摘要：
A method of identifying a location of a query string in an audio signal is provided. Under the method, a segment of the audio signal is selected. A score for a query string in the segment of the audio signal is determined by determining the product of probabilities of overlapping sequences of tokens. The score is then used to decide if the segment of the audio signal is likely to contain the query string.
