"The more you use Dictation, the better it understands you. Dictation learns the characteristics of your voice and adapts to your accent."
I have found this not to be the case, in fact quite the opposite, no matter how I may say a word it keeps giving me the incorrect word. For example 'Faith' will always come back as 'face'. 'End' always as 'and', etc.
As far as I can tell there is no way to correct these errors on the server? So how can it better understand me if it cannot be corrected?
