Floor speaker既中文係咩?

Floor speaker in a debate

辯論的程序內, 正反方主、副辯論員(speakers)發言後,便是台下觀眾發問時間, 由台下發言者/台下發問者(floor speakers)發問, 台上答辯。( After all four speakers have spoken the debate will be opened to the floor, in which members of the audience will put questions to the teams. )

辯論中,台下發問者是floor speaker較合適的中文叫法,清楚說明他做甚麽。

Floor speaker 未必會問問題，發表意見亦可。
「台下發言人」較貼切。
