Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "in response to a determination" depending on the context.

The audio output devices currently used in terminal devices such as televisions, computers, mobile phones and projectors, besides their own speakers, also include external power amplifiers and speakers connected in a wired manner by ARC (Audio Return Channel, audio feedback channel) or SPDIF (Sony/PHILIPS DIGITAL INTERFACE, an audio digital interface), and audio output devices such as speakers connected in a wireless manner by BT (BlueTooth device) or Wi-Fi. Compared with the loudspeaker of the terminal equipment, the external audio output equipment can introduce some delay due to the existence of communication transmission distance, data format conversion and other reasons, so that the time difference exists between the sound played by the external audio output equipment and the sound or picture played by the terminal equipment. The existence of the delay can influence the audio/video synchronization or the synchronous playing of multiple devices, so that the user experience is influenced, and a method for adjusting the audio output delay is needed.

The current methods for adjusting audio output delay mainly include two methods:

One method is to add a fixed delay on the terminal device side, for example, for the case of externally connecting a bluetooth speaker to the terminal device, the delay of most bluetooth speakers can be counted, for example, 200ms, and the delay is used as the fixed delay to be set when the terminal device plays.

However, since the fixed delay is only a statistical probability result, the delay for many devices is not accurate. If the actual delay of a certain bluetooth speaker is only 150ms, an error of 50ms will occur with 200ms as the fixed delay. When the bluetooth speaker outputs audio simultaneously with the terminal device, 50ms may already cause a distinction in the sense of hearing by the human ear. The delay of the Bluetooth sound box is also changed and is not a fixed value under the influence of environmental factors such as distance, position and the like and the factors of the Bluetooth sound box, so that the audio output delay cannot be well regulated by adopting the method of adding the fixed delay.

Another method is to provide the user with an interface that can set the delay, and the user can manually set the delay.

However, the accuracy of manual setting is not high and, after setting, resetting is required if the device is replaced. In addition, even if the same audio output device is affected by a plurality of factors such as distance, position and the like, and device self factors, the delay of the device is a floating range and is not a fixed value every time, and the method cannot well adjust the audio output delay.

Based on the above, the present disclosure provides at least one delay adjustment method to effectively automatically adjust the delay of the device according to the audio signal actually played by the device.

As shown in fig. 1, fig. 1 is a flowchart of a delay adjustment method according to at least one embodiment of the present disclosure, where the method may be used in a terminal device, and includes the following steps:

In step 102, a target audio signal is acquired.

The target audio signal is a signal representing a mechanical wave, and may be a regular signal, i.e., a continuously varying analog signal such as music and voice, or an irregular signal such as noise. The target audio signal may be any type of signal, such as a speech segment containing fixed text, a sound with some fixed frequency, or a specified music segment. In some examples, signals other than periodically repeated audio signals may be selected to avoid the inability to determine the delay time in subsequent calculations due to just a few cycles between the target audio signals with time differences.

In this step, the target audio signal may be a target audio signal stored in advance in the reading terminal device, or may be a target audio signal sent by the receiving user or the server, which is not limited in the specific manner of obtaining the target audio signal in this embodiment.

In step 104, the target audio signal is output, so that the target audio signal is played through the first audio output device of the terminal device and the second audio output device externally connected with the terminal device.

The target audio signal needs to be output through the audio interface of the terminal equipment so as to be output to the first audio output equipment of the terminal equipment connected with the audio interface and the external second audio output equipment for playing. For example, the television outputs a target audio signal to play the target audio signal simultaneously through a speaker of the television and a bluetooth speaker connected with bluetooth, or outputs the target audio signal through a speaker of the television and an audio device externally connected through an HDMI (High Definition Multimedia Interface, high-definition multimedia interface) ARC interface.

The number of the second audio output devices externally connected with the terminal device can be one or a plurality of the second audio output devices.

In step 106, a delay time is obtained, where the delay time is determined according to a time difference between the target audio signals respectively played by the first audio output device and the second audio output device.

When the first audio output device and the second audio output device respectively play the target audio signals, the target audio signals played by the second audio output device are slower than the target audio signals played by the first audio output device, namely, a time difference exists between the first audio output device and the second audio output device, and the time difference is the time delay duration to be acquired in the step. The delay time can be used for adjusting the played audio and video of the terminal equipment and the audio output equipment so as to synchronize the played audio and video.

The method of obtaining the delay time is not limited in this embodiment, for example, the played target audio signal may be recorded by a recording device of the terminal device itself and the delay time may be obtained by calculating, or the delay time calculated by other devices may be received by the terminal device.

In step 108, delay adjustment is performed according to the delay time length.

