Yes, I have, just now, been thinking about how few, and featureless, syllables I can utter to determine if an unknown caller has a legitimate reason for calling, such as a large-delivery driver, medical lab or other real call.
It seems the best tactic is to make the caller do as much of the talking as possible.
Or use a generic cloned voice to interact with unknown callers.
