口头表决，又称为声音表决（voice vote），一般是指立法机构采取的表决方式。 口头表决，被认为是最简单、最快捷的表决进程。主持人通常会向大会提问，要求赞成的说“是”或“赞”，然后要求反对者说“不”，最后估计结果。一般用于情况比较明确的表决进程。如果两方非常接近，则需要更加精确的表决方式，如起立表决，或者投票表决。

In parliamentary procedure, a voice vote (or viva voce, from the Latin, "live voice") is a voting method in deliberative assemblies (such as legislatures) in which a vote is taken on a topic or motion by responding verbally.

The voice vote, or acclamation, is considered the simplest and quickest of voting methods used by deliberative assemblies. The presiding officer or chair of the assembly will put the question to the assembly, asking first for all those in favor of the motion to indicate so verbally ("aye" or "yes"), and then ask second all those opposed to the motion to indicate so verbally ("nay" or "no"). The chair will then make an estimate of the count on each side and state what he or she believes the result to be. Since in close cases this can be imprecise, typically if there is any doubt as to the outcome any member of the assembly may request another vote by a method such as division of the assembly (a standing or rising vote), or a roll call vote. Voice votes are usually not recorded, while others are.
