Claim 1:
2. The computer-implemented method of claim 1, wherein training the model update object comprises:
performing first training of the model update object using the first speech processing model and the second dataset to determine second values for the model update object;
determining a first subset of the second values to replace with first null values;
performing second training of the model update object using the first speech processing model and the second dataset to determine third values for the model update object, wherein the first null values are unchanged during the second training;
determining a second subset of the third values to replace with second null values, wherein the second subset is a superset of the first subset and larger than the first subset; and
performing third training of the model update object using the first speech processing model and the second dataset to determine the first values for the model update object, wherein the second null values are unchanged during the third training.
