The Language Service Industry

Humans have always moved around. And as long as there have been trade and business, there has been multilingual communication.

The language service industry is the business activity that helps others to communicate across linguistic and cultural barriers. In recent times, the need for language services has grown rapidly because of the internet, globalization of business, increased government requirements, diversifying communities, and a more interconnected world population. Some new technological products have helped our industry innovate. But complete and trusted language solutions still depend on comprehensive services, and the companies that have decades of expertise in what you need.


Some services in the industry include:


Converting written text from one language (source) to another (target), keeping the same information, style, and tone.  


Rendering spoken or signed communication between users of different languages.



Adapting content (often websites and software) for a specific locale or market to ensure that it is appropriate for the target audience linguistically, culturally, politically, and technically.


Converting audio recordings in one language to written text in another language.


Adding text to video that displays the audio track either verbatim, summarized, or translated.


Creating a new audio track for video, either to add a disembodied voice or narration (voiceover), or to replace the voices of the original actors with voices in a different language (dubbing).

Language Training

Helping others acquire skills in a second or foreign language using a coordinated curriculum and process.

Language Testing

Evaluating or measuring an individual’s ability to use a particular language effectively, sometimes for specific purposes.
