Vapi Assistant Keeps saying "zero" in place of "o"

I am having an issue where my Vapi assistant keeps saying 0 instead of o. For example if I say the last name Moore, it interprets it as M o 0 r e.

I've tried everything I know in Vapi API. Deepgram keywords, ElevenLabs pronuciation dictionaries, prompting directly in my assistant prompt. This only happens with double Os. (o o)

Call IDs:
1bd09f8c-8b8b-49de-b90a-8ba2adf9d7e9
da3fcd6a-f79f-4d58-bcbb-2d2cd217e3c0

I don't have my own Deepgram API key, I am just using the one available with Vapi and the settings available via Vapi's API.

I do not have smart formatting on, nor numerals. No format plan on as well. Please assist as soon as possible. Thank you!
