Whether you’re running a business, working in education, or simply communicating internationally, file translation is key. But here’s the challenge: translating different file formats – like audio, PDFs, JSON files, images, and subtitles – can feel complicated.
Each type of file brings its own set of challenges, and figuring out how to translate them can be confusing. But don’t worry!
In this guide, we’ll walk you through the best methods and tools for translating a variety of file formats so you can easily share your content in any language.
Translating audio files
Translating audio files involves various challenges, particularly in comprehending various accents, local dialects, and industry-specific terminology. Translating audio files may be automated or done by humans. Both of them have advantages and disadvantages based on how much accuracy you require.
1. Automated speech-to-text + machine translation
This is a widely used choice for fast and easy audio translations. You first use software to translate the audio into text, and then the text can be translated with machine translation tools like Google Translate or DeepL. This process is convenient and quick, but less suitable for official or legal translations.
2. Human transcription and translation
When precision matters, hiring a professional transcriptionist to transcribe audio into text and then having it human-translated is the optimal choice. Human translation services are particularly necessary for trade-specific language or legal and technical writings because machines can get context or linguistic nuances wrong. While this is more costly and time-consuming, it delivers much higher accuracy.
Best devices for translating audio
- Google Translate: Fast, but only workable for elementary translations.
- Sonix: Very good transcription service with integrated translation features.
- DeepL: High-quality machine translation with excellent accuracy.
- Otter.ai: A good choice for transcription, particularly for meetings or interviews.
How to translate audio files
- Step 1: Transcribe audio into text using transcription software.
- Step 2: Translate the text using human or machine translation services.
- Step 3: (Optional) Convert the translated text into audio using text-to-speech software for multilingual audio outputs.
Translating from an audio file
Direct translation from an audio file without first transcribing it into text is usually more complicated. The process is one of translating as one hears, which is not easy where one has to contend with muffled speech, technical terms, or noise in the background. AI tools will try to translate directly from audio, but for very accurate outcomes, transcription and then text translation is often the best way.
Translating pdf documents online
PDFs are one of the most frequently translated business, legal, and academic documents. Yet, not all PDFs are equal – some are text-based and can be easily extracted and translated, but others are scanned and need Optical Character Recognition (OCR) to be applied prior to translation.
Why translate pdfs?
- Business: Translating business reports, contracts, and marketing materials helps to ensure that there is good communication with global clients.
- Legal: Critical documents such as agreements and contracts need to be properly translated to prevent legal misinterpretations.
- Academic: Research reports, books, and other study materials are commonly translated to appeal to a worldwide market.
- Personal: Individual documents such as certificates and letters also need to be translated when immigrating or traveling overseas.
PDF translation methods
- Text-based PDFs: Can be easily translated using copy-paste or automated translation.
- Scanned PDFs: OCR technology must be used to pull the text out of the scanned image before translation.
Best pdf translation tools
- Google Translate: Suitable for basic, text-based PDFs.
- DeepL: Offers better translation for text-dominant documents.
- DocTranslator: Expert document translation tool designed for professional use.
How to translate a pdf document online
- Step 1: Upload the PDF to your preferred translation tool.
- Step 2: Select the target language for the translation.
- Step 3: Download the translated document and check it for any required edits.
Translating JSON Files
JSON (JavaScript Object Notation) files are widely employed in web development, application development, and APIs. JSON files have structured data that must be carefully preserved when translating to prevent code or format breakage. Translating JSON files is a challenge to ensure the content is properly translated without losing the JSON structure.
What is JSON Used for?
- App Development: JSON files usually hold the user interface text, error messages, and so on that need to be translated for various regions.
- Website Localization: Multilingual websites utilize JSON files to store translations for each language version.
- APIs: When APIs interact with global applications, the text in JSON files can require translation.
Best software for translating json files
- Localazy: A software specifically used to translate software content, such as JSON files.
- POEditor: A teamwork tool used to manage and translate JSON files.
- Google Translate API: Provides programmatic access to translating JSON data.
Translating text from images to english
The requirement of translating text from images is frequent – be it a menu, road sign, business document, or educational document. The translation process entails a process of extraction of the text from the image using OCR technology, followed by translation of the extracted text.
Why translate text from images?
- Business Communication: International travelers for business could require translating signs, documents, and brochures.
- Documents: Official documents sometimes arrive in the form of images and are required to be translated.
- Menus and Signs: While traveling, having signs or menus translated helps achieve communication more easily.
Best tools for image translation
- Google Lens: An easy tool for image text translation using your mobile phone.
- Yandex Translate: Offers several languages to translate and is handy with images.
- Adobe Scan: Blends strong OCR functionality with translation features.
Translating srt (Subtitle) files
Subtitle translation is critical in making multimedia material accessible to an international audience. For online content, movies, or educational videos, subtitle translation (SRT) files make it possible for audiences in other languages to access the material.
Why translate subtitles?
Subtitles enhance video content for non-native speakers and hearing-impaired viewers. Whether it’s a movie, an educational video, or web content, subtitles in several languages expand your audience.
Best tools for translating subtitles
- Google Translate: Simple, free subtitle translation.
- DeepL: Improved machine translation of subtitles.
- Aegisub: A software especially made for producing and translating subtitle files.
Translating SRT Files
- Open the SRT file using a text editor or translation software.
- Translate each line, with timing remaining consistent with the video.
- Save the translated file and play it with the video to check if all is correctly synchronized.
File translation: manual vs. automated
When it comes to translating any file type – be it audio, PDF, JSON, image, or subtitles – you have two broad options: manual or automated translation.
- Manual Translation: Human translators perform it, making it more accurate and reliable but costlier and time-consuming.
- Automated Translation: Quick and inexpensive but error-prone, particularly for complicated documents. It’s ideal for non-critical translations or when speed is more important than accuracy.
Summary
File translation is now a requirement in the world we live in today. Whether you want to translate an audio file, PDF file, JSON file, image text, or SRT subtitles, there is a way that works for you. Knowing the strengths and limitations of various translation tools and techniques allows you to select the most appropriate technique for your particular application. Automated tools are excellent for speed, but when precision matters, human translators are your best option.
