This extension plays audio description track elements of HTML5 videos via the Chrome text to speech extension. For the extension that plays via screenreader, https://chrome.google.com/webstore/a/google.com/detail/mipjggdmdaagfmpnomakdcgchdcgfbdg

Use this extension if you are not using any screenreaders or are using a screenreader that does not support the other extension, "HTML5 Audio Description (via screen reader)" https://chrome.google.com/webstore/a/google.com/detail/mipjggdmdaagfmpnomakdcgchdcgfbdg. and still want audio descriptions. Also works well as a developer tool. Note: - this extension doesn't use screenreaders to render the audio descriptions, so there may be a possibility of overlap in speech of this extension and speech of the screenreader.

By default, Chrome will speak using your operating system's built-in speech synthesis (available on Windows, Mac OS X, and Chrome OS), or you can install additional text to speech voice extensions from the Chrome Web Store.

Languages supported:
- depends on text to speech voices installed on your system

Keyboard shorcuts:
For keyboard shortcuts, press alt + h while on a webpage or alt + ? while focused on a video; or refer to the options page of the extension.
