The method for playing audio provided by the embodiment of the present application is generally executed by the terminal device 101, and accordingly, the apparatus for playing audio is generally disposed in the terminal device 101. Alternatively,
it should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for playing audio in accordance with the present application is shown. The method for playing audio includes the steps of:
In this embodiment, the execution main body of the method for playing audio (such as the terminal 101 shown in fig. 1) may acquire the audio to be played through a wired connection manner or a wireless connection manner. As an example, the execution subject may locally acquire pre-stored audio to be played. As yet another example, the execution body may acquire audio to be played from a communicatively connected electronic device. The audio to be played may include various audio that can be played. The audio to be played may include an audio file, such as song audio, by way of example. As yet another example, the audio to be played may include audio generated by a speech synthesis technique, such as a "i'm listening" speech file.
In this embodiment, the execution main body may acquire the voice input instruction information of the target device by a wired connection manner or a wireless connection manner. The voice input indication information may be used to indicate whether the target device is allowed to receive voice input in a preset time period. The voice input may generally refer to that the execution body receives a voice of a user for voice interaction. In practice, whether to allow receiving the voice input may be embodied as whether a microphone is turned on or not, or whether to transmit the collected voice to a processor in the execution main body, which is not limited herein. The preset time period is generally a time period counted from the present or later (e.g., after 1 minute). Optionally, the preset time period may also be related to the time when the audio is played. For example, assuming that the audio is played after 2s, the preset time period may be a time period from 2s to 1 min. The target device may be any device that is specified in advance according to actual application requirements. The target device may also be a device that is determined according to rules, for example, a device that plays audio in a manner controlled by the target device. When the execution agent is a terminal, the target device may be the execution agent itself.
As an example, in response to receiving an instruction characterizing switching to a voice interaction mode, the execution body may generate voice input indication information indicating that the target device is allowed to receive voice input for a preset time period. The instruction for switching the representation to the voice interaction mode may include a preset wake-up word.
In this embodiment, the execution main body may acquire the voice input instruction information from the target apparatus. As an example, the voice input indication information may be preset, for example, voice input indication information that indicates that the target device is not allowed to receive voice input for a preset time period by default. As still another example, the voice input indication information indicating whether the target device allows receiving the voice input for a preset time period may be switched according to a preset time.
In this embodiment, the execution subject may determine the frequency band matching the voice input indication information acquired in step 202 in various ways. As an example, in response to determining that the acquired voice input indication information indicates that the target device is not allowed to receive voice input for a preset time period, the execution main body may determine a frequency band corresponding to the audio to be played as a frequency band matching the voice input indication information.
As still another example, in response to determining that the acquired voice input indication information indicates that the target device is allowed to receive voice input for a preset time period, the execution main body may determine a frequency band matching the voice input indication information according to the following steps: first, the frequency band of the audio to be played is determined. And then, determining the intersection between the frequency band of the audio to be played and the preset frequency band. The preset frequency band can be a voice frequency band for a person to speak under the voice recognition scene. Then, in response to determining that the intersection meets a preset playing condition, the execution main body may determine a frequency band corresponding to the audio to be played as a frequency band matched with the voice input indication information. In response to determining that the intersection does not satisfy the preset playing condition, the execution main body may determine a frequency band matched with the voice input indication information as a frequency band higher than a frequency band corresponding to the audio to be played. The preset playing condition may include, but is not limited to, at least one of the following: the audio time corresponding to the intersection between the frequency bands is smaller than a preset time threshold, and the minimum frequency corresponding to the intersection between the frequency bands is larger than a preset frequency threshold.
In some optional implementation manners of this embodiment, in response to determining that the voice input indication information is used to indicate that the target device is not allowed to receive the voice input in the preset time period, the execution main body may further select, from the second preset correspondence table, a frequency band that is consistent with a frequency band corresponding to the audio to be played. The second preset correspondence table may be configured to represent a correspondence between a frequency band and voice input indication information. For example, the voice input indication information for indicating that the target device is not allowed to receive the voice input in the preset time period corresponds to a first frequency band, and the voice input indication information for indicating that the target device is allowed to receive the voice input in the preset time period corresponds to a second frequency band, where the second frequency band may be a subset of the first frequency band.
And step 204, playing the audio to be played according to the determined frequency band.
In this embodiment, the execution main body may play the audio to be played in various ways according to the determined frequency band. As an example, in response to determining that the determined frequency band is consistent with the frequency band with the playing audio, the execution main body may directly play the audio to be played. As another example, the execution main body may further transform the audio to be played to the determined frequency band and then play the audio.
In some optional implementation manners of this embodiment, based on the above optional implementation manners, the execution main body may further play the audio to be played through the following steps:
firstly, sound wave transformation is carried out on audio to be played to generate target audio.
In these implementations, the execution main body may perform sound wave transformation on the audio to be played in various ways to generate the target audio. The frequency bands of the target audio are usually a subset of the determined frequency bands. The sound wave transformation can be used for mapping the frequency band of the audio to be played to the determined frequency band range. The manner of sound wave transformation may include amplification operations for each frame frequency in the audio, which may include, but is not limited to, at least one of: multiplied by a preset value greater than 1, plus a preset value greater than 0, etc.
And secondly, playing the target audio.
In these implementations, the execution subject may play the target audio generated in the first step.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of a method for playing audio according to an embodiment of the present application. In the application scenario of fig. 3, the user 301 says the wake-up word "small a" 303 to the terminal device 302. The terminal device 302 locally obtains the audio to be played "please talk …, i.e. listen" 304 in response to the wake-up word 303. The terminal device 302 acquires voice input indication information 305 indicating that the terminal device is allowed to receive voice input for a preset time period according to the received wake-up word 303. Then, the terminal device 302 may determine that the frequency band matching the voice input indication information 305 is a frequency band 306 with a higher frequency than the audio 304 to be played. Finally, the terminal device 302 may play the audio "please talk …, i am listening" 307 in the determined higher frequency band 306.
