Summary

*Voice is already changing how customers interact with brands. People who moved from storefronts to websites to apps now expect to simply talk to the companies they buy from, and the same shift is reaching suppliers, drivers, and field teams.

*Most enterprise AI so far has faced inward. The larger opportunity is in the conversations companies have with customers and partners every day, and each of those conversations can now be captured, understood, and acted on in real time.

*Any team can build a voice agent that talks back, but value is created only when the agent has context on who is calling. From there, it can adapt to that person, stay within set rules, and get better with every call.

*On Databricks, the agent's brain sits next to your governed data. Context and ontology ground every answer, fast AI decisions tailor each turn, and every call feeds a learning loop.

*Getting started is straightforward. Pick one high-volume routine call, measure how well the agent handles it, and use the DIVA blueprint as the starting point for the next one.

Before you read further: watch this short demo . In this short demo, the voice agent makes a decision in a fraction of a second, partway through the call, and changes how it responds without interrupting the conversation. That same real-time decision making lets a voice agent switch languages, hand a caller to a person at the right moment, or give your most valuable customers the experience they expect. Why voice, and why now Consider three moments that happen every day in consumer businesses: At 6 a.m., a driver running late for a delivery window calls dispatch to move his dock appointment. He’s behind the wheel, so an app isn’t an option. Three other drivers are already on hold, and every minute he waits puts the next delivery at risk. At noon, a drive-thru has four cars in line and one employee on the headset, who is also taking payment and handing out orders. Guests can only order by speaking, so the line moves only as fast as one employee can facilitate orders. In the evening, a storm grounds flights, and stranded travelers call their hotel to hold rooms and push back arrivals. Standing at a gate with a bag in each hand, a phone call is easier and faster than a website. The reservations team has two people and forty calls coming in.

In each of these moments, voice is the fastest or only way the customer can reach the business. So if voice ultimately serves the customer and business need most effectively, why is it so often not available or, in more recent times, executed poorly? For years, the answer was that voice was too hard to get right. That is no longer true. Synthetic voices now sound natural, a conversation can be turned into text and acted on while the caller is still on the line, and today's voice agents can keep pace with the roughly  200 milliseconds it typically takes people to answer each other in conversation. What has not caught up is how most companies think about it. Enterprise AI investment has largely faced inward, toward assistants for employees, while the larger opportunity sits in the conversations companies have with customers and partners every day. One of the largest quick-service restaurant brands in the United States is already building toward exactly that, with a voice agent that lets guests add items to their cart, change their order, and check out simply by talking. Example use cases where voice agents can create value. Every one of these calls, from the driver moving a dock appointment to the traveler holding a room after a storm, depends on more than understanding speech. To be useful, the agent needs the same context your best employee would have: who is calling, what is already in motion for them, and what it is allowed to do about it. The missing piece is knowing your customer Most voice agent pilots prove that an agent can hold a conversation. Far fewer prove that it can be trusted with a real customer. Context closes that gap. With it, the agent can adapt to each caller, stay within your rules about what it can see and say, and get better with every call. Without it, even the most natural voice can only give generic answers. Consider a single call. A loyal customer phones about a late order. The agent already knows who they are, what they ordered, and where the package is. It apologizes, offers a loyalty credit it is authorized to give, and arranges a replacement. If the customer is still frustrated, the agent picks up on it in the moment and decides, in a fraction of a second, to route the call to the next available person. That person picks up with the full context, so the customer neither waits in a queue nor repeats themselves. The same pattern holds when a patient moves an appointment or a subscriber cannot log in after a charge they don't recognize. In each case, the agent picks up when the customer steps away from the app or website and needs an answer now, then hands them back to that same journey when the call is done. Pulling that context together on a live call is the real challenge. It lives across many systems, the agent needs it in a fraction of a second, and it has to stay governed the whole time. That is where Databricks comes in. The brain behind the voice agent: context, ontology, and governance on Databricks A voice agent has two parts. The first is the  conversation layer , which handles the call itself: carrying the audio, turning speech into text, and speaking the reply. Specialist partners do this well. In our prototype,  LiveKit carries the call,  Deepgram handles speech-to-text and the default voice, and  ElevenLabs adds expressive voices. Phone carriers such as  Twilio can bring in regular phone lines. The second part is  the brain , which Databricks provides. On every turn of the call, it looks up the caller’s context, applies your business rules, and chooses the next step, whether that means answering a question, making an offer, or handing the call to a person. It also records each decision so your teams can review it later. The conversation layer shapes how the agent sounds. The brain decides whether it gets the answer right. The brain stands on a foundation of three things that already live together on Databricks. Context is the data the agent needs at the moment: the customer, order, product, and policy data that belongs to the...
