Patent ID: 11862146
Assignee: ASAPP, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. A system, comprising:
at least one server computer comprising at least one processor and at least one memory, the at least one server computer configured to:
receive a sequence of feature vectors computed from an audio signal;
compute a first stream vector by processing the sequence of feature vectors in a first stream, wherein the first stream comprises a first convolutional neural network layer having a first dilation rate;
compute a second stream vector by processing the sequence of feature vectors in a second stream, wherein the second stream comprises a second convolutional neural network layer having a second dilation rate, wherein the second stream does not include a layer with the first dilation rate, and wherein the second stream processes the sequence of feature vectors in parallel with the first stream; and
compute a vector of speech unit scores by processing the first stream vector and the second stream vector.
