對講機的英文怎麼說 (有分大廈對講機跟手持對講機兩種...)
雖然在中文都是對講機，但是在英文裡大樓用的對講機跟無線電對講機 通常用不同的單字。
intercom
interphone
talkback
doorphone
a set of communications devices that allows people in different parts of a building, aircraft, ship, etc., to speak to each other. (cambridge dictionary)
walkie talkie
two-way radio
為什麼會有walkie talkie這種奇怪的名字呢，我想應該是沿用當初產品名稱吧，上面這段有提到無線對講機是第二次世界大戰時開發的。另外首部被命名為Walkie-Talkie的無線電對講機就是Motorola SCR-300。
