Lecture background matching method and apparatus

Abstract

In the embodiment, the invention discloses a method for matching speech background and a device for carrying out the same. The method comprises the following steps of: identifying speech characteristics of a speaker and generating a speech characteristic parameter of the speaker; matching the speech characteristic parameter with a background characteristic parameter of a background material; and selecting the corresponding background material to play according to the matching result. With the invention, the problems of filtering and screening the background which conforms to meaning or emotion or body language of the speaker in an automatic switching process of an improvisational speech background are solved, thereby achieving the aim of matching speech effect by automatically changing the background and improving background auxiliary effect of the improvisational speech for the speaker.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a speech background matching method and device. Background technique [0002] In current conferences, especially in conference video systems and related communications, there are mainly two types of speech methods: one is that the speaker prepares in advance and speaks on a certain topic or content; the other is that the speaker does not prepare in advance Make relevant preparations and impromptu speeches on a topic. The former can use pre-customized background materials during the speech process, such as demo films, music, video animation, special effects (light changes, lasers, smoke, flames, fountains, water curtains), etc., to match the speech process and strive to achieve Better speech effect; and the latter cannot be customized in advance due to the randomness of time and content in the speech process, so the background material is difficult to follow the sp...

AI Technical Summary

Problems solved by technology

[0003] In an impromptu speech, the relatively fixed background material lacks timely tracking of the speech content, which will have a negative impact on the speech effect; the speaker himself manually switches the background according to the speech process, which requires the speaker to pause the speech or pause the thinking process when the speech is suspended , which is very unfavorable for the speaker to accurately express his speech content; and the speech partner manually switches the background according to the speech process, which requires the speech partner to manually understand the speech content. Once the speech partner's understanding of the speech content is biased , the background switching will not be able to effectively cooperate with the speech process
