Claim 4:
5. A method comprising:
receiving a first portion of audio data;
receiving a second portion of audio data;
processing, using a recurrent neural network (RNN), the first portion of audio data to generate first data representing a first hidden state of the RNN;
processing the first data to determining a first variable value;
determining second data representing a first embedding using at least the first data;
processing, using the RNN, the second portion of audio data and the first data to generate third data representing a second hidden state of the RNN;
determining, using the third data, a second variable value;
determining fourth data representing a second embedding using the third data, and the first embedding; and
determining, using at least the fourth data and the second variable value, fifth data representing audio features representing the audio data.
