內容簡介
此外掛讓您能夠使用 Readability Parser API 提供的嵌入式 URL 內容建立文章的語音播客。它旨在成為已終止的 SoundGecko 服務的開放式自托管版本。當提供 Readability Parser API 金鑰時，保存只有 URL 內容的文章會在此內容前加上 Readability 從該 URL 頁面提取的內容。這使得您能夠通過在內容中保存 URL（例如通過 Jetpack 的郵件發布）將文章的完整內容導入播客。除了提供播客內容的 URL，您還可以將內容直接添加到文章本身中，而不需要對應的文章 URL，這樣的內容將轉換為 TTS（文本到語音）音頻。當然，您還可以將 MP3 附加到文章中，它將用於播客，而不是從文章內容或附帶的 URL 生成 TTS 音頻。TTS 音頻使用常常與互聯網連接的 Mac（例如您的 Mac）生成，它使用 OS X say 命令生成文章音頻 MP3。您可以配置所生成語音音頻的語音和速度（無需使用 OS X 語音; 可以使用替代 TTS 解決方案）。MP3 附加到相應的文章中，通過 audio 短碼将其前置到文章內容。
引入新的 listenability 永久鏈接端點，其中包含以文本形式呈現給文本到語音（TTS）引擎閱讀的特定文章的文本內容。它專為帶有嵌入式語音命令的語音合成引擎完成，是 OS X 引擎閱讀的文本格式，RSS2 源包含一個新的 enclosure 元素，其中包含此端點的 URL，採用的是即席內容類型 text/plain+embedded-speech-commands。
請注意，Readability Parser API 供非商業使用免費使用。由 Readability 傳回並插入文章的文章內容受其各自作者的版權保護（屬性包括在文章內容中）。同樣，OS X 生成的語音音頻僅供個人非商業使用。因此，使用此插件的 WordPress 安裝上不應該使用廣告。由於這些依賴性所強加的非商業和個人用途，建議建立專用的播客博客並服務於自己，設置為不向搜索引擎公開，除非您已經獲得商業讀取許可證，並且不使用 OS X 生成的 TTS 音頻。
依賴項包括 Readability Parser API 金鑰（可以通過 READABILITY_PARSER_API_KEY 常量提供到 wp-config.php 中），定期連接到互聯網的 Mac 電腦（例如您的電腦），安裝了 SoX（例如通過 Homebrew 安裝），還有 Jetpack 插件（可選），用於通過電子郵件發布文章。

原文外掛簡介
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 SoundGecko service.
When a Readability Parser API 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 post by email).
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.
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 say 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 audio shortcode.
A new listenability 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 embedded speech commands. The RSS2 feed includes a new enclosure element containing the URL for this endpoint with the ad hoc content type text/plain+embedded-speech-commands.
Restrictions
Note that the Readability Parser API is freely available for non-commercial use. 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 personal, non-commercial use. It is therefore key that there be no advertising 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.
Dependencies
Readability Parser API key. This can also be supplied in wp-config.php via the READABILITY_PARSER_API_KEY constant.
Mac computer (OS X) that is regularly connected to the Internet (e.g. your computer), with SoX installed (e.g. via Homebrew).
(Optional) Jetpack plugin, for the Post by Email feature.
Extensions
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 sample plugin which improves formatting of Wikipedia articles.
See the plugin source code to see which additional plugin hooks are available.
