specific embodiment

In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are some, but not all, embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other if there is no conflict.

The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

FIG. 1 is a flowchart of a method for adjusting volume based on voice control provided by an embodiment of the present application. As shown in Figure 1, the method includes:

Step S11, receiving voice input, where the voice input includes an instruction to adjust the volume;

For example, the voice input is first received, and then the host software is used to complete the recording processing, semantic analysis and understanding, and the final understanding result is transmitted to the host through a data protocol, and the host completes the volume adjustment action. Since the received voice input is dictated by the user, the voice input may be varied. Here, the embodiment of the present application extracts fixed information from the voice input dictated by the user, so as to identify the needs of the user. The voice input may include instructions for adjusting the volume, such as "volume up", "volume down", "volume up", "volume down", etc., which express the user's willingness to adjust the volume.

Step S12, detecting the volume range in which the volume is located;

For example, the volume range in which the current volume is located can be detected, and the subsequent volume adjustment methods are different in different volume ranges.

Step S13, determining the adjustment scheme of the voice input according to whether the voice input also includes a modifier corresponding to the instruction for adjusting the volume;

For example, the voice input may also include modifiers corresponding to the instruction to adjust the volume, for example, modifiers corresponding to the instruction to increase the volume: "inaudible", "inaudible", etc. indicate that the user is dissatisfied with the current volume or urgently needs the volume Adjusted voice. Whether or not to include this modifier results in a different regulation scheme.

Step S14, according to the instruction for adjusting the volume and the volume range in which the volume is located, and based on the determined adjustment scheme of the voice input, the volume is controlled to be adjusted.

For example, the host will control the increase or decrease of the volume through a digital signal processor (DSP), and finally play the sound through the speaker, and the user can feel the change of the volume. The determined adjustment scheme of the voice input, the instruction for adjusting the volume, and the volume range in which the volume is located will all affect the way of adjusting the volume. For the convenience of explanation, first analyze the determined voice input adjustment scheme and the command to adjust the volume, which can be divided into the following four situations:

First, the instruction to adjust the volume is an instruction to reduce the volume, and the determined adjustment scheme of the voice input is an adjustment scheme that does not include a modifier corresponding to the instruction to adjust the volume;

Second, the instruction to adjust the volume is an instruction to reduce the volume, and the determined adjustment scheme of the voice input is an adjustment scheme that includes a modifier corresponding to the instruction to adjust the volume;

Third, the instruction to adjust the volume is an instruction to increase the volume, and the determined adjustment scheme of the voice input is an adjustment scheme that does not include a modifier corresponding to the instruction to adjust the volume;

Fourth, the instruction to adjust the volume is an instruction to increase the volume, and the determined adjustment scheme of the voice input is an adjustment scheme including a modifier corresponding to the instruction to adjust the volume.

FIG. 2 is a flowchart of a method for adjusting volume based on voice control provided by another embodiment of the present application. As shown in FIG. 2 , the method may be the above-mentioned first case, that is, the instruction to adjust the volume is an instruction to decrease the volume, and the determined adjustment scheme of the voice input does not include the corresponding instruction to adjust the volume The conditioning scheme of modifiers, including:

Step S21, judging whether the volume is within the first volume range;

For example, the application can firstly divide the overall volume range (ie, the minimum volume to the maximum volume) into a first volume range and a third volume range. For example, the minimum volume is 0 and the maximum volume is 39, then the first volume range can be 0 -19, which belongs to the range of volume that is psychologically acceptable to the user without damage to the user's ears when listening for a long time. The third volume is 20-39, in which the strong output power will increase the decibel value, which will cause certain damage to the human ear. It can be understood that any volume in the third volume range is greater than any volume in the first volume range. The examples below are also detailed in this hierarchy.

Step S22, when it is determined that the volume is within a first volume range, control the volume to decrease by a first preset value;

For example, still taking the overall volume range of 0-39 as an example, 0-39 can be divided into 40 grids, and the volume control can be adjusted based on these 40 grids, increasing or decreasing by 1 grid or multiple grids at a time. 0-39 can also be divided into multiple levels, for example, 8 levels, each 5 grid volume is a level, and the volume control can be adjusted based on these 8 levels, increasing or decreasing one level or more at a time. When the volume is in the first volume range, that is, for example, 0-19, the volume is controlled to decrease by a first preset value, and the first preset value may be, for example, 1 grid or 1 level.

Step S23, when it is determined that the volume is within a third volume range, the volume is controlled to decrease by a second preset value.

