Hi Sarahyusuf,
Thank you for letting me know your concerns about changing the language in your Google Home Mini, but don't worry I'm here to assist you.
You can easily change its language to match yours, or even add a second language for a bilingual experience. Change your Assistant's language will affect all your linked Google Nest and Home devices. It might take about a day for the new language to appear on all of them.
Language support can vary depending on your device and location. Make sure your desired language is available before switching.
Regards,
Daniel.
