Are there differences between the German spoken in Germany, Switzerland, and Belgium that I should consider when finding an interpreter?
The answer to this question is absolutely! There are important differences in the way that German is spoken in different German-speaking countries. For example, Swiss German is greatly influenced by the three other official languages in Switzerland; French, Italian and Rhaeto-Rumantsch. Belgian German has been influenced in a similar manner.
Therefore it is critical that a German language interpreter be selected for the specific audience of German speakers for whom they will be interpreting.