For example, since the overall volume range is divided into a first volume range and a third volume range, if it is not within the first volume range, it must be within the third volume range. Then, when the volume is within a third volume range, for example, 20-39, the volume is controlled to decrease by a second preset value. The second preset value is greater than the first preset value, for example, 5 grids or 5 levels.

FIG. 3 is a flowchart of a method for adjusting volume based on voice control provided by another embodiment of the present application. As shown in FIG. 3 , the method may be the above-mentioned second case, that is, the instruction to adjust the volume is an instruction to decrease the volume, and the determined adjustment scheme of the voice input is an instruction that includes a corresponding instruction to adjust the volume. Modification schemes for modifiers, including:

Step S31, judging whether the volume is within the first volume range;

Step S32, when it is determined that the volume is within the first volume range, control the volume to decrease by a third preset value;

For example, in this embodiment, when the volume is in the first volume range, that is, for example, 0-19, the volume is controlled to decrease by a third preset value, the second preset value is greater than the third preset value, and the third preset value is greater than The first preset value. For example, as described above, if the second preset value can be 5 grids or 5 levels, the first preset value can be 1 grid or 1 grid, then the third preset value can be 2 grids or 2 ranks.

Step S33, when it is determined that the volume is within a third volume range, control the volume to decrease by the second preset value.

For example, in this embodiment, when the volume is in a third volume range, such as 20-39, the volume is controlled to decrease by a second preset value, such as 5 bars or 5 levels.

FIG. 4 is a flowchart of a method for adjusting volume based on voice control provided by another embodiment of the present application. As shown in FIG. 4 , the method may be the above third case, that is, the instruction to adjust the volume is an instruction to increase the volume, and the determined adjustment scheme of the voice input does not include the corresponding instruction to adjust the volume The conditioning scheme of modifiers, including:

Step S41, judging whether the volume is within the second volume range;

Specifically, in this embodiment, a second volume range can also be set within the first volume range, that is, the volume comfort zone, where this range is a comfortable range acceptable to most people, and can be understood as the best listening zone, such as 5 -11.

Step S42, when it is determined that the volume is within the second volume range, control the volume to increase to a third preset value;

Specifically, when the volume is within the second volume range, the volume is controlled to increase by a third preset value, such as 2 bars or 2 levels.

Step S43, when it is determined that the volume is not in the second volume range, determine whether the volume is in the first volume range and is not in the third volume range after being increased;

For example, when the volume is not within the second volume range, there are two situations: one is within the first volume range but not within the second volume range, for example, at 0-4 or 12-19; Three volume ranges, eg at 20-39. If the volume is between 12 and 19, it may be in the third volume range after the increase. There are still different control methods for this, which needs to be judged.

Step S44, when it is determined that the volume is in the first volume range and is not in the third volume range after the increase, controlling the volume to increase by a first preset value;

For example, when the volume is in the first volume range, such as 0-4 or 12-19, and is not in the third volume range after the increase, for example, the volume is not in the 20-39 range after the increase, control the volume increase Large first preset value, ie 1 grid or 1 level.

Step S45, when it is determined that the volume is within the third volume range, or the volume is within the first volume range and is within the third volume range after being increased, reminding that the volume is too loud.

For example, when the volume is in the third volume range, such as 20-39, or although it is in the first volume range, such as 12-19, but after the volume is increased, it is in the third volume range, such as 20-39, then At this time, it is necessary to remind the user that the volume is too loud, and ask whether to adjust it. When receiving a positive answer from the user, you can control the volume to increase to the first preset value, such as 1 bar or 1 level; when receiving a negative answer, you can not adjust.

FIG. 5 is a flowchart of a method for adjusting volume based on voice control provided by another embodiment of the present application. As shown in FIG. 5 , the method may be the above fourth case, that is, the instruction to adjust the volume is an instruction to increase the volume, and the determined adjustment scheme of the voice input is an instruction that includes a corresponding instruction to adjust the volume. Modification schemes for modifiers, including:

Step S51, judging whether the volume is in the first volume range after the volume is increased;

Step S52, when it is determined that the volume is in the first volume range after the volume is increased, control the volume to increase the third preset value;

Specifically, after the volume is increased, the volume is in the first volume range, for example, it is still in the range of 0-19 after the volume is increased, and the volume is controlled to be increased by a third preset value, such as 2 bars or 2 levels.

Step S53, when it is determined that the volume is in the third volume range after the volume is increased, reminding that the volume is too loud.

For example, after the volume is increased, it is in the third volume range, such as 20-39 after the increase, then the user needs to be reminded that the volume is too loud, and ask whether to adjust it. When receiving a positive answer from the user, you can control the volume to increase The first preset value, such as 1 grid or 1 level; when a negative answer is received, no adjustment can be made.
