Hanzi to Pinyin With Your iPhone Camera

What hanzi and pinyin are

Hanzi (汉字) are the Chinese characters themselves. Each one stands for a syllable and, usually, a meaning. There is no alphabet to sound them out: if you have never seen 鑫 before, nothing in its shape tells you it is read xīn.

Pinyin (拼音, "spelled sound") is the official romanisation of Mandarin Chinese. It writes each syllable with Latin letters and marks the tone with a diacritic. Pinyin is what Chinese schoolchildren learn first, what dictionaries index by, and what you type on a phone to enter characters. It is also the bridge that lets a learner say a word they can see but cannot yet read.

Why tone marks matter

Mandarin has four main tones plus a neutral tone, and the tone is part of the word. The classic example uses the syllable ma:

Some apps write tones as numbers (ma1, ma2). Textbooks, dictionaries and HSK material use tone marks, so that is what HanCam shows. If you are reading pinyin to say something out loud, the mark on the vowel tells you the pitch contour to use.

Simplified vs Traditional characters

Mainland China, Singapore and Malaysia write Simplified characters. Taiwan, Hong Kong and Macau write Traditional characters. Many characters are identical in both; others differ a lot (汉 vs 漢, 车 vs 車).

The good news for pinyin is that both scripts write the same Mandarin words, so the pinyin is the same either way. HanCam reads both scripts; you choose the one you expect to see in Settings so recognition can favour it, and you can switch whenever you cross a border.

Why a camera beats typing

To look up a character you cannot read, you normally have two options, and both assume knowledge you do not have yet:

• Type the pinyin into a dictionary. You need to already know the pronunciation.
• Draw the strokes with handwriting input. You need to know the stroke order, and a menu in a dim restaurant is not a good place to practise.

A camera reader skips both. Optical character recognition (OCR) finds the characters in the image, a converter maps each one to its pinyin, and a translator gives you the meaning. HanCam does all three on the phone, live, without taking a photo first.

How to convert hanzi to pinyin with HanCam

1. Install HanCam from the App Store (iPhone or iPad, iOS 18 or later) and allow camera access when asked.
2. Point the camera at the Chinese text. Fill the frame with the line or block you want to read.
3. Read the panel. HanCam shows the original hanzi, the pinyin with tone marks and the English translation together.
4. Tap to copy or share the hanzi, the pinyin or the English into Notes, Anki, Messages or wherever you keep vocabulary.
5. Reading a screenshot? Use Photo Import to read text from an image you already have.
6. Reading text in another app? Select it, tap Share and choose HanCam to get the pinyin without leaving Safari, Mail or a PDF.

Tips for accurate readings

• Light and steadiness matter more than resolution. Hold still for a second and let the recognition settle.
• Horizontal printed text works best. Vertical text and handwriting are not reliably recognised yet.
• Avoid glare on laminated menus and glossy packaging by tilting the phone slightly.
• Match the script. If you are in Taiwan and see odd readings, check that Traditional is selected in Settings.
• Decorative fonts (calligraphy, brush-style shop signs) are harder for any OCR. Try a printed line of the same text if one exists, such as a menu item below the sign.
• Long paragraphs are easier from a photo or via the share extension than from a moving camera.
