeup words, and the number of times of the wakeup word error detected by the mobile phone by the user exceeds the preset number of times, the user is considered to need to reset the wakeup word of the mobile phone, and the preset number of times may be, for example, three times or five times, and the user may set the preset number of times according to the user's own needs, which is not limited in the embodiments of the present application.
That is to say, the user may input a plurality of wrong wake-up words without knowing that the user forgets the wake-up words, when the electronic device detects that the number of times of errors exceeds a certain number of times, the user may be prompted to reset the corresponding wake-up words, and the reset wake-up words are automatically triggered by detecting the number of times of the input errors of the wake-up words, so that automatic triggering of the electronic device may be realized, user experience is improved, and the intelligence of the electronic device is higher.
Third reset trigger condition
The reset trigger condition may also be a time for reaching a specified reset wakeup word preset for the electronic device, that is, when a preset reset time for the wakeup word is reached, it may be determined that the reset trigger condition is satisfied. The period of the timed reset wake-up word can be preset for the electronic equipment, so that the electronic equipment can periodically and automatically prompt the user to reset the wake-up word, and the period of the reset wake-up word can be set to be 15 days or 1 month, and the like, because the user does not need to frequently reset the wake-up word. Therefore, the electronic equipment can prompt the user to reset the awakening words at regular time, so that the automatic triggering of the electronic equipment is realized, and the timeliness of the reset awakening words is also ensured.
Step 202: and when a reset triggering condition of the reset awakening word is met, acquiring target voiceprint characteristic information of the user.
The target voiceprint characteristic information is voiceprint verification information of the current user, which needs to be acquired before the electronic equipment acquires reset voice information for resetting the wake-up word and further resets the wake-up word, and is used for verifying whether the current user has the authority for resetting the wake-up word.
That is to say, when the reset trigger condition for resetting the wakeup word is met, the electronic device needs to perform authentication on the user currently performing the operation of resetting the wakeup word, and determines whether the current user has the authority to reset the wakeup word according to the authentication result.
In a possible implementation, the electronic device may store a specific sentence in advance, where the specific sentence may be a custom sentence previously entered into the device by the user, and for example, the specific sentence may be referred to as a preset feature sentence. When the user identity needs to be verified to reset the wake-up word, the electronic device first plays the feature sentence, and then the user repeats the feature sentence played by the device within a preset time duration, for example, the user voice information containing the repeated feature sentence is called as target voice information. After a user inputs target voice information, the electronic equipment extracts a target characteristic statement in the target voice information, wherein the target characteristic statement is a statement which is restated by the user based on the played characteristic statement, then judges whether the target characteristic statement and a preset characteristic statement meet a preset matching condition or not, extracts voiceprint characteristic information in the target voice information when the preset matching condition is met, and determines the extracted voiceprint characteristic information as target voiceprint characteristic information for comparison with voiceprint characteristic information of a current user which is stored in the electronic equipment in advance.
In the embodiment of the application, the electronic equipment verifies the identity of the user by inputting the voice information containing the preset characteristic sentences repeated by the user and then extracting the voiceprint characteristic information of the voice information, so that the validity of the identity information of the user is ensured, and the safety of the subsequent reset operation of the awakening words is improved.
In a possible implementation manner, when the user repeats the preset feature sentences played by the device, the problem of increasing or decreasing the characters or the problem of word order with wrong character order may occur, so that when the target voice information entered by the user is obtained, the electronic device may extract the voiceprint feature information of the user only when it is determined that the target feature sentences and the preset feature sentences contained in the target voice information satisfy a certain condition (that is, the preset matching condition).
After extracting a feature sentence repeated by the user based on the preset feature sentence, the electronic device compares the characters included in the feature sentence with the characters included in the preset feature sentence, and determines a matching value between the characters, for example, the determined matching value is referred to as a first matching value. Meanwhile, the electronic device further determines a matching value between the text sequence in the target feature sentence and the text sequence in the preset feature sentence, for example, the matching value is referred to as a second matching value, when the first matching value is greater than a first preset threshold and the second matching value is greater than a second preset threshold, it is determined that a preset matching condition is satisfied, and then the electronic device extracts voiceprint feature information in the user voice information. The first preset threshold and the second preset threshold may be thresholds set by a user according to a requirement of the user, and the user may modify the preset thresholds in real time according to needs.
