<p>This plugin allows you to create text-to-speech podcasts of your posts, with the content from embedded URLs supplied by Readability’s Parser API. It aims to be a open self-hosted re-incarnation of defunct <a href="http://soundgecko.com/" rel="nofollow ugc">SoundGecko</a> service.</p>
<p>When a <a href="https://www.readability.com/developers/api/parser" rel="nofollow ugc">Readability Parser API</a> key is supplied, a post which gets saved with a bare URL as its content will have this content prepended with the content that Readability extracts from the page at that URL. This allows you to import an article’s full contents into your podcast just by saving a post with a URL in its content (e.g. by sharing an article URL to your blog via Jetpack’s <a href="http://jetpack.me/support/post-by-email/" rel="nofollow ugc">post by email</a>).</p>
<p>In addition to supplying a URL for the content you want in the podcast, you can also just add the content directly to the post itself without any corresponding article URL, and this content will be converted to TTS (text-to-speech) audio instead. You can also, of course, attach an MP3 to a post and it will be used for the podcast instead of TTS-generated audio from the post content or enclosed URL.</p>
<p>The TTS audio is generated by a Mac regularly connected to the Internet (e.g. your Mac). It generates the article audio MP3 using the OS X <code>say</code> command. You can configure the voice and the rate for the speech audio generated. (Use of the OS X voice is not required; an alternative TTS solution may be devised instead.) The MP3 gets attached to its corresponding post, being prepended to the post content by means of an <code>audio</code> shortcode.</p>
<p>A new <code>listenability</code> permalink endpoint is introduced which contains the text content of a given post presented in a textual form which can be ready by a text-to-speech (TTS) engine. It is specifically designed to be read by the speech synthesis engine in OS X as it includes <a href="https://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/SpeechSynthesisProgrammingGuide/FineTuning/FineTuning.html" rel="nofollow ugc">embedded speech commands</a>. The RSS2 feed includes a new <code>enclosure</code> element containing the URL for this endpoint with the ad hoc content type <code>text/plain+embedded-speech-commands</code>.</p>
<h4>Restrictions</h4>
<p>Note that the Readability Parser API is freely available for <em>non-commercial use</em>. The article content fetched by Readability and inserted into your posts is copyrighted by their respective authors (attribution gets included in the post content). Likewise, the speech audio generated by OS X is for <a href="http://apple.stackexchange.com/a/43300/28836" rel="nofollow ugc">personal, non-commercial use</a>. It is therefore key that there be <em>no advertising</em> employed on the WordPress install that uses this plugin. Because of the non-commercial and personal usage imposed by these dependencies, it is recommended that this plugin be used on your own personal dedicated podcast blog that is set to block search engines, that is unless you have obtained a commercial Readability license and are not using TTS audio generated by OS X.</p>
<h4>Dependencies</h4>
<ul>
<li><a href="https://www.readability.com/developers/api/parser" rel="nofollow ugc">Readability Parser API</a> key. This can also be supplied in <code>wp-config.php</code> via the <code>READABILITY_PARSER_API_KEY</code> constant.</li>
<li>Mac computer (OS X) that is regularly connected to the Internet (e.g. your computer), with <a href="http://sox.sourceforge.net/" rel="nofollow ugc">SoX</a> installed (e.g. via <a href="http://brew.sh/" rel="nofollow ugc">Homebrew</a>).</li>
<li>(Optional) <a href="http://jetpack.me/" rel="nofollow ugc">Jetpack</a> plugin, for the <a href="http://jetpack.me/support/post-by-email/" rel="nofollow ugc">Post by Email</a> feature.</li>
</ul>
<h4>Extensions</h4>
<p>The plugin includes actions and filters primarily for customizing the formatting of the text for the text-to-speech engine. You may use these hooks to improve how the TTS engine reads the text on a given site, for instance by stripping out footnotes or removing image captions. For an example of such a plugin, see the <a href="https://gist.github.com/westonruter/dfaa45b026a2bb6a36e0" rel="nofollow ugc">sample plugin which improves formatting of Wikipedia articles</a>.</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>Optionally Read the Post Title</h4>
<p>Do you want to use the post title as the first synthesized sentence? Then, use the dedicated settings option to apply this behavior.</p>
<h3>Knowledge Base</h3>
<p>Get started with the plugin or explore the advanced features with the documentation available in the <a href="https://daext.com/kb-category/real-voice/" rel="nofollow ugc">Knowledge Base</a>.</p>
<h3>This plugin can optionally use paid third-party services</h3>
<p>This plugin can optionally use third-party services to perform the text-to-speech conversion. If you configure one of these services and perform a text-to-speech conversion using the tools provided by the plugin, the third-party service will charge you according to their terms.</p>
<h4>When the third-party service “Text-to-Speech AI” from Google Cloud is enabled</h4>
<p>The plugin will use the <a href="https://cloud.google.com/text-to-speech/" rel="nofollow ugc">Text-to-Speech AI from Google Cloud</a> third-party service to perform the text-to-speech conversion when both these conditions are met:</p>
<ul>

<p><a href="https://cloud.google.com/terms" rel="nofollow ugc">https://cloud.google.com/terms</a></p>
<h4>When the third-party service “Text to speech” from Microsoft Azure is enabled</h4>
<p>The plugin will use the <a href="https://azure.microsoft.com/en-us/products/ai-services/text-to-speech" rel="nofollow ugc">Text to speech from Microsoft Azure</a> third-party service to perform the text-to-speech conversion when both these conditions are met:</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>
