Optionally, each default corresponding first default volume of frequency range may be the same or different.
Optionally, since low frequency speech components are used to be promoted the reduction degree and identification of voice sound, High frequency speech component is used
In the reproducibility for promoting information, hence, it can be determined that low frequency speech components and the corresponding first default volume of High frequency speech component
The first default volume corresponding more than intermediate frequency speech components, that is, the amplitude that low frequency speech components and High frequency speech component are reduced
It is smaller, this way it is possible to avoid voice is distorted after adjusting.
For example, the correspondence of default frequency range and the first default volume can be as shown in table 1：
Table 1
| Default frequency range | First default volume |
| 100Hz-1KHz | 130 decibels |
| 1KHz-4KHz | 110 decibels |
| 4KHz-8KHz | 130 decibels |
As shown in Table 1, when the distance between speech player and barrier are equal to the first pre-determined distance, by speech play

Second of possible situation：The distance between speech player and barrier are less than the first pre-determined distance.
In that case, according to the distance between speech player and barrier, determine that each default frequency range is corresponding
Volume reduction amount presets the corresponding first default volume of frequency range and volume reduction amount according to each, reduces speech player and broadcasts
The corresponding volume of frequency range is each preset in the audio put.
Optionally, determine that the process of each corresponding volume reduction amount of default frequency range is identical, in the following, to determine that first is pre-
If being illustrated for the process of the volume reduction amount of frequency range：
The corresponding second default volume of the first default frequency range is obtained, the second default volume is speech player in loud speaker mould
The effective volume of minimum under formula, when playing the audio of the first default frequency range, according to the distance between speech player and barrier,
First pre-determined distance, the corresponding first default volume of the first default frequency range and the second default volume, determine the first default frequency range pair
The volume reduction amount answered.
Optionally, each default corresponding second default volume of frequency range may be the same or different.
Optionally, since low frequency speech components are used to be promoted the reduction degree and identification of voice sound, High frequency speech component is used
In the reproducibility for promoting information, hence, it can be determined that low frequency speech components and the corresponding second default volume of High frequency speech component
The second default volume corresponding more than intermediate frequency speech components, that is, the amplitude that low frequency speech components and High frequency speech component are reduced
It is smaller, this way it is possible to avoid voice is distorted after adjusting.
For example, the correspondence of default frequency range and the second default volume can be as shown in table 2：
Table 2
| Default frequency range | Second default volume |
| 100Hz-1KHz | 70 decibels |
| 1KHz-4KHz | 50 decibels |
| 4KHz-8KHz | 70 decibels |
It should be noted that table 2 only illustrates the correspondence for presetting frequency range and the second default component in exemplary fashion,
Not to the restriction of the correspondence, in actual application, the correspondence is can be set according to actual needs, the present invention
Embodiment is not especially limited this.
It optionally, can be according to the corresponding volume reduction amount of first default frequency range of the determination of following formula one：
Wherein, Δ y is the corresponding volume reduction amount of the first default frequency range, y1It is preset for the first default frequency range corresponding first
Volume, y2For the corresponding second default volume of the first default frequency range, h1For the first pre-determined distance, h2For speech player and obstacle
The distance between object.
It optionally, can be with after determining and obtaining the corresponding first default volume of the first default frequency range and volume reduction amount
By the difference of the corresponding volume adjustment of the first default frequency range to the first default volume and volume reduction amount.
In the embodiment shown in fig. 3, different volume adjustments is carried out to the volume of different frequency range so as to low frequency voice
The amplitude that component and High frequency speech component reduce is smaller, this way it is possible to avoid voice is distorted after adjusting.
In the following, by specific example, technical solution shown in the application is described in detail.
Illustratively, it is assumed that the correspondence such as table 3 of the default frequency range of division and the first default volume, the second default volume
It is shown：
Table 3
| Default frequency range | First default volume | Second default volume |
| 100Hz-1KHz | 130 decibels | 80 decibels |
| 1KHz-4KHz | 110 decibels | 50 decibels |
| 4KHz-8KHz | 130 decibels | 80 decibels |
Assume again that the first pre-determined distance is 10 centimetres, the broadcasting sound of the speech player of terminal device in loudspeaker mode
Amount is 180 decibels.
In actual application, when the speech play pattern of speech player is speaker mode, when detecting language
When sound player is equal to the first pre-determined distance at a distance from barrier (such as human ear), then directly by the language of 100Hz-1KHz frequency ranges
The decibel value of cent amount is adjusted to 130 decibels, and the decibel value of the speech components of 1KHz-4KHz frequency ranges is adjusted to 110 decibels, will
