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

The voice vote 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 orally ("aye" or "yea"), and then ask second all those opposed to the motion to indicate so verbally ("no" or "nay"). The chair will then make an estimate of the count on each side and state what they believe the result to be.

Voice votes have inherent disadvantages and the method has major shortfalls in close contests. The volume of the voices are typically only estimated and not actually measured with sound level meters, giving a chair enough plausible deniability to falsify the result if they disagree with it; even if such a vote can be objectively quantified in terms of decibels, the method gives an unfair advantage to those who have louder voices. The need to make an audible signal also compromises any situation in which a secret ballot may be desired. The method is suitable in most cases where unanimity is required. 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, but sometimes are.

Voice votes are also used in non-governmental settings, such as battles of the bands and spectator sports where a most valuable player, Man of the Match or Best in Show award is chosen by the audience.
