The audio playing level is a level representing the volume of the audio output, and the audio playing level can also represent the proportional relation between the expected audio playing volume and the noise volume in the current playing environment. For example, the audio playback level may be a level that characterizes the signal-to-noise ratio, or a level that characterizes the volume of the output audio. Under the playing environment with the same noise, the set audio playing levels are different, and the volume of the output audio is also different. Generally, the audio playing volume is in inverse proportion to the signal-to-noise ratio, that is, the larger the audio playing volume is, the smaller the signal-to-noise ratio should be set correspondingly. For example, the audio playing level may be characterized by a high level, a medium level, a low level, or the like, or may be characterized by A, B, C, or may be characterized by 1, 2, 3, or the like, that is, the level representing manner of the audio playing level is not limited, the number of level divisions of the audio playing level is also not limited, and the audio playing level may be adaptively adjusted according to the service requirement.

Specifically, the terminal equipment receives the audio playing level selected by the user through the input device. Illustratively, the user may select a desired audio playing level through a display interface of the terminal device, through a touch screen on the display interface, or through mouse click, keyboard click, or the like. The audio playing grade can also be adjusted and selected by rotating the knob device to different gears through the knob device arranged on the terminal equipment. And different audio playing levels can be triggered and selected in a mode of pressing different keys through keys arranged on the terminal equipment.

In this embodiment, the terminal device may control the audio collection device to collect the ambient noise data from the current playing environment within a certain time period before the playing start time point of the audio to be played. For example, it may be 30 seconds, 10 seconds, or a smaller period of time, such as 100 milliseconds, etc. By collecting the ambient noise data before the audio is played, an appropriate playing volume can be determined before the audio to be played is played, so that the audio can be played quickly and accurately according to the determined playing volume when the playing start time point is reached.

The level identifies the relation between the volume of the played audio and the ratio of the real-time noise, and under the same noise scene, the set playing levels are different, and the volume of the played and output audio is also different.
Step 2: and capturing real-time noise. Recording noise (including office scenes, square scenes with large pedestrian volume, scene noise in a driving car of an automobile, rainy day scenes, scene noise such as bird-language cicada water flow and the like or extremely quiet night scenes) in a period of time (30 seconds, 10 seconds or smaller time intervals such as 100ms and the like, or a period of time with random indefinite duration) before playing the current audio in real time, recording the noise in a certain period of time, and transmitting the recorded noise audio clip (environmental noise data) to a playing audio system for noise analysis at intervals. Or the captured noise audio fragments can be recorded and uploaded in real time for analysis.
And 3, step 3: and calculating audio volume. According to the noise audio clip captured before or the noise collected in real time, the noise in the current environment is analyzed and calculated, and then according to the value of the playing audio level set currently, the volume of the currently optimal playing audio is calculated, wherein A = N x Z (namely N = A/Z). For the collected noise audio, the energy value of the audio to be played can be calculated according to the energy value of the noise and the set audio playing level, so that the proper audio energy value can be determined.
And 4, step 4: and setting and playing the volume of the audio. According to the result value of the volume calculation, the size of the output value of the audio output by the audio playing system is set, or according to the calculated target volume value, the audio energy of the audio to be played is amplified and reduced, or the amplitude of the audio is amplified and reduced, so that the audio playing system can play the audio with the proper volume which is matched with the noise volume in the current playing environment.
The application example can dynamically adjust the volume of the played audio according to the noise in the current playing environment and the set audio playing grade, can output the audio with proper volume in real time under the unstable noise condition, reduces the probability of non-response or false response events of the voice interaction system under the influence of noise change, and improves the authenticity and reliability of the automatic test result of the voice interaction system.
