Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a volume adjusting method applied to an audio adjusting apparatus, where the audio adjusting apparatus is disposed in an audio device, and as shown in fig. 1, the method includes the following steps:
The embodiment of the invention is suitable for adaptively adjusting the scene of the playing volume of the equipment according to the distance between the user and the audio equipment, namely when the audio equipment is in a working state, the position of a target user can be continuously tracked by adopting a target detection algorithm and a target tracking algorithm, so that the playing volume can be adjusted in real time according to the distance between the user and the audio equipment, and the playing effect of the audio equipment and the listening effect of the user are ensured.
However, in the process of tracking the target user, a phenomenon may occur that the distance between the user and the audio device cannot be detected due to the existence of a barrier between the audio device and the user, or a phenomenon may occur that a large change in the position of the user (actually, the positions of different users) is detected in a moment due to the existence of a plurality of persons near the audio device, for example, the movement distance exceeds 1 meter in 100 milliseconds, or a tracking failure may occur due to a failure of the audio device itself, which may both cause a positioning failure of the position of the user, that is, a situation that the target user is lost for tracking. In these cases, to retrieve the location of the target user, the audio playing module of the audio device may be controlled to send out a voice query signal, i.e., a first query voice may be played, such as "×, where are you? "to prompt the user to respond by the first query voice, wherein the audio playing module may be a device with an audio playing function, such as a speaker.
Wherein the first query voice may be a voice for prompting the target user to make a response voice or a voice for prompting the target user to avoid an object between the target user and the audio device.
That is to say, to achieve better query effect, the audio playing module may be controlled to emit query voices containing different information based on different scenes of losing the target user, for example, in the case that there are multiple users near the audio device and the position of the target user cannot be accurately located, the audio playing module of the audio device may be controlled to emit query voices prompting the target user to make a response voice, such as "twilight, where are you? "in response to the user, in the case that an obstructing object is detected between the audio device and the target user, the audio playing module of the audio device may be controlled to emit a query voice prompting the target user to avoid the object between the target user and the audio device, such as" Xiaoming, where are you? Please move slightly to the left "so that the user can move to the target location and can make a response voice after hearing the query voice.
Further, to ensure that the audio device emits a more targeted query voice, the first query voice may include a nickname of the target user to instruct the target user to respond to the query voice, so as to avoid other users from emitting interfering voices.
That is, the audio device may store therein the nickname information of the target user, and the step 101 includes:
and under the condition that the target user is determined to be lost, acquiring the nickname of the target user, and controlling an audio playing module of the audio equipment to play the first inquiry voice comprising the nickname of the target user.
In this embodiment, the user may enter the corresponding nickname information through voice entry or manually during registration, or, in the process of voice interaction between the user and the audio device, the audio device queries the nickname of the user, and the user inputs the corresponding nickname, so that the audio device binds the nickname of the user with the voiceprint feature of the user. In the embodiment, the position inquiry signal is sent to the target user in a targeted manner, so that the target user is sensitive to the inquiry signal, the signal can be responded quickly, and a response is made in time, so that the audio equipment can quickly locate the position of the user, and the playing volume of the audio equipment can be adjusted in time.
The audio device is an electronic device having a sound receiving function and a sound playing function, such as a sound box, in particular, a smart sound box, a mobile phone, a computer, an iPad, and the like.
It should be noted that, in this step, it may be specifically determined whether the target user is tracking lost by obtaining tracking state information of the target user, where the tracking state of the target user refers to a state in which the target user is in a tracked process, and may include a target lost state and a target still in two states, and the two states may be represented by 0 and 1 in a program respectively; and if the tracking state information of the target user indicates that the tracking state of the target user is lost, determining that the target user is lost.
Optionally, before the step 101, the method further includes:
tracking the position of the target user to obtain the real-time distance of the target user relative to the audio device;
and adjusting the playing volume of the audio equipment according to the real-time distance.
In order to ensure the audio effect of the audio device, the playing volume of the audio device can be adjusted correspondingly based on the distance between the target user and the audio device, so that the target user can listen to the audio data played by the audio device at any position without difference, and the auditory perception of the user is improved. That is to say, the position of the target user may be continuously tracked in the process that the audio device is in the working state, the real-time distance between the target user and the audio device is obtained, and then the playing volume of the audio device is adjusted according to the real-time distance, and for a specific implementation of adjusting the playing volume according to the distance, reference may be made to the related descriptions above.
Optionally, before the tracking the position of the target user, the method further includes:
receiving voice information of a user;
extracting the voiceprint features of the user from the voice information, and matching the voiceprint features of the user with preset voiceprint features;
and under the condition that the matching is successful, determining that the user is a target user, and executing the step of tracking the position of the target user.
