Modern AI voices are good. Good enough that some business owners ask me whether they should just let callers assume they're talking to a person. My answer is always the same: no. Tell them.
Because it's becoming the law
In the European Union, the AI Act's transparency rules started applying on 2 August 2026. They require AI systems that interact directly with people, including voice assistants, to be designed so people are told they're dealing with an AI, unless that's already obvious from the situation. Fines can reach €15 million or 3% of worldwide annual turnover.[1]
California has had a narrower rule since 2019, requiring bots that interact with people online to sell goods or services to disclose that they're bots.[2] Other places are heading in the same direction. If you serve customers across borders, it's simpler to disclose everywhere than to keep track of where you must.

I'm not a lawyer, and this isn't legal advice. Check the rules where your customers are. But the direction is clear.
Because trust is the whole point
Customers are already wary. In a Gartner survey, 64% said they'd prefer companies didn't use AI for customer service.[3] If someone works out halfway through a call that the "person" they've been chatting to is an AI, that wariness turns into a feeling of being tricked. That feeling sticks to your brand far longer than the call itself.
Being upfront costs you one sentence. Being found out costs you the customer's trust.
What good disclosure sounds like
It doesn't need to be awkward or robotic. Something like: "Hi, you've reached Coral Haven. I'm the resort's AI assistant. I can help with bookings and questions, or put you through to the team at any time." That one line tells the caller what they're talking to, what it can do, and that a person is available if they want one.
In our experience, most callers don't mind talking to an AI. What they mind is not being told, and not being able to get out. Get those two things right and the rest is about how well the agent actually helps.
