How Hotels Can Use Voice AI and What to Check First

I was reading the documentation for ElevenLabs (a voice AI platform, affiliate link) and its phone agents, trying to work out what a hotel would actually need from one. One detail stopped me. The agent can look things up and take actions in other systems, and that ability matters more for your hotel than how natural the voice sounds.

Most articles about voice AI in hotels talk about the voice. They say the AI sounds human, answers 24 hours a day, and speaks many languages. All of that is true, but none of it helps if the agent quotes the wrong rate.

A voice that sounds friendly is worth very little if it cannot see your real availability.

This post covers the jobs at your hotel where voice AI makes sense, what each job needs from your systems, and what to check before you spend money. It is written so you can follow every step without a technical background, and use it to decide where to start.

A few terms come up throughout this piece, so in plain terms:

The voice is the easy part

Voice platforms like ElevenLabs give you the voice and the phone connection. According to ElevenLabs, its agents work with Twilio and other phone systems, can use a knowledge base of documents you upload, and can call other software to look something up or do something.

That last part is where a voice job at your hotel succeeds or fails. When a caller asks “do you have a room for Saturday?”, the agent needs your live availability and your current rate. If it only has a document you uploaded last month, it will guess or give an old price.

So each use case below has two questions: what does the voice say, and where does the agent get the facts? The first question is easy. The second one is the real project, and it is the same kind of work as connecting your website to your PMS and booking engine.

Answering calls when nobody can

This is the use case everyone talks about first, and it is a good one. Picture a 30-room lodge where the front desk closes at 9 pm. Guests planning a trip often call in the evening, after work, and they reach voicemail.

Now use some simple assumptions, not real data. Say four calls a week come in after hours from people who would book. Half of them book if someone answers, and each booking is two nights at $180. That is about $720 a week, or roughly $37,000 a year. Your numbers will be different, so count your own missed calls from your phone log before you decide anything.

A phone agent can answer those calls, give the real rate and availability, and take the details for a booking. It can also answer the repeat questions, such as check-in time, parking, and pet rules, so your team stops answering the same five questions all day.

The agent should also know when to stop. Complaints, medical issues, and unusual requests should go to a person, or at least to a callback request your team sees first thing in the morning.

Guests who speak another language

If you get guests from abroad, a voice agent can answer in more than one language. ElevenLabs lists many languages for its agents, and the same voice can switch between them.

The list changes over time and it differs between products. So check that the languages your guests actually speak are supported, and test each one with a real native speaker before you trust it. A voice that sounds fine to you can still say a policy in a confusing way.

This is also useful outside phone calls. You can create the same welcome message in three languages in a few minutes, instead of paying for three separate recording sessions.

Audio before the guest arrives

If you send a pre-arrival email with directions, check-in steps, and door codes, some guests will skim it or never open it. A short audio version can be easier for them, especially for a guest driving to a rural property who wants to hear the directions once more.

A few examples of audio you can make with text to speech:

• A 60-second welcome from the owner, played on a link in the confirmation message.
• Spoken directions for the last few miles, including the turn that everyone misses.
• A room guide that explains the heating, the coffee machine, and the Wi-Fi.
• Local tips in the voice of your team, such as where to eat and what to skip.

None of this needs a connection to your PMS, so it is the easiest place to begin. It also shows you how the tool sounds before you trust it with your phone line.

Voiceovers for your website and video

You probably already have good photos of your property. A short video with a clear, warm voiceover adds what photos cannot, which is a sense of how it feels to stay with you.

Text to speech lets you add narration without booking a studio, and you can fix a line by retyping it instead of recording again. It also makes it simple to keep your video up to date when a rate, an amenity, or a season changes.

Keep the voice honest. A voiceover should describe what a guest will really find at your property. If the audio makes your hotel sound grander than it is, the review that follows will say so.

Small jobs behind the desk

Some of the best uses are the ones your guests never notice:

• Hold and menu messages. Replace an old, badly recorded phone greeting with a clear one, and update it when your hours change.
• Staff training audio. Turn your check-in steps, safety rules, or house standards into audio that new team members can listen to on their way to work.
• Audio versions of your content. A guest who cannot easily read a screen, or who prefers to listen, can hear your policies and local guide instead.

Each of these saves you a little time, and none of them puts a guest interaction at risk. They are a low-risk way to learn the tool.

What to check before you start

Before you pay for anything, work through this list. The first four matter most for a phone agent.

1. Does it read live data? Ask whether the agent can look up your real rates and availability from your booking system, and who will build and maintain that connection.
2. Can it hand over to a person? Ask what happens when a caller asks for a human, and check that this works with your phone setup. I could not confirm a clear answer to this on the platform pages I read, so ask before you rely on it.
3. Does it tell the caller it is an AI? Start each call by saying so. It is fair to guests, and it avoids trouble later.
4. What happens to the recordings? Ask where call recordings and transcripts are stored, and check the rules about recording calls where you operate, since they differ by state.
5. Does the license allow commercial use? Some plans do not include it. Read the plan terms on the ElevenLabs pricing page (affiliate link) before you put audio on your website or in an ad.
6. Do you have consent for any cloned voice? ElevenLabs states that cloning another person’s voice requires their explicit consent. Use your own voice, or get written permission from your team member.
7. What does it really cost? Prices and plans change often, so check the current page and add up the cost for the number of minutes you expect, not just the starting price.

A note on the law, since it comes up. In February 2024 the FCC ruled that AI-generated voices count as an “artificial voice” under the Telephone Consumer Protection Act, which means an outbound call that uses one needs the called person’s prior consent. That ruling is about calls you make to guests, such as marketing calls or automated reminders. It does not settle every question about calls you receive. I am not a lawyer, so if you plan outbound calls, talk to one first.

Where to start

You do not need to do everything at once. A sensible order is to begin with the audio jobs that need no connection, such as a welcome message and a phone greeting. Then, if your missed calls are real, try a phone agent that answers only after hours and passes everything unusual to your team.

Do the connection work before you turn on anything that quotes a price. If you want a second opinion on how your website, booking engine, and PMS would talk to a voice agent, you can talk it through with me. And if you are still deciding how AI fits into your booking flow overall, my earlier piece on ChatGPT hotel integrations covers the other side of it.

Start with the job where a mistake costs the least, and move to the riskier jobs only after the first one works.
