Detailed ways

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited by the embodiments set forth herein.

Fig. 1 shows a flow chart of the first embodiment of the method for automatic sound adjustment of the present invention, and the method is executed by an automatic sound adjustment device. As shown in Figure 1, the method includes the following steps:

Step 101: Collect the current physiological indicators of the user in real time.

It should be noted that the automatic sound adjustment method of the present application can be applied to various scenarios, such as movie theaters, concert sites, concert halls and other places. Car playback equipment, etc.

In this embodiment, in order to be suitable for users of different ages, it is necessary to collect the physiological index information of the user to facilitate adjusting the parameters of the sound playback device according to the physiological index of the user, wherein the physiological index is collected by a preset physiological index collector. The acquisition is obtained, for example, when the user wears the headset device, the physiological index collector can be set on the headset, and when the user wears the headset, the physiological index collector of the user can collect the physiological index of the user.

In step 101, in order to effectively adjust the sound heard by the user, it is necessary to collect the current physiological index of the user in real time, and realize the real-time adjustment of the sound heard by the user according to the index data collected in real time.

Step 102: Confirm the target sound attribute data corresponding to the current physiological index based on the pre-stored correspondence between the physiological index and the sound attribute data.

It should be noted that the corresponding relationship between the physiological index and the sound attribute data in this embodiment is obtained by setting the historical sample data acquired in advance. The corresponding relationship between the physiological index and the sound attribute data may be pre-stored in the memory of the sound playback device worn by the user.

In step 102, after obtaining the current physiological index of the user, the target sound attribute data corresponding to the current physiological index can be confirmed by querying the corresponding relationship between the physiological index and the sound attribute data, and the target sound attribute data is the current physiological index Next, the sound properties that best suit the user.

Step 103: Adjust parameters of the sound playback device worn by the user according to the target sound attribute data.

Generally, the user's comfortable sound effects are measured from the user's psychological perception to three attribute indicators of loudness, pitch, and timbre.

In step 103, after obtaining the target sound attribute data, the sound playback parameters of the sound playback device worn by the user can be adjusted according to the target sound attribute data, so as to adjust the three parameters of sound, audio and sound waves, So that the user can hear the sound with better listening experience.

The first embodiment of the present invention obtains the current physiological index of the user in real time, inquires about the sound attribute data most suitable for the user according to the current physiological index of the user, and then adjusts the parameters of the user's sound playback device according to the sound attribute data, thereby It enables users of different age groups to enjoy an auditory experience corresponding to their own physiological indicators, realizes personalized auditory settings for users with different physiological indicators, and improves user experience.

Fig. 2 shows a flow chart of the second embodiment of the method for automatic sound adjustment of the present invention, and the method is executed by an automatic sound adjustment device. As shown in Figure 2, the method includes the following steps:

Step 201: Confirm emotional information contained in the sound content currently played by the sound playback device.

It should be understood that effective emotional resonance can greatly improve the user's experience. For example, when watching a movie, using the emotions contained in the sound to mobilize the user's emotions to resonate with the emotions in the movie can greatly improve the user's emotions. movie viewing experience. Therefore, in this embodiment, in order to improve the user's listening experience, the emotion contained in the sound content played by the sound playback device can also resonate with the user's voice to improve the user experience. It should be noted that the audio content refers to text content, not audio information, and emotional information contained in the audio content can be obtained by analyzing the audio content.

In step 201, when the sound playing device plays the sound, the emotional information contained in the sound is calculated according to the content of the played sound. The emotion information is the emotion that the user is expected to experience in the played sound.

Step 202: Predict according to the emotional information to obtain the predicted mental state of the user.

In step S202, use the emotional information to predict the mental state that the user should have. For example, when the emotional information in the voice is happiness, the predicted response of the user's mental state should be excited, happy, happy, etc.

Step 203 : Judging the user's mental state based on the preset emotion algorithm in combination with the current physiological index, and confirming the user's actual mental state.

It should be noted that the preset emotion algorithm is preset. At present, the theory of "affective computing" has been widely studied, which can realize the relationship mapping between mental state and physiological indicators through a variety of different algorithms, such as particle swarm algorithm, K-nearest neighbor algorithm, discriminant function analysis method, Marquardt reverse Propagation and support vector machine algorithms, etc. In this embodiment, the preset emotion algorithm may be implemented based on any one of the above algorithms.

In step 203, after the predicted mental state of the user is obtained, the actual mental state of the user is calculated by using the collected current physiological index of the user in combination with a preset preset emotion algorithm.

Step 204: Compare the predicted mental state with the actual mental state, and adjust the parameters of the sound playback device according to the comparison result.

In step 204, the predicted mental state is the mental state expected after the user hears the currently playing sound. By comparing the predicted mental state with the current actual mental state of the user, it can be confirmed that the user is listening to the sound playing device playing After the sound, whether there is a corresponding emotion, when the user does not generate the corresponding emotion, it means that the user's emotion has not been well mobilized and does not resonate with the content of the sound. At this time, you can adjust the parameters of the sound playback device. Improve the emotional appeal of the sound played to the user.

