Beyond the Bot: Why the Future of Customer Service Belongs to Voice AI
By Claudio Rodrigues, Chief Product Officer, Omilia
The contact center industry is at a crossroads: either control the rise of autonomous AI or risk being controlled by it. Voice AI is no longer a futuristic experiment, it’s a live force already shaping how customers experience brands. AI agents have become entrenched in the customer service industry. Market analysts suggest the AI customer service sector could grow from around 13 billion dollars in 2024 to more than 83 billion by 2033 and some reports estimate 95 percent of customer interactions will involve AI by 2026.
Still, rapid adoption does not mean smooth sailing. For every organization that sees measurable gains in efficiency and customer experience, there’s another discovering that an LLM Ex Machina approach - simply throwing a large language model at customer problems - leads to uneven performance, frustrated callers, and shaken trust.
As a Chief Product Officer, I see the challenge less as whether to embrace Voice AI, but how to adopt it with control, discipline, and confidence. Many IT and security leaders who are implementing AI – some surveys point to 67 percent – agree they don’t have the governance, policies and processes in place to manage the associated risks.
Leadership’s mix of enthusiasm and unease defines the moment. Businesses see the potential for automation to reduce costs and improve customer experience, yet I’ve seen firsthand that they remain cautious about losing control of autonomous AI agents or damaging customer trust if they fail. Rather than pulling back completely, I’d urge them to take a more measured, deliberate approach to deployment that can unlock the benefits while managing the risks.
Autonomous voice self-service can deliver significant gains. It lowers operational costs and provides round-the-clock availability without the fatigue or scheduling issues that often plague human teams. Done well, it can ensure companies provide a consistent brand experience, avoiding the unpredictability of service levels that sometimes happens when a live agent is under pressure. And when demand spikes – say, an airline faces weather-related cancellations, or a bank sees a sudden wave of fraud alerts – voice AI can scale much faster than a traditional human resourced contact center.
A clearer process can avoid that trap: first, define the problem, then select and tune the right AI. That’s why we’ve created our own Agentic Adoption Framework. Starting with simple, deterministic bots for high-volume, low-complexity tasks like balancing checks or password resets gives teams measurable data on accuracy and satisfaction. Once those basics are proven, organizations can introduce more autonomous systems, backed by monitoring, sentiment tracking, and clear escalation triggers. Only after performance has been validated and stakeholders are confident should full autonomy roll out more broadly. This gradual path of Agentic AI adoption builds internal trust, provides measurable ROI, and prepares teams for a cultural shift toward more intelligent automation.
Industry-specific training also matters. A passenger trying to rebook a canceled flight, a patient checking lab results, and a banking customer disputing a chargeback each use very specific language based on the task they’re looking to complete. Bots tuned to industry specific tasks understand those nuances better. Sentiment analysis is another key piece. Systems that can detect growing frustration or urgency and pass the conversation to a human – without forcing the customer to start over – can turn a potentially negative moment into one that has a thoughtful resolution and builds loyalty.
Voice AI further depends on technical discipline. Hyper low latency, accurate speech recognition, contextual understanding, and natural-sounding text-to-speech need to work together smoothly. Companies that own or tightly integrate their technology stack are often better positioned to avoid gaps and adapt quickly, giving them the reliability and flexibility to tailor solutions to their specific needs.
Voice AI has reached a level of maturity where end-to-end automation is within reach for many organizations - but the winners won’t be those who chase hype. They’ll be the ones who define customer problems clearly, adopt in phases, and measure relentlessly.
Handled with control, domain expertise, and a customer-first mindset, autonomous voice self-service can do more than trim costs. It can strengthen loyalty, safeguard brand reputation, and build operational resilience at scale. The enterprises that move thoughtfully today won’t just survive the transition to agentic AI, they’ll shape it, and in doing so, redefine what customer service feels like in the next decade.
