Speech recognition software in a telephone or telephone network recognizes a non-numeric word identifying a location, and a telephone number spoken by a user. The speech recognition grammar specifies locations and optionally constraints, such as the length, for telephone numbers in those locations. Locations may consist of countries, cities, communication network names, or any combination thereof. A database containing information about locations and telephone numbers may be used to determine whether the recognized telephone number could exist at the recognized location. Once an phone number has been identified, the user is asked to confirm the location and telephone number. If confirmed, an access code, country code or city code corresponding to the recognized location is dialed after a prefix, if needed, and is followed by the recognized telephone number. This is particularly useful for international locations to reduce the number of digits that must be recognized.