In this embodiment, in order to improve the user's experience, it is also necessary to consider the resonance of the user's emotion and the emotion of the sound content, and the method of adjusting the parameters of the sound playback device through physiological indicators has a good use experience in some scenarios, such as operator, However, this adjustment method fails to effectively adjust the emotions in a variety of ways, and cannot further improve the user experience. Effective emotional resonance depends on the ability to recognize emotions from auditory stimuli and to respond appropriately These brain regions respond to different emotions in the same way in a given situation, regardless of the sound source, as shown by sensor analysis of physiological indicators, primary and secondary auditory cortex, posterior insula and parietal Activity patterns of lids can predict emotional information from sounds of different sound content, and in addition, experiments have shown that classification accuracy within anterior insula insulation correlates with behavioral measures of empathy, brain regions with emotion-specific patterns that are Prevalent in sounds of different acoustic properties, likewise, people with higher empathy have more distinct neural patterns related to perceived emotion, extending previous knowledge about how the human brain extracts emotional meaning from auditory stimuli, and It enables us to effectively understand and connect with others. Similarly, each individual has different empathy abilities and emotional experiences. It is necessary to effectively adjust their empathy on the basis of not destroying their normal empathy. Excessive generalization of emotions to empathize with sound content is a problem to be solved by this embodiment. Therefore, on this basis, the present embodiment comprehensively determines the user's emotion by combining the data of the user's primary and secondary auditory cortex, the posterior island and the roof. Among them, the user's primary and secondary auditory cortex, posterior insula and tectum, etc. data can be monitored using physiological indicators sensors. After the user's emotion is obtained, it is compared with the predicted emotion predicted according to the sound content, and the sound playback willingness parameter is modified according to the comparison result, so as to improve the possibility of asking the user to empathize with the sound content.

Further, step 204 specifically includes:

1. Confirm the first emotional category set corresponding to the predicted mental state and the second emotional category set corresponding to the actual mental state based on the preset emotional level and emotional direction.

In order to facilitate understanding, the emotional information can be divided into at least two emotional levels, where the first-level emotion is defined as basic emotion or direct emotion, such as happiness, sadness and fear, and the second-level emotion is defined as indirect emotion, such as surprise, Shocked, lamented, depressed, nervous, irritable, etc. Emotion levels are designed to distinguish the influence of emotions. The influence of first-level emotions is greater than that of second-level emotions, and the emotional tolerance of different users is preset to an average level. Further, the multi-sample pre-training can also make the acquired emotional tolerance vary from person to person, and when the emotional influence exceeds the emotional tolerance, the sound attribute adjustment operation can be triggered. Emotional directions include positive emotions, neutral emotions, and negative emotions. Emotional direction is designed to distinguish the sustainable time of emotions, that is, the time that users’ emotions in different directions are allowed to last. Neutral emotions are longer than positive emotions and longer than negative emotions. Same as above, assuming that the emotional endurance time of different users is set to the average level first, the same It can also use multi-sample pre-training to make the obtained emotional endurance time vary from person to person. The actual detection of its emotional duration exceeds its emotional endurance time, which can trigger the sound attribute adjustment operation. When the emotion level and emotion direction are combined, six emotion categories can be obtained, including primary positive emotion, primary negative emotion, primary neutral emotion, secondary positive emotion, secondary negative emotion, and secondary neutral emotion.

Specifically, after the predicted mental state and the actual mental state are obtained, the predicted mental state and the actual mental state are confirmed, thereby obtaining a first emotional category set corresponding to the predicted mental state and a second emotional category set corresponding to the actual mental state. It should be understood that both the first emotion category set and the second emotion category set include at least one emotion category.

2. Determine whether the first emotion category set and the second emotion category set are the same.

Specifically, after the first emotional category set and the second emotional category set are obtained, the emotional categories in the first emotional category set and the second emotional category set are compared one-to-one, so as to confirm whether the two are the same.

3. If yes, confirm that the user has valid positive empathy, and maintain the current parameters of the sound playback device.

Specifically, when the first emotional category set and the second emotional category set are exactly the same, it means that the user has developed effective positive empathy with the sound content at this time, and it is no longer necessary to adjust the sound. Therefore, the sound playback is maintained. The current parameters of the device are not adjusted.

4. If not, confirm that the user has invalid or negative empathy, and adjust the parameters of the sound playback device to reduce the emotional influence and emotional duration of the invalid or negative empathy.

Specifically, when the first emotion category set and the second emotion category set are different or only partially the same, it means that the user has invalid or negative empathy with the sound content at this time, and at this time, it is necessary to adjust the parameters of the sound playback device. Adjust, so that after the user hears the sound, it will stimulate the user's brain positively, so as to reduce the emotional influence and emotional duration of invalid or negative empathy, so that the user can gradually develop positive empathy and improve the user's experience.

Further, in some embodiments, before the user uses the sound playback device to play sound, the user already has a certain emotional state, which will cause an impact when adjusting the user's emotion. Therefore, the confirmation of the user is invalid or negative. Empathy, the steps of adjusting the parameters of the sound playback device to reduce the emotional influence and emotional duration of the invalid or negative empathy, specifically including:

4.1. Acquire the pre-collected initial physiological indicators of the user.

Specifically, when the user starts to use the sound playing device, the initial physiological index of the user is collected.

