You can now discover, see and listen to audio podcasts directly in search. This was part of the overall I/O keynote from Wednesday, but launched yesterday morning and you can I can see it on both desktop and mobile Google search.
Didn't we see podcasts in search a couple years ago? Yes, but that was just based on the Podcast structured data elements, not based on how Google transcribes the audio within the actual podcast's content. Previously, Google was not able to understand the words within a podcast, but now they can.

Update: If it is true that they are still not surfacing audio content through transcription, then nothing is new:
