I know Germany dub most video, but wouldn't a seven year old be able to read subtitles? It's a great way for her to learn English, it's how most Swedes learn it before starting school. I think there's a pretty strong correlation between countries' average English proficiency and how common dubbing is.

Edit: I forgot to mention that the samples on the website is impressive and well made. How do you do the speaker diarization and voice cloning?