4.2. Confirm the initial mental state of the user according to the initial physiological index and the preset emotional algorithm, and confirm the third emotional category set corresponding to the initial mental state based on the preset emotional level and emotional direction.

Specifically, after obtaining the initial physiological index, the user's initial mental state can be confirmed by using a preset emotional algorithm, and the corresponding third emotional category set can be confirmed in combination with the preset emotional level and emotional direction.

4.3. Confirm the differentiated emotional category set composed of different emotional categories between the first emotional category set and the second emotional category set.

Specifically, by comparing the first emotional category set and the second emotional category set, a differentiated emotional category set composed of different emotional categories between the two is obtained. For example, the first emotional category set includes: first-level positive emotions , second-level positive emotions, the second emotion category set includes: first-level neutral emotions, second-level neutral emotions, and second-level positive emotions, and the distinguishing emotion category sets include: first-level positive emotions, first-level neutral emotions, and second-level neutral emotions.

4.4. Eliminate the emotion categories that appear in the third emotion category set from the differentiated emotion category set, and use the remaining emotion categories as the target emotion categories for invalid or negative empathy.

Specifically, after obtaining the set of distinct emotional categories, compare it with the third emotional category set, and remove the emotional categories that appear in the third emotional category set, and the remaining emotional categories obtained are the user’s voice Target emotion categories for ineffective or negative empathy generated during playback.

4.5. Adjust the parameters of the sound playback device to reduce the emotional influence and emotional duration of the target emotional category to below the corresponding preset emotional threshold.

It should be noted that the preset emotion threshold includes a preset influence threshold and a preset duration threshold. The purpose of adjusting the parameters of the sound playback device is to make the emotional influence of the target emotion category lower than the preset influence threshold, and to make the emotional duration lower than the preset duration threshold.

Specifically, the parameters of the sound playback device are adjusted for the obtained target emotional category, so that the emotional influence and emotional duration of the target emotional category are reduced to below the corresponding preset emotional threshold, and the effect of this emotional category on the user's emotions is reduced. influences.

On the basis of the first embodiment, the second embodiment of the present invention uses the emotional information in the audio content to predict the predicted mental state that the user should generate, and then compares it with the actual mental state obtained according to the user's physiological indicators. If the user is different, adjust the parameters of the sound playback device, so that the adjusted sound can drive the user's emotions to a greater extent, make the user's emotional feeling stronger, and further improve the user's listening experience.

Further, on the basis of the first embodiment, in other embodiments, in order to prevent the user's initial emotional state from having too great an emotional impact on the user, before step 101, the method further includes:

1. Collect the initial physiological index of the user.

2. Confirm the initial mental state of the user according to the initial physiological index and a preset emotional algorithm.

3. Confirm the fourth emotional category set corresponding to the initial mental state based on the preset emotional level and emotional direction.

4. When the emotional influence of the emotional categories in the fourth emotional category set exceeds a preset perception threshold, prompt the user to adjust his emotions.

In this embodiment, the user's initial emotion is confirmed according to the user's initial physiological index before the user uses the audio playback device to play the sound, and when the user's initial emotion is too strong, the user is prompted to adjust his own emotion, so as to facilitate subsequent users Ability to quickly develop empathy with sound content.

Further, on the basis of the first embodiment, in other embodiments, in order to avoid the user's auditory fatigue and reduce the use experience, it further includes:

1. Acquire the change trend of the user's heart rate and respiratory rate data according to the current physiological index of the user.

2. When it is confirmed that the user is in a fatigued state according to the change trend of the heart rate and the change trend of the breathing frequency data, adjust the parameters of the sound playback device to improve the emotional influence of the sound on the user.

Specifically, after obtaining the user's current physiological indicators, the user's heart rate change trend and respiratory frequency data change trend are extracted from it. When the heart rate change trend and the respiratory frequency data change trend are both in a steady state, it indicates that the user is not aware of the current sound. The sound played by the player produces less feedback and may be in a state of fatigue. In this case, the parameters of the sound playing device can be adjusted to improve the emotional influence of the sound on the user, thereby making the user experience better. In this embodiment, the change trend of the user's heart rate and the change trend of the breathing frequency data are confirmed by the real-time collected physiological indicators of the user, and whether the user is in a fatigued state is confirmed according to the change trend of the heart rate and the change trend of the breathing frequency data, and if so, the sound playback device is adjusted. parameters, and then mobilize the user's emotions, so that the user can continue to maintain a high-quality listening experience.

Further, on the basis of the first embodiment, in order to further improve the user experience, other embodiments further include:

1. Receive a voice adjustment request input by the user;

2. Adjust the parameters of the sound playback device according to the sound adjustment request.

In this embodiment, the parameters of the sound playback device are adjusted according to the personalized requirements put forward by the user to adapt to the personalized pursuit of the user, thereby improving the user experience.
