Most languages that reached enought number of sentences to be in the voice phase (more than 5000) were the ones that provided that many strings during the campaign we run a few months ago. Unfortunately Spanish did not gather a lot (just a few hundreds).
There are other languages that were using github pull requests but currently we have found that some of them will need a cleanup in order to be useful (for the machine learning engine) and that’s why from now on we want to make sure the sentences we include are properly reviewed to avoid having to do another cleanup in the future.
The good news is that this should not stop any efforts collecting sentences, in early January, as soon as we have the tool ready we will be able to mass import them and use the tool for doing a proper review and approval.
