Detailed Description
Referring now to the drawings, in which like numerals represent like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
It can be understood that the execution subject of the embodiment of the present application may be a terminal device such as a smart phone or a tablet computer.
Referring to fig. 1, fig. 1 is a schematic flow chart of a voiceprint feature updating method according to an embodiment of the present application, where the flow chart may include:
in 101, when it is determined that the voiceprint feature of the terminal owner needs to be updated, a history that a recording process in the terminal is started is obtained.
With the development of technology, the interaction mode between human and machine becomes richer and richer. In the related art, a user can control a terminal through voice, that is, after receiving voice information sent by the user, the terminal can analyze the voice information to obtain a control instruction. Before executing the control instruction, the terminal needs to extract voiceprint features from the voice information and perform voiceprint recognition on the user according to the extracted voiceprint features. And only after the voiceprint recognition is passed, the terminal can execute the control instruction corresponding to the voice information. However, in the related art, the terminal has poor flexibility in updating the saved voiceprint feature.
In this embodiment, for example, when it is determined that the voiceprint feature of the owner stored in the terminal needs to be updated, the terminal may first obtain a history that the recording process is started.
It should be noted that the recording process in the terminal may be started by the terminal when the user makes a call, or by the terminal when the user sends voice information when using the instant messaging application, or by the terminal when the user starts the recording application to record an audio/video file, or the like. In these cases, the terminal recording process in the terminal wakes up the microphone and picks up the user's voice using the microphone.
At 102, voice information is obtained from the master based on the history.
For example, after acquiring the history that the recording process in the terminal is started, the terminal may acquire the voice information from the terminal owner according to the history.
In 103, target voiceprint features are extracted from the speech information.
For example, after acquiring voice information from the terminal owner, the terminal may extract voiceprint features from the voice information, i.e., obtain target voiceprint features.
At 104, the voiceprint feature of the owner stored in the terminal is updated based on the target voiceprint feature.
For example, after obtaining the target voiceprint feature, the terminal may update the previously saved voiceprint feature of the owner in the terminal according to the target voiceprint feature.
It can be understood that, in this embodiment, when the voiceprint feature of the owner saved in the terminal needs to be updated, the terminal may obtain the voice information of the owner according to the history that the recording process is started. Then, the terminal can extract the target voiceprint feature from the voice message, and update the voiceprint feature of the owner stored in the terminal according to the target voiceprint feature. Because the embodiment can acquire the main voice for updating the voiceprint feature according to the history that the recording process is started, the embodiment can improve the flexibility of the terminal when the voiceprint feature is updated.
In addition, since the voiceprint characteristics of the user may change in some cases, for example, when the throat of the user is inflamed, the present embodiment may improve the accuracy of the terminal in performing voiceprint recognition using the voiceprint characteristics by updating the voiceprint characteristics of the owner stored in the terminal, and avoid inconvenience in operation of the user due to the fact that the voiceprint characteristics of the owner stored in the terminal are too old.
Referring to fig. 2, fig. 2 is another schematic flow chart of a voiceprint feature updating method according to an embodiment of the present application, where the flow chart may include:
in 201, when the number of times that the voiceprint feature of the user is continuously unmatched with the owner voiceprint feature stored in the terminal reaches a preset value, the terminal performs owner identity authentication on the user.
For example, when a user completes a certain operation through a voice control terminal, the terminal needs to extract a voiceprint feature from a voice uttered by the user, and match the voiceprint feature with a voiceprint feature of a user owner stored in the terminal. And only when the two are matched, the terminal can execute corresponding operation. And if the voiceprint feature of the current user acquired by the terminal is not matched with the voiceprint feature of the owner stored in the terminal continuously, and the continuous unmatched times reach a preset numerical value, the terminal can carry out owner identity verification on the user.
For example, when the voiceprint feature of the user does not match the voiceprint feature of the owner stored in the terminal for 5 consecutive times, the terminal may perform owner authentication on the user. In one embodiment, the terminal may perform the owner identity verification on the user through one or more of fingerprint recognition, iris recognition, face recognition, or password verification.
If the user does not pass the owner identity authentication, the terminal can judge the user as an illegal user and refuse to execute corresponding operation.
If the user passes the owner identity verification, 202 is entered.
In 202, if the owner identity verification passes, the terminal determines that the saved voiceprint feature of the owner needs to be updated.
