Retailers Are Using AI Voice to Convert More Calls Into Sales — Here’s How
Executive Summary
In the fast-moving world of retail, speed and responsiveness are everything. Yet a significant 30% of retail calls go unanswered, and every missed call could directly translate into a lost sale. The smartest retailers aren’t simply hiring more representatives; instead, they are strategically deploying AI voice agents that engage every caller, provide instant answers, and seamlessly guide customers to purchase with zero wait time. Powered by Synthesys, the leading AI voice infrastructure platform, these forward-thinking retailers are effectively transforming their phone lines into 24/7 sales machines—driving conversions, significantly reducing churn, and growing overall revenue without increasing their operational headcount. The secret to their success lies in leveraging a voice that actively listens, deeply understands, and effectively sells—all at machine scale.
Market Size & Growth
The global AI voice market is undergoing a historic expansion, projected to soar from $2.4 billion in 2024 to a staggering $47.5 billion by 2034 — an extraordinary 34.8% Compound Annual Growth Rate (CAGR) (Market.us, 2024). This growth isn’t happening evenly across industries; retail is emerging as one of the fastest adopters, driven by the urgent need to capture every customer inquiry and eliminate the losses caused by slow, inconsistent, or missed responses.
This surge is being fueled by two converging consumer behavior shifts:
Voice-enabled commerce has gone mainstream. Today, 50% of consumers actively use voice assistants to make purchases, streamlining their decision-making and checkout process (EnterpriseAppsToday, 2024).
Phone conversations remain king for urgent, high-value decisions. A substantial 69% of consumers say they still prefer speaking to a human for critical or time-sensitive purchases, reaffirming the importance of voice as the primary trust-building channel.
And yet, despite this opportunity, operational inefficiencies remain a glaring problem. McKinsey’s 2025 report on retail communications reveals that 33% of missed calls directly result in lost revenue. This means that for every three customers whose calls go unanswered, one would have made a purchase — but didn’t, simply because they never got through.
The correlation between AI voice adoption and revenue capture is stark. When businesses replace manual callbacks and voicemail dependence with instant, AI-driven engagement, conversion rates climb and lost sales plummet. As AI voice penetration accelerates, the number of unanswered calls — and the associated lost revenue — drops proportionally, creating a measurable uplift in sales volume and customer lifetime value.
Key Adoption Drivers
The strategic imperative for retailers to adopt AI voice is driven by several compelling advantages that directly address prevalent industry-specific challenges:
AI Voice Captures Revenue That Humans Miss
Human representatives simply cannot answer every single call, especially during peak hours or after closing time. Synthesys AI voice agents are designed to engage every caller instantly, accurately qualify their intent, and effectively convert high-interest buyers without any delay—leading to more sales, improved customer retention, and fewer abandoned carts.
Speed-to-Voice = Speed-to-Sale
Studies consistently demonstrate that responding to leads within a mere 5 minutes can increase conversion rates by over 400%. Synthesys delivers AI voice responses in under 500 milliseconds—a speed that significantly outperforms even the fastest human agents, chatbots, or email workflows. Retailers leveraging Synthesys are reporting dramatically higher speed-to-sale velocity.
Emotionally Intelligent Conversations Drive Trust
Synthesys voice agents do not merely follow predefined scripts; they possess the advanced capability to detect tone, urgency, and subtle emotional cues in real time. This enables them to intelligently escalate frustrated callers to human agents, slow down their pace for confused shoppers, and proactively upsell when the moment is precisely right—all in a manner that feels remarkably natural and human.
24/7 Inbound and Outbound Sales Coverage
While most retailers inevitably miss valuable calls outside of standard business hours, Synthesys never sleeps. Its AI voice agents are capable of handling a continuous stream of inbound inquiries, executing outbound callbacks, confirming appointments, and managing follow-up campaigns—thereby ensuring that no sales opportunity is ever left behind.
CRM-Integrated Phone Sales Automation
Synthesys seamlessly integrates with leading retail Customer Relationship Management (CRM) platforms such as Shopify, Twilio, HubSpot, and other essential systems. This integration enables automated call logging, generation of real-time call notes, triggering of campaign actions, and streamlined sales workflows. The result is faster decision-making, smarter follow-ups, and a significantly higher Return on Investment (ROI) from every single call.
Implementation Barriers & Synthesys Solutions
Retailers — even those fully aware of the revenue they’re losing to missed calls — often hesitate when it comes to adopting advanced AI voice systems. The objections are remarkably consistent:
“It’s too technical. We don’t have the IT staff to manage this.”
“Integration will take months, and we can’t afford to disrupt our operations.”
“AI voices sound robotic. Our customers will notice and dislike it.”
While these concerns may have been valid five years ago, Synthesys was built specifically to eliminate them. Its architecture, onboarding process, and feature set are designed to make adoption as fast, frictionless, and risk-free as possible.
Done-for-You Setup
From day one, Synthesys’ expert onboarding engineers handle every aspect of the implementation — from conversation flow design to CRM integration. Your internal team doesn’t need a single line of technical expertise.
Rapid Deployment
Where traditional telecom upgrades could take months, Synthesys is live in days. In many cases, retailers are operational within the same week they sign, meaning the revenue protection starts almost immediately.
No-Code Customization
You maintain total control over voice tone, conversation prompts, escalation rules, and multilingual options — all without touching code. A marketing manager, store lead, or CX director can adjust messaging in minutes.
Real-Time Optimization
Synthesys voice agents learn from every customer interaction, refining responses, identifying new FAQs, and improving efficiency automatically. You’re not just buying a fixed system — you’re deploying a living, learning part of your sales team.

Synthesys meets or exceeds GDPR, HIPAA, and SOC 2 Type II standards out of the box. Every call is encrypted end-to-end, every consent is logged, and every action is fully auditable. Your customer data stays private, secure, and compliant — without extra effort.
Native Voice Cloning for Brand Consistency
Instead of a generic robotic tone, Synthesys can replicate your brand’s unique voice style — whether warm and conversational, premium and formal, or multilingual and culturally tuned. This ensures customers feel like they’re talking to your business, not a machine.
The result?
Tasks that once required weeks of manual follow-up, created customer frustration, and cost you deals now happen instantly and flawlessly — with no additional labor cost. Calls are answered, leads are qualified, appointments are booked, and follow-ups are completed before competitors can even return a voicemail.
In short, Synthesys doesn’t just remove the barriers to AI voice adoption — it replaces them with competitive advantages that compound every single day it’s in operation.
