When I filled in my profile I indicated I spoke 2 languages. English and Portuguese.
I noticed that you gave options for accents in English but none for Portuguese.
I believe this is not entirely helpful since I believe the overwhelming majority of speakers you are recording in Portuguese are Brazilian.
I am Portuguese from Portugal and therefore my Portuguese clips are considerably different in terms of accent. I believe given the prevalence of Portuguese Brazilian contributions, it would be advisable to further segment people like me into a separate accent.
