SoundHound's agent completes about 90% of orders on its own, in under a minute, around the clock.
White Castle partnered with SoundHound to roll voice AI out to more than 100 of its drive-thrus, with many of those lanes running 24/7. According to the companies, the system completes roughly 90% of orders without human help, processes a typical order in under 60 seconds, and runs end to end as an always-on agent rather than a human-assisted one.
White Castle has been an early mover on restaurant automation in general, and the appeal of voice AI is consistency. The agent greets every car the same way, never forgets the upsell, and is awake at 2am. It originally tested drive-thru AI back in 2020 before moving to a direct deployment, a reminder that even the brands that look fast today started with a careful pilot.
The honest counterpoint belongs here too: not every pilot has gone smoothly. McDonald's tested drive-thru voice AI, found accuracy in the low 80% range against the 95%-plus it wanted, and stepped back before later rebuilding on a new platform. The lesson is not that the technology fails, it is that it has to be trained and tuned for the specific business, which is exactly the part most operators should not try to do alone.
Multi-location rollouts matter because they prove consistency. An agent that behaves the same across a hundred restaurants is one that will behave predictably on your single line, every hour of every day.
Under the hood, a modern AI voice agent is nothing like the old phone tree. It answers in under a second, understands natural, interrupted, real-world speech instead of "press 1 for sales," and holds a genuine back-and-forth, including the corrections and half-sentences people actually use on the phone.
Mid-conversation it pulls context from your calendar and CRM, checks real availability, and books or reschedules on the spot. It captures the caller's name, number, and reason for calling, hands off to a human only when something genuinely needs one, and the instant the call ends it texts you a summary and logs every detail. That is the same machinery behind every deployment on this page, just pointed at a different script.
The dependability that works across a hundred restaurants works just as well on your one number, as long as it is trained on your business. That training is the part we do for you.
If a chain trusts voice AI across a hundred kitchens, a single cleaning company can trust it on one line, answering, quoting a recurring clean, and booking the first visit while the owner is on a job across town.
The difference for a small business is that you build none of it. We do. It starts with a 30-minute intake call where we capture your services, pricing, hours, and the questions your customers ask most. We write the scripts, build and train the agent, connect your calendar and CRM, and test every flow before it touches a live caller. Most agents go live on a dedicated number within five business days, and we keep tuning as your business changes. It plugs into the tools you already use: Google Calendar, Outlook, Calendly, your CRM, and SMS.
Most do not ask. The voice is natural and it answers in under a second. When someone does ask, they rarely mind once the call goes smoothly and they get what they called for. The fastest way to judge it is to call our demo line and hear it yourself.
Usually five business days from your intake call. We build, train, and test it for you, then it goes live on a dedicated number, with no DIY setup on your end.
Google Calendar, Outlook, Calendly, your CRM, and SMS, so it can check availability and book in real time and keep your records current after every call.
The brands above had teams and budgets. You get the same capability, done for you, on your number, in about five days.
