<p><strong>Speechable</strong> transforms your WordPress content into natural-sounding audio using AI-powered text-to-speech technology. Speechable uses Piper TTS, an open-source neural text-to-speech engine that runs in your browser.</p>
<h4>Third-Party Service</h4>
<p>This plugin uses the following third-party services for text-to-speech functionality:</p>
<p><strong>Piper TTS Web Library</strong></p>
<ul>
<li>Service Provider: <a href="https://github.com/Mintplex-Labs/piper-tts-web" rel="nofollow ugc">Mintplex Labs</a></li>
<li>Library CDN: jsDelivr (https://cdn.jsdelivr.net/npm/@mintplex-labs/piper-tts-web)</li>
<li>ONNX Runtime CDN: Cloudflare (https://cdnjs.cloudflare.com/ajax/libs/onnxruntime-web)</li>
<li>WASM Phonemizer CDN: jsDelivr (https://cdn.jsdelivr.net/npm/@diffusionstudio/piper-wasm)</li>
<li>Voice Models: Downloaded from <a href="https://huggingface.co/diffusionstudio/piper-voices" rel="nofollow ugc">Hugging Face</a></li>
<li>Terms of Service: <a href="https://github.com/Mintplex-Labs/piper-tts-web/blob/main/LICENSE" rel="nofollow ugc">MIT License</a></li>
</ul>
<p><strong>Whisper (Word Timestamps)</strong></p>
<ul>
<li>Service Provider: <a href="https://huggingface.co/docs/transformers.js" rel="nofollow ugc">Hugging Face Transformers.js</a></li>
<li>Library CDN: jsDelivr (https://cdn.jsdelivr.net/npm/@huggingface/transformers)</li>
<li>Model: Xenova/whisper-tiny.en (~75MB, downloaded on first use)</li>
<li>Purpose: Provides accurate word-level timestamps for synchronized highlighting</li>
<li>Terms of Service: <a href="https://github.com/huggingface/transformers.js/blob/main/LICENSE" rel="nofollow ugc">Apache 2.0 License</a></li>
</ul>
<p><strong>What data is transmitted:</strong></p>
<ul>
<li>The TTS library and ONNX runtime are loaded from CDN when generating audio</li>
<li>Voice model files are downloaded from Hugging Face when first using a voice</li>
<li>Whisper model is downloaded for word timestamp extraction (first use only)</li>
<li>Your content text is processed locally in your browser and is NOT sent to any external server</li>
<li>Once downloaded, all resources are cached locally in your browser</li>
</ul>
<p><strong>Why external resources are required:</strong></p>
<p>The text-to-speech engine requires machine learning runtime (ONNX) and voice models that are too large to bundle with the plugin. These are loaded on-demand from CDN services, similar to how Google Fonts or other web services work. This is a service-based approach that keeps the plugin lightweight while providing high-quality AI voices.</p>

This upgraded edition includes more text-to-speech converters (other integrations for Amazon Polly and ElevenLabs are available), the ability to make the audio files downloadable by the visitors, customizable audio player placement using a shortcode, and more.</p>
<h3>Key Features</h3>
<h4>Automatically Add the Audio Player</h4>
<p>The plugin automatically adds an audio player at the beginning of the articles. Note that from the plugin options, you can configure post types on which the audio player should be displayed.</p>
<h4>Manually Generate the Audio Files</h4>
<p>We have included a dedicated post sidebar section where you can create a new audio version of the post, update the existing audio version, or delete the audio data.</p>
<p>The website administrator, the editor, or other authorized users can at any time access to this area.</p>
<h4>Monitor the Presence and State of the Audio Files</h4>
<p>The plugin adds a new column named “Audio File” to the posts menu (and to the admin menu of all the other enabled post types). Here, you can verify if a specific post has its related audio version and if this version is up to date with the post.</p>
<h4>Customizable HTML Audio Player</h4>
<p>The plugin generates a custom audio player built with HTML and the browser API. You can customize the style of the player (color, typography, shadows, etc.) using the plugin options.</p>
<h4>Responsive Audio Player</h4>
<p>The audio player is responsive, and you can specify the breakpoint used to switch from the desktop to the mobile version with a dedicated option.</p>
<h4>Supports Plain Text and SSML</h4>
<p>You can generate the audio version of an article from plain text or SSML.</p>
<p>In the case of SSML, the supported tags vary depending on the selected text-to-speech converter.</p>
<h4>Add Additional Text Before or After the Player</h4>
<p>Use the dedicated options to configure the message displayed before (or after) the player. You can set messages like “Listen to this article”, “This article is also available in an audio format”, etc.</p>

<h4>When the plugin performs a text-to-speech conversion</h4>
<p>In the contexts described below, the plugin performs a text-to-speech conversion. Note that with a third-party service enabled, this involves sending text/SSML to the third-party service API (on a remote server) to retrieve the audio data.</p>
<p>Text-to-speech conversions are performed when you click the <strong>Generate file</strong> button in the <strong>Audio File</strong> post sidebar section. For <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor</a> users, the text-to-speech conversions are performed when you click the <strong>Generate file</strong> button in the <strong>Audio File</strong> meta box.</p>
