NurViewer · OCR & phonetic symbols
IPA phonetic-symbol OCR
A copied dictionary entry is not useful if its pronunciation is wrong. Small marks such as stress and vowel length carry meaning, yet can disappear or be confused with punctuation in a scanned English dictionary.
THE PRACTICAL VALUE
Why this step deserves its own workflow
NurViewer includes a specialised second recognition pass for candidate IPA spans, addressing phonetic letters, primary/secondary stress and length marks. It is designed for printed dictionary and learning material, where these small distinctions matter. Keep the source visible and check a pronunciation before turning it into a study note or flashcard.
A PRACTICAL SEQUENCE
Start with the material you actually need.
Check representative material before deciding how much more to process.
- Select a printed pronunciation line or recognise its page.
- Compare IPA letters, ˈ / ˌ stress and ː length with the source.
- Correct residual errors before saving learning material.
EDITION & SCOPE
Know the scope before you commit.
An internal held-out test of 70 real dictionary crops recorded 90.0% completely correct strings for the specialist network alone. This is a narrow test, not a whole-book or universal accuracy guarantee. Fonts, damage and unusual diacritics remain challenging.
Free has no trial expiry: common-format reading, ordinary PDF annotations and supported ordinary document/image-to-PDF export remain available. Recognition, specialist formats and advanced tools have their own allowances or tier requirements.
Compare Free, Standard and Pro →Images may retain historical layouts. Demonstration books, dictionaries and media are not bundled.
A USEFUL QUESTION
Is this audio recognition or pronunciation scoring?
No. It recognises printed phonetic symbols in images and scans. It does not assess your spoken pronunciation.
CONTINUE THE WORKFLOW
A useful next step.
Keep reading, understanding and organising around the same material.

Multi-column OCR reading order
When OCR reads across two columns as if they were one line, the characters may be correct but the paragraph is nonsense. Dictionaries, journals and reference pages need the reading order to survive recognition.

Images & scanned-page OCR
A photographed handout or scanned page contains words you can see but cannot copy. Retyping the entire page wastes effort when only a paragraph or a few labels are needed.

Vocabulary with context & export
A word list without the sentence that made the word matter is difficult to review. Rebuilding the same entries in a spreadsheet or flashcard application repeats work you already did while reading.
