<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>
