How Voice AI is Transforming Restaurant Phone Ordering

Picture this: It's dinner rush at your restaurant, and your phone is ringing nonstop with takeout and delivery orders. Your staff is juggling in-person customers, food preparation, and trying to answer the phone, but calls are going to voicemail because everyone's hands are full. Meanwhile, hungry customers are calling your competitors instead.

Now imagine this: Your AI voice agent answers every phone call instantly, takes detailed orders, processes payments, and schedules pickup times, while your human staff focuses on what they do best: preparing quality food and serving in-person customers.

This isn't science fiction. It's happening right now.

Phone ordering represents a significant portion of restaurant revenue, but it's also become a major operational challenge. Staff shortages, peak-hour chaos, and missed calls are costing restaurants substantial revenue and frustrating customers.

The solution? Voice AI that works alongside your human team, handling phone orders while your staff focuses on food preparation and in-person customer service, capturing every call and maximizing revenue opportunities.

The Phone Ordering Challenge Facing Restaurants

The Reality of Restaurant Phone Operations

Market Reality:

  • Phone orders represent 20-40% of restaurant revenue for many establishments

  • Average phone wait time during peak hours: 3-5 minutes or more.

  • 30-50% of calls go unanswered during busy periods

  • Restaurant industry turnover rate: 75% annually (National Restaurant Association)

The Operational Impact:

  • Customers hang up and call competitors when phones aren't answered

  • Staff juggling phone orders with in-person service creates bottlenecks

  • Labor costs represent a significant portion of restaurant expenses

  • Missed calls during peak hours result in lost revenue opportunities

Current AI Adoption in Restaurant Ordering:

  • Beef 'O' Brady's launched SoundHound's automated phone ordering at 50 locations (Restaurant Dive)

  • White Castle uses voice AI for both phone and drive-thru orders (SoundHound Q3 2024 Earnings)

  • Various restaurant chains are testing AI for phone ordering and customer service

  • AI adoption in hospitality continues to grow in 2025 (GlobalEDGE)

Early Adoption Results

Beef 'O' Brady's Phone Ordering: In 2024, Beef 'O' Brady's launched SoundHound's automated phone ordering system across 50 locations, enabling customers to place orders through voice AI technology (Restaurant Dive).

Multi-Channel Applications: Voice AI technology can be applied across different restaurant ordering channels. While phone ordering is the primary application, some restaurants, such as White Castle, also utilize similar technology for drive-thru operations, demonstrating the versatility of voice AI across multiple customer touchpoints.

How Restaurant Phone Ordering Actually Works

The Current Phone Ordering Process

Understanding how restaurants currently handle phone orders helps explain where AI can make the biggest impact:

Traditional Phone Ordering Setup:

  • Standard business phone systems connected to restaurant POS

  • Staff multitasking between in-person customers and phone orders

  • Manual order entry into POS systems during calls

  • Payment processing over the phone or at pickup

  • Order coordination with the kitchen and pickup timing

The Current Phone Order Flow:

  1. Customer calls the restaurant during business hours

  2. Staff member answers while managing other tasks

  3. Order details are taken manually and entered into the POS

  4. Payment processed and pickup time arranged

  5. Customer arrives for pickup or delivery is coordinated

The Problem: Staff juggling phone orders with in-person service creates bottlenecks, and missed calls during peak hours result in lost revenue. Restaurants are limited by the number of staff members who can answer phones simultaneously, typically just 1-2 people handling all incoming calls.