In this embodiment, when the audio device just enters the operating state, the user may be authenticated through the voice information of the user, and when the authentication is passed, the user may be tracked as a target user, and the play volume may be adjusted through the distance between the target user and the audio device.
The voice information of the user can be a voice instruction which is sent by the user and used for indicating to adjust the volume, or can be a voice instruction which is specially used for indicating to start the automatic volume adjustment function; the voice command may be a voice command for waking up the audio device by a user or a voice command for controlling the audio device by the user when the audio device has been determined to turn on the automatic volume adjustment function, or any voice message sent by the user at will when the audio device has been determined to turn on the automatic volume adjustment function.
Therefore, when the user sends the voice instruction, the audio equipment can receive the voice instruction of the user through an audio acquisition module such as a microphone array and enter a volume automatic adjustment function based on the voice instruction; or under the condition that the audio equipment defaults to start the automatic volume adjusting function, the audio equipment is awakened through the voice instruction to enter the automatic volume adjusting function, and the voiceprint characteristics of the user can be further extracted from the voice information sent by the user so as to verify whether the user sending the voice information is the target user with the authority.
Then, based on the received voice information, the voiceprint feature of the user corresponding to the voice information may be extracted from the received voice information, for example, the voiceprint feature of the user may be obtained by extracting Mel-scale frequency Cepstral Coefficients (MFCCs), and different users may be distinguished by the voiceprint feature.
Then, the extracted voiceprint features of the user can be matched with preset voiceprint features to determine whether the user is an authorized user, that is, a target user, the preset voiceprint features can be extracted from voice information pre-entered by an authorized user, that is, a holder or an authorized user of the audio device can pre-enter voice information to perform voiceprint registration, so that whether a sound-producing user has an authority to adjust the volume of the audio device can be identified through voiceprint matching subsequently.
And under the condition that matching is successful, namely the voiceprint features of the user are matched with preset voiceprint features, the user can be determined to be the holder of the audio equipment or a target user with volume adjustment authority, so that the state of tracking the position of the target user can be entered, and the distance between the target user and the audio equipment can be acquired.
And step 102, controlling an audio acquisition module of the audio equipment to receive a first response voice sent by a user after the first inquiry voice is played.
After the audio device sends the first query voice, the user may listen to the query voice and may respond to the first query voice, so that the audio device may determine the user position again, and if the user responds after listening to the first query voice, such as sending the first response voice, the audio acquisition module of the audio device may receive the first response voice sent by the user after playing the first query voice, where the audio acquisition module may be a device with a sound acquisition function, such as a microphone.
The first answering voice may be any voice signal, or may be a voice containing specific information, for example, a nickname information of a user may be added to the first answering voice, so that the audio device authenticates the user who sends the answering voice according to the nickname of the user in the answering voice, and determines whether the user is the target user.
Optionally, after the step 101, the method further includes:
controlling the audio playing module to play a second inquiry voice under the condition that the audio acquisition module does not receive the response voice within a first time interval after the first inquiry voice is played;
wherein the first answering voice is the answering voice sent by the user aiming at the second inquiry voice.
In practical applications, after the audio device sends the first query voice, the user may not notice the query voice, or does not respond in time, so that the audio device does not receive the response voice of the user within a first time interval after the playing of the first query voice is finished, and in order to avoid that the user distance cannot be obtained due to the fact that the response voice of the user cannot be obtained under such a situation, and further the volume adjustment cannot be continued, the audio device may send the query voice again at an interval of time after the playing of the first query voice is finished, for example, the audio playing module is controlled to play the second query voice after the interval of the first time interval, where the first time interval may be set according to actual requirements, for example, set to 2s, 3s, and the second query voice may be the same as or different from the first query voice, for example, play "xiao ming", where do you are? Please answer.
Similarly, to ensure that the audio device emits a more targeted query voice, the second query voice may also contain a nickname of the target user to instruct the target user to respond to the query voice, so as to avoid other users from emitting interfering voices.
In this way, the first answering voice is the answering voice sent by the user for the second inquiry voice, and the audio device may redetermine the distance of the user relative to the audio device according to the first answering voice sent by the user after listening to the second inquiry voice, and then adjust the playing volume based on the distance.
And 103, determining the current distance of the target user relative to the audio equipment based on the first response voice.
