Sectioned memory networks for online word-spotting in continuous speech

摘要

Systems, methods, and computer program products to detect a keyword in speech, by generating, from a sequence of spectral feature vectors generated from the speech, a plurality of blocked feature vector sequences, and analyzing, by a neural network, each of the plurality of blocked feature vector sequences to detect the presence of the keyword in the speech.

主权项

1. A method to detect a keyword in speech, comprising:
generating, from a sequence of spectral feature vectors generated from the speech, a plurality of blocked feature vector sequences, wherein each of the plurality of blocked feature vector sequences comprises a respective subset of the plurality of feature vectors, wherein each of the plurality of blocked feature vector sequences overlap adjacent blocked feature vector sequences by a predefined count of feature vector sequences; and analyzing, by a neural network executing on one or more computer processors, each of the plurality of blocked feature vector sequences to detect the presence of the keyword in the speech.
