Best Document Translation APIs in 2024

What is Document Translation API?

Document Translation uses machine learning and natural language processing (NLP) techniques to identify and translate text from one language to another without the need for human intervention. Document Translation API typically supports multiple languages and can handle various file types, including text files, documents, spreadsheets, presentations, and more.

Performance variations of Document Translation APIs

For all companies who use Document Translation in their software: cost and performance are real concerns. The Document Translation market is quite dense and all those providers have their benefits and weaknesses.

Performance variations across languages

Document Translation APIs perform differently depending on the language of the text and some providers are specialized in specific languages. Different specificities exist

  • Region specialties: some Document Translation APIs improve their machine learning algorithm to make them accurate for text in specific languages spoken in particular countries or regions. For example, some APIs perform well in English (US, UK, Canada, South Africa, Singapore, Hong Kong, Ghana, Ireland, Australia, India, etc.), while others are specialized in Asian languages (Korean, Japanese, Chinese, etc.).
  • Rare language specialty: some Document Translation providers care about rare languages and dialects. You can find Document Translation APIs that allow you to process text in Gujarati, Marathi, Burmese, Pashto, Zulu, Swahili, etc.

Performance variations according to text data quality

When testing multiple machine translation APIs, you will find that providers’ accuracy can be different according to text quality and format.

For example, some Document Translators perform better with text coming from tweets, others perform better with text from scientific papers, others with text from customer reviews, etc. This is explained because of the quality of the text (we can imagine that tweets are lower-quality texts compared to scientific papers or press articles for example).

Performance variations according to fields

Some APIs trained their engine with specific data. This means that some Document Translators may perform well for medical documents, while others perform better for laws and legal documents.

Why choose Eden AI to manage your Document Translation APIs

‍Companies and developers from a wide range of industries (Social Media, Retail, Health, Finances, Law, etc.) use Eden AI’s unique API to easily integrate Document Translation tasks in their cloud-based applications, without having to build their own solutions.

Eden AI offers multiple AI APIs on its platform amongst several technologies: Text-to-Speech, Language Detection, Sentiment Analysis, Logo Detection, Question Answering, Data Anonymization, Speech Recognition, and so forth.

We want our users to have access to multiple Document Translation engines and manage them in one place so they can reach high performance, optimize cost and cover all their needs. There are many reasons for using multiple APIs:

  • Fallback provider is the ABCs: You need to set up a provider API that is requested if and only if the main Document Translation API does not perform well (or is down). You can use confidence score returned or other methods to check provider accuracy.
  • Performance optimization: After the testing phase, you will be able to build a mapping of providers’ performance based on the criteria you have chosen (languages, fields, etc.). Each data that you need to process will then be sent to the best Document Translation API.
  • Cost - Performance ratio optimization: You can choose the cheapest Document Translation that performs well for your data.
  • Combine multiple AI APIs: This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because Document Translation APIs will validate and invalidate each other for each piece of data.