At present, in one of the prior arts, a filter circuit is usually built in an intelligent device to filter out noise similar to a human voice frequency band, which results in an increase in hardware manufacturing and maintenance costs. The method provided by the embodiment of the application determines the frequency band for playing the audio according to the voice input indication information, so that the audio output frequency band is improved under the situation that human-computer interaction is needed, and the influence on human voice is reduced. Moreover, the audio is played in a normal mode under the situation that human-computer interaction is not needed, and the auditory experience of a user is guaranteed to be influenced as little as possible.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for playing audio is shown. The process 400 of the method for playing audio includes the following steps:
In some optional implementations of this embodiment, in response to receiving an instruction to characterize playing audio, an execution subject of the method for playing audio (e.g., the terminal device 101 shown in fig. 1) may generate voice input indication information indicating that the target device is not allowed to receive voice input for a preset time period. The instruction for playing the audio may be, for example, "play a song" or "play a piece of funny video" received in the voice interaction process.
It should be noted that, since most video files will have corresponding audio integrated therein, the instruction for playing audio may also include an instruction for playing video files with audio.
And step 403, in response to determining that the voice input indication information is used for indicating that the target device is allowed to receive voice input in a preset time period, selecting a target number of frequency bands from the first preset corresponding relation table according to the sequence of the frequency bands from high to low.
In this embodiment, in response to determining that the voice input indication information indicates that the target device is allowed to receive the voice input in the preset time period, the execution main body may select the target number of frequency bands from the first preset correspondence table in order of frequency bands from top to bottom. The first preset correspondence table may be configured to represent a correspondence between a frequency band and voice input indication information. The first preset mapping table may be the same as or different from the second preset mapping table, and is not limited herein. As an example, the frequency range of sound that can be heard by the human ear is 20Hz to 20 kHz. The first preset correspondence table may divide the frequency range into a preset number of frequency bands. Alternatively, in order to enrich the frequency range of the played audio, there may be an intersection between the above frequency bands. The target number may be any value (e.g., 2 or 3) specified in advance, or may be a value determined according to the actual application requirement (e.g., 50% of the preset number).
In step 404, a frequency band matching the voice input indication information is determined from the target number of frequency bands.
In this embodiment, the executing entity may determine a frequency band matching the voice input indication information from the target number of frequency bands selected in step 403 by various methods. As an example, the execution main body may randomly select a frequency band from the target number of frequency bands as a frequency band matched with the voice input indication information. As yet another example, the execution body may first determine a statistical value of a frequency band of the audio to be played. Wherein, the frequency band statistic may include, but is not limited to, at least one of the following: maximum, minimum, mean, variance, median. Then, the execution main body may select a frequency band having a statistical value closest to the statistical value of the frequency band of the audio to be played from the target number of frequency bands as a frequency band matched with the voice input indication information.
In some optional implementation manners of this embodiment, in response to determining that the voice input indication information is used to indicate that the target device is not allowed to receive the voice input in the preset time period, the execution main body may further select, from the second preset correspondence table, a frequency band that is consistent with a frequency band corresponding to the audio to be played as the frequency band that is matched with the voice input indication information. The second preset correspondence table may be configured to represent a correspondence between a frequency band and voice input indication information. The above consistency may refer to the same, or may refer to that the ratio of the frequency bands in the overlapping portion exceeds a preset threshold, which is not limited herein.
And 405, playing the audio to be played according to the determined frequency band.
As can be seen from fig. 4, the flow 400 of the method for playing audio in the present embodiment refines the step of determining the frequency band matching the voice input indication information. Therefore, the scheme described in the embodiment can set a proper output frequency band under the situation that human-computer interaction is needed, so that the interference on human voice input can be reduced, and the uncomfortable influence of the rising of the audio frequency on the auditory experience of a user is reduced as much as possible.
With further reference to fig. 5, as an implementation of the methods shown in the above-mentioned figures, the present application provides an embodiment of an apparatus for playing audio, which corresponds to the embodiment of the method shown in fig. 2, and which is particularly applicable to various electronic devices.

The determining module may be configured to determine a frequency band matching the voice input indication information from the target number of frequency bands.
In some optional implementations of this embodiment, the determining unit 503 may be further configured to be a selecting module, configured to select, in response to determining that the voice input indication information is used to indicate that the target device is allowed to receive voice input in a preset time period, a target number of frequency bands from the first preset correspondence table in an order from high to low; and the determining module is configured to determine a frequency band matched with the voice input indication information from the target number of frequency bands.
In some optional implementations of the present embodiment, the second obtaining unit 502 may be further configured to: in response to receiving an instruction characterizing playing of audio, generating voice input indication information for indicating that the target device is not allowed to receive voice input for a preset time period.

Wherein the frequency bands of the target audio may be a subset of the determined frequency bands. The playing module may be configured to play the target audio.
The apparatus provided in the foregoing embodiment of the present application first obtains the audio to be played through the first obtaining unit 501. Then, the second acquisition unit 502 acquires the voice input instruction information of the target apparatus. Wherein the voice input indication information is used for indicating whether the target device is allowed to receive the voice input in a preset time period. After that, the determination unit 503 determines a frequency band matching the voice input instruction information. The playing unit 504 plays the audio to be played according to the determined frequency band. Therefore, the audio output frequency band is improved under the situation that human-computer interaction is needed, and the influence on human voice is reduced. Moreover, the audio is played in a normal mode under the situation that human-computer interaction is not needed, and the auditory experience of a user is guaranteed to be influenced as little as possible.
