The Speaker of the House
The speaker of the United States House of Representatives, commonly known as the speaker of the House, is the presiding officer of the United States House of Representatives. The office was established in 1789 by Article I, Section 2 of the U.S. Constitution. The speaker is the political and parliamentary leader of the House of Representatives and is simultaneously the House's presiding officer, de facto leader of the body's majority party, and the institution's administrative head. Speakers also perform various other administrative and procedural functions. Given these several roles and responsibilities, the speaker usually does not personally preside over debates. That duty is instead delegated to members of the House from the majority party. Neither does the speaker regularly participate in floor debates.
The Constitution does not require the speaker to be an incumbent member of the House of Representatives, although every speaker thus far has been. The speaker is second in the United States presidential line of succession, after the vice president and ahead of the president pro tempore of the Senate.
众议院议长
美国众议院议长，俗称众议院议长，是美国众议院的议长。该办公室于 1789 年根据美国宪法第一条第二款设立。议长是众议院的政治和议会领袖，同时也是众议院的议长、该机构多数党的实际领导人和该机构的行政首长。演讲者还履行各种其他行政和程序职能。鉴于这几个角色和职责，演讲者通常不会亲自主持辩论。相反，这项职责由多数党委派给众议院议员。演讲者也不经常参加现场辩论。
宪法并不要求议长必须是众议院的现任议员，尽管迄今为止每位议长都是如此。议长是美国总统继任者中的第二位，在副总统之后，在参议院临时议长之前。
