Abstract
Speech recognition in mobile processor-based devices may be improved by using location information. Location information may be derived from on-board hardware or from information provided remotely. The location information may assist in a variety of ways in improving speech recognition. For example, the ability to adapt to the local ambient conditions, including reverberation and noise characteristics, may be enhanced by location information. In some embodiments, pre-developed models or context information may be provided from a remote server for given locations.
