For example, the audio control system comprises the control device 101 and the audio output device 102 and 104 shown in fig. 1, the control device 101 sends information to one or more of the audio output device 102 and 104 to control one or more of the audio output device 102 and 104 to output audio.
As an example, one part of the audio control system is disposed in the cloud, and the other part is disposed in the user environment, for example, the control device 101 is disposed in the cloud, and the audio output devices 102 and 104 are disposed in various rooms of the user's house; as a further example, the audio control system is arranged entirely in the user's environment, e.g. both the control means 101 and the audio output means 102 and 104 are arranged in the user's house. Optionally, the control device (e.g. 101) provided by the embodiment of the present disclosure is integrated with the audio output device (e.g. 102-104) provided by the embodiment of the present disclosure, for example, for the audio control system formed by the control device 101 and the audio output device 102-104 shown in fig. 1, the control device 101 may be integrated on one of the audio output devices 102-104, for example, on the audio output device 102.
The method for controlling the output audio provided by the embodiment of the disclosure can be executed by the aforementioned control device, and the method for outputting the audio provided by the embodiment of the disclosure can be executed by the aforementioned audio output device. The control device and/or the audio output device may be implemented as software, as hardware, or as a combination of software and hardware, for example, the control device includes a computer device, so that the method for controlling the output audio provided by the embodiment is executed by the computer device, for example, the audio output device includes a computer device, so that the method for outputting the audio provided by the embodiment is executed by the computer device. As understood by those skilled in the art, a computer device may have various forms including, for example, a server or an intelligent terminal. As an example of one specific form of the audio output device, the control audio output device includes a smart speaker; as an example of a specific form of the control device, the control device comprises a smart speaker (e.g., the control device is integrated in the smart speaker).
Fig. 2 is a flowchart illustrating interaction between a control device and an audio output device according to an embodiment of the disclosure, for example, the control device (101) interacts with one or more of the M audio output devices (102 and 104). According to the interaction process of fig. 2, the control device provided by the embodiment of the present disclosure implements the method for controlling the output audio provided by the embodiment of the present disclosure, and the audio output device provided by the embodiment of the present disclosure implements the method for outputting the audio provided by the embodiment of the present disclosure.
As shown in fig. 2, the interaction process between the control device and the audio output device provided by the embodiment of the disclosure includes the following steps:
step S201, obtaining distance indication information (the M audio output devices);
in step S201, as described above, the user may arrange M audio output devices, where M is an integer greater than 1, and then in step S201, the M audio output devices respectively acquire M pieces of distance indication information. Optionally, the distance indication information is used to indicate a distance value.
In an alternative embodiment, step S201: acquiring distance indication information, comprising: and acquiring a voice receiving signal, and taking the voice receiving signal as the distance indication information. For example, for a voice source signal sent by a user (i.e. the voice of the user), if the M audio output devices all detect the voice source signal, M voice receiving signals are obtained respectively, and the M voice receiving signals correspond to the same voice source signal. In implementation, for example, M audio output devices respectively acquire M voice receiving signals corresponding to the voice of the user through respective input devices such as microphones in response to detecting the voice of the user, and the M voice receiving signals may be analog signals and stored in a file. In this alternative embodiment, the M audio output devices may respond to only the preset voice source signal, such as the voice source signal corresponding to the wakeup word of the smart speaker, or the voice source signal corresponding to the specific instruction, and obtain the voice receiving signal corresponding to the preset voice source signal, but not respond to the non-preset voice source signal. Since the M audio output devices are arranged at different positions, and the distances from the user or the source audio signal are often different, which causes differences in the M received voice signals received by the M audio output devices, the distance values between (the placement positions of) the M audio output devices and (the generated positions of) the source audio signal can be indicated by the M received voice signals, and thus the M received voice signals can be used as the distance indication information indicating the distance values. As understood by those skilled in the art, the above distance value may also be considered as an (approximate) distance value between the audio output device and the user, which will not be described in detail later. How to indicate the distance value of the audio output device from the source audio signal by the speech reception signal will be described in the following embodiments.
It should be noted that, because there are various situations in the user environment, the quality (e.g., sound size) of the voice of the user is different, and there may be a situation that the voice of the user is not detected in the multiple audio output devices arranged by the user, for example, the user arranges M + N audio output devices, where N is a positive integer, but only M audio output devices detect the voice of the user, in this case, the audio output device that does not detect the voice of the user will not acquire the voice receiving signal, and for the following embodiments, there may be a situation that the distance indication information and/or the voice input signal (wireless signal) are not acquired in the above M + N audio output devices, and there may be N audio output devices that do not acquire the distance indication information and/or the voice input signal (wireless signal), and details thereof will not be described later.