After receiving a first response voice sent by a user, the target user may be retraced based on the first response voice, specifically, a distance from the target user to the target user may be obtained by combining sound source positioning and distance detection technologies, for example, a direction of the user sending the first response voice with respect to the audio device may be determined by sound source positioning, and then a current distance from the target user with respect to the target user may be detected along the direction, for example, a distance between the target user and the audio device may be measured by an infrared ranging module.
Optionally, the step 103 includes:
determining the direction of a user who sends the first answering voice relative to the audio equipment according to the first answering voice;
controlling a distance detection sensor of the audio equipment to perform distance detection on the object in the direction, and determining the distance between the object closest to the audio equipment and the audio equipment;
and taking the distance between the object closest to the audio equipment and the audio equipment as the current distance of the target user relative to the audio equipment.
In this embodiment, after receiving a first response voice sent by a user, determining a direction of the user sending the first response voice relative to the audio device according to the response voice, for example, determining the direction of the first response voice through sound source positioning, so that the audio device may lock the direction to obtain a position of the user, for example, rotating a camera toward the direction to track the position of the user, thereby obtaining a distance from the user to the user, or sending an infrared detection signal along the direction to detect the distance from the user to the user. That is, the distance detection sensor for controlling the audio device performs distance detection on the object in the direction, determines the distance between the object in the direction and the audio device, and when a plurality of objects exist in the direction, the distance between the object closest to the audio device and the audio device can be used as the current distance between the target user and the audio device, so that the problem that the audio device abandons detection of the user distance due to detection of a plurality of objects, and further volume adjustment is interrupted is avoided. The distance detection sensor may be a sensing device having a distance measurement function, such as an infrared distance sensor or an ultrasonic distance sensor.
Therefore, the distance between the target user and the audio equipment is obtained again based on the response voice sent by the user, so that the continuous adjustment of the volume of the audio equipment can be ensured, and the volume adjusting effect is improved.
Further, before the distance between the object closest to the audio device and the audio device is taken as the current distance of the target user relative to the audio device, the method further comprises:
performing biometric detection on the object closest to the audio device;
if the object closest to the audio device is a living being, the step of taking the distance between the object closest to the audio device and the audio device as the current distance of the target user relative to the audio device is executed.
In this way, in order to save system resources and reduce computation workload, when distance detection is performed on an object in the direction, all objects in the direction do not need to be detected, but only biological feature detection is performed on the object in the direction, this way only needs to detect when to identify one object, that is, only needs to detect and identify the object closest to the audio device, that is, detect whether the object closest to the audio device is a living thing, and specifically, whether biological feature detection is performed through a biological feature detection sensor, or whether the object moves, whether a face image is provided, whether an object contour conforms to a human image, whether the object conforms to a human infrared feature, and the like.
And if the object closest to the audio equipment is detected to be a living being, the living being can be judged to be the target user, so that the distance between the object closest to the audio equipment and the audio equipment is determined as the current distance between the target user and the audio equipment, and the audio equipment is enabled to adjust the playing volume according to the distance.
Optionally, after the step 102, the method further includes:
determining whether the user sending the first answering voice is the target user or not according to the first answering voice;
if the user who sends the first response voice is the target user, the step 103 is executed.
That is to say, in this embodiment, in order to determine the distance between the target user and the audio device more accurately, the user who sends the first response voice may be verified, so as to ensure that the current distance between the user and the audio device is determined based on the first response voice only when the user is the target user, and further ensure that the play volume adjusted according to the distance can be adapted to the current position of the target user.
In one manner, it may be determined whether the user is the target user according to a voiceprint feature of the user who utters the first answering voice, and specifically, before the step 101, that is, before acquiring the tracking status of the target user, the method further includes:
determining the voiceprint characteristics of the target user according to the voice emitted by the target user in the voice interaction with the audio equipment;
the determining whether the user who sends the first answering voice is the target user according to the first answering voice comprises the following steps:
determining the voiceprint characteristics of the user who sends the first answering voice according to the first answering voice;
and comparing the voiceprint characteristics of the user who sends the first answering voice with the voiceprint characteristics of the target user, and determining whether the user who sends the first answering voice is the target user.
In this manner, the voiceprint feature of the target user may be extracted in advance from the process that the target user performs voice interaction with the audio device, that is, the voiceprint feature of the target user may be extracted from the interactive voice sent from the target user to the audio device, where the voice interaction may include at least one of voice registration, voice wake-up of the audio device, and voice control of the volume of the audio device.
For example, when the target user performs voice registration, the voiceprint feature of the target user may be extracted from the registration voice input by the user and stored, or when the target user inputs a wake-up voice to wake up the audio device, the voiceprint feature of the target user may be extracted from the wake-up voice and recorded, or when the target user issues a voice instruction to the audio device to control the volume of the audio device, the voiceprint feature of the target user may be extracted from the voice instruction and recorded.
