There is no specific mention in the provided knowledge set about a mandatory monthly membership or subscription being required for the language translation feature of the Liberty earbuds. It's best to consult the product's detailed user manual or associated companion app (e.g., Soundcore app) for confirmation on whether additional subscriptions are needed for specific features like translation.

I couldn't find specific details about whether the "Soundcore - by Anker Liberty Buds" supports translation to Swahili. You may need to verify this in the product's specifications or features on its official sales page or explore its companion translation functionality through connected apps.
