Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a flow chart illustrating a method of implementing voice broadcast correction according to an exemplary embodiment. As shown in fig. 1, the method for implementing the voice broadcast correction may include the following steps.
In step 110, ambient audio data of the environment in which the speech device is located is collected by a microphone.
The voice device is an intelligent device with a voice function and capable of voice broadcasting, such as a smart television and a smart sound box capable of voice broadcasting. The ambient audio data is the overall audio data of the environment in which the speech device is located, and includes audio data output by the speech device (e.g., device audio data) and noise other audio data of the environment in which the speech device is located (e.g., noise interference data).
The microphone is arranged for recording voice instructions for voice control of the voice device. And recording a voice instruction for carrying out voice control on the voice equipment through the microphone, so that the voice equipment broadcasts corresponding feedback sound according to the voice instruction of the user. Ambient audio data of an environment in which the speech device is located is collected by a microphone.
In a specific implementation of an exemplary embodiment, the voice device is a smart television for performing voice broadcast, the smart television is provided with a microphone, the microphone may be disposed on a voice remote controller of the smart television or on the smart television, a user performs voice control on the smart television through the microphone on the voice remote controller, the smart television is to perform broadcast of feedback sound according to the voice control of the user, and at this time, environmental audio data of an environment where the smart television is located is collected through the microphone, so as to obtain noise in the environment where the smart television is located.
In step 130, noise interference data is extracted from the ambient audio data.
The noise interference data is used to represent noise in the environment where the voice device is located, such as audio data formed by a user talking near the voice device.
In this embodiment, the environmental audio data includes device audio data and noise interference data output by the speech device.
Because the environment audio data collected by the microphone contains noise interference data and can also comprise voice audio data output by the voice equipment, the noise interference data can be extracted from the environment audio data, so that the interference of noise on feedback sound broadcasted by the voice equipment can be reduced according to the noise interference data subsequently.
In step 150, the volume of the feedback sound of the speech device is adjusted according to the noise interference data.
The feedback sound of the voice equipment is the voice broadcasted by the voice equipment according to the voice control of the user, and the feedback sound of the voice equipment can be used for prompting that the voice control performed by the user is successfully executed, can also be used for prompting that the voice control performed by the user is failed, and can also be used for prompting the user to perform the voice control again.
As described above, the noise interference data is used to represent noise in the environment in which the speech device is located, and therefore, the volume of the feedback sound of the speech device is adjusted in order to reduce interference of the noise with the feedback sound of the speech device.
For example, if the noise volume is too large, the feedback sound volume is increased, whereas if the noise volume is relatively small, the feedback sound volume may be kept unchanged.
Of course, in other embodiments, the volume of the feedback sound may be appropriately reduced when the noise volume is small, so as to avoid sound break during voice broadcasting.
In step 170, the feedback sound whose volume has been adjusted is broadcast.
For the user, the feedback sound volume of the feedback sound is adjusted according to the noise interference data, so that the feedback sound with sufficient clarity can be received.
This embodiment has realized adjusting the feedback sound volume of voice device, makes the user can obtain more clear feedback sound, has solved the voice broadcast unclear, and user experience is relatively poor problem.
FIG. 2 is a flow diagram of one embodiment of step 130 of the corresponding embodiment of FIG. 1. As shown in fig. 2, this step 130 may include the following steps.
In step 131, when the device audio data is output in the voice broadcast process, the device audio data is acquired.
The device audio data is audio data output by the voice device. In a specific implementation of an exemplary embodiment, the voice device is a smart television performing voice control, and the device audio data is audio data output when the smart television plays a television program. In the voice broadcasting process, when the voice equipment still outputs the audio data of the equipment, the voice equipment acquires the audio data of the equipment output by the voice equipment. In other exemplary embodiments, the voice device may also stop outputting the device voice data first, so that the user can hear the feedback sound broadcasted by the voice device without being affected by the device audio data, and at this time, the device audio data is not acquired.
In step 133, the device audio data is removed from the environmental audio data according to the correlation between the device audio data and the environmental audio data, resulting in noise interference data.
The environment audio data is the whole audio data of the environment where the voice equipment is located, so the environment audio data also comprises the equipment audio data output by the voice equipment, and the equipment audio data is eliminated from the environment audio data according to the correlation between the equipment audio data and the environment audio data, so that the noise interference data is obtained. In this embodiment, the device audio data is eliminated from the environment audio data through the strong correlation between the device audio data and the environment audio data, and in the implementation of other embodiments, the device audio data may also be eliminated from the environment audio data through the weak correlation between the device audio data and the environment audio data, which is not limited in this disclosure.
This embodiment enables the elimination of device audio data from the ambient audio data resulting in noise interference data.
Fig. 3 is a flowchart illustrating a method of implementing a voice announcement correction according to another exemplary embodiment. As shown in fig. 3, the method for implementing the voice broadcast correction may further include the following steps.
In step 210, the average magnitude of the device audio data is calculated.
When the voice device outputs different device audio data, the amplitude of the device audio data will be different due to the different audio sources of the different device audio data. In one specific implementation of the exemplary embodiment, the voice device is a smart television, and the amplitude of the output device audio data varies due to different television program sources played by the smart television. The accuracy of the voice broadcast correction is increased by calculating the average amplitude of the audio data of the device.
In step 230, the average amplitude of the device audio data is compared to a feedback tone amplitude reference value.
