I used

voiceId := "en-US-EmmaNeural"

as my azure voiceId but it returns the following err from Vapi:

"body": "{\"message\":\"Couldn't Find Azure Voice. Please ensure you're using a valid Azure voiceId. It should look like: \\\"en-US-EmmaNeural\\\"\",\"error\":\"Bad Request\",\"statusCode\":400}

Hey, really sorry for your experience. If possible, could you record a loom video describing this error/behavior or inconsistency in the dashboard with the steps to reproduce it? That way, I can share this with my team, and we'll take a look. We'll even try to reproduce the same so we can fix it for you. Also, I'll request you to share your assistant ID.
