The agent always reads this as B2Billion. Is there a way to correct it to always say B-2-B? I tried few prompting techniques but dont see it working.

In deepgram transcriber there is keyword suppression/boost. You can try using it. https://developers.deepgram.com/docs/keywords

Ah there is a list of special words like this. I'll add it to the list!

Another one is ABM ... it currently doesnt sound right

We'll get these added as well

is there any way we can add this ourselves?
