Multilingual Toggle Support in Storyline

Hey team,

I’ve created a course in Articulate Storyline with English voiceovers, and I’d like to provide users the option to toggle between English and Spanish. For the Spanish version, I’ve used a different AI text-to-speech tool and not the built-in Articulate text-to-speech feature.

Is there a recommended way to implement a language toggle that would allow users to switch between English and Spanish—ideally changing both on-screen text and audio based on their selection?

Any best practices or guidance on how to set this up using external audio files would be greatly appreciated.
