I'm using Azure Speech Services with the language set to UK English, and I've noticed two recurring transcription issues:
When I dictate the word "draft", it consistently transcribes as "draught", even when the context clearly favors "draft" (e.g., referring to a document).
When I dictate the currency symbol "£", it often transcribes as "lbs", despite the surrounding context making it clear that it's referring to currency.
Has anyone else experienced this? Is there a way to improve recognition accuracy for these kinds of context-sensitive terms, or customize the transcription model to better handle such cases?

in below mic input statement
"Drafted a 15 pounds bill and sent to my sister", yes saw presence of lbs in first few trials with Real time speech service
Attached screenshot for reference.
It might be a phonetics/pronunciation issue, please confirm the speech service in usage and share the audio in private chat for verification.
Thank you.

Thank you.
