METHODS AND ELECTRONIC DEVICES FOR DETERMINATION OF INTENT ASSOCIATED WITH UTTERED UTTERANCE OF USER

摘要

A method and server for determining an intent associated with a spoken user utterance are disclosed. The method includes determining at least one speech unit where each speech unit has textual data representative of a word or pause and has a corresponding segment of the digital audio signal. For each speech unit, the method includes generating a respective textual feature, generating a respective acoustic feature vector and generating a respective enhanced feature vector. The method also includes employing a neural network (NN) configured to determine the intent of the spoken user utterance by inputting into the NN the enhanced feature vectors. The NN has been trained to estimate a probability of the intent being of a given type.
