Claim 20:
21. The computing system of claim 19, the one or more speech enhancement model parameters being updated by:
identifying one or more labeling errors in the noise-suppressed transcription outputs;
calculating a cross-entropy loss based on the one or more labeling errors identified in the noise-suppressed transcription outputs;
performing a backpropagation of the cross-entropy loss to the speech enhancement model, the one or more speech enhancement model parameters being updated to optimize the noise-suppressed speech outputs to minimize an occurrence of labeling errors in the noise-suppressed transcription outputs;
calculating a phase-aware loss based on the second comparison; and
performing a backpropagation of the phase-aware loss to the speech enhancement model, the one or more speech enhancement model parameters being updated to optimize the noise-suppressed speech outputs to minimize a signal quality loss in the noise-suppressed speech outputs.
