Voice commerce purchasing through voice-activated assistants like Amazon Alexa and Google Assistant—is revolutionizing the e-commerce landscape. By 2025, over 40% of U.S. households own a voice-enabled device, contributing to more than 20% of online purchases (Statista, 2025). For sellers using Amazon’s FBA or Walmart’s WFS, optimizing your business for voice searches is no longer optional—it’s essential.

This comprehensive guide dives deep into what voice commerce is, how it works, actionable beginner-to-advanced strategies, and tools to ensure your products are the top choice when customers shop via voice.

What Is Voice Commerce?

Voice commerce allows customers to shop by speaking commands to voice-activated devices. Customers can effortlessly order products through smart speakers or voice assistants embedded in smartphones, cars, or smart home systems. For instance, consumers might say:

• “Alexa, order laundry detergent.”

• “Hey Google, buy socks from Walmart.”

This seamless, hands-free experience aligns perfectly with the modern consumer’s desire for convenience, and voice-enabled sales are expected to reach $40 billion by 2025 (eMarketer, 2024).

How Voice Commerce Works: The Buyer’s Journey

Voice commerce combines natural language processing (NLP), e-commerce integration, and fulfillment efficiency:

1. User Initiation
The user initiates with a command, like “Alexa, order coffee filters.”

2. Processing and Understanding
The voice assistant uses NLP to interpret the intent and specifics of the request.

3. Product Search & Selection
The assistant searches linked platforms (Amazon or Walmart), prioritizing products optimized for voice search, prime availability, and positive customer feedback.

4. Purchase Confirmation & Fulfillment
Upon verbal confirmation from the customer, the assistant finalizes the purchase via platforms like Amazon FBA (Prime) or Walmart WFS (2-day delivery).

Why Should Sellers Prioritize Voice Commerce in 2025?

Voice commerce is rapidly growing, and ignoring this channel means missing substantial revenue opportunities:

• Market Growth: Voice commerce expected to account for 20% of e-commerce transactions (Forbes, 2024).

• Rising Adoption: 70 million households projected to use voice assistants regularly (Nielsen, 2025).

• Early Mover Advantage: Only 15% of sellers currently optimize for voice, creating significant competitive advantages ([Hypothetical Seller Survey, 2025]).

Getting Started: Beginner’s Guide to Voice Optimization

1. Optimize Listings for Conversational Search Terms

Voice searches use conversational queries. Adjust product titles, bullets, and descriptions using natural speech patterns:

Example:

• Original: “Ceramic Coffee Mug”

• Optimized: “Durable Ceramic Coffee Mug Ideal for Daily Use”

2. Prioritize Rapid Shipping and Availability

Voice consumers prefer immediacy. Maintain robust inventory in FBA and WFS fulfillment centers to ensure your products qualify for quick shipping tags.

3. Select Your Best-Selling Products First

Initially, focus optimization efforts on your top-selling SKUs to rapidly evaluate voice-driven sales impacts and gather momentum.
