You can do both. Models trained to receive and predict audio tokens alongside text are coming. You could just add such data as part of training.
>Does that get us any closer to translating it. NO, because without shared context to start building connections and relationships its highly unlikely that were going to find commonality.
If you trained it alongside human languages then shared context(if available) will be figured out by the model. They'll coalesce in the same shared space the way they do for human languages. Enough to translate without examples instead of just speak? Perhaps - it's not like there are examples in the training set for every lang to lang combination modern models are capable of translating.