Thus, after receiving the first response voice sent by the user, the voiceprint feature of the user sending the first response voice can be extracted from the first response voice, and comparing the voiceprint feature of the user who sends the first response voice with the previously acquired voiceprint feature of the target user, and determining whether the user who uttered the first response voice is the target user, specifically, in the case where the voiceprint feature of the user who uttered the first reply voice matches the voiceprint feature of the target user, it may be determined that the user who uttered the first reply voice is the target user, and in the case that the voiceprint feature of the user who uttered the first reply voice does not match the voiceprint feature of the target user, it may be determined that the user who uttered the first reply voice is not the target user.
Therefore, in this manner, by comparing the voiceprint features, it can be determined more accurately whether the user who utters the first response voice is the target user, and further, it can be determined whether to perform the step of determining the distance between the target user and the audio device based on the first response voice.
In another mode, determining whether the user who utters the first answering voice is the target user according to the nickname information of the user included in the first answering voice, specifically, determining whether the user who utters the first answering voice is the target user according to the first answering voice may include:
identifying the first answering voice, and determining whether the first answering voice contains a nickname of a user who sends the first answering voice;
if the first answering voice contains the nickname of the user who sends the first answering voice, comparing the nickname of the user who sends the first answering voice with the nickname of the target user, and determining whether the user who sends the first answering voice is the target user.
In this manner, after the first answering voice is received, the voice information included in the first answering voice may be recognized first by a voice recognition technology, and it is determined whether the user nickname information is included therein, and if the information in the first answering voice is recognized as "my is mingming, i is here", it may be determined that the user nickname "mingming" is included therein.
If the first answering voice is identified to contain the user nickname, the user nickname can be compared with the nickname of the target user, so that whether the user sending the first answering voice is the target user is determined according to the comparison result, specifically, under the condition that the user nickname contained in the first answering voice is matched with the nickname of the target user, the user sending the first answering voice can be determined to be the target user, and under the condition that the user nickname contained in the first answering voice is not matched with the nickname of the target user, the user sending the first answering voice can be determined not to be the target user.
The nickname of the target user may be obtained from a user nickname included in the first query voice, or may be obtained from pre-stored nickname information of the target user, for example, a nickname entered by the target user at the time of voice registration may be obtained.
In this way, in this manner, by comparing the nicknames of the users, it can be determined more accurately whether the user who utters the first answering voice is the target user, and further, it can be determined whether to perform the step of determining the distance between the target user and the audio device based on the first answering voice.
And 104, adjusting the playing volume of the audio equipment according to the current distance between the target user and the audio equipment.
After the current distance between the target user and the audio device is obtained, the playing volume of the audio device can be adjusted adaptively according to the distance, specifically, the audio device can pre-establish a corresponding relation table between the distance and the volume, so that in the adjusting process, the target volume corresponding to the current distance can be obtained through table lookup, and the playing volume of the audio device is adjusted to the target volume.
In order to ensure that a user can listen to the audio data played by the audio device at any position without distinction and improve the auditory sense of the user, the relationship between the playing volume of the audio device and the distance may be set as follows: the playing volume is positively correlated with the distance. For example, if it is detected that the distance between the target user and the audio device is increased, the playing volume of the audio device is adjusted to be larger correspondingly, and if it is detected that the distance between the target user and the audio device is decreased, the playing volume of the audio device is adjusted to be smaller correspondingly.
Therefore, under the condition that the position of the target user fails to be tracked, the response voice of the user is obtained by sending out the inquiry voice, the position of the target user is relocated based on the response voice of the user, and finally the playing volume of the audio equipment can be timely adjusted according to the distance between the target user and the audio equipment, so that a better volume adjusting effect is ensured.
Optionally, after the step 104, the method further includes:
extracting user sound data other than the played audio data of the audio device from the ambient sound data;
matching the voiceprint features in the user voice data with preset voiceprint features;
under the condition that matching is successful, determining a first distance between a target user corresponding to the user sound data and the audio equipment according to the user sound data;
and adjusting the playing volume of the audio equipment according to the first distance.
Since the user position is not always fixed, in order to ensure that the playing volume of the audio device can be dynamically adjusted according to the real-time position of the user, the environmental sound data can be continuously analyzed to extract the user sound data except the playing audio data of the audio device, corresponding voiceprint features can be extracted from the user sound data, and the voiceprint features are matched with preset voiceprint features to verify whether the user sound data are sound data emitted by a target user with authority, wherein the preset voiceprint features can be extracted from voice information which is pre-recorded by an authority user.
