Abstract: A method includes receiving a spoken utterance that includes a plurality of words, and generating, using a neural network-based utterance classifier comprising a stack of multiple Long-Short Term Memory (LSTM) layers, a respective textual representation for each word of the of the plurality of words of the spoken utterance. The neural network-based utterance classifier trained on negative training examples of spoken utterances not directed toward an automated assistant server. The method further including determining, using the respective textual representation generated for each word of the plurality of words of the spoken utterance, that the spoken utterance is one of directed toward the automated assistant server or not directed toward the automated assistant server, and when the spoken utterance is directed toward the automated assistant server, generating instructions that cause the automated assistant server to generate a response to the spoken utterance.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving audio data encoding an utterance; obtaining an intermediate transcription of the utterance; before a final transcription of the utterance is obtained: i) determining that the intermediate transcription of the utterance is associated with a previously received search query, ii) obtaining one or more results that are identified as responsive to the previously received search query, and iii) storing one or more of the results; obtaining the final transcription of the utterance; determining that the final transcription of the utterance is also associated with the previously received search query; and in response to determining that the final transcription of the utterance is also associated with the previously received search query, providing the stored one or more results for output.
