performance but I feel like this is a much better measure of potentially what the like underlying performance of these systems might be because we're not doing supervised training here and you know yeah and surprisingly we know our models are still worse than people so that kind of shows up here but it also shows a promising trend line where in some cases like there's very domain-specific algorithms for unsupervised translation middlee it's been a year so that speech should be up here now is there like some great follow up work from Ferran well
