Last month we spotted Google testing an audio based listen and translate feature for the local panel. It seems Google is now trying this out for standard knowledge panels. These will play an audio clip of the knowledge panel text in English or your local language, even if the language is written in English on the search results page.

Here is a video he shared of it in action:
