All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
The embodiment of the application provides a delay detection method, a delay detection device, electronic equipment and a computer readable storage medium. Specifically, the embodiment of the application provides a delay detection device suitable for electronic equipment, and the terminal equipment includes but is not limited to desktop computers, notebook computers, tablet computers or mobile phones and other equipment.
Referring to fig. 1, fig. 1 is a schematic view of a scenario in which a terminal device performs the delay detection method according to the embodiment of the present application, where a specific execution procedure of the terminal device performing the delay detection method is as follows:
the terminal equipment 10 collects the audio played by the audio playing equipment 11 when the Bluetooth equipment 12 is not connected through a microphone to obtain a first test audio, and collects the audio played by the audio playing equipment 11 when the Bluetooth equipment 12 is connected through the microphone of the terminal equipment 10 to obtain a second test audio;

then, a Bluetooth audio delay is determined based on the first audio delay and the second audio delay.
In summary, in the embodiment of the present application, the first audio delay is calculated when the bluetooth device is not connected, so that the first audio delay represents the audio delay of the audio playing device, and the second delay is calculated when the bluetooth device is connected, so that the second audio delay represents the audio delay of the audio playing device and is based on the sum of the delays when the bluetooth device is connected, and therefore, after the first audio delay and the second audio delay are calculated, the bluetooth audio delay representing bluetooth can be calculated through the first audio delay and the second audio delay.
The Bluetooth audio delay can be calculated and obtained only by collecting test audio when the Bluetooth equipment is connected or not connected, so that the complexity of Bluetooth audio delay detection is reduced.
The following will describe in detail. It should be noted that the following description order of embodiments is not a limitation of the priority order of embodiments.
Referring to fig. 2, fig. 2 is a flow chart of a delay detection method according to an embodiment of the present application. The specific flow of the delay detection method is as follows:
101. the method comprises the steps of obtaining first test audio and second test audio, wherein the first test audio is test audio collected when a Bluetooth device is not connected, and the second test audio is test audio collected when the Bluetooth device is connected.
It is understood that the first test audio and the second test audio may be collected by the audio playing device after playing the audio, for example, the audio is played by the audio playing device and recorded by the microphone. The audio playing device can be a mobile phone, a tablet personal computer and other devices.
The audio played by the audio playing device can be audio with a specific frequency spectrum, or can be any audio applied in the audio playing device.
It can be understood that the unconnected bluetooth device means that the audio playing device is not connected with the bluetooth device, and at this time, the audio playing device is in an externally-placed state, that is, the loudspeaker of the audio playing device is directly utilized to play audio; connect bluetooth device to indicate that audio playback device and bluetooth device establish the connection, at this moment, through bluetooth device play audio frequency outward, promptly, need just can hear the audio frequency that audio playback device broadcast through bluetooth device, corresponding, microphone and phoenix need gather the output of this bluetooth device, just can record and obtain second test audio.
It will be appreciated that by the acquisition of the second test audio and the first test audio with and without the bluetooth device connected, the bluetooth audio delay is facilitated by the calculation of the first test audio and the second test audio.
102. And determining a first trigger time and a first playing time according to the first test audio, and determining a second trigger time and a second playing time according to the second test audio.
It should be noted that, the first trigger time and the first playing time are the times in the first test audio, and specifically, the first trigger time is the time for triggering audio playing, for example, when the audio playing is controlled by clicking the screen of the audio playing device, the time for clicking the screen of the audio playing device is the first trigger time; when the mouse is used for driving the cursor to control the audio playing in the audio playing device, the clicking time of the mouse is the first triggering time.
The first playing time may be a time when the audio starts playing, or may be a time when the audio ends playing. In this embodiment, the audio playing start time is taken as an example for explanation, and the case where the first playing time is the audio playing end time can be understood by referring to the description.
The first test audio and the second test audio are the recorded results of the two tests, and the second trigger time and the second playing time are the times in the second test audio, so the second trigger time can be understood by referring to the first trigger time, and the second playing time can also be understood based on the first playing time.
It can be appreciated that by acquiring the first trigger time and the first play time of the first test audio, calculation of the first audio delay corresponding to the first test audio is facilitated; the second trigger time and the second playing time of the second test audio are acquired, so that calculation of second audio delay corresponding to the second test audio is facilitated.
103. Determining a first audio delay according to the first trigger time and the first play time, and determining a second audio delay according to the second trigger time and the second play time.
It will be appreciated that the first playing time reflects the time at which the audio is actually played, the first trigger time is the time at which the audio is expected to start playing, and the first audio delay when the bluetooth device is not connected can be obtained by the time difference between the first trigger time and the second playing time.
Correspondingly, by calculating the difference between the second trigger time and the second playing time, a second audio delay representing the connection of the bluetooth device can be obtained, wherein the second audio delay comprises the audio delay (first audio delay) of the audio playing device itself and also comprises the delay corresponding to bluetooth.
104. And determining Bluetooth audio delay according to the first audio delay and the second audio delay.
Since the second audio delay includes both the first audio delay and the delay corresponding to bluetooth, a bluetooth audio delay characterizing the bluetooth delay may be obtained by a time difference between the first audio delay and the second audio delay.
