How to Add Audio to Shopify Product Pages (Listen Button)

Product descriptions are written to be read, but a growing share of your shoppers are not reading: they are on a phone, in motion, or living with low vision, dyslexia, or plain screen fatigue. Audio meets them where they are. Podcasts and voice interfaces trained people to expect a play button; product pages are simply late.

What audio actually does for a store

• Accessibility that shows. Screen readers exist, but a visible Listen button serves shoppers who never install one: low vision, dyslexia, older customers, second-language shoppers who process spoken English more easily than boutique copywriting.
• Mobile attention. A shopper who taps play keeps your page open for the duration of the narration. That is dwell time you did not have, on the device where reading long copy is least likely.
• Copy discipline. Descriptions written to be heard tend to be better: rhythm and concrete detail survive narration; keyword stuffing does not.

The three ways to do it on Shopify

1. Record and upload audio files manually

Record narration, host the files, embed an audio player per product via metafields and a theme block. Full creative control, and completely unmanageable past a handful of products: every copy edit means re-recording.

2. Browser text-to-speech via custom theme code

The Web Speech API can read page text aloud with a small script. It is free, but voice quality varies wildly by browser and device, iOS handling is quirky, and you own the maintenance in your theme forever.

3. An app that generates and serves narration

This is the job Miko AI Descriptions & Narrate was built for. It generates natural-sounding narration for your product descriptions, and the Listen button installs as a theme app embed: one toggle in the theme editor, no code changes, and it lazy-loads so nothing is added to the initial page load. Because the same app writes and improves descriptions in bulk, the narration always matches the current copy; edit the description and the audio follows.

Implementation notes that matter

• Placement: the button belongs directly above or below the description it reads, not floating over the gallery.
• Performance: audio must load on tap, never on page load. Test your Core Web Vitals before and after; a correct implementation moves nothing.
• Voice consistency: one voice across the catalog. A different voice per product reads as broken.
• Measure it: watch play rate and post-play add-to-cart on your top 20 products. With Sidekick connected, "how many products have narration?" is a one-line question in the admin.
