An Overview of the Translation Services Market

Translation and interpreter services are two of the jobs that people with skills in multiple languages can target for employment. According to a report by The Business Research Company, the global translation services market was valued at $23.1 billion in 2023. The market is expected to grow at a compound annual growth rate of 4.8% and reach $29.85 billion in 2028. The factors driving the growth in the market include businesses going international, international trade and cooperation, increased global travel, and multilingual content creation. 

The surge in online learning, advancements in translation machines, and the rising demand for non-English languages are driving the translation services market. Online education and e-learning are gaining popularity, especially after the pandemic. Students worldwide are learning new skills and gaining education outside the conventional education environments. According to McKinsey, the enrollment rate in online universities increased by 11% between 2019 and 2020. Translation services are pertinent for e-learning platforms and online universities to provide education for all without a language barrier. Online learning platforms, including Udemy Inc (NASDAQ:UDMY) provide translated transcripts and video lectures to allow users to learn various courses in different languages. 

Additionally, the translation services market is divided into distinct segments, encompassing essential components like translation software and hardware, varied types of translation, and applications across legal, medical, tourism, and banking sectors. The global machine translation market alone is expected to grow at a CAGR of 5.30% between 2024 and 2029, according to a report by Mordor Intelligence. The growth for this segment is attributed to the advancements in computer-assisted tools and translation software. A key advancement is the use of Neural Machine Translation (NMT), which uses artificial intelligence and tons of data to predict the likelihood of phrases and metaphors while translating. In other words, NMT learns the translation patterns using machine learning and improves with the number of translations conducted. Key players such as Google Translate by Alphabet Inc (NASDAQ:GOOG) and Bing Translate by Microsoft Corporation (NASDAQ:MSFT) use NMT to train their translation software.
