    • Method and apparatus for multi-pass speech recognition. An input device receives spoken input. A processor performs a first pass speech recognition technique on the spoken input and forms first pass results. The first pass results include a number of alternative speech expressions, each having an assigned score related to the certainty that the corresponding expression correctly matches the spoken input. The processor selectively performs a second pass speech recognition technique on the spoken input according to the first pass results. Preferably, the second pass attempts to correctly match the spoken input to only those expressions which were identified during the first pass. Otherwise, if one of the expressions identified by the first pass is assigned a score higher than a predetermined threshold (e.g., 95%), the second pass is not performed. Because the second pass is performed only when necessary, the invention recognizes speech with a faster average speed for a given accuracy in comparison to prior systems.
    • 用于多遍语音识别的方法和装置。 输入设备接收口头输入。 处理器在口头输入端执行第一遍语音识别技术，并形成第一遍的结果。 第一遍结果包括多个替代语言表达，每个具有与相应表达正确匹配口语输入的确定性相关的分配分数。 处理器根据第一遍的结果选择性地在口头输入上执行第二遍语音识别技术。 优选地，第二遍尝试将口头输入正确地匹配到在第一遍期间被识别的那些表达。 否则，如果由第一遍识别的表达式中的一个被分配高于预定阈值（例如，95％）的分数，则不执行第二遍。 因为仅在必要时执行第二遍，所以与现有系统相比，本发明以给定精度更快的平均速度识别语音。

Alternately, the first pass results identify a characteristic of the spoken input. The characteristic can be the gender of the speaker or a type of telephone the speaker is calling from. In which case, the second pass speech recognition technique is selected from a plurality of speech recognition techniques according to the characteristic identified by the first pass. Because the selected second pass technique is specific to the characteristic of the spoken input, the second pass technique can perform speech recognition faster for a given accuracy than a technique which is not specific.

    • Advertisements are selected for display on search results pages or web pages displaying requested content. A request associated with a user is received for an advertisement, such as for display on a search results page or a content-displaying web page. Profile information associated with the user is identified. An inverted index is queried based on the identified profile information. The inverted index includes a list of user attributes and a list of at least one advertisement and corresponding weight factor that correspond to each listed user attribute. A plurality of advertisements is determined in the inverted index based on the query. The determined advertisements are filtered to generate an advertisement presentation configuration that includes at least one of the identified advertisements.
