The host of the meeting should have a loud and powerful voice and a variety of intonation(hui yi zhu chi yao sheng yin xiang liang you li yu diao fu you bian hua )

It is the most basic requirement for the presiding person to preside over the meeting and let every participant hear his voice. For larger meetings, microphone, loudspeaker and other tools can be used. As the "leader", the conference moderator should speak with strength, loud voice, clear speech, appropriate rhythm, and show self-confidence and upward force in his voice. He should not be powerless, or plain and lack of vitality. Through the change of intonation, the presider of the meeting expressed various ideas and emotions, which resonated with the participants, making his speech more infectious and shocking. A solemn and serious meeting requires a gentle and dignified tone; a cheerful and relaxed meeting requires a light and fluent tone.
