I am developing a speech to text solution using Azure Custom Speech API as a backend. I noticed the drop in the quality of custom trained models.
Previously, I was kind of impressed by the result of a custom trained model where I can train with Text data or Text associated with voice prompt.
The previous training usually took 45-60 minutes and the result is very good the model can pick up words with high accuracy.
However, recently I found that it took less than 10 minutes to train a model and the quality of the trained model is not there.
So, Could you please advise how to revert back to the previous algorithm? I would rather not trade off on training time vs model quality.
