What does it take to make a voice AI agent reliable?

Reliable voice AI comes from rigorous testing and evals, and Rohan Vasishth from Bluejay sees trust as the fundamental bottleneck holding back enterprise deployment. Rohan is Co-founder and CEO of Bluejay, which tests and monitors voice and chat AI agents for companies including Google and DoorDash. We work through what to test, when to test it and what each approach costs. We discuss why testing voice AI introduces a whole new layer of complexity, from accents and background noise to interruptions and speech recognition errors. Rohan also shares how customers can stress-test agents, why starting with text-based evaluations can save time and money, and how businesses can identify and reduce the latency customers actually experience. Rohan closes by exploring the widening gap between rapidly advancing AI capabilities and slower enterprise deployment, and why evaluation is essential to building the trust needed to close it.

Keeping control of your AI agents

Stacey Kyler and Guy Tonye of Zammo return to the show for the first time since 2021. Back then they were building for Google Assistant, Alexa and Cortana. ChatGPT arrived soon after and reshaped what customers expected. They cover the move from NLU and diagram flows to agentic systems, why customers now want both the freedom of Gen AI and firm control, how Zammo enforces determinism at the code level while Gen AI handles the conversation, and why evals are the thing Guy would add to any conversation design course today.

The two things contact centres have been missing until now

The contact centre holds a record of almost every customer interaction. Every conversation carries a signal about why customers are calling and what is behind it. Processing those conversations at scale took the power the contact centre never had before. Ping Wu, CEO of Cresta, joins us to work through what that shift means for enterprise contact centres, from cutting the calls that should never happen to automating the ones that can be. We get into how AI changed what a contact centre can see. Every call, every screen, every exchange can now be processed rather than sampled. Human effort never scaled the way silicon does, so for years most of that record went unread. Large language models bring processing power and language understanding to work through millions of conversations, see what is driving them and turn that into insight, coaching and automation.

From chatbot to voice AI: what changes?

Voice AI is the channel everyone is talking about in 2026. One of the biggest things slowing it down is often already sitting inside your stack. In this episode, I’m joined by Endre Davids from Seamly to explore what really happens when businesses take an existing chatbot and move it into the voice channel. We discuss why latency often starts deeper in the conversational platform than teams expect. Endre explains how companies can spend time optimising speech recognition and text-to-speech while the chatbot itself is responsible for much bigger delays. The conversation gets into why voice needs a different interaction model, because people speak differently from how they type. That puts far more pressure on getting the conversation design right. We also cover how to manage perceived latency, when it makes sense to reuse existing chatbot infrastructure and how sentiment, multimodality and customer context could shape richer voice experiences. Endre and I keep landing on the same point. The success of voice AI depends heavily on conversation design, and voice punishes the shortcuts that chat lets you get away with.

Cobus Greyling: why intents, graphs and conversation design have come full circle

I'm joined by Cobus Greyling, AI evangelist at Kore.ai, for a wide-ranging conversation on where enterprise AI actually stands today. We explore why many of the ideas now being presented as breakthroughs, from graph engineering and orchestration to intent detection and state management, have deep roots in conversational AI. We also get into one of the biggest barriers to enterprise AI adoption: data. We highlight why customer experience could become the entry point for much wider organisational transformation. We touch on how forward-deployed engineers could help businesses navigate that change and why security will become increasingly important as AI agents gain access to more systems and information. I close with a buzzword bingo round for Cobus covering fleet engineering, agent swarms, orchestration and universal agents, and Cobus explains why he thinks Open Claw was the biggest red herring of the year.

