1. A method of capturing an address from a caller via a telephone interface, said method comprising:
- setting a grammar;
audibly prompting said caller to provide an utterance representing said address;
receiving said utterance via said telephone interface;
verifying said utterance using said grammar; and
if said utterance matches multiple entries of said grammar, identifying said utterance from said multiple entries using a relative size threshold, wherein said identifying comprises;
determining a relative size of each street name entry matching said utterance;
determining whether said relative size threshold is exceeded by relative size of any of street name entries; and
if said relative size threshold is exceeded by relative size of a particular street name entry, selecting said particular street name entry.

5. A method of delivering audio driving directions via a telephone interface, said method comprising:
-
capturing an origin address and a destination address inputted by a caller via said telephone interface; generating raw driving directions based on said origin and destination addresses; generating formatted driving directions from identifying a maneuver in said raw driving directions;
wherein the maneuver comprises at least one of a merge-type, turn-type, and exit-ramp type;wherein said generating formatted driving directions comprises; removing one or more redundant steps from said raw driving directions; replacing one or more first steps from said raw driving directions; consolidating one or more second steps from said raw driving directions; and renumbering said steps of said raw driving directions to form said formatted driving directions; generating said audio driving directions based on said formatted driving directions; and playing to said caller said audio driving directions in response to a command provided by said caller.

6. A voice portal comprising:
-
a processor; a memory for storing therein instructions which when executed perform a method of capturing an address from a caller via a telephone interface, said method comprising; setting a grammar; audibly prompting said caller to provide an utterance representing said address; receiving said utterance via said telephone interface; verifying said utterance using said grammar; and if said utterance matches multiple entries of said grammar, identifying said utterance from said multiple entries using a relative size threshold, wherein said identifying comprises; determining a relative size of each street name entry matching said utterance;
determining whether said relative size threshold is exceeded by relative size of any of street name entries; andif said relative size threshold is exceeded by relative size of a particular street name entry, selecting said particular street name entry. - View Dependent Claims (7, 8, 9)
