ListenUp is a powerful WordPress plugin that adds text-to-speech functionality to your posts and pages. With just a few clicks, you can generate high-quality audio versions of your content using Murf.ai’s advanced AI voices.
<h4>Key Features</h4>
<ul>
<li>Easy Audio Generation: Generate audio for any post or page with a simple click</li>
<li>Murf.ai Integration: Uses professional AI voices for natural-sounding audio</li>
<li>Gen2 API Controls: Tune reusable Murf audio with locale, format, response mode, duration, timing metadata, speed, pitch and pauses</li>
<li>No FFmpeg Required: Ideal for hosting environments where FFmpeg is not available or restricted</li>
<li>Smart Caching: Audio files are cached locally to save API credits</li>
<li>Hands-Off Generation: Queue audio automatically when content is published and backfill recent posts on a schedule</li>
<li>Intelligent Chunking: Long content is automatically broken into manageable chunks</li>
<li>Seamless Playback: Multiple audio chunks play continuously without interruption</li>
<li>Leech Protection: Secure audio delivery prevents unauthorized direct file access and hotlinking</li>
<li>Download Control: Restrict downloads to logged-in users or disable downloads entirely</li>
<li>Flexible Placement: Choose where to display the audio player (before/after content)</li>
<li>Shortcode Support: Use [listenup] shortcode to place players anywhere</li>
<li>Accessibility First: WCAG-compliant audio player with keyboard navigation</li>
<li>Mobile Responsive: Works perfectly on all devices</li>
<li>Admin-Friendly: Simple settings page with clear instructions</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Setup: Enter your Murf.ai API key in the plugin settings</li>
<li>Generate: Use the meta box on any post/page, or enable background generation on publish</li>
<li>Display: Audio players appear automatically or via shortcode</li>
<li>Listen: Visitors can play, pause, and download audio content</li>
</ol>
<h4>Advanced Features</h4>
Content Chunking: For posts that exceed Murf.ai’s API limits, content is automatically broken into smaller chunks. Each chunk generates a separate audio file, but the frontend player seamlessly plays all chunks in sequence without interruption.
Audio Concatenation: When downloading audio content that has been chunked, the plugin automatically concatenates supported stream-friendly formats into a single file, so listeners do not have to manage separate chunks.
Bulk Cloud Migration: Upload existing local-only audio files to configured cloud storage from the Audio Library without regenerating audio. Large backlogs run in small browser-safe batches, track remaining work by post, and upload the canonical playable audio file instead of internal chunk files.
Murf Gen2 Controls: Choose URL or direct base64 responses, set single-file target durations, request word timing metadata, tune speed/pitch/variation, and use <code>[pause 1s]</code> tags in content or pre-roll scripts. ListenUp still caches generated files locally so audio is reused instead of regenerated on every play.
No FFmpeg Dependency: Unlike many audio plugins, ListenUp doesn’t require FFmpeg, making it perfect for shared hosting environments, managed WordPress hosts, or any situation where FFmpeg is not available or restricted.
Leech Protection: Audio files are served through a secure PHP proxy with cache-safe per-file tokens, preventing unauthorized direct access and hotlinking without embedding expiring nonces in cached article HTML. All audio is delivered via WordPress AJAX endpoints with proper HTTP range request support for smooth seeking. This server-agnostic solution works on Apache, Nginx, IIS, and any PHP-capable server without requiring special server configuration.
<h4>Perfect For</h4>

<li>Bloggers who want to offer audio versions of their posts</li>
<li>Content creators looking to improve accessibility</li>
<li>Websites targeting mobile users who prefer audio content</li>
<li>Educational sites with long-form content</li>
<li>News sites wanting to offer audio news</li>
</ul>
<h4>Accessibility Features</h4>
<ul>
<li>Full keyboard navigation support</li>
<li>Screen reader compatible</li>
<li>High contrast mode support</li>
<li>Reduced motion support</li>
<li>Proper ARIA labels and descriptions</li>
</ul>