From answers to actions: building better government AI

Plenty of AI assistants can answer the question in front of them. Fewer can work out what someone is actually trying to do and help them do it. In this episode, we're joined by Pete Kowalczyk, AI Conversation Designer at the Government Digital Service (GDS), to talk about designing AI experiences across the vast and complex landscape of UK government services. Pete explains how GDS is exploring knowledge graphs, persistent state and goal detection to move beyond basic RAG systems. The aim is to connect information with action and guide people through non-linear journeys, such as moving house or registering a birth. One of the key goals is to reduce the burden created by fragmented processes and legacy systems. We discuss why conversational systems need to track user goals, how small interaction loops can be built into rich experiences over time and why transitions between stages of a conversation carry so much weight for trust and usability. We also get into progressive disclosure, deciding when an AI should stay concise and when it should offer more, and how to judge whether a link belongs in a response at all. Pete points to a bank surfacing patterns in someone's spending as an example of how organisations can build proactive features from data they already hold, rather than only responding when asked. Pete shares how the designer role is evolving. Designers now need sufficient technical understanding to prototype and work directly with LLMs through practices like vibe coding, while maintaining the creative ability to understand experiences beyond incremental chatbot improvements. He closes with a warning against the industry's current resolution rut, where success gets defined too narrowly as fast ticket resolution rather than genuinely useful, proactive AI.

How Simplyhealth scaled voice AI to resolve 30% of calls with Paul Atkins

Almost a third of Simplyhealth's incoming calls are now resolved by AI, and email handling time has fallen from 12 minutes to 2. The company is achieving those gains while maintaining the service standards that placed it 31st in KPMG UK's Customer Experience Excellence report. In this episode, we're joined by Paul Atkins, Head of Business Optimisation at Simplyhealth, the UK's member-owned health cash plan provider serving around 2.5 million customers. Paul explains how Simplyhealth introduced voice AI gradually, tested more than 1,000 real customer calls and built trust across a highly regulated organisation. We also get into how Simplyhealth measures resolution, quality and customer effort, why intensive human listening still matters during rollout, and the organisational call to define what "good enough" looks like rather than letting advisors over-engineer every reply. Paul talks through the role of business readiness teams in driving adoption and why knowledge management could become the next major challenge in making AI work at scale.

Inside the platform enterprises use to build AI agents with Rasmus Hauch, CTO at boost.ai

Safe, reliable, production-ready AI agents don't come from the model. They come from everything built around it. Rasmus Hauch is CTO of Boost.ai, one of the enterprise platforms banks, insurers and public sector organisations use to build customer-facing AI agents. His work sits one layer below every deployment: the orchestration, the guardrails, the testing infrastructure and the model choices that decide whether an agent holds up in front of millions of customers. In this episode, Rasmus opens that layer, explaining why conversational AI is shifting away from traditional conversation flows towards orchestration, testing and continuous evaluation. He walks through how Boost approaches it in practice: persona-based simulation across thousands of digital and voice conversations, predefined test suites for jailbreaking attempts and financial advice, layered guardrails inside and outside the agent, and a trust loop that feeds production results back into the build. Rasmus is direct about the hard parts. We touch on why the big LLM providers can't yet deliver the consistent response times voice demands, which is why Boost runs fine-tuned smaller models on its own infrastructure for latency-critical voice work. Rasmus explains why he advises clients against plugging in their own models. We also discuss where liability sits under the EU AI Act when an agent gets it wrong, and why a volcano eruption in Iceland is a good example of what no model can be trained for. Towards the end, Rasmus shares what's exciting him right now, including adaptive voice, real-time language switching and where agent-to-agent protocols are heading.

How ING is building the instant mortgage with agentic AI

A traditional mortgage can take weeks to process. Every application moves through rounds of document requests, condition checks, and broker queries before a decision is made. ING is using agentic AI to change that. In this episode, Bahadir Yilmaz, Chief Analytics Officer at ING, explains how one of Europe's largest mortgage lenders has implemented agentic AI in its mortgage process. The system is live in the Netherlands, rolling out to Germany. Applications now complete in days, a full day faster since AI was introduced. The goal: the instant mortgage, within the next couple of years. We cover why ING chose its highest-stakes product for its first agentic deployment, why the agent handles operational work while underwriting remains with traditional machine learning, and how the team built a golden dataset of 400 mortgage applications to test a system no one had tested before. Furthermore, Bahadir shares how ING scaled to 114 AI initiatives with 42,000 employees using AI. We discuss why risk management came before ambition, and why only 10 of his 600 experts were ready to build agentic systems.
