Voice UX Design Agency

What We Deliver
End-to-end voice UX design: from dialogue and persona to misrecognition recovery, multimodal fallbacks, and developer handoff.

Conversation & Dialogue Design

Error & Misrecognition Recovery

Voice Persona & Tone

Multimodal Fallbacks

Prompt & Confirmation Design

Latency & Turn-Taking UX

Accessibility-First Flows

Voice Onboarding

Usability Testing for Voice

Developer Handoff

We design voice experiences that recover gracefully when speech goes wrong, because it will.
How We Do It
Our Process
How We Design Voice UX Design
1

AI Behaviour Audit
Before we open Figma, we map what your AI actually does: its capabilities, failure modes, latency profile, and output variability. UX that ignores model behaviour produces interfaces that lie to users. We design honest experiences.
UI-UX Design
2

User Mental Model Research
We study how your users conceptualise the system: their expectations, anxieties, and trust triggers. Most users overtrust or undertrust AI, and both kill retention. We design to calibrate those mental models, not exploit them.
UI-UX Design
3

Trust-Gradient Architecture
We apply our Trust-Gradient framework to structure the experience: what the system surfaces proactively, what stays on demand, and how it communicates uncertainty without eroding confidence. This is the skeleton the product needs before a pixel is placed.

Interaction & Prompt Design
We design how users direct the system, how it responds, how it handles ambiguity, and how it invites correction. Good interaction design here is invisible; bad interaction design is why users abandon the product mid-task.

Visual & Motion Design
Loading spinners were designed for deterministic software. AI products need a different motion vocabulary: streaming, progressive disclosure, confidence gradients, and graceful degradation. We design this layer with the same rigour as static UI.

6

Prototype, Test & Iterate
We build interactive prototypes with simulated AI outputs, including edge cases, and run moderated usability sessions before your team writes production code. Issues found in prototype cost a fraction of issues found post-launch.

Handoff & Design System
You receive pixel-perfect specs, an AI-specific component library, interaction documentation, and a living design system built to scale as your model evolves.

Why Goldenflitch for Voice UX Design
We are not a generic design studio that added 'AI' to the service list. Our AIXD division was built specifically for AI-native product work, and Trust-Gradient Engineering is the proprietary framework that separates products that retain from products that churn.
AI-Native Thinking
We design from the model outward: understanding behaviour, latency, and uncertainty before touching Figma.
Trust-Gradient Engineering
Our proprietary AIXD framework maps every trust-critical moment in the journey and designs the interface response for each, the difference between week-one adoption and week-three churn.
Intent-Lattice Architecture
We structure what the system surfaces proactively vs on demand, and how uncertainty is communicated without eroding user confidence.
Rapid Prototyping with Simulated AI Outputs
Interactive prototypes, including AI edge cases: validated with real users before your engineers write a line of code.
Cross-Functional Collaboration
We run working sessions with your ML and AI engineers to align on model behaviour and output formats before design is finalised. No retrofitting.
Scalable AI Design Systems
Every component accounts for AI-specific states: loading, uncertain, streaming, correcting, and is built to scale as your model evolves.
Outcome-Driven, Not Aesthetic-Led
We measure success by activation, task completion, and retention. GoalTeller: +41% activation. ERPForce: 2.3x demo requests. Design that earns its place.
Industry-Agnostic Depth
AI product design across fintech, healthtech, SaaS, consumer, and enterprise: wherever the user's primary interaction is with a model-generated output.

Design a Voice Product That Works Without a Screen
Voice removes every visual safety net. Goldenflitch designs the dialogue, recovery, and fallbacks that keep users oriented when there's nothing to look at.

Voice Has No Undo Button. Design Like It.
A voice interface can't show a menu, highlight an error, or let users scan their options. Every affordance has to live in the dialogue itself. Designing for voice means designing for ambiguity, interruption, and the absence of a visual safety net: exactly where most voice products fail.
