I have trained the Pronunciation model on Cognitive Service Speech Studio, but after training the Error Rate of trained model has increased from
Base Model - error rate (27.59% , model = (20201019))
Trained Model- error rate (31.47% )

Dataset used for training is English statements read by person in Indian Accent. This dataset is free of errors.

I want to know the reason behind this error increase.