Wherein, feedback sound amplitude benchmark value is the standard value of the amplitude of the feedback sound that voice equipment reported, when not adjusting the feedback sound that voice equipment reported promptly, the amplitude of the feedback sound that voice equipment reported. The amplitude is represented on the speech device in the form of volume.
The average amplitude of the device audio data and the reference value of the feedback sound amplitude are judged by comparing the average amplitude of the device audio data with the reference value of the feedback sound amplitude, so that the device audio data are adjusted according to the judgment result, and the influence of the device audio data on the feedback sound broadcasted by the voice device is reduced.
In step 250, when the average amplitude of the device audio data is greater than the feedback tone amplitude reference value, a negative gain coefficient is set for the device audio data, and the device output volume indicated by the device audio data is reduced according to the negative gain coefficient.
When the average amplitude of the device audio data is greater than the reference value of the amplitude of the feedback sound, that is, the volume of the device audio output by the voice device is greater than the volume of the feedback sound, a negative gain coefficient for reducing the output volume of the device is set for the device audio data, and the output volume of the device indicated by the device audio data is reduced according to the set negative gain coefficient, so that the output volume of the device when the device audio data is output by the voice device is reduced.
In a specific implementation of an exemplary embodiment, the average amplitude of the device audio data is M1, the feedback tone amplitude reference value is M, and when M1 is greater than M, the negative gain coefficient S-is set to S-k-x (M/M1), where k-may be set to 1,1/2,1/3, etc., by which the negative gain coefficient S is set to M-The device output volume indicated by the device audio data is reduced.
This embodiment realizes that the negative gain coefficient is set for the device audio data when the average amplitude of the device audio data is larger than the reference value of the amplitude of the feedback tone
FIG. 4 is a flow diagram of one embodiment of step 150 of the corresponding embodiment of FIG. 1. As shown in fig. 4, this step 150 may include the following steps.
In step 151, the average magnitude of the noise interference data is calculated.
Because the environment of the voice device is different, the environmental audio data can change according to the different environment of the voice device, that is, the noise interference data obtained according to the environmental audio data can change according to the different environment of the voice device. The effect of the amplitude variation of the noise disturbance data is reduced by calculating the average amplitude of the noise disturbance data.
In step 153, the average magnitude of the noise interference data is compared to a noise interference data magnitude reference value.
The reference value of the amplitude of the noise interference data is a threshold value at which the output noise interference data does not affect the feedback voice broadcast by the voice equipment. When the average amplitude of the noise interference data is larger than the reference value of the amplitude of the noise interference data, the output noise interference data influences the feedback sound of broadcasting.
Whether the noise interference data affect the reported feedback sound is judged by comparing the average amplitude of the noise interference data with the amplitude reference value of the noise interference data, so that the volume of the feedback sound is adjusted according to the judgment result, and the influence of the noise interference data on the reported feedback sound of the voice equipment is reduced.
In step 155, when the average amplitude of the noise interference data is greater than the noise interference data amplitude reference value, a positive gain coefficient is set for the feedback tone, and the volume of the feedback tone is increased according to the positive gain coefficient.
When the average amplitude of the noise interference data is larger than the reference value of the amplitude of the noise interference data, the noise of the environment where the voice equipment is located is influenced by the broadcast feedback sound, a positive gain coefficient used for enhancing the volume of the feedback sound is set for the feedback sound at the moment, the volume of the feedback sound is increased according to the positive gain coefficient, and therefore the influence of the noise of the environment where the voice equipment is located on the broadcast feedback sound is reduced.
In one exemplary embodiment, the average amplitude of the noise interference data is N1, the noise interference data amplitude reference value is N, and when N1 is greater than N, the positive gain factor S is obtained+Is set as S+＝k+×(N1/N)，k+Can be set to 1,2,3, etc., by a positive gain factor S+The volume of the feedback sound is increased.
This embodiment enables increasing the volume of the feedback tone according to the positive gain factor.
Fig. 5 is a flowchart illustrating a method of implementing a voice broadcast correction according to another exemplary embodiment. The method for realizing voice broadcast correction can also comprise the following steps.
In step 310, the volume at which the voice device outputs device audio data is obtained.
In step 330, a noise interference data amplitude corresponding to the volume is obtained according to the correspondence between the volume and the noise interference data amplitude, and the noise interference data amplitude is used as a noise interference data amplitude reference value.
The method comprises the steps of obtaining the volume when audio data of voice equipment is output, obtaining a linear or curve relation between the volume and a noise interference data amplitude value through experimental results of a large number of experiments, namely, each volume of the voice equipment has a corresponding noise interference data amplitude value, obtaining the corresponding noise interference data amplitude value according to the volume when the audio data of the voice equipment is output, and taking the noise interference data amplitude value as a noise interference data amplitude value reference value.
According to the embodiment, the noise interference data amplitude corresponding to the volume is obtained, and the noise interference data amplitude is used as the noise interference data amplitude reference value.
In an exemplary embodiment, the method for implementing voice broadcast correction may further include the following steps.
And restoring the equipment parameters of the voice equipment.
The device parameters comprise device output volume and feedback sound volume which are respectively adjusted according to a negative gain coefficient and a positive gain coefficient. By restoring the equipment parameters of the voice equipment, the voice equipment is restored to the state of not adjusting the output volume of the equipment and the volume of the feedback sound, and the influence on the user experience of the voice equipment is avoided.
The embodiment realizes the equipment parameter restoration of the voice equipment, and avoids influencing the user experience of the voice equipment.
