Positioning using audio recognition
First Claim
1. A system comprising:
- a memory having stored thereon computer executable components; and
a processor configured to execute the following computer executable components stored in the memory;
a extraction component that extracts a set of interest points from an audio signal associated with an audio announcement;
a matching component that determines if the extracted set of interest points matches a set of interest points representative of an audio fingerprint in a data store comprising audio fingerprints; and
a location component that determines location information associated with the audio fingerprint based in part on the set of extracted interest points matching the set of interest points representative of the audio fingerprint in the data store.

Abstract
Systems and methods for determining location based on audio fingerprinting are disclosed. An extraction component extracts a set of interest points from an audio signal associated with an audio announcement. Then a matching component determines if the extracted set of interest points matches a set of interest points representative of an audio fingerprint in a data store comprising audio fingerprints. In an aspect, the audio fingerprints in the audio fingerprint data store represent announcements for underground transportation systems. A location component further determines location information associated with the audio fingerprint based in part on the set of extracted interest points matching the set of audio interest points representative of the audio fingerprint in the data store.
