The TomTom GO 620 will speak street names if you switch to English but you must select a voice that has that capability. For example, Jane is a voice but she does not speak street names. However, Serena does. Choose a voice that states "Computer voice - reads aloud street names." If you don't find any of the English voices on the GO 620 you buy in Switzerland you will have contact Support and ask them to download one or two voices that read street names. I had to do that after I bought mine.
