This release is GREAT for 1 use case: is to do language learning for KIDS! Since it supports other languages , i can have my young ones go at it talking favorite pokemon, etc. But in a foreign language. That is great. Now if it supported mic input on a foreign language (that may be an edge browser microphone limitation) they could have a full conversation, which would be incredible!
I ask this as someone with no kids who is working on a language learning app that does essentially what you're talking about [1]. We have only done a little bit of red-teaming, but I'm sure there are ways kids could talk about topics that at least some parents may not want.