To sum up, the embodiment of the application only needs to collect test audio when connected and unconnected with the Bluetooth equipment, and can calculate and obtain Bluetooth audio delay, so that complexity of Bluetooth audio delay detection is reduced.
Optionally, since the test audio corresponds to an audio waveform, the trigger time and the play time may be calculated using the audio waveform, for example, the trigger audio waveform of the trigger operation and the play audio waveform in response to the trigger operation are identified from the audio waveform corresponding to the test audio, and then the trigger time is obtained by the trigger audio waveform and the play time is obtained by the play audio waveform, that is, optionally, in some embodiments of the present application, the step of "determining the first trigger time and the first play time according to the first test audio and determining the second trigger time and the second play time according to the second test audio" includes:
Identifying a first trigger audio waveform of a trigger operation according to a first audio waveform corresponding to the first test audio, and identifying a first play audio waveform responding to the trigger operation, and acquiring a first trigger time of the first trigger audio waveform and a first play time corresponding to the first play audio waveform;
and identifying a second trigger audio waveform of the trigger operation according to the second audio waveform corresponding to the second test audio, and identifying a second play audio waveform responding to the trigger operation, and acquiring a second trigger time of the second trigger audio waveform and a second play time corresponding to the second play audio waveform.
The triggering operation is an operation of triggering audio to start playing, and the triggering operation can be a screen clicking operation or a clicking operation by using a mouse.
It is understood that the first trigger audio waveform and the first played audio waveform are audio waveforms in the first audio waveform and the second trigger audio waveform and the second played audio waveform are audio waveforms in the second audio waveform. The audio waveform is a form of electro-acoustic oscillation that describes the frequency information and energy spectrum of a piece of audio. Audio waveforms may be used to visualize music and other sounds, make the sounds easier to analyze and process, and may be used to detect different types of features.
The waveforms corresponding to different audio frequencies are different, so that the first trigger time can be obtained according to the first trigger audio waveform after the first trigger audio waveform is identified, and the first play time can be obtained according to the first play audio waveform after the first play audio waveform is identified. Similarly, the second trigger time and the second play time may also be obtained from the corresponding second trigger audio waveform and second play audio waveform.
It will be appreciated that the principle or steps of identifying the first trigger audio waveform and the first played audio waveform from the first audio waveform and the second trigger audio waveform and the second played audio waveform from the second audio waveform may be identical, and that the principle or steps of identifying the first trigger audio waveform and the first played audio waveform may also be identical, and therefore, the description will be given below taking the first trigger audio waveform from the first audio waveform as an example, and the first played audio waveform from the first audio waveform and the second trigger audio waveform and the second played audio waveform from the second audio waveform as references.
Specifically, in the embodiment of the present application, the machine learning model may be used to identify a first trigger audio waveform from the first audio waveforms, that is, optionally, in some embodiments of the present application, the step of "identifying, according to the first audio waveform corresponding to the first test audio, the first trigger audio waveform of the trigger operation" includes:
Determining at least two sub-audio waveforms according to a first audio waveform corresponding to the first test audio;
extracting waveform characteristics of the sub-audio waveform through an audio characteristic extraction model;
and determining a first trigger audio waveform for triggering operation from the sub audio waveforms according to the waveform characteristics.
The sub-audio waveforms are part of the first audio waveforms, and each sub-audio waveform is continuously combined to obtain the first audio waveform, and the sub-audio waveform is formed by wave crests and fold lines on two sides of the wave crests.
In this embodiment of the present application, the audio feature extraction model is a trained machine learning model, and may analyze each sub-audio waveform in the first audio waveform to obtain a waveform feature of each sub-audio waveform. Correspondingly, in the embodiment of the present application, the audio feature extraction model may be an image processing model for an image, and feature extraction is performed on a waveform chart corresponding to the first audio waveform based on the image processing model, so as to obtain waveform features of each sub-audio waveform in the waveform chart. The waveform characteristics may include included angles, heights, etc. of the audio waveform. Correspondingly, the audio feature extraction model may be a classification model or a regression model, and in this embodiment of the present application, the model type and the specific network structure of the model are not limited, and may be selected according to performance, power consumption, and operation simplicity, for example, a YOLOv5 model is selected.
Optionally, whether the audio playing is based on the screen click or the mouse click control, there is a characteristic that the operation time is short, so the audio waveform formed based on the screen click or the audio waveform formed based on the mouse click has a sharp characteristic, therefore, the waveform type of the sub-audio waveform can be determined according to the waveform characteristics, and then the selection of the first trigger audio waveform is performed according to whether the waveform type meets the condition, that is, optionally, in some embodiments of the present application, the step of determining the first trigger audio waveform for triggering the operation from the sub-audio waveforms according to the waveform characteristics includes:
determining the waveform type of the sub-audio waveform according to the waveform characteristics;
if the waveform type meets a first preset condition and the waveform peak value of the sub-audio waveform reaches a peak threshold value, taking the sub-audio waveform as a target waveform;
and determining a first trigger audio waveform from the target waveforms according to the time sequence of the trigger operation and the audio playing.
