iPhone keyboard switches to Spanish

Hi there, Anastasius1!
Thanks for reaching out to the Apple Support Communities! It sounds like you are having an issue with the your keyboard switching to Spanish when you use Dictation or type and I’m happy to help! First, I recommend checking out this article with steps for How to force an app to close on your iPhone, iPad, or iPod touch and quit the apps running in the background. Once they are closed, Restart your iPhone, iPad, or iPod touch and test to see if the issues are still going on.
Let me know the results and have a great day!

The globe icon is for doing just that - switching between different keyboards. I have English, Spanish, French, Emoticon and other keyboards enabled. If you wish to add or delete keyboards, go to Settings/General/Keyboard/Keyboards and then either click on Edit and delete to delete the Keyboard(s) you don't want, or click on "Add New Keyboard" to add another one
