translation.en: Or who say, don't spend all your budget on a huge screen in the conference room, and then place one tiny microphone in the middle of a table for 30 people.  If you can hear me, you can understand me without seeing me. If you can see me without hearing me, that does not work.
translation.zh: 有人说，别花太多钱 在会议室的屏幕上， 然后在30人的大桌中央 放一个微型麦克风。 如你听见我，不须看到我 也会明白我。如你只看到我却听不清我， 这是不奏效的。
