The speaker of a deliberative assembly, especially a legislative body, is its presiding officer, or the chair. The title was first used in 1377 in England.
The title was first recorded in 1377 to describe the role of Thomas de Hungerford in the Parliament of England.
The speaker's official role is to moderate debate, make rulings on procedure, announce the results of votes, and the like. The speaker decides who may speak and has the powers to discipline members who break the procedures of the chamber or house. The speaker often also represents the body in person, as the voice of the body in ceremonial and some other situations.
By convention, speakers are normally addressed in Parliament as 'Mister Speaker' if a man, or 'Madam Speaker' if a woman. In other cultures, other styles are used, mainly being equivalents of English "chairman" or "president". Many bodies also have a speaker pro tempore (or deputy speaker), designated to fill in when the speaker is not available.
The speaker is commonly supported by a 'speaker's office'.
Examples of speakers include:
The president of the National Assembly of Armenia is the speaker of the house in the National Assembly of Armenia. The formation of this position was established on 1 August 1918.
The speaker of the House of Representatives is the presiding officer of the Australian House of Representatives, the lower house of the Parliament of Australia. The president of the Senate is the presiding officer of the Australian Senate, the upper house of the Parliament.