For example, when the external second audio output device is one, the delay time is slower than that of the first audio output device, and when delay adjustment is performed, the playing time of the audio played by the terminal device side can be increased by the delay time, so that the playing time of the audio played by the first audio output device is later than the original playing time, and thus, the audio played by the second audio output device is kept synchronous, and if the terminal device also has the function of playing video, the time of the picture played by the terminal device side can be delayed by the delay time, so that the video playing and the audio playing of the second audio output device are kept synchronous.

For example, when the number of the external second audio output devices is greater than the first number, the previous step will obtain a plurality of delay time periods, that is, time differences between the plurality of second audio output devices and the first audio output device, and at this time, the playing time of the other second audio output devices and the first audio output device may be adjusted based on the second audio output device with the largest delay time period.

According to the delay adjusting method, the target audio signals are played simultaneously through the audio output equipment of the terminal equipment and the external audio output equipment, so that the delay time between the equipment can be determined through the time difference between the target audio signals during playing, the audio output delay of the equipment can be dynamically obtained, the delay setting can be automatically completed, the delay adjusting method can be applied to any equipment with an audio playing function, the actual delay of each equipment can be adjusted when the delay caused by the fact that the equipment is located at different positions or other reasons floats, and inconvenience brought by manual adjustment is avoided.

Fig. 2 is a flow chart of yet another delay adjustment method, shown in at least one embodiment of the present disclosure, that may be used with a terminal device, which more fully describes the acquisition process of a delay duration. As shown in fig. 2, the method may include a process, where the same steps as those in the embodiment of fig. 1 are not repeated.

In step 202, a target audio signal is acquired.

A signal that facilitates speech recognition may be preselected as the target audio signal, such as a signal that has fixed features that are easily recognizable. In one example, in order for the delay adjustment not to affect the user's normal use of the terminal device and audio output device, the frequency of the target audio signal may be outside the range of the human ear hearing frequency, so that the delay is automatically adjusted without being perceived by the user, resulting in a better user experience.

In step 204, the target audio signal is output, so that the target audio signal is played through the first audio output device of the terminal device and the second audio output device externally connected to the terminal device.

In step 206, a recording containing the target audio signal played by the first audio output device and the second audio output device simultaneously is obtained.

The present embodiment is not limited to a specific manner of acquiring a recording containing a target audio signal that is played by both the first audio output device and the second audio output device.

In one example, when the terminal device itself is provided with the first recording device, the first audio output device and the second audio output device may record the target audio signal by using the first recording device of the terminal device itself, so as to obtain the recording.

For example, when the terminal device is a television, the television is provided with a far-field voice recording device, and can record target audio signals played by surrounding first audio output devices and second audio output devices to obtain a record. For example, when the terminal device is a mobile phone, the mobile phone is provided with a microphone, and can record target audio signals played by the first audio output device and the second audio output device around the mobile phone, so as to obtain a record.

Or in another example, the recording sent by the second recording device outside the terminal device may be received, where the recording is obtained by the second recording device recording the target audio signal and playing the target audio signal by the first audio output device and the second audio output device at the same time.

The second recording device is located near the terminal device, for example, may be located at the second audio output device, or may be located at another device having a recording function. For example, in order to make the adjustment of the delay more suitable for the actual use of the user, the recording device nearest to the user may be used to record the sound, so as to obtain the recording, for example, the recording is performed through a mobile phone used by the user, so that, after the delay is adjusted, the sound played by the first audio output device and the second audio output device can be simultaneously transferred to the ears of the user.

In step 208, the recorded audio is uploaded to a speech processing device, so that the speech processing device determines a delay time according to a time difference between the target audio signals respectively played by the first audio output device and the second audio output device.

The voice processing device may be a device where the intelligent voice system is located, for example, may be located at a cloud end, a mobile phone end of a user, or may be located at a terminal device itself. The intelligent voice system in the voice processing device has voice recognition capability, and the delay time between the target audio signals can be determined according to the record.

For example, the intelligent speech system may identify a plurality of target audio signals played in a recording and may determine a time difference between the plurality of target audio signals. For example, as shown in fig. 3, the speaker and the bluetooth speaker of the television are simultaneously played, and the far-field voice recording device records the content of the speaker and the bluetooth speaker of the television, and the same target audio signals played by the speaker and the bluetooth speaker of the television have a certain time difference. The recorded sound is uploaded to the voice processing device, and the intelligent voice system can recognize two target audio signals and judge the time delay between the two target audio signals.

In step 210, the delay time duration issued by the speech processing device is received.

After determining the time delay time length between the audio devices playing the target audio signals, the intelligent voice system feeds the time delay time length back to the television terminal device, such as a television, and the television can complete corresponding time delay setting accordingly.

In step 212, delay adjustment is performed according to the delay time length.

