Embodiment 1

[0058] An embodiment of the present invention provides a method for identifying a speaker in a video conference, which can be used in a device for identifying a speaker in a video conference, such as figure 1 As shown, the method includes the following steps:

[0059] Step S11, acquiring the audio volume of each participating site.

[0060] The speaker's identification device in the video conference obtains the audio volume of all participating sites, that is, obtains various sounds from all participating sites, including the voice of the speaker, the noise of the site, or other disturbing sounds.

[0061] Step S12, determine the site picture where the speaker is located according to the audio volume.

[0062] The identification device of the speaker in the video conference can determine the scene where the speaker is located according to the size of the audio volume, and can also determine the scene where the speaker is located according to the combination of the audio volum...

Embodiment 2

[0071] An embodiment of the present invention provides a method for identifying a speaker in a video conference, which can be used in a device for identifying a speaker in a video conference, such as figure 2 As shown, the method includes the following steps:

[0072] Step S21, acquiring the audio volume of each participating site.

[0073] It is the same as step S11 in Embodiment 1, and will not be repeated here.

[0074] Step S22, determine the site picture where the speaker is located according to the audio volume.

[0075] The speaker's identification device in the conference system uses the audio volume and the voice information of the conference site to determine the screen of the conference site where the speaker is located. Specifically include the following steps:

[0076] In step S221, the voice information of each participating site is acquired.

[0077] The speaker identification device in the conference system can be obtained by acquiring the audio informatio...

Embodiment 3

[0105] An embodiment of the present invention provides a method for identifying a speaker in a video conference, which can be used in a device for identifying a speaker in a video conference, such as image 3 As shown, the method includes the following steps:

[0106] Step S31, acquiring the audio volume of each participating site.

[0107] It is the same as step S21 in Embodiment 2, and will not be repeated here.

[0108] Step S32, determine the site picture where the speaker is located according to the audio volume.

[0109] It is the same as step S22 in Embodiment 2, and will not be repeated here.

[0110] Step S33 , marking the frame of the conference site picture of the speaker as a preset color of initial brightness, wherein each participating site corresponds to a conference site picture.

[0111] It is the same as step S23 in Embodiment 2, and will not be repeated here.

[0112] Step S34, control the brightness of the marked preset color to gradually increase accor...

Abstract

The invention discloses a method and device for marking a speaker in a video conference, wherein the method includes: obtaining the audio volume of each conference site; determining the conference screen where the speaker is located according to the audio volume; marking the frame of the conference screen of the speaker with a preset color of initial brightness, wherein each conference site corresponds to one conference screen; gradually increasing, according to a preset gradual change rule, the brightness of the marked preset color to the target color brightness. The brightness of the frame color of the conference screen where the speaker is located is adjusted according to the preset gradual change rule. Since the adjustment of the color brightness is a gradual change so that the brightness of the frame color of the conference screen is not very high when an abnormal sound ends because the abnormal sound is generally short. Thus, the attention of the conference participants is not called and the speaker in the video conference is highly accurately marked.

Description
