You have not given us enough information in order to tell if she is a scammer or not.
Where did you meet? What is her exact profile link in the address bar?
Did she approach you, or did you make contact first? What "threw you off guard" about her voice, or was it something she said? What was the conversation? Did she email you? Can you post it if so, deleting your personal information from it?
Have you read these posts about how they work? See any red flags?
