Features

Polyphonic Pinyin Annotator is a browser-based Chinese pronunciation reference for teachers, editors, narrators and language learners who need to check multi-read characters without sending a manuscript to a server. Paste simplified or traditional Chinese text and the tool walks through it character by character, using 456 hand-built multi-character collocation rules plus a 172-entry pronunciation map to pick a reading for common polyphonic Hanzi. Matches are shown as orange highlighted characters in an HTML ruby layout or as inline parentheses; every highlighted character can be clicked to cycle through its other readings when the automatic choice is not the one you need. The tool reports how many polyphonic, rare and dictionary-missing characters it found, and exports the annotated result as copied HTML ruby, copied inline text, or a downloaded .txt file. It is deliberately a transparent rule-and-dictionary tool rather than a black-box language model: you can see which characters were treated as ambiguous, correct them yourself, and keep the final proofread under human control. Everything runs locally in the browser, so student names, unpublished manuscripts and client scripts are not uploaded for annotation.

Polyphonic Pinyin Annotator turns Chinese text into ruby or inline pinyin, using 456 collocation rules to choose readings for common multi-read characters and letting you click any highlighted character to override the result.

When You Need This

Common pain points this tool solves

1. A primary-school Mandarin teacher prepares a pinyin worksheet for a lesson that contains 行, 重, 长, 还 and 得. Instead of opening a dictionary for every line, she pastes the worksheet, switches to polyphone-only mode, checks the orange characters and clicks the two readings she wants to change before copying the result into the teaching material.
2. A Chinese-as-a-second-language tutor builds a short reading passage for beginner learners. The tool marks the polyphonic characters that are likely to trip up a learner, keeps ordinary characters clean, and produces an inline version such as 银行（yín háng）门口 that can be pasted into a vocabulary handout.
3. An audiobook narrator checks a chapter that includes surnames, place names and characters with several common readings. The tool surfaces the ambiguous characters in orange, the narrator clicks through the alternatives, and the corrected pinyin list becomes a recording aid rather than a final authority.
4. A children's book editor receives a manuscript without pronunciation notes. The editor uses rare-character detection to find uncommon Hanzi, then exports an HTML ruby version for a web preview and a plain inline version for the copy editor who prefers parentheses.
5. A video producer proofreads narration for a history explainer. Names such as 仇, 解, 单 and place names such as 堡 are easy to misread on camera; the producer pastes the script, keeps the tool's suggestions where they are correct, overrides the rest, and exports a clean text file for the voice-over booth.
6. A language learner reads a short classical or newspaper passage and wants to see which characters are genuinely ambiguous rather than annotating every character. Switching to polyphone-only mode keeps the page readable while still exposing the cases that deserve a dictionary check.

How to Use

Step-by-step instructions

1. Paste Chinese text into the input box. Simplified and traditional characters, punctuation, line breaks, numbers and mixed Chinese-English text are all accepted. The tool counts Hanzi separately from punctuation and Latin characters.
2. Choose what to mark: polyphones only for the cleanest reading aid, rare characters when you are checking uncommon Hanzi, or all annotated characters when you want maximum coverage. The mode affects the display and the exported text, not the underlying analysis.
3. Choose the output format. Ruby mode produces HTML-style annotations with the pinyin above each character; inline mode produces text such as 重要（zhòng yào）. Ruby is better for a web page or a worksheet, while inline text is easier to paste into chat, subtitles or plain-text notes.
4. Review the orange characters. Click a highlighted character to cycle through its available readings. The counter shows how many polyphonic and rare characters were detected, and a separate missing list names characters for which the local dictionary has no pronunciation.
5. Copy the result or download it as a .txt file. Use the copy button for the format you are viewing, then paste into your document, or download the text and open it in your editor.
6. Proofread before publishing. The rule set covers common collocations, but names, classical Chinese, dialect-influenced text and unusual proper nouns can still need a human decision. The click-to-override control exists precisely for those cases.

How it works

Step-by-step instructions

1. Paste the source text. Put a paragraph, worksheet or script into the input area. Keep line breaks if you want the exported annotation to preserve them.
2. Pick a marking mode. Use polyphones only for a concise teaching aid, rare characters for editorial checks, or all when every annotated syllable is useful.
3. Select ruby or inline output. Ruby keeps the pinyin visually attached to each character; inline parentheses are easier to paste into plain-text tools.
4. Check and correct ambiguous readings. Scan the orange characters, click any wrong reading to cycle alternatives, and review the missing-character count before publishing.
5. Copy or download. Copy the displayed HTML or text, or download a .txt file for offline proofreading and recording notes.

How we compare

Why Choose Korelyy

What makes us better

1. Context matters: a 2-to-4 character window is checked against 456 curated collocation rules before a reading is chosen, which avoids the worst failures of naive per-character pinyin tables.
2. Human control is built in: every highlighted polyphone can be clicked to cycle through alternatives, so the tool assists a proofreader instead of pretending to replace one.
3. The page keeps private manuscripts local. Annotation runs in the browser and does not require an account, a file upload or a cloud processing queue.
4. Ruby and inline output cover two different jobs: HTML ruby for web pages and teaching materials, inline parentheses for chat, subtitles and plain-text scripts.
5. Rare-character detection and a missing-character list make gaps visible. When the local dictionary does not know a character, the tool says so instead of silently inventing a pronunciation.