The waveform type may be determined according to data such as an angle included in the waveform feature, for example, if the angle is smaller than a certain threshold, the audio waveform is considered to be sharp, that is, the waveform type is of a sharp type, and the waveform type accords with the characteristic of the first trigger audio waveform.
The audio frequency before and after the screen click and the mouse click is relatively uniform, for example, the environmental sound is balanced, namely the change of the peak value in the waveform diagram is smaller, and the audio waveform formed by the screen click or the mouse click is more prominent compared with the environmental sound, so that the peak value of the waveform is improved to a certain extent, and the accuracy of the identification of the first triggering audio waveform is improved through the judgment of the peak value. Wherein the peak threshold may be configured according to empirical parameters.
In order to screen out the first trigger audio waveform corresponding to the trigger operation, the sub audio waveform may include a plurality of target waveforms meeting the conditions, and therefore, the filtering may be further performed according to the time sequence of the trigger operation and the audio playing, for example, the sub audio waveform meeting the type conditions and having a time point before is used as the first trigger audio waveform.
Optionally, in this embodiment of the present application, audio waveforms corresponding to multiple triggering operations may be pre-encoded by using an audio feature extraction model, and then, by comparing waveform features of each sub-audio waveform with pre-encoded features in the first audio waveform, the first triggering audio waveform is screened from the first audio waveform, that is, optionally, in some embodiments of the present application, the step of determining, according to the waveform features, the first triggering audio waveform of the triggering operation from the sub-audio waveforms includes:
Calculating the similarity between the waveform characteristics and the pre-coding characteristics, wherein the pre-coding characteristics are obtained by extracting the characteristics of at least two types of triggering audio waveforms in advance;
screening waveform characteristics to be selected from the waveform characteristics according to the similarity;
if at least two waveform characteristics to be selected exist, screening target waveform characteristics from the waveform characteristics to be selected according to the time sequence of triggering operation and audio playing;
and taking the sub-audio waveform corresponding to the target waveform characteristic as a first trigger audio waveform.
It can be understood that the pre-coding feature is obtained by extracting features of audio waveforms corresponding to various triggering operations in advance, and the filtering of the features of the waveforms to be selected, which are in accordance with the triggering operations, in the sub-audio waveforms is realized through the calculation of the feature similarity. For example, a sub-waveform feature in the first audio waveform that has a high similarity (exceeding a similarity threshold) to the pre-coding feature is taken as the waveform feature to be selected.
Correspondingly, if the waveform feature to be selected is one, the sub-audio waveform corresponding to the waveform feature to be selected is directly used as the first trigger audio waveform, if the waveform feature to be selected is a plurality of, the first trigger audio waveform is screened out from the waveform features to be selected according to the time sequence of the trigger operation and the audio playing, for example, the audio waveform with the forefront time point is used as the first trigger audio waveform.
Optionally, in this embodiment of the present application, an audio waveform corresponding to the triggering operation may be collected multiple times, then a clicking waveform curve (or clicking waveform formula) for the triggering operation is fitted through the multiple audio waveforms, and a sub-audio waveform in the first audio waveform is identified based on the clicking waveform curve, so as to screen out the first triggering audio waveform, that is, optionally, in some embodiments of the present application, the step of "identifying the first triggering audio waveform of the triggering operation according to the first audio waveform corresponding to the first test audio" includes:
acquiring a clicking waveform curve, wherein the clicking waveform curve is obtained by fitting an audio waveform based on historical triggering operation;
and taking the sub-audio waveform matched with the clicking waveform curve in the first audio waveform as a first triggering audio waveform.
The click waveform curve is obtained through fitting, so that the rule or characteristic which is met by the audio waveform corresponding to the triggering operation is obtained, and the screening of the sub-audio waveform which accords with the characteristic in the first audio waveform can be realized based on the characteristic.
Optionally, after the first trigger time and the first play time are obtained, the first audio delay may be obtained according to the two time differences, that is, the difference between the first play time and the first trigger time is calculated, so as to obtain the first audio delay.
Correspondingly, the bluetooth audio delay can be obtained according to the time difference between the second audio delay and the first audio delay, that is, the difference between the second audio delay and the first audio delay is calculated to obtain the bluetooth audio delay.
In this embodiment of the present application, the first trigger time and the first play time may be acquired multiple times to obtain multiple first audio delays, and then the final first audio delay is obtained by means of a mean value of the multiple first audio delays, and similarly, the final second audio delay is obtained by means of a mean value.
For example, referring to fig. 3, fig. 3 is a schematic diagram of a first audio waveform obtained when bluetooth is not connected, where the first audio waveform includes a plurality of first audio waveforms, such as N1, N2, N3, and N4, and correspondingly, taking the first audio waveform N1 as an example, a first trigger audio waveform P1 and a first play audio waveform P2 are obtained through recognition, and correspondingly, a first audio delay Dn 1=p2-P1. Then, a final first audio delay is obtained from the average of the first audio delays Dn1, dn2, dn3 and Dn4 of the first audio waveforms N1, N2, N3 and N4.