If the matching is successful, it can be determined that the user sound data is emitted by the target user, so that a first distance between the target user corresponding to the current user sound data and the audio device can be obtained by locating the sound emitting position of the sound data, and the playing volume of the audio device is adjusted according to the first distance.
Therefore, the real-time position of the target user can be updated by monitoring the sound data of the target user in real time, and then the playing volume of the audio equipment can be adaptively adjusted based on the real-time position of the target user, so that the playing volume of the audio equipment is ensured to be adaptive to the position of the target user, and the hearing experience of the user is guaranteed.
Optionally, after the step 104, the method further includes:
continuing to track the target user to obtain a second distance of the target user relative to the audio device in real time;
and adjusting the playing volume of the audio equipment according to the second distance.
In this embodiment, in order to ensure that the playing volume of the audio device can be dynamically adjusted according to the real-time position of the user, the position of the target user may be continuously tracked, for example, the position of the target user is tracked by an infrared detector, so that the real-time distance between the target user and the audio device can be obtained according to the real-time position of the target user, and the playing volume of the audio device may be adaptively adjusted according to the real-time distance, that is, the playing volume of the audio device is adjusted to correspond to the second distance between the target user and the audio device.
Therefore, under the condition that the user does not produce sound, the real-time distance of the target user relative to the audio equipment can be obtained by tracking the position of the target user, and then the playing volume of the audio equipment is adjusted to be matched with the real-time distance, so that good hearing experience of the user is guaranteed.
It should be noted that, while tracking the position of the target user, the ambient sound data may be continuously analyzed, so as to extract the user voice data from the voice data, and can accurately position the target user by combining the voiceprint matching according to the voice data of the target user, in the case where no user voice data is heard, the user's location can be tracked by infrared, while there are multiple users in the vicinity of the audio device, or where there is an occlusion between the audio device and the user, such that the target user cannot be discerned or the user's location tracked, the target user location may be accurately located by listening to the user's voice data, thus, by doubly locating the user location, the distance between the user and the audio equipment can be more accurately and comprehensively obtained, and the adjusted playing volume is further ensured to be more in line with the expectation of the user.
The following takes the smart sound box as an example to illustrate the specific implementation of the embodiment of the present invention, and the following is only one example of the specific implementation of the present invention:
the intelligent sound box can include sound collection module, sound processing module, infrared tracking ranging module, data storage module and voiceprint registration module, wherein, sound collection module can use the microphone array to gather environment speech signal, send the speech signal who gathers to sound processing module, sound processing module then carries out voiceprint recognition, sound localization and speech recognition to it, infrared tracking ranging module tracks the target object and removes, and real-time measurement and target object's distance, data storage module storage user voiceprint information.
Firstly, a user can register own voiceprint information through the voiceprint registration module and input corresponding nickname information, and the voiceprint information and the nickname information are stored in the data storage module.
The user sends a voice instruction for opening the automatic volume adjustment function of the intelligent sound box, the voice processing module identifies the voice instruction, positions and distances between the user and the intelligent sound box, meanwhile, voiceprint information of the user is stored in the data storage module and matched with a voiceprint registered by the user, and under the condition that matching is successful, the nickname of the user is obtained.
And the intelligent sound box adjusts the playing volume according to the distance between the user and the sound box and the mapping relation between the preset distance and the volume.
After the intelligent sound box is located out of the position of the user, the position of the user is tracked through the infrared tracking ranging module, the distance between the user and the intelligent sound box is continuously obtained, and playing volume is adjusted in real time according to the distance.
Meanwhile, the intelligent sound box can continuously analyze the voiceprint information of the sound data in the environment and match the voiceprint information with the stored voiceprint information, and if the matching is successful, the position and the distance of the user are located through the sound data at the moment, so that the playing volume is adjusted according to the distance.
When the infrared tracking ranging module cannot acquire infrared information of a user due to the fact that shielding exists between the user and the intelligent sound box, or a plurality of users exist near the intelligent sound box, so that when the acquired user position information is changed drastically in a short time, for example, the moving distance exceeds 1 meter in 100 milliseconds, the system can consider that positioning fails, and under the condition, the intelligent sound box can send out a voice inquiry signal according to a nickname of the user obtained before, such as' Xiaoming, where are you? After the user hears the signal, a response signal is made, the intelligent sound box can acquire the position and the distance of the user according to the response signal, the infrared detection tracking ranging module can also track the position of the user again, and then the playing volume can be continuously adjusted according to the position of the user.
