Abstract: Enhanced speech recognition accuracy is provided by using geographic data, illustratively related to the geographic location of a mobile device, to automatically select a subset of words for use with a speech recognition procedure. The subset of words is selected from an element database including words that describe elements at each of a plurality of locations. Geographic data includes at least one of global positioning system (GPS) position data, cell identity (Cell-ID) data, caller identification (Caller ID) data, place name data, or zip code data. Elements include at least one of street names, businesses, merchants, points of interest, transportation facilities, individual households, activities, and landmarks. By selecting a subset of words, the total number of words used in the speech recognition procedure is substantially reduced, thereby improving speech recognition accuracy.

Abstract translation: 通过使用与移动设备的地理位置相关的地理数据来提供增强的语音识别精度，以自动选择用于语音识别过程的单词的子集。 从包括在多个位置中的每一个处描述元素的单词的元素数据库中选择单词的子集。 地理数据包括全球定位系统（GPS）位置数据，小区标识（小区ID）数据，呼叫者识别（来电显示）数据，地名数据或邮政编码数据中的至少一个。 要素包括街道名称，企业​​，商人，兴趣点，交通设施，个人住户，活动和地标中的至少一个。 通过选择一个单词子集，语音识别过程中使用的单词总数大大减少，从而提高了语音识别精度。
