There is currently no ability for Android app users to access audio for articles that contain a spoken audio version.
Highly recommended article for testing:
Proposed design solutions
1. Show audio icon and "Listen to article" below lead image inline with map/similar pages/page issues if present.
The icon is called "volume up" in the Material icon set:
2. Include access to audio in the 'External links' section of the article
An audio player is also included in this section of an article with a spoken version on Web, Mobile Web and the iOS app.
This is something we could implement as well as design proposal 1 (adding an icon or similar at the top of the article).
