[0042] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0043] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The present application embodiment provides an audio transmission method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the audio transmission method of the present application.

[0045] In this embodiment, the audio transmission method includes steps S10 to S30:

[0046] Step S10, obtaining an audio transmission scheme in a current audio transmission scenario and scheme information of the current audio transmission scheme;

[0047] In one embodiment, the audio transmission scenario may be, for example, a singing scenario through a car microphone. The audio transmission scheme of such an audio transmission scenario is as follows: Figure 2 As shown, the sound is collected by the acquisition device and transmitted to the output device through relevant interfaces such as HDMI interfaces A1 and A2. Among them, the scheme information of the audio transmission scheme includes the HDMI signal transmission distance and the device hardware information and software setting information of the acquisition device and the output device; among them, the device hardware information includes firmware information and performance information, and the performance information can be the performance information of the device processor or encoder and decoder; the software setting information includes codec standard information and codec algorithm information.

[0048] Step S20, based on the scheme information of the current audio transmission scheme, determining the delay optimization strategy through the delay optimization model, wherein the delay optimization model is obtained based on the historical scheme information before and after delay optimization of the historical audio transmission scheme;

[0049] Step S30, modifying the current audio transmission scheme based on the delay optimization measurement strategy to obtain the latest audio transmission scheme, and performing audio transmission through the latest audio transmission scheme.

[0050] In one embodiment, the scheme information of the current audio transmission scheme is input into the pre-trained delay optimization model, and the delay optimization model is used to infer new scheme information corresponding to the scheme information of the current audio transmission scheme, and further compare the scheme information of the current audio transmission scheme and the new scheme information to obtain a delay optimization measurement strategy, so that the current audio transmission scheme is transformed by the delay optimization measurement strategy, and the latest audio transmission scheme is obtained and audio transmission is performed. For example, in the scheme information of the current audio transmission scheme, the delay optimization model infers that the most likely cause of the delay is that the HDMI signal transmission distance is too long, followed by the output device firmware version is too low, and then the encoding algorithm of the acquisition device is too backward. In this case, the output delay optimization strategy is: the HDMI signal transmission distance can be shortened, the high-quality HDMI cable can be updated, the output device and / or the output device firmware version can be updated, and the input device and / or the input device encoding algorithm can be updated.

[0051] In a feasible implementation manner, before step S20, the process includes:

[0052] Obtaining a first historical scheme before delay optimization of the historical audio transmission scheme, first historical scheme information of the first historical scheme, a second historical scheme after delay optimization, and second historical scheme information of the second historical scheme; wherein the scheme information includes HDMI signal transmission distance and device hardware information and software setting information of the acquisition device and the output device; the device hardware information includes firmware information and performance information; the software setting information includes codec standard information and codec algorithm information;

[0053] A delay optimization model for determining a delay optimization measurement strategy is trained through the first historical solution information of the first historical solution and the second historical solution information of the second historical solution.

[0054] Corresponding to the reasoning and application process of the above-mentioned delay optimization model, in this embodiment, a training and learning process of the delay optimization model is proposed. After obtaining the first historical scheme before delay optimization of the historical audio transmission scheme, the first historical scheme information of the first historical scheme, the second historical scheme after delay optimization, and the second historical scheme information of the second historical scheme, the delay optimization model for determining the delay optimization measurement strategy can be trained through the first historical scheme information of the first historical scheme and the second historical scheme information of the second historical scheme.

[0055] Since the delay optimization model is trained based on the historical scheme information before and after the delay optimization of the historical audio transmission scheme, it has learned the relationship between the historical scheme information before and after the delay optimization during the training phase. Therefore, when it performs reasoning, it can obtain the corresponding delay optimization strategy based on the scheme information of the current audio transmission scheme, that is, the transformation strategy for the scheme information of the current audio transmission scheme. Compared with the current manual optimization method of audio delay that relies on expert experience, it improves the efficiency and accuracy of reducing audio delay.

[0056] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 After step S30, the audio transmission method further includes steps T10 to T20:

[0057] Step T10: obtaining the collection period of the audio collected on the collection device, the standard period of the standard audio on the display device, and the audio transmission delay between the collection device and the output device in the latest audio transmission solution;

[0058] Step T20: Determine the target output time period on the output device according to the acquisition time period, the standard time period and the audio transmission delay.

[0059] It should be noted that in audio transmission scenarios such as singing through a car microphone, in addition to audio acquisition and output devices, there are also display devices that display standard audio such as song-related information such as lyrics.

[0060] In one embodiment, the acquisition device may determine the acquisition time period of the audio collected by it, for example, the audio input time period of a certain word collected is [0.9-2.2] (unit not shown), and the standard time period of the standard audio corresponding to a certain word in the aforementioned acquisition time period may be determined based on the audio file of the standard audio on the display device, for example, [1-2], and the output time period of the audio output by the output device may be determined, for example, the audio output time period corresponding to the aforementioned word may be [1.1-2.4].

