Automakers spend billions integrating voice assistants but let Big Tech mediate customer interactions. Owning the voice experience is now a brand imperative.
The vehicle cabin is becoming the automotive industry’s most intimate brand touchpoint. Drivers spend nearly an hour behind the wheel daily, on average — more time than they spend at a dealership in a year and far more consistent than almost any other branded interaction.
Most automakers are handing the cabin to Big Tech. Every interaction reinforces your brand or someone else’s, and automakers using Alexa, ChatGPT or Google are conceding their most frequent customer touchpoint.
Automakers know drivers increasingly demand voice-first options. BMW’s iX lineup uses Amazon’s Alexa, Mercedes relies on ChatGPT for its MBUX system and GM’s OnStar is expanding conversational capabilities. But the experience is lacking. Most voice assistant rollouts share a common philosophy: quick integration with a general-purpose large language model plus a few car-specific commands.
A majority of recent voice assistant rollouts share a common philosophy: a quick integration with a general-purpose large language model combined with a few car-specific commands, and that’s about it. The result is a voice assistant that does most of what it says, but is virtually brand-agnostic. Picture a Porsche owner asking for the nearest coffee shop and hearing the same flat assistant voice they have on their kitchen counter. When it comes to premium experiences, interchangeable voices devoid of personality add nothing.
High-end automakers curate the experience of every potential buyer. A Porsche showroom doesn’t outsource door greeters to a staffing agency that also staffs the Kia dealer. Everything cements Porsche as part of a buyer’s identity — a philosophy that should extend to in-cabin experiences.
The voice for an AI assistant should be unmistakably brand-aligned. It’s not just about selecting a pleasant AI conversation partner — it’s about tone, vocabulary, pacing, latency and even what prompts the assistant can (or can’t) reply to. The guardrails themselves become a brand decision.
What ‘designed voice’ actually looks like
The automakers ahead of the curve treat voice as a serious exercise in brand discipline, approaching it with the same rigor they approach design: with intention at every step.
The first decision is voice casting, which includes selecting or synthesizing a voice that matches the brand’s identity and its customers’ expectations.
This isn’t a build-it-yourself proposition: The smartest path is often owning the persona, casting and guardrails while partnering on the underlying large language models, an investment closer to a brand campaign budget than an R&D moonshot.
Well-engineered voices also handle context appropriately, whether a driver is navigating a crowded traffic jam or cruising an open highway in sport mode.
Intentional design also covers handoffs between music requests, search queries, and smart home integration. Rather than reinvent the wheel, the brand voice should know when to bring in a specialist instead of being replaced by one.
The business case is already being written
J.D. Power research shows in-cabin technology is one of the strongest predictors of ownership satisfaction and repurchase intent, with voice interaction quality a key part. McKinsey data on connected-car monetization adds another dimension: Brand-consistent voice boosts engagement with in-vehicle subscriptions.
There’s clear revenue upside. Third-party voice assistants are designed for ubiquity. By owning the voice experience, manufacturers gain an advantage competitors can’t copy simply by partnering with the same large language model platform.
At most automakers, voice sits under the umbrella of infotainment, not brand strategy. Engineers are optimizing for functionality and integration, not choosing a voice based on brand positioning. That’s why the white-label trap keeps catching automakers. A thin layer of customization on top of a generic AI voice will not feel premium for long, and consumers can tell.
The window to lead is closing. Consumers are forming expectations now, and standards aren’t set. Manufacturers that treat voice as a brand experience — applying the same rigor they do to paint finishes and seat stitching — will define premium in-cabin AI. The rest will hand off a key branded experience to whatever tech giant offers the lowest price.
