First Claim
Patent Images
1. A method comprising:
- accepting query data from one or more spoken instance of a query;
processing the query data including determining a representation of the query that defines multiple sequences of subword units each representing the query; and
locating putative instances of the query in input data from an audio signal.

Abstract
An approach to wordspotting (180) using query data from one or more spoken instance of a query (140). The query data is processed to determining a representation of the query (160) that defines multiple sequences of subword (130) units each representing the query. Then putative instances of the query (190) are located in input data from an audio signal using the determined representation of the query.

17. Software stored on a computer-readable medium comprising instructions for causing a processing system to:
-
accept query data from one or more spoken instance of a query;
process the query data including determining a representation of the query that defines multiple sequences of subword units each representing the query; and
locate putative instances of the query in input data from an audio signal.

18. A system comprising:
-
a speech recognizer for processing query data from one or more spoken instances of a query;
a data storage for receiving a data representation of the query from the speech recognizer, the data representation defining multiple sequences of subword units representing the query;
a word spotter configured to use the data representation of the query to locate putative instances of the query in input data from an audio signal.
