Amazon is now testing a feature called “Hear the Highlights”—AI-generated audio summaries of customer reviews and product descriptions—designed to help shoppers quickly understand the pros and cons of millions of products without sifting through pages of text reviews. This innovation marks a pivotal shift toward voice-first ecommerce on the world’s largest retail platform.
How “Hear the Highlights” Works
On select product pages, the Amazon Shopping app now displays a “Hear the Highlights” button. Tapping it initiates a short audio summary (typically under two minutes) delivered by a conversational AI voice dubbed an “AI shopping expert”. The summary synthesizes thousands of customer reviews, product details, and even external web sources into a concise, easy-to-digest format, highlighting both positive and negative feedback.
The feature is currently available to all U.S. customers on over a million products, with plans to expand further. It’s especially prominent on items that typically require more research before purchase, such as electronics, appliances, and consumer goods.
Why Amazon Is Betting on AI Voices
The move is driven by a desire to cut through information overload and make online shopping more efficient. Amazon’s vast marketplace generates countless reviews daily, making it challenging for shoppers to distill actionable insights—a problem AI audio summaries are designed to solve.
Rajiv Mehta, VP of Search and Conversational Shopping at Amazon, describes the experience as “like having helpful friends discuss potential purchases,” aiming for a natural, conversational tone that mimics real-life discussions.
The initiative also boosts accessibility, offering a new option for visually impaired shoppers and those who prefer listening over reading. Early feedback suggests the feature is popular with users who multitask or shop on the go.
The Technology Behind the Feature
Amazon uses large language models (LLMs) to generate the audio scripts, pulling from product listings, customer reviews, and relevant web sources. The resulting script is then voiced by synthetic AI voices—similar to Alexa—offering a seamless, human-like experience. The process is automated and scales across Amazon’s vast catalog, with summaries dynamically updated as new reviews are posted.

Will AI Summaries Replace Customer Reviews?
Amazon’s audio summaries do not remove or replace written reviews—they simply provide a new way to access the most salient points. Traditional reviews, valued for their authenticity and detail, remain available for those who want them.
However, some experts caution that AI summaries may lack nuance or inadvertently blend marketing language with genuine user feedback, potentially masking subtle issues or biases. There’s also concern that oversimplification could lead to impulsive buying decisions, as audio highlights may not fully capture the complexity of a product’s strengths and weaknesses.
Fake review challenges persist, but Amazon is betting that AI can help users navigate a sea of opinions—though discerning shoppers may still prefer to dive deep into written reviews for specific details or edge cases.
The Bigger Picture: Amazon’s AI Push
“Hear the Highlights” is part of a broader effort to embed AI across the shopping experience. It joins features like the Rufus AI assistant (for product Q&A), Shopping Guides (for research), and Interests (for personalized discovery). Amazon’s aggressive investment in AI infrastructure underscores its commitment to reinventing ecommerce with generative and conversational technologies.
What Comes Next
As the feature rolls out more widely, Amazon plans to fine-tune the AI’s accuracy, tone, and coverage, and could eventually expand it to international markets and additional product categories. Sellers are advised to optimize product listings and reviews for clarity and completeness, as AI summarization depends on high-quality source material.
For now, Amazon’s AI-generated audio reviews represent a bold leap toward a future where shoppers get instant, voice-powered insights at the tap of a button—potentially transforming how millions make buying decisions online.