In a specific embodiment, for example, the preset feature sentence is determined as "cloud made by rain in wind", and when the user repeats the sentence based on the preset feature sentence, the preset feature sentence is repeated as "cloud made by rain in wind", at this time, the target feature sentence repeated by the user has one more character than the preset feature sentence, and the electronic device determines a matching value of one character (i.e., the first matching value) according to the situation. The word sequence in the target characteristic sentence is basically consistent with the word sequence of the preset sentence, but a word "one" is inserted between the third word and the fourth word, and the electronic equipment determines the matching value of the word sequence (namely the second matching value) according to the situation. It should be noted that when the target feature sentence and the preset feature sentence contain the same characters, it is proved that the first matching value at this time is the largest and the characters are completely matched, and when the target feature sentence and the preset feature sentence contain the same character sequence, it is proved that the second matching value at this time is the largest and the character sequence is completely matched.
In a specific implementation, for example, the first preset threshold is determined to be 80%, and the second preset threshold is determined to be 85%. After extracting the voiceprint feature information of the current user, the electronic device needs to compare with the preset voiceprint feature information, and further determines a first matching value and a second matching value, for example, at this time, the electronic device determines that the first matching value is 90%, the second matching value is 86%, and both the first matching value and the second matching value satisfy a condition that is greater than a preset threshold value, so that it may be determined that the preset matching condition is satisfied at this time. Alternatively, for example, the first matching value is 70%, the second matching value is 90%, or the first matching value is 85%, and the second matching value is 80%, that is, only one of the first matching value and the second matching value satisfies the condition that is greater than the preset threshold, and then the preset matching condition is not satisfied. Or, the first matching value is 70% and the second matching value is 75%, and neither the first matching value nor the second matching value satisfies the condition of being greater than the preset threshold, and then the preset matching condition is not satisfied.
In the embodiment of the application, whether voiceprint feature information of user voice is extracted or not is determined by comparing the characters and the character sequence in the user repeat sentence with the characters and the character sequence of the preset sentence, so that the validity of obtaining the voiceprint feature information is ensured, and the operation of resetting the awakening words is ensured to have certain safety by means of limiting conditions.
Step 203: and judging whether the acquired target voiceprint characteristic information is matched with the preset voiceprint characteristic information.
The preset voiceprint feature information refers to voiceprint feature information in a preset feature sentence, which is extracted when a user inputs the preset feature sentence, and then the voiceprint feature information is stored in the electronic device and is used for being compared with the voiceprint feature information acquired in real time so as to authenticate the identity of the user.
After the electronic device acquires the target voiceprint feature information of the user who currently performs wakeup word reset, the acquired target voiceprint feature information needs to be compared with voiceprint feature information stored in the electronic device in advance to verify the identity of the user.
Step 204: and when the obtained target voiceprint characteristic information is matched with the preset voiceprint characteristic information, acquiring reset voice information for resetting the awakening words, and resetting the awakening words according to the reset voice information.
In a possible implementation manner, after determining that the current user has the authority to reset the wake-up word, the electronic device obtains reset voice information used by the user to reset the wake-up word, where the reset voice information includes the content of the wake-up word that the user currently needs to reset the corresponding wake-up word, and then resets the corresponding wake-up word according to the obtained reset voice information.
In a possible implementation manner, after acquiring the reset voice information, the electronic device needs to determine whether the acquired reset voice information meets a certain condition, and when the certain condition is met, resets the corresponding wake-up word according to the reset voice information. In the embodiment of the present application, the electronic device may determine whether to reset the wake-up word according to the reset voice message in at least three ways.
First mode of determination
After acquiring the reset voice information of the user, the electronic device determines whether the reset voice information meets a preset reset time condition, wherein the preset reset time condition is a time condition for judging whether the awakening words can be reset according to the current reset voice information, so that when the preset reset time condition is met, the electronic device indicates that the corresponding awakening words can be reset according to the current reset voice information, and at the moment, the electronic device resets the awakening words according to the acquired reset voice information to acquire new awakening words.
In a possible implementation manner, the preset reset time condition may be that a specific time is preset, for example, the preset time is set to 1 minute, the electronic device starts to time after entering the wake-up word reset mode, and the voice information of the user acquired within 1 minute is taken as effective reset voice information, the effective reset voice information may be understood as a reset new wake-up word, and the electronic device resets the wake-up word according to the effective voice information, for example, within one minute, the voice information of the user acquired by the electronic device is "moon represents my heart", and then "moon represents my heart" is taken as a new wake-up word and is stored. It should be noted that after the electronic device enters the reset mode for 1 minute, other voice information of the user may be acquired, but the voice information is invalid, that is, the electronic device does not reset the wakeup word according to the voice information.
