Voice is moving from a consumer convenience into a serious customer engagement design choice, and CX teams may need to rethink where typing, tapping, and forms still make sense.
Peter Bell, VP of Marketing EMEA at Twilio, told CX Today that the shift is already visible in how people use technology at home and at work. Twilio’s UK research found that 22% of Brits now talk more than they type when interacting with technology, with voice increasingly used for speed, multitasking, and more natural digital experiences.
For Bell, the signal is less about a single channel replacing another and more about customer expectations changing around effort.
“Consumers are jumping at it. And like you say, was 22%. So, you know, close on a quarter of people are now talking to that technology. it, you know, Alexa, be it talking to their laptop. It no longer feels weird because it works and it's natural.”
That change matters for enterprise CX because consumer behavior rarely stays outside the workplace. Employees and customers who use voice naturally in daily life begin to expect the same ease when they need support, information, or action from a brand.
As CX Today recently reported, Twilio has also seen self-service voice usage grow more than 50%, adding to the evidence that voice AI is moving beyond isolated pilots and into production customer engagement environments.
Voice CX Depends on the Moment, Not the Hype
Bell was careful to avoid treating voice as a universal answer. Instead, he argued that the right interface depends on customer context, urgency, privacy, and emotional state.
A customer involved in a car crash, for example, is unlikely to want to complete a form on a phone at the roadside. A traveler stuck in traffic and about to miss a flight may also need a fast spoken interaction, although that situation may be easier for an AI agent to resolve without immediate human intervention.
A mortgage application is different. Customers may prefer a keyboard or form when they need to share salary, marital status, credit information, or other private details in a public space.
Bell said CX teams need to resist the instinct to apply voice everywhere simply because the technology has improved:
“We've got to be smart about this. know, it's the advances in voice technology are amazing and I think can transform a lot of our interactions with technology, but it's not a one-size-fits-all.”
That distinction is important for enterprise teams under pressure to modernize customer engagement. A voice interface can reduce friction in high-stress, time-sensitive moments, but it can add discomfort or risk when the interaction involves sensitive data, complex documentation, or a customer who needs time to think.
Context Is the Difference Between Help and Frustration
The interview repeatedly returned to context as the critical ingredient in successful voice CX. Bell argued that brands already know how frustrating it is when a customer moves from one agent to another and has to repeat security checks, explain the issue again, or restart the conversation.
Voice risks amplifying that frustration if it recreates the same broken handoffs with an automated interface. However, Bell said modern communications infrastructure can carry sentiment, history, and conversation summaries across channels and between AI and human agents.
