OpenStreetMap offers a lot of labels in different languages, for points of interest, addresses, etc.
Maybe it’s worthwhile to discuss if Common Voice could source those for pronunciation “sentences”. It might be positive for transcription of addresses or other POIs.
To be honest, I’m not sure if the license is compatible with Common Voice’s public domain policy. Maybe the labels itself are not a level where copyright applies, but IANAL.
Any thoughts welcome.
