The challenge of language barriers in the tourism industry

The ever-present language barrier has long been a headache in the global tourism industry. It leads to misunderstandings, limits cultural exchanges, and hampers overall travel exposure. Destination management organizations (DMOs), attractions, tour operators, and travel businesses are unable to cater to a diverse audience when they can't communicate effectively with potential visitors who speak different languages. Likewise, visitors face difficulties understanding local languages, making it difficult to navigate new cities and appreciate historical attractions in context.

However, traditional translation methods can be costly, and time-consuming, and still may end up compromising accuracy and cultural context, leading to misinterpretation.

AI-powered translation tools are addressing these challenges in the best possible manner.

AI translation catering to the needs of the travel market

Machine translation services such as the already-mentioned DeepL, excel in understanding and translating texts, not just on a word-for-word basis, but by comprehending the context and subtleties of the language, ensuring that content resonates with visitors worldwide.



Here are the standout features that position DeepL (also used by SmartGuide) as one of the world's best AI-powered translators.

1. The cost efficiency and accuracy

The accuracy range of Neural Machine Translation (NMT) is 70-99%, depending on the language combination.

When it comes to cost-efficiency, the price per machine-translated source word is a fraction of the traditional human translation. However, for optimal results, the translation process usually consists of a combination of machine translation that is checked and edited by a human. Such an AI-assisted human translation process can be up to 70% cheaper compared to manual translation while delivering comparable results. The economic advantage of AI-assisted translation enables the inclusion of more language translations within a set budget. At SmartGuide, this enables an extremely cost-effective creation of multilingual digital travel guides that cater to various audiences.
