One participant is regarded as one speaker if the one participant speaks longer than the reference time.

The video switching system calculates an image switching frequency, and determines whether to switch to a video image of the main speaker according to the image switching frequency. The video switching system calculates a response time if determining to switch to the video image of the main speaker, and adjusts the reference time according to the image switching frequency and the response time.
