We have supported many customers in their efforts to publish their podcast in another language. We don't offer any audio language translation features within ART19 itself but wanted to outline the best course of action for customers interested in expanding their podcast to another language. On ART19, there are two options we recommend:
1) Create a new series that is effectively just a language translation version of your current existing series. To request a new series profile please fill out our new series request form: ART19 New Series Request Form
2) You could also utilize an alternate feed for this use case, effectively creating an alternate feed(s) for the other language(s) you are interested in publishing your content in. For example, your primary feed hosts your podcast in its local language, while the alternate feed is for the Spanish audio version. For more information on alternate feeds, please reference our help center article: Feeds
