All audio stories and resources on Listenwise are in English. We do not have any podcasts in Spanish or any other language.
On student assignments, the built-in blue Texthelp toolbar offers Spanish translations for single words and longer phrases. If you click the Play button on the toolbar pop-up, it will read it aloud in Spanish. You can learn more about these features in this article.
If you need to translate a podcast into another language, you can download the transcript and use a translation tool.