For example, if the current user passes the owner identity authentication, that is, the current user is actually the owner, but the voiceprint feature of the current user cannot be matched with the voiceprint feature of the owner stored in the terminal, it may be considered that the voiceprint feature changes due to reasons such as throat inflammation, so that the voiceprint feature cannot be successfully matched with the voiceprint feature of the owner stored in the terminal. In this case, the terminal may determine that the voiceprint feature of the owner stored in the terminal needs to be updated.
In 203, the terminal acquires a history that the recording process is started.
For example, when it is determined that the voiceprint feature of the owner stored in the terminal needs to be updated, the terminal may obtain a history that the recording process is started. It is understood that the history of the recording process being started may include information such as the time the recording process was started.
It should be noted that the recording process in the terminal may be started by the terminal when the user makes a call, or by the terminal when the user sends voice information when using the instant messaging application, or by the terminal when the user starts the recording application to record an audio/video file, or the like. In these cases, the terminal recording process in the terminal wakes up the microphone and picks up the user's voice using the microphone.
At 204, the terminal predicts the time when the recording process is started next time according to the history record, and acquires the current time.
For example, after obtaining a history record of the recording process in the terminal being started, the terminal may predict the time when the recording process is started next time according to the history record, and obtain the current time.
Then, the terminal may obtain a predicted interval between the next time the recording process is started and the current time, and detect whether the interval is less than or equal to a preset interval.
If it is detected that the interval is less than or equal to the preset interval, 205 is entered.
If the interval is detected to be greater than the preset interval, then 206 is entered.
In 205, if the interval between the next time the recording process is started and the current time is less than or equal to the preset interval, the terminal obtains the voice information from the host when the recording process is started next time.
For example, if the terminal detects that the interval between the current time and the predicted time when the recording process is started next time is less than or equal to the preset interval, the terminal may obtain the voice information from the host when the recording process is started next time.
For example, on a weekday, a user may frequently make voice calls with friends or buddies during various time periods of the day. The terminal predicts the time of the next time that the recording process is started to be 10:00 and the current time to be 9:55 according to the history that the recording process is started, and the time interval between the time and the current time is 5 minutes and is less than the preset interval of 30 minutes. In this case, the terminal may acquire the voice information uttered by the owner when the recording process is turned on next time.
After the owner's voice is obtained, 209 may be entered.
It can be understood that, in this embodiment, the terminal predicts the time when the recording process is started next time through the history of the start of the recording process, and if the interval between the time and the current time is short, the terminal may obtain the voice uttered by the user when the recording process is started next time. By the method, the voice used for updating the voiceprint can be acquired under the condition that the user feels no, the user does not need to be reminded to output a section of voice additionally, extra time of the user can not be occupied, and therefore user experience is improved.
In 206, if the interval between the next time the recording process is started and the current time is greater than the preset interval, the terminal generates text information.
At 207, the terminal presents the text message to the owner and prompts the owner to read the text message.
At 208, upon detecting that the owner speaks the text message, the terminal obtains voice information from the owner.
For example, 206, 207, and 208 may include:
for example, according to the history that the recording process is started, the terminal predicts that the interval between the time when the recording process is started next time and the current time is larger than a preset interval, for example, the history of the recording process shows that the owner rarely makes a call or sends voice information to friends, buddies and the like. In this case, for example, the terminal predicts that the recording process is started next time after 24 hours, the terminal may generate the text message.
After generating the text message, the terminal may display the text message on a screen, thereby presenting the text message to the owner and prompting the owner to read the text message aloud.
When detecting that the owner reads the text information, the terminal can acquire the voice information sent by the owner. After the voice information of the owner is acquired, 209 is entered.
It can be understood that, in this embodiment, when the interval between the time when the recording process predicted by the terminal is started next time and the current time is longer, the terminal may generate the text message and prompt the owner to read the text message, so that when the owner reads the text message, the owner obtains the voice of the owner. By the mode, the voiceprint feature of the owner can be updated rapidly, so that the user can use the terminal conveniently.
In 209, the terminal extracts the target voiceprint features from the voice information.
At 210, the terminal updates the saved voiceprint characteristics of the owner based on the target voiceprint characteristics.
For example, 209 and 210 may include:
after the voice of the owner is acquired, the terminal can extract the target voiceprint feature from the voice, and then update the previously stored voiceprint feature of the owner according to the target voiceprint feature.
In an implementation manner, after the step of obtaining the current time in 204, this embodiment may further include the following steps:
if the interval between the time of starting the recording process next time and the current time is larger than the preset interval, the terminal prompts the owner to output random voice, wherein the voice time needs to reach the preset time;
when the owner outputs random voice, the terminal acquires voice information from the owner.
