I need OCR for multilingual documents with mixed scripts

Yes — for multilingual documents with mixed scripts, you’ll want an OCR pipeline that can:

1. Detect the text regions
2. Identify the script/language per region
3. Apply OCR with the right model per script
4. Preserve layout if the document has tables, columns, forms, or annotations

Good OCR options for mixed scripts

Cloud OCR

These are usually the easiest and most accurate for multilingual documents:

• Google Cloud Vision / Document AI

  • Strong multilingual support
  • Good at mixed Latin, CJK, Cyrillic, Arabic, Devanagari, etc.
  • Better if you need layout extraction too

• Azure AI Vision / Document Intelligence

  • Good multilingual OCR
  • Strong document parsing and form/table extraction

• AWS Textract

  • Good for forms/tables
  • OCR support is decent, though multilingual coverage can vary by use case

Open-source / self-hosted

Best if you need local processing or customization:

• PaddleOCR

  • Strong multilingual support
  • Good for mixed scripts
  • Often a strong choice for production pipelines

• Tesseract

  • Supports many languages
  • Works well in some cases, but mixed-script documents often need tuning and preprocessing

• EasyOCR

  • Simple to use
  • Supports many languages
  • Can work well, but quality varies depending on script and image quality

Recommended approach for mixed scripts

If your documents contain multiple scripts on the same page, the best setup is often:

• Layout analysis to find text blocks
• Script detection on each block
• Per-block OCR using the most suitable language model
• Post-processing for language-specific cleanup

Practical recommendation

If you want:

• Highest accuracy with minimal setup → Google Document AI or Azure Document Intelligence
• Open-source and flexible → PaddleOCR
• Basic offline OCR → Tesseract, but expect more tuning

To choose the best option, I’d need:

• What scripts/languages you expect
• Whether the docs are scanned or digital PDFs
• Whether you need tables/forms/layout preserved
• Whether cloud processing is acceptable

If you want, I can also give you:

• a comparison table
• a recommended architecture
• or a ready-to-run Python example for multilingual OCR.
