Problems solved by technology

However, this solution also has disadvantages. If the English venue speaks, the translator translates it into Chinese, and each venue will hear English first, and then Chinese. But in fact, the Chinese venue does not need to hear the English speech, and the English There is also no need to hear the translated Chinese speeches, which makes the participants have to hear a lot of useless information. Chinese and English are mixed, which makes the meeting order chaotic, and the participants are prone to fatigue, and the translation process will slow down the meeting rhythm , the efficiency decreases

If you consider that there may be three or more languages ​​in the conference, and there may be multiple venues speaking at the same time, considering the effect after the audio mixing, the above two solutions will lead to poor conference quality and cannot be applied
