Azure speech to text. Is it possible to replace some phrases with another?

Question

Hi there,

I am trying to enhance speech to text translation with PhraseListGrammar so it gives me preferred variant of phrases like e.g in de-DE instead of dreieinhalb Stunden to be recognized as 3:30 Stunden, or circa to be recognized as ca instead. I've tried detailed output, ITN version of it, to be precise, however it has identical output.

Is there any other, inbuilt, way then actually search through resulted text for phrases and replace it with preferred once?
Thank you in advance for the support.

@Diakulych Mykola Phraselist provides a way to enhance the recognition accuracy, in this case are you trying to replace words of recognized text in the output? If that is the case, I think you would need to use custom speech model as phraselist can help in recognition of words that could be misinterpreted from speech. As in the example below from documentation:

For example, let's say that you want the Speech service to recognize this sentence: "Hi Rehaan, this is Jessie from Contoso bank. " After testing, you might find that it's incorrectly recognized as: "Hi everyone, this is Jesse from can't do so bank." In this case you would want to add "Rehaan", "Jessie", and "Contoso" to your phrase list. Then the names should be recognized correctly.
