At this time, EMO understands only a few programmed languages, but they are limited to specific commands and questions. However, his primary and default language is English, so he will always respond in English.
Here is an image of the EMO Pet App where you can set the specific programmed language you want/choose for him to understand first.
TAKE NOTE AND DO NOT FORGET!
If a different language is chosen and set, EMO will understand only that specific language but will always respond in English.
Best Regards
