How Retailers and Restaurants Use AI for Smarter Operations and Higher ROI

AI for Retail and Hospitality

Walk into a store, grab what you need, and leave — no checkout, no lines. Order room service without picking up the phone. Get menu suggestions that actually match your taste.

This is how AI is already working behind the scenes in retail and hospitality.

From faster service and leaner operations to smarter customer insight, companies like Amazon, Marriott, and McDonald’s are using AI to solve real problems. In this article, we look at what’s working, the tech behind it, and what we’ve learned from our own projects along the way.

What AI Is Doing in Retail and Hospitality

What Businesses Are Gaining — And What’s Getting In The Way

Chatbots & Speech Recognition: Customer Service & Guest Interaction

AI chatbots now handle routine requests like booking confirmations and late check-outs in seconds. Marriott’s chatbot assistant fields thousands of guest questions daily, freeing staff for more complex tasks. In-room voice assistants let guests adjust lighting or order food without picking up the phone.

Hotels using these tools report faster response times — down from 38 hours to under 5 minutes. And 58% of guests say AI improved their stay, citing quicker support and easier communication.

From pre-arrival to check-out, AI is helping businesses respond faster and reduce pressure on staff.

Personalization & Dynamic Engagement

AI systems now analyze purchase history, browsing patterns, loyalty data, and location to deliver real-time, relevant product recommendations. It’s not just a convenience — it drives results: personalized suggestions account for 31% of e-commerce revenue and lead to higher conversion rates and order sizes.

Starbucks uses its app to suggest drinks based on weather, time of day, and past orders. McDonald’s, through Dynamic Yield, updates its digital menus in real time based on location, traffic, and trending items — boosting upsells without feeling forced.

For customers, the experience feels more tailored. For businesses, it means more revenue from the same interaction.

Smart Operations & Revenue Optimization

AI is improving labor planning, demand forecasting, and inventory timing — helping businesses operate more efficiently without compromising service.

Walmart offers two strong examples. An AI chatbot automates supplier negotiations, cutting costs by 1.5%. Its Route Optimization system reduced 30 million miles of travel and 94 million pounds of CO₂, earning the 2023 Franz Edelman Award. That tool is now offered as a SaaS product through Walmart Commerce Technologies — turning internal efficiency into a marketable solution.

Automation & Smart Monitoring

To meet rising expectations for speed and convenience, Lumen Technologies provides the infrastructure that enables real-time automation across retail and hospitality.

With edge computing and high-speed fiber, Lumen supports AI-powered applications like computer vision, dynamic pricing, and smart inventory. Retailers use this infrastructure to run shelf monitoring, foot traffic analysis, and layout optimization directly on-site — without relying on the cloud.

The result: faster service, leaner operations, and more responsive customer experiences, powered by low-latency, high-throughput systems built for AI at scale.

SciForce Case Studies

The big players get the headlines, but real-world AI success depends on adaptability, not scale. At SciForce, we’ve helped retail and hospitality clients tackle problems that don’t make press releases — noisy drive-thrus, last-minute menu changes, inconsistent guest requests, and staff shortages.

Below are examples of how we’ve used custom speech and language models to address challenges that off-the-shelf AI can’t handle.

Building a Reliable ASR System for Drive-Thru Chains

Reliable ASR System

A fast-growing AI company developed a voice assistant to automate the order process at Drive-Thru restaurants, replacing the need for human staff at the speaker. The system uses real-time speech recognition to transcribe natural, informal speech — even in noisy outdoor conditions — and sends structured orders directly to the kitchen system.

Key Challenges

• Noisy environments: Background sounds like engines, traffic, and weather interfered with clear audio capture.
• Informal speech: Customers used slang, paused mid-sentence, or changed their order on the fly.
• Multiple speakers: Overlapping voices and language switching (English ↔ Spanish) required adaptive processing.
• Fast-food-specific vocabulary: Menu terms and brand phrases needed custom model training.
• Low-latency requirement: Orders had to be transcribed and processed in under 400ms to maintain conversational flow.

AI-Powered Solution

• Voice Activity Detection filters ambient noise and identifies customer intent without wake words.
• Custom ASR models trained on real Drive-Thru audio accurately transcribe informal, multi-turn orders.
• Real-time clarification prompts kick in when confidence is low, improving accuracy without restarting the order.
• Multi-language support enables seamless switching between English and Spanish.
• Staff voice commands update inventory in real time (e.g., “out of fries”), ensuring order accuracy.

Impact

• Order time reduced by 18–25%, speeding up peak-hour operations
• Labor costs lowered by up to 15% through automation at the ordering stage
• Average order value increased by 12% thanks to AI-powered upselling prompts

This solution shows how speech recognition and conversational AI can replace manual order-taking in high-noise, high-speed environments — enhancing speed, accuracy, and customer satisfaction without disrupting kitchen workflows.

NLP Engine for Structured Ordering in Drive-Thru Systems

NLP Engine for Structured Ordering

A leading Drive-Thru AI provider implemented a domain-specific natural language processing (NLP) system to convert unstructured, informal customer language into structured food orders. Built to support complex fast-food menus, the system handles combos, modifiers, promotional items, and multilingual input in real time.

Key Challenges

• Unstructured customer language: Orders like “double burger with extra cheese, no pickles” required interpretation despite slang, pauses, or revisions.
• Branded phrasing & synonyms: Phrases like “Mega Cheddar” or “the big meal with fries” had to map correctly to structured POS items.
• Combo logic & pricing: The system needed to identify incomplete or misstructured orders and reformat them automatically based on menu rules.
• Frequent menu changes: Promotions and limited-time items had to be added quickly without retraining the entire model.
• Context across dialogue turns: Customers often revised or added items mid-order, requiring persistent order memory.

NLP-Driven Solution

• Custom NLP engine parses free-form language into structured order representations (e.g., JSON format), supporting modifiers, dependencies, and bundled pricing.
• Menu structuring layer formalizes combo logic, required/optional components, and upsell conditions for accurate parsing and pricing.
• Synonym & brand name mapping connects informal or creative phrasing to official item IDs in the menu database.
• Multi-turn context tracking enables mid-order changes without loss of prior inputs — ensuring accurate, coherent final orders.
• Multilingual understanding auto-detects and processes English or Spanish input, including mixed-language phrasing.
• Upselling logic integration suggests combos or add-ons in real time based on intent and incomplete selections.

Impact

• 85–88% order structuring accuracy from informal language input
• 90%+ success recognizing variant phrasing and brand terms
• Real-time restructuring of fragmented or out-of-order combos for pricing compliance
• Same-day updates for new menu items or promotions
• 10–12% uplift in average order value via NLP-guided upselling

This solution highlights the strength of NLP in converting messy, casual language into precise, structured data — powering fast, intelligent, and adaptable food ordering workflows at scale.

Conclusion

Retail and hospitality businesses are using AI to reduce wait times, manage inventory more accurately, and handle routine customer requests with less manual input. Applications include demand forecasting, restock planning, and automated service responses — leading to fewer delays and more relevant interactions.

The most consistent results come from applying AI to specific, well-scoped problems. Success depends on data quality, system compatibility, and how customer information is used.

If you’re considering AI for a concrete operational need, we can help you design and implement the right solution.
