Classification: CPC G | IPC G

Claim 12:
13. A system, comprising:
at least one processor; and
at least one memory comprising instructions that, when executed by the at least one processor, cause the system to:
receive a first portion of audio data;
receive a second portion of audio data;
process, using a recurrent neural network (RNN), a first portion of audio data to generate first data representing a first hidden state of the RNN;
process the first data to determining a first variable value;
determine second data representing a first embedding using at least the first data;
process, 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;
determine, using the third data, a second variable value;
determine fourth data representing a second embedding using the third data and the first embedding; and
determine, using at least the fourth data and the second variable value, fifth data representing audio features representing the audio data.