[0061] Then, the target output time period on the output device is determined based on the acquisition time period, the standard time period and the audio transmission delay. For example, the shorter the standard time period is, the smaller the adjustment of the target output time period compared to the initial output time period. For example, if the standard time period is 1 second, that is, [1-2], then the target output time period can be adjusted from [1.1-2.4] to [1.1-2.2]; if the standard time period is 3 seconds, that is, [30-33], then the target output time period can be adjusted from [30.1-33.8] to [30.1-33.2].

[0062] Therefore, the initial output period on the output device is adaptively adjusted according to the size of the audio transmission delay, so as to obtain the best audio transmission effect under the audio transmission delay. In other words, a better sound output effect that is closer to the standard audio can be obtained, thereby increasing the frequency and stickiness of use of the acquisition device and output device.

[0063] In a feasible implementation manner, the step T20 includes:

[0064] The audio transmission delay is superimposed on the acquisition period to obtain the initial output period;

[0065] Determine the time difference between the acquisition period and the standard period, and the time ratio coefficient between the time difference and the audio transmission delay;

[0066] If the time proportion coefficient is less than the preset adjustment coefficient, the initial output period is adjusted to obtain a target output period on the output device.

[0067] In this embodiment, a new method for adjusting the initial output period on the output device based on the acquisition period, the standard period and the audio transmission delay is proposed, also with the goal of obtaining a better sound output effect that is closer to the standard audio.

[0068] In one embodiment, the audio input period of a certain word collected during the acquisition period is [0.9-2.2], the standard period of a certain word corresponding to the aforementioned acquisition period in the standard audio is [1-2], and the audio output period corresponding to the aforementioned word is [1.1-2.4]. At this time, the time difference between the acquisition period and the standard period is (1-0.9) + (2.2-2) = 0.3, and the time ratio coefficient between the time difference and the audio transmission delay (0.2) is 0.3 / 0.2 = 1.5. If the time ratio coefficient is greater than the preset adjustment coefficient, it means that the current audio input period is significantly different from the standard period. At this time, if the output period is adjusted, it may cause distortion of the output audio, that is, the time length difference between the output audio and the collected audio is relatively large, resulting in a decrease in the audio sense. Therefore, only when the time ratio coefficient is less than the preset adjustment coefficient, that is, when the adjustment of the output period has little effect on the final sense of hearing, the initial output period is adjusted to obtain the target output period on the output device.

[0069] In a feasible implementation manner, the step of adjusting the initial output period includes:

[0070] Determine the audio style of the audio captured on the capture device;

[0071] If the audio style is close to the radical style, the duration of the initial output period is reduced by a first proportional factor;

[0072] If the audio style is close to a calm style, the duration of the initial output period is reduced by a second proportional factor, wherein the first proportional factor is greater than the second proportional factor.

[0073] When adjusting the initial output period, the audio style of the audio collected on the acquisition device can be determined by the audio content, such as radical styles such as rock or heavy metal, or calm styles such as folk and country music. Among them, the audio style corresponding to the audio content can be determined by the style recognition model. Further, if the audio style of the audio collected on the acquisition device, or the audio style directly determined by the current standard audio, is close to the radical style, the duration of the initial output period is reduced by a first proportional factor; if the audio style of the audio collected on the acquisition device, or the audio style directly determined by the current standard audio, is close to the calm style, the duration of the initial output period is reduced by a second proportional factor.

[0074] In one embodiment, the first proportional factor 0.9 is greater than the second proportional factor 0.8. The starting time point of the initial output period can be fixed and the end time point of the initial output period can be changed. The more aggressive, the larger the first proportional factor, and the calmer, the smaller the second proportional factor. Different proportional factors are used to match the corresponding audio style.

[0075] In one embodiment, the audio input period of a certain word collected during the acquisition period is [0.9-2.2], the standard period of a certain word corresponding to the aforementioned acquisition period in the standard audio is [1-2], and the audio output period corresponding to the aforementioned certain word is [1.1-2.4]. If the audio style of the audio is close to the radical style, the length of the initial output period is reduced by the first proportional factor to [1.1-2.4*0.9]. The more radical, the closer the first proportional factor is to the upper limit 1; if the audio style of the audio is close to the calm style, the length of the initial output period is reduced by the second proportional factor to [1.1-2.4*0.8]. The calmer, the closer the second proportional factor is to the lower limit 0.7.

[0076] In a feasible implementation manner, the step of adjusting the initial output period includes:

[0077] The duration of the initial output period and / or the start and end points of the initial output period are adjusted through a preset adjustment model, wherein the preset adjustment model is trained based on historical standard periods, historical output periods and historical scores of historical standard audio.

[0078] When adjusting the initial output period, a preset adjustment model can also be trained based on the historical standard period, historical output period, and historical score of the historical standard audio, and the adjustment model can be used to learn the user score after adjusting the output period with reference to the standard period of the standard audio, that is, how to adjust the output period with reference to the standard period of the standard audio to obtain a higher user score recognized by the user. In this way, in actual applications, the duration of the initial output period and / or the start and end points of the initial output period are adjusted by the preset adjustment model to obtain the target output period on the output device.

[0079] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the audio transmission method of the present application.
