This plugin will allow WordPress users to automatically provide an audio version of their written content, using the HearWho Text to Speech engine. Upon creation of a new blog post a “Listen to this text” link will be prepended to blogs and allow the user to listen to the blog entry rather than read it. This is useful for folks trying to read-content while on the go, for visually impaired users visiting your blog, or for those that would just rather have content read to them, rather than read it directory. Users of this plug must obtain a free license key on https://hearwho.com to use the functionality. A free key is valid for use on conversion of up to 3,000 characters (most blog posting are usually under 3,000 characters). If you need more than this, we charge a very modest fee to substantially increase those limits (3.99 USD/month).
Instructions:
<ol>
<li>Install plugin through your WordPress administration page. (Or, extract the contents of the zip file and upload it directly into the plugins folder: “/wp-content/plugins/”).</li>
<li>Next, activate plugin and go to the HearWho Settings page in your WordPress site and enter your API Key. (If you need an API key, create a free account on HearWho.com and visit this same page to see your key.)</li>
<li>Now, every new blog post you publish, or anytime you update an existing blog post, a high quality “spoken version” of your posting will be prepended to your posting.</li>
</ol>
Note: the plugin will not retroactively add speech versions of existing blog posts. If you would like to add an audio version for an older post, simple open up the edit screen (not quick edit) as you normally do for an older post, an simply click the update or save button.

Speechable 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.
<h4>Third-Party Service</h4>
This plugin uses the following third-party services for text-to-speech functionality:
Piper TTS Web Library
<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>
Whisper (Word Timestamps)
<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>
What data is transmitted:
<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>
Why external resources are required:
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.