In one embodiment, the number of the second audio output devices externally connected to the terminal device is a plurality of second audio output devices; the determining a delay time according to a time difference between the target audio signals respectively played by the first audio output device and the second audio output device includes: determining delay time lengths corresponding to a plurality of second audio output devices respectively according to a plurality of time differences between the target audio signals respectively played by the first audio output device and the plurality of second audio output devices;

The time delay adjustment according to the time delay time length comprises the following steps: and according to the delay time lengths, carrying out delay adjustment on the terminal equipment and the second audio equipment.

When the number of the second audio output devices externally connected with the terminal device is a plurality of, the playing time of other second audio output devices and the playing time of the first audio output device are adjusted by taking the second audio output device with the largest time delay time length as a reference. For example, if A, B, C are respectively three external second audio output devices, the corresponding delay time periods are a, b, and c, where a > b > c, when performing delay adjustment, the playing time of the first audio output device may be delayed by the maximum delay time period a, the playing time of the second audio output device b may be delayed by a-b, and the playing time of the second audio output device c may be delayed by a-c. If the terminal device also has the function of playing video, the time of playing the picture at the terminal device side can be delayed by the maximum delay time length a.

In one embodiment, the acquiring the delay time length includes: acquiring a recording containing the target audio signals played by the first audio output device and the second audio output device at the same time; and locally identifying the time difference between the target audio signals respectively played by the first audio output device and the second audio output device in the recording, and determining the time delay duration.

Besides the determination of the delay time length by the voice processing device, the determination of the delay time length can also be performed locally on the terminal equipment, for example, the acquired record is processed by a processor of the terminal equipment, and the delay time length is obtained according to the occurrence time sequence of the target audio signal in the record, so that the delay time length can also be obtained under the condition that the terminal equipment does not have remote communication capability.

It should be noted that, the delay adjustment method in the above embodiment may be applied to any stage when the user uses the terminal device, for example, before playing the audio and video by using the terminal device, or in the process of playing the audio and video by using the terminal device, and at this time, delay adjustment is performed by using the audio played by the terminal device as the target audio signal, so that dynamic detection and dynamic delay setting can be implemented, and multiple devices and multiple usage scenarios can be compatible, and the method is accurate and convenient.

Fig. 4 is a flow chart of another delay adjustment method, which may be used with a speech processing device, shown in at least one embodiment of the present disclosure, the method comprising:

In step 402, a recording containing a target audio signal played by a first audio output device and a second audio output device simultaneously is obtained, where the first audio output device is located in a terminal device, and the second audio output device is externally connected to the terminal device.

In this embodiment, the intelligent voice system is built in the voice processing device, and the position where the voice processing device is located is not limited in this embodiment, for example, the voice processing device may be located in the cloud, located at a mobile phone end of a user, or located in a terminal device itself. The intelligent voice system in the voice processing device has voice recognition capability, and the delay time between the target audio signals can be determined according to the record.

The step of receiving a sound recording sent by a terminal device, wherein the sound recording is obtained by recording the target audio signal simultaneously played by the first audio output device and the second audio output device through a first sound recording device of the terminal device; or receiving a recording sent by a second recording device outside the terminal equipment, wherein the recording is obtained by the second recording device recording the target audio signal by simultaneously playing the first audio output equipment and the second audio output equipment.

In step 404, a time delay is determined according to a time difference between the target audio signals respectively played by the first audio output device and the second audio output device included in the recording.

When the first audio output device and the second audio output device respectively play the target audio signals, the target audio signals played by the second audio output device are slower than the target audio signals played by the first audio output device, namely, a time difference exists between the first audio output device and the second audio output device, and the time difference is the time delay duration to be determined in the step. The delay time can be used for adjusting the played audio and video of the terminal equipment and the audio output equipment so as to synchronize the played audio and video.

And under the condition that the number of the second audio output devices externally connected with the terminal device is one, determining a delay time according to the time difference between the target audio signals respectively played by the first audio output device and the second audio output device.

And under the condition that the number of the second audio output devices externally connected with the terminal device is multiple, determining delay time lengths corresponding to the multiple second audio output devices respectively according to multiple time differences between the target audio signals respectively played by the first audio output device and the multiple second audio output devices.

In step 406, the delay time length is sent to the terminal device, so that the terminal device performs delay adjustment according to the delay time length.

And under the condition that the number of the second audio output devices externally connected with the terminal device is one, sending the delay time to the terminal device, so that the terminal device carries out delay adjustment on the terminal device according to the obtained delay time.

And under the condition that the number of the second audio output devices externally connected with the terminal device is multiple, sending the multiple delay time lengths to the terminal device, so that the terminal device can carry out delay adjustment on the terminal device and the multiple second audio devices according to the multiple delay time lengths.