In another alternative embodiment, step S201: acquiring distance indication information, comprising: and acquiring a voice receiving signal, and determining the distance indication information according to the voice receiving signal. For how the M audio output devices obtain their respective voice receiving signals, reference may be made to the foregoing embodiments, which are not described herein again. After the M audio output devices respectively acquire the voice receiving signals, the distance indicating information is determined according to the respective acquired voice receiving signals. For example, one of the M audio output devices determines its corresponding distance indication information according to the obtained speech receiving signal, and the other of the M audio output devices may refer to the same or corresponding descriptions. The one audio output apparatus determines the power of the received voice signal after acquiring the received voice signal, compares the power of the received voice signal with a preset power, estimates a distance value by a difference or a ratio of the power of the received voice signal and the preset power, and indicates the distance value by the distance indication information, wherein the estimated distance value may be considered as a distance value between (a placement position of) the one audio output apparatus and (a generation position of) the source voice signal. As will be appreciated by those skilled in the art, the distance indicating information may be determined from the received voice signal in other ways besides the above implementation, and any existing or future techniques for determining the distance to a sound source based on the received voice signal may be applied to the embodiments of the present disclosure.
Step S202, transmitting the distance indication information to the control device (the M audio output devices);
in step S202, the M audio output devices respectively send the distance indication information obtained in step S201 to the control device, for example, send the distance indication information to the control device through wifi, bluetooth, or wired broadband. For embodiments in which the control device is integrated on one of the M audio output devices, the audio output device integrated with the control device may send the distance indication information to the control device via an internal communication line, such as a bus or a circuit connection.
Step S203, (the control device) receives M pieces of distance indication information from the M audio output devices, which correspond to the M pieces of distance indication information one to one;
since the M audio output devices respectively transmit the respective acquired distance indication information to the control device in step S202, the control device accordingly receives the distance indication information from the M audio output devices respectively in step S203.
Step S204, (the control device) determines a minimum distance value from M distance values respectively indicated by the M distance indication information;
in step S204, the control device determines a minimum distance value among M distance values respectively indicated by the M distance indication information according to the M distance indication information. For the embodiment that the distance indication information includes the voice receiving signal, in step S204, the control device respectively receives M voice receiving signals from the M audio output devices, so that the control device may determine M distance values respectively indicated by the M voice receiving signals according to the M voice receiving signals, and further determine the minimum distance value therefrom, and as to how to determine the distance value according to the voice receiving signals, reference may be made to the foregoing embodiment, for example, the distance value may be estimated according to a difference or a ratio between power of the voice receiving signals and preset power, which is not described herein again; for the aforementioned embodiment in which the audio output devices determine the distance indicating information according to the voice received signal, since each audio output device has already determined the distance indicating information and the distance indicating information indicates a distance value, in step S204, the control device will determine a minimum distance value from the M distance values indicated by the M distance indicating information.
Step S205, sending (the control device) audio output indication information to a first audio output device of the M audio output devices, wherein the distance indication information corresponding to the first audio output device indicates the minimum distance value, and the audio output indication information is used for indicating the first audio output device to output audio;
since the control device determines the distance indicating information indicating the minimum distance value among the M pieces of distance indicating information, it is possible to determine the first audio output device corresponding thereto from the distance indicating information indicating the minimum distance value, that is, the first audio output device among the M pieces of audio output devices transmits the distance indicating information indicating the minimum distance value to the control device. Since the M distance indication information respectively indicate the distance values between the M audio output devices and the voice source signal and the first audio output device corresponds to the minimum distance value, the distance between the first audio device and the voice source signal is considered to be the closest, and therefore, in step S205, the control device sends audio output indication information to the first audio output device, indicating that the first audio output device of the M audio output devices provides a service for the user. Alternatively, the control device may send stop output instruction information to the other audio output devices of the M audio output devices except the first audio output device, where the stop output instruction information is used to instruct the other audio output devices to stop outputting audio, that is, the control device may control the other audio output devices not to respond to the voice source signal by sending stop output instruction information to the other audio output devices of the M audio output devices except the first audio output device.
Step S206, (the first audio output means) outputs a preset audio in response to receiving the audio output instruction information from the control means.
