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.


The Need for Language Services

Both globalization and immigration are driving growth of the language services industry. More than 350 different languages are spoken in the U.S. alone. Due to this diversity and the sustained increases in the number of persons who don’t speak English in the United States, employment of interpreters and translators is projected to grow 19% by 2028 according to the Bureau of Labor Statistics.

The U.S. Census Bureau states that 67.3 million persons in the U.S. speak a language other than English at home which has more than doubled in the last 30 years. More than 25 million in the U.S. are classified as Limited English Proficient (LEP). LEPs do not speak English as their primary language and have limited ability to read, write, or understand the language to communicate effectively. And the greatest language needs vary greatly in different regions, different industries, and for different purposes.


1 out of every 5 people in the US
speaks a language other than English at home


Limited English speaking and deaf and hard of hearing individuals are entitled to services by law. Such laws include Title VI of the Civil Rights Act; Americans with Disabilities Act; HIPAA; Affordable Care Act/Section 1557; and the Fraud, Waste, and Abuse Act.

Language services are offered, not only if it’s mandatory, but also because it’s the right thing to do. Effective communication helps any type of organization improve their customer/patient satisfaction, increases productivity of staff, builds loyalty and enhances their image in the communities they serve. Many businesses also use language services to help reach more potential customers, or provide better support to existing customers.
