It’s not enough to have only a valuable message to engage an audience. Without high intelligibility, an effective speech can become impotent. In places of academic, conferences and seminars and houses of senate, systems with clear spoken word and the ability to cover a large area uniformly is the key to continuing the conversation. With the rapid growth of globalization, communicating to client, colleague or vendor in overseas has been more prevalent and with that said, using a video conferencing system that compatible with communication applications like Zoom, Googlemeet, Microsoft team or Skype will be very helpful.