For example, according to the history that the recording process is started, the terminal predicts that the interval between the next time the recording process is started and the current time is greater than the preset interval, for example, the terminal predicts that the next time the recording process is started is 24 hours later, then the terminal may prompt the owner to randomly output a section of voice at this time, and the duration of the voice needs to reach the preset duration. For example, the duration of the voice needs to be at least 30 seconds.
When detecting that the owner outputs random voice, the terminal can acquire the voice information of the owner.
Then, the terminal may extract a target voiceprint feature from the voice, and then update the previously saved voiceprint feature of the owner according to the target voiceprint feature.
In some embodiments, after updating the voiceprint feature of the owner, the terminal may further obtain physiological feature information of the owner, and predict a time period required for the sound of the owner to return to normal according to the physiological feature information. For example, if the voiceprint characteristics of the owner change due to throat inflammation of the owner, the terminal can acquire physiological characteristic information of the owner and predict the time required for the throat inflammation of the owner to heal according to the physiological characteristic information. After the inflammation of the throat of the owner is healed, the voice of the owner is recovered to be normal, so the voice print characteristic of the owner stored in the terminal can be updated again by the terminal, and the use of a user is facilitated.
Referring to fig. 3 to 5, fig. 3 to 5 are schematic scene diagrams of a voiceprint feature updating method according to an embodiment of the present application.
The unique characteristics of the voiceprint are determined primarily by two factors, the first being the size of the vocal cavity, including specifically the throat, nasal cavity, oral cavity, etc., the shape, size and location of these organs determining the magnitude of vocal cord tension and the range of vocal frequencies. The second factor that determines the characteristics of the sound is the manner in which the organs of the sound are manipulated, including the muscles of the lips, teeth, tongue, soft palate, and palate, which interact to produce clear speech. That is, the voiceprint is closely related to the physiological characteristics of the human body. In everyday life, for example, a user's cold with inflamed throat can cause the user's voice to become dull. In this case, the user's voiceprint characteristics may change.
For example, a user may experience a change in vocal print characteristics due to inflammation of the throat. In this case, the user issues a voice instruction of "xiaohu please open the instant messaging application a" to the terminal, as shown in fig. 3. After receiving the voice command, the terminal can extract the voiceprint feature of the current user from the voice command so as to verify the validity of the identity of the current user.
For example, the terminal detects that the voiceprint feature of the current user does not match the voiceprint feature of the owner saved in advance. At this time, the terminal may prompt the user that the voiceprints are not matched, the voice instruction for opening the instant messaging application a cannot be executed, and prompt the user to re-input the voice instruction. For example, the user then utters "xiaohu" twice in succession, please open the instant messaging application a ", and the voiceprint features extracted by the terminal from the two speeches also do not match the voiceprint features of the owner that are saved in advance.
Because the voiceprint feature of the current user is not matched with the voiceprint feature of the owner saved in advance for 3 times continuously, the terminal can carry out owner identity verification on the current user at the moment. For example, as shown in fig. 4, the terminal may prompt the user to enter fingerprint information to verify the owner identity.
Thereafter, the current user inputs fingerprint information. The terminal can match the fingerprint information with the fingerprint information of the owner which is stored in advance. For example, the fingerprint information of the current user is successfully matched with the fingerprint information of the owner saved in advance, so that the terminal can determine that the current user is the owner. In this case, the terminal may determine that the voiceprint feature of the owner stored in the terminal needs to be updated.
When it is determined that the voiceprint feature of the owner stored in the terminal needs to be updated, the terminal can acquire the history record of the starting of the recording process, predict the time of the starting of the recording process next time according to the history record, and then acquire the current time.
Then, the terminal may obtain a predicted interval between the next time the recording process is started and the current time, and detect whether the interval is less than or equal to a preset interval. For example, the preset interval is 15 minutes.
For example, the time when the terminal predicts that the recording process is started next time is 10:00 of today, while the current time is 09:05, and the interval between the two is 55 minutes and is larger than the preset interval by 15 minutes. In this case, the terminal may generate a piece of text information and display the text information on the screen while prompting the current user to read the piece of text information, as shown in fig. 5.
When the text information read aloud by the user is detected, the terminal can acquire the voice information of the current user. Then, the terminal may extract voiceprint feature information of the current user from the voice information and determine it as a target voiceprint feature. Then, the terminal can update the previously saved voiceprint feature of the owner in the terminal according to the target voiceprint feature.
