Thanks for reaching out about this in the Community and welcome.
We can confirm that the option to filter and display podcasts according to a specific language is not available at the moment. But there is already an Idea about something like that here. You can vote for it (by clicking +VOTE) and add your feedback in the comments to stay up-to-date with its developments.
As a heads-up, it's good to know that the higher the number of votes an Idea gets, the more likely it is for the Idea to be implemented. If you also wish to learn more about how your feedback will reach Spotify, feel free to take a look at this article.
Hope you'll find this info useful. Have a nice day!
