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>
<ul>
<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>

Optional Cloud Storage Services 
This plugin optionally supports uploading audio files to cloud storage services (Amazon S3, Google Cloud Storage, Cloudflare R2) to reduce bandwidth usage on your web server.

<h3>Support</h3>

<h3>Privacy Policy</h3>
This plugin does not collect or store any personal data. Audio files are cached locally on your server. The plugin only communicates with Murf.ai’s API when audio generation is requested manually, through enabled automation, or when generating pre-roll audio from plugin settings.

honzanovacek / Readivo

Readivo Audio Player allows you to add an audio version of your WordPress posts and pages using the Readivo text-to-speech embed script.
The plugin provides a simple integration with minimal configuration:
• Insert the player manually using the shortcode [readivo] 
• Add the player anywhere in content using the Readivo Player Gutenberg block 
• Automatically insert the player at the top or bottom of posts based on plugin settings 
• Limit automatic insertion to posts published after a selected date 
• Assign a specific audio recording to a post using Play ID 
• Customize player text using Default text 
• Control visibility per post using a dedicated editor panel
The player is rendered dynamically on the frontend and does not modify stored post content in the database. 
Audio playback and processing are powered by the Readivo service.

<h3>Usage</h3>
Manual insertion (shortcode): 
– Add [readivo] to the content where you want the player. 
– Optional attributes: 
 – Play ID – use a specific audio recording 
 – Default text – custom player text
Gutenberg block: 
– Add the Readivo Player block anywhere in the content. 
– Optional settings: 
 – Play ID – use a specific audio or uploaded MP3 
 – Default text – custom player text 
– If the block is used, automatic insertion is disabled.
Automatic insertion: 
– Enable “Automatically insert a player into each article” in Settings -> Readivo. 
– Choose position (top/bottom) and post types. 
– Set the date from which posts should include the player.
Per-post control: 
– Use the “Readivo” panel in the editor: 
 – Automatically – follow global settings 
 – Show player – force display 
 – Hide player – disable player for this post 
– You can also set: 
 – Play ID – assign specific audio to the post 
 – Default text – customize player text
Priority logic: 
– Gutenberg block → shortcode → automatic insertion 
– Only one player is rendered per post.
<h3>External services</h3>
This plugin loads an external JavaScript embed script from: 
https://cdn.readivo.app/dist/loader.js
The script renders the Readivo audio player and loads the player endpoint: 
https://cdn.readivo.app/player/
What the service is used for: 
Readivo converts article text into audio and provides an audio player that can play the generated audio on the website. It can also be used to play your own audio files or podcasts — simply upload an MP3 file in the Readivo administration and embed it into your article using a Play ID.
What data is sent: 
When audio generation is triggered, the following data may be sent to the Readivo API: 
– page title 
– page URL 
– a stable custom identifier (post ID based identifier) 
– optionally extracted article text for audio generation
When data is sent: 
No data is sent to the Readivo API when the page loads. 
Data is sent only when a visitor starts audio playback and the audio for the article needs to be generated.
