Step 103: and determining the volume of the output audio according to the signal-to-noise ratio.
Step 104: and outputting response audio aiming at the voice command according to the volume.
The execution subject of the embodiment may be an intelligent device such as an intelligent sound box, which can play audio and execute voice commands. When receiving a voice command input by a user, the intelligent device acquires the sound of the current surrounding environment, and further determines the signal-to-noise ratio of the environment sound. Whether the surrounding environment is a noisy environment or a quiet environment can be known from the signal-to-noise ratio. The volume of the output audio is determined according to the situation of the surrounding environment, and the response audio with the corresponding volume is output according to the volume. The response audio with the volume is more suitable for the current surrounding environment, so that the user has better listening effect. For example, the signal-to-noise ratio is high and the surrounding environment is quiet, and a lower volume of response audio may be output. And vice versa.
The response audio in this embodiment may be response voice to the voice command, or music played after the voice command is executed.
Optionally, the method further comprises at least one of: step a1 and step a 2.

Or, according to the signal-to-noise ratio and the distance of the sound source, the volume of the output audio is determined together. Or, the volume of the output audio is determined according to the signal-to-noise ratio, the sound intensity of the voice command and the sound source distance. The volume determined in this way is more suitable for the current environment of the user and more suitable for the requirements of the user. That is, the volume determined in this manner is more accurate.
In this embodiment, the correspondence between the volume and the multiple combination conditions configured with the signal-to-noise ratio, the sound intensity of the voice command, and the sound source distance is preset, and the corresponding volume can be determined according to the correspondence.

And then carrying out weighted summation on the signal-to-noise ratio, the sound intensity and the distance so as to determine the corresponding volume. And presetting the corresponding relation between the summation result and the volume. For example, the summation result may be divided into a plurality of ranges, each range corresponding to a volume value. A plurality of sound factors can be effectively combined together in a weighted summation mode to jointly determine a proper volume.

Each weight is updated through the volume reached after the adjustment command is executed, so that the volume which meets the requirements of the user better can be determined when the summation is calculated according to the weights next time.

Step C2: and determining the volume of the output audio according to the signal-to-noise ratio and the audio type.
In this embodiment, when a voice command is executed, the response audio may be determined, and further, the audio type may be determined. The audio type may be speech, music (including music styles such as rock, light music, etc.), story-like audio books, etc. By combining the audio type and the signal-to-noise ratio, a more appropriate volume can be determined, so that the user has better listening effect.
In this embodiment, the audio type may be combined with the sound intensity and the sound source distance of the voice command to determine the corresponding volume.
And the weights of the signal-to-noise ratio, the sound intensity and the distance corresponding to each audio type can be configured. When the weight is updated, the weight corresponding to the audio type of the currently played response audio may be updated.