In the embodiment of the application, the electronic equipment presets the time for acquiring the voice resetting information of the user by the electronic equipment, so that the timeliness of the reset awakening words can be ensured.
In another possible embodiment, the preset reset time condition may be a preset specific time, and the user must enter a new wake-up word to be reset into the electronic device within this time, for example, the preset time is set to 30 seconds, the electronic device starts to time after acquiring the voice of the user, the user needs to enter the new wake-up word into the electronic device within 30 seconds, if the electronic device acquires that the new wake-up word of the user is "mouse love rice" within 30 seconds of the preset time, the mouse love rice "is taken as the new wake-up word, of course, other voice information of the user may be acquired within a time other than 30 seconds after the electronic device acquires the voice of the user, but the electronic device does not reset the wake-up word according to the voice information. Thus, the timeliness of resetting the wake-up word can be improved.
Second determination method
After acquiring the reset voice information of the user, the electronic device determines the occurrence number of reset words and sentences in the reset voice information, the reset words and sentences refer to new wake-up words for resetting, and when the occurrence number of the reset words and sentences in the reset voice information is greater than or equal to a preset number, the electronic device resets the reset words and sentences as the new wake-up words to obtain the new wake-up words, wherein the preset number can be the number determined by the user according to the self requirement.
In a possible implementation manner, for example, the number of times that a reset word and sentence preset by a user needs to appear is 3, the electronic device determines the number of times that the reset word and sentence appears after acquiring reset voice information of the user, for example, the reset word and sentence at this time is "love china", when the number of times that the reset word and sentence "love china" appears is 2, the preset number of times is not reached, at this time, the electronic device does not reset a wakeup word, and when the number of times that the reset word and sentence "love china" appears is 4, the preset number of times is already greater than 3, the electronic device resets the wakeup word by using "love china" as a new wakeup word.
In the embodiment of the application, whether the awakening words are reset or not is determined by presetting the occurrence frequency of the reset words and sentences, so that the reset of the awakening words can be ensured to be accurate and effective.
Third determination method
After the electronic equipment acquires the reset voice information of the user, the quantity of characters contained in the reset words and sentences in the reset voice information is determined, the reset words and sentences refer to new awakening words for resetting, and when the quantity of the characters of the reset words and sentences belongs to the range of the preset quantity, the electronic equipment resets the reset words and sentences as the new awakening words to obtain the new awakening words. The preset number range can be a text number range determined by a user according to the needs of the user, under a common condition, when an awakening word is too long, the user is difficult to memorize, when the user awakens by voice, errors are easy to occur, the electronic equipment cannot be awakened effectively, when the awakening word is too short, the mistaken awakening rate is high, and the safety is not high enough, so that the user can limit the text number of the awakening word according to the conditions of the user, the word awakening time is ensured to be accurate and effective, and the text number range is limited.
In a possible implementation manner, for example, the number of characters of a reset word and sentence preset by a user is greater than or equal to 5 and less than or equal to 10, after the electronic device acquires reset voice information of the user, the electronic device determines the number of characters of the reset word and sentence, for example, the reset word and sentence is "love China", the number of characters of the reset word and sentence is 4, and the preset number of characters is not satisfied, and the electronic device does not reset the reset word and sentence as a new wake-up word; for example, the reset word and sentence at this time is "i want a work with high salary", the number of characters of the reset word and sentence at this time is 12, the preset number range of characters is not satisfied, and the electronic device does not reset the reset word and sentence as a new wake-up word; for example, when the reset word and sentence is acquired as "moon represents my heart", the number of characters of the reset word and sentence is 7, and the preset range of the number of characters is met, the electronic device resets the awakening word by using "moon represents my heart" as a new awakening word.
In the embodiment of the application, whether the awakening words are reset or not is determined by presetting the number of the words of the reset words and sentences, so that the flexibility and the effectiveness of resetting the awakening words are improved.
In the embodiment of the application, when the user needs to reset the wake-up word for waking up the electronic device, the identity can be verified in a voiceprint feature verification mode, when the user determines that the user has the right to reset the wake-up word through identity verification, the corresponding wake-up word can be reset according to the user's needs, and when the user forgets the wake-up word or wants to reset the wake-up word according to the user's needs, a method for safely and effectively resetting the wake-up word is provided, so that the user experience is improved.
