VoxAI – AI Text to Speech, Audio & Summary for Posts for WordPress Plugin Directory

VoxAI adds AI text to speech and an AI-generated summary to your WordPress posts — with a single click. Convert any article into natural audio narration so visitors can listen to your posts or have them read aloud, and give every article a smart AI summary at the top. No recording equipment, no microphone, no manual editing. Powered by the OpenAI text to speech and summarization models.

Readers stay longer. Bounce rates drop. And your content becomes accessible to audiences who prefer to listen — on their commute, at the gym, or while multitasking.

✨ Key Features AI Summary Generator

Uses OpenAI GPT-4o Mini to read your article and write a concise, accurate summary. The summary appears in a collapsible panel inside your post — clean, discreet, and on-brand.

Text-to-Speech Audio Player

Converts your full article into natural-sounding audio using OpenAI’s text to speech (TTS) engine, so readers can listen to your posts or have them read aloud. Six high-quality voices available (Alloy, Echo, Fable, Onyx, Nova, Shimmer). The MP3 is saved to your server — no recurring API call for playback. Great for accessibility and for turning your blog into a podcast-style audio experience.

Reading Time Estimator

Automatically calculates and displays the estimated reading time for every post. Configurable and translatable.

Smart Positioning

Choose to inject the AI Reader widget before the content, after the content, or disable injection entirely and use the shortcodes manually.

📝 Works Where the Official AI Plugin Doesn’t The official WordPress AI plugin is Gutenberg-only. Every feature it offers — title generation, summarization, excerpt, alt text — lives inside the block editor sidebar. Activate the Classic Editor plugin and all of it disappears.

VoxAI is different. It was built to work in both environments from day one:

Gutenberg — Full sidebar panel with real-time generation status, voice selector, and cost estimator.

Classic Editor — Dedicated metabox with exactly the same features: generate summary, generate audio, voice selector, per-post cost display.

If your site runs the Classic Editor — or if you manage a client site that does — VoxAI is the only AI audio and summary plugin that works out of the box, no editor swap required.

🔗 WordPress 7.0 & Official AI Plugin Compatible VoxAI integrates natively with the WordPress 7.0 AI infrastructure:

WP AI Client support — When the site has an AI Connector configured (Settings → Connectors), VoxAI uses it for summary generation without requiring a separate API key. Falls back to your OpenAI key if no connector is configured.

Abilities API — Registers voxai/generate-audio and voxai/generate-summary as discoverable AI Abilities. They appear in the Abilities Explorer and can be triggered by AI agents or automation workflows.

Complements, not competes — The official AI plugin handles text features (title, excerpt, classification). VoxAI adds the one thing it doesn’t have: professional audio narration.

Editor-agnostic — Unlike the official AI plugin, VoxAI works identically with Gutenberg and with the Classic Editor plugin active.

🔧 Minimal configuration required Paste your OpenAI API key in Settings → AI Audio & Summary, choose which post types to activate it on, and you’re done. The widget renders automatically.
