Claim 18:
19. A computer-implemented method comprising:
receiving first audio;
determining, using a Long Short-Term Memory (LSTM) model and a portion of the first audio, first audio embedding data corresponding to the first audio;
processing the first audio embedding data using a logistic regression model to determine that the first audio corresponds to machine-outputted audio;
in response to determining that the first audio data corresponds to machine outputted audio, storing the first audio data;
after receiving the first audio, receiving, by the device, second audio;
determining, using the LSTM model and a portion of the second audio, second audio embedding data corresponding to the second audio;
determining, using the second audio embedding data, that the second audio corresponds to non-machine-outputted audio;
in response to determining that the second audio corresponds to non-machine-outputted audio, processing the second audio embedding data using an automatic speech recognition (ASR) component to determine first ASR data corresponding to a spoken user input represented in the second audio;
determining, using the first ASR data and content represented in the first audio, that the spoken user input relates to the first audio;
determining, using the first ASR data and the first audio, first output data responsive to the spoken user input; and
causing presentation of the first output data.
