Estimating the term…
A speech recognition input interface for a portable computing device is disclosed that limits the geographic references in a speech recognition vocabulary, such as street names, local landmarks and points of interest, to those geographic references that are within a predefined distance of the current location of a user. The predefined distance may be varied, for example, in accordance with the expected range of a user. Thus, the present invention provides a vocabulary containing only those entries that are most likely to be utilized by the speech recognition system, based on the current location and expected range of the user. A navigation system uses an improved speech recognition interface in conjunction with a position location device that determines a current location of a user within a geographic domain. A limiting process generates a navigational vocabulary containing geographic references that are most likely to be utilized, in order to improve the accuracy of the speech recognition interface.