In step S206, the first audio output device receives the audio output instruction information from the control device, and outputs a preset audio based on the audio output instruction information in order to provide a service to the user. The playing of the preset audio is regarded as a response to a voice source signal of the user, for example, the voice source signal includes a wake-up signal for waking up the smart sound box, and then the preset audio includes a response to the wake-up signal of the user; for another example, if the voice source signal includes an instruction instructing the smart speaker to play the preset audio, the first audio output device will play the preset audio in response to the instruction. Optionally, the other audio output devices except the first audio output device among the M audio output devices do not receive the audio output indication information within a first preset time period after the distance indication information is respectively sent, and stop outputting any audio, that is, the control device controls the other audio output devices not to respond to the voice source signal by not sending stop output indication information to the other audio output devices except the first audio output device among the M audio output devices.
Through the above steps S201 to S206, the M audio output devices can send the M distance indication information obtained by each of the M audio output devices to the control device, the control device determines a minimum distance value from the M distance values indicated by the M distance indication information, and sends the audio output indication information to the first audio output device corresponding to the minimum distance value, and the first audio output device outputs the preset audio according to the audio output indication information, so that the control device coordinates the M audio output devices to output the audio, thereby improving the interaction efficiency.
With the development of positioning technology, in addition to a manner of determining a distance value from a received voice reception signal corresponding to a voice source signal, a relative position to a signal source may be determined from various signal sources.
In an optional embodiment provided by the present disclosure, the step S201: acquiring distance indication information, comprising: receiving a wireless reception signal from a wireless device; and taking the wireless receiving signal as the distance indication information. In this alternative embodiment, the wireless reception signal includes a wireless reception signal received by the audio output device for a wireless source signal emitted by a user's smart device (including but not limited to various forms of smart terminals, such as smart watches, smart phones, etc.). Optionally, the wireless receiving signal includes a bluetooth receiving signal, and correspondingly, the wireless source signal includes a bluetooth source signal; or, the wireless receiving signal comprises an infrared receiving signal, and correspondingly, the wireless source signal comprises an infrared source signal; or, the wireless receiving signal comprises an ultra-wideband (UWB) receiving signal, and correspondingly, the wireless source signal comprises an ultra-wideband source signal; or, the wireless receiving signal comprises a wifi receiving signal, and correspondingly, the wireless source signal comprises a wifi source signal.
Taking the wireless receiving signals include bluetooth receiving signals, and the wireless source signals include bluetooth source signals, for example, for bluetooth source signals sent by an intelligent device used by a user, in step S201, if all the M audio output devices detect the bluetooth source signals, M bluetooth receiving signals are received, respectively, and the M bluetooth receiving signals correspond to the same bluetooth source signal. In an implementation, for example, M audio output devices, in response to detecting a bluetooth source signal broadcasted by the smart device of the user, will respectively generate M data packets and/or data files corresponding to the bluetooth source signal through respective bluetooth modules and the like, that is, store the bluetooth reception signal through the data packets and/or data files. It should be noted that, due to various situations in the user environment, the signal strength of the smart device of the user is different, and there may be a situation where the bluetooth source signal of the smart device of the user is not detected or received in the plurality of audio output apparatuses arranged by the user, for example, the user arranges M + N audio output apparatuses, where N is a positive integer, but only M audio output apparatuses detect the bluetooth source signal of the smart device of the user, in which case, the audio output apparatus that does not detect the bluetooth signal of the smart device of the user will not acquire the bluetooth received signal.
Similarly, the smart device used by the user may further send an infrared source signal, for example, the infrared source signal carries an IR identifier, and the M audio output devices respectively generate M infrared receiving signals corresponding to the infrared source signal through respective infrared modules and the like in response to detecting the infrared source signal; the intelligent device used by the user can also emit an ultra-wideband source signal (an ultra-narrow pulse of nanosecond or below), the M audio output devices respond to the detection of the ultra-wideband source signal, and respectively generate M data packets and/or data files corresponding to the ultra-wideband source signal through respective ultra-wideband modules and the like, that is, the ultra-wideband receiving signal is stored through the data packets and/or data files, and the data packets and/or data files record the time when the intelligent device used by the user emits the ultra-wideband source signal and the time when each audio output device detects the ultra-wideband source signal (and also record the time when the data packets and/or data files corresponding to the ultra-wideband source signal are generated); the intelligent device used by the user can also send out wifi source signals, and the M audio output devices respond to the detected wifi source signals and respectively generate M wifi receiving signals corresponding to the wifi source signals through respective wifi modules and the like.

Wherein the M pieces of distance indication information respectively determined by the M pieces of audio output devices indicate distance values of the respective audio output devices from the wireless source signal.
For the above alternative embodiment, the M audio output devices send M pieces of distance indication information respectively determined to the control device in step S202, the M pieces of distance indication information respectively indicate distance values, accordingly, the control device receives the M pieces of distance indication information in step S203, and the control device determines the minimum distance value from the M pieces of distance values respectively indicated by the M pieces of distance indication information in step S204.
