1. A computer-implemented method comprising:
receiving, by a landmark identification module, speech instructions describing an intended autonomous vehicle (AV) destination, and wherein the speech instructions comprise Global Positioning System (GPS) coordinate metadata associated with the AV destination;
retrieving from a map database, by the landmark identification module, a plurality of map labels;
determining, by the landmark identification module, a probability that the AV destination is located within a region of a map associated with each of the plurality of map labels;
segmenting, by the landmark identification module, the plurality of map labels based on geolocation metadata and the GPS coordinate metadata associated with the AV destination;
analyzing the speech instructions to identify one or more landmarks associated with the described AV destination; and
determining an AV destination based on the determined probabilities for each of the plurality of map labels and the one or more landmarks associated with the described AV destination.
