Customer support teams typically handle hundreds of calls daily, and most callers prefer to voice their inquiries and concerns in a language they’re more comfortable with. Since customer communications and support channels are becoming more globalized, ensuring that each and every customer receives help in their preferred language has become a necessity for call centers to thrive.
This is where interpretation services come in. Often erroneously referred to as “translation services,” these services provide a solution for one of the most common challenges encountered by multilingual call centers worldwide.
Challenges Encountered by Multilingual Call Centers
Language barriers between customer support teams and callers are one of the leading causes of hang-ups and, by extension, lost customers. Finding the right interpreter to communicate with a caller effectively isn’t as easy as it looks, either, since they might struggle with integrating into an already-existing process and workflow, creating more problems in the long run.
Connection times also play a significant role in solving the problem, as customer support agents have limited time when on the line. This requires them to balance their time communicating with callers, noting problems, assisting, and accessing interpreting solutions.
To that end, we’ve collected a list of reliable call center translation service providers you can work with in 2025:
