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.
