Telugu OCR Guide — Extract Text from తెలుగు PDFs & Images
Telugu is a Dravidian language written in an abugida where consonant-vowel combinations form complex glyphs. Generic OCR engines often struggle with the intricate vowel marks and conjuncts that define Telugu script.
This guide explains how to extract accurate Telugu text from scanned documents and images while preserving every vowel sign and conjunct.
Why Telugu OCR Is Complex
Telugu vowel signs attach around consonants and can stack, while conjunct consonants merge into ligatures.
- Vowel signs (talakattu) appear above, below, or beside consonants.
- Conjunct consonants (gunintam) merge multiple consonants into one glyph.
- Visually similar characters like క/ఘ and త/థ are hard to distinguish.
- Mixed Telugu-English documents require script switching.
- Low-resolution scans lose small marks above rounded characters.
