Below is an introduction to "Jyutdict Android".

# 1. Overview

Jyutdict aims to collect contemporary local pronunciations, historical rime book phonological positions and reconstructions, while providing basic lookup functionality including character lookup and pronunciation lookup. In the future, rime lookup (search by phonological position) and word lookup, along with more character tables, will be added.

This application is the Android terminal version of Jyutdict. Since the server data is continuously being updated and some data has not yet been granted full publication rights by the original authors, this app still requires an internet connection to query the server. The server is not located within Mainland China, so queries may be slow — your patience is appreciated.

Additionally, given the app's target audience, if you have limited exposure to Cantonese phonology (for instance, if you are seeking pathways to learn Cantonese), this app may appear less than friendly.

# 2. General Character Table & Pan-Cantonese Character Table

This app uses the Extended Jyutping romanisation scheme (hereafter abbreviated as J++). The tone notation system is mostly illustrated in the Pan-Cantonese Tone Chart (opens new window).

The General Character Table (or "Common Speech Character Table") collects characters shared between Cantonese and Mandarin, or those with a relatively broad usage range.

Compared with Xiaoxuetang, the local character tables and rime book data here are provided by scholars from various localities within the Lingnaam Jyutjam community (see the list at the bottom of this page). As such, the local pronunciations have largely been self-reviewed by these contributors with modern strata removed.

For ease of comparison, each character entry is accompanied by its Guangyun phonological position (opens new window) and Polyhedron's Middle Chinese romanisation (opens new window), represented in the same manner as the "Chinese Character Pronunciations Across Time and Space" (opens new window) app.

General Character Table lookup

The upper-right portion of each character entry displays rime book readings: "分韻" refers to Fenyun Cuoyao (Chidu edition) (opens new window), and "英華" refers to Yinghua Fenyun Cuoyao (opens new window)

In the local pronunciation table, the locality name is followed by J++ and corresponding IPA (opens new window) notation. A fourth column occasionally appears as remarks, typically example words or explanations for characters with multiple readings.

When searching the General Character Table, you can look up multiple characters simultaneously, with automatic simplified-to-traditional conversion. Note, however, that searching more than ten characters at once is not supported, and support for compatibility characters is poor.

You can also use J++ to look up homophones across localities by directly entering a pronunciation and searching.

General Character Table pronunciation lookup

Tone markers can be omitted to indicate "tone-insensitive" search.

The Pan-Cantonese Character Table records characters that are more distinctively "Cantonese" compared to Mandarin, using Extended Jyutping (J++) to document their pronunciations across various localities. As of February 2021, over 3,000 entries had been collected.

While the table's definitions may not cover usages across all localities, and local records may be limited in precision by the contributors' knowledge, it at least allows these distinctive characters to be digitally preserved regardless of their status. It also helps roughly determine the usage range of a particular character and meaning. Conversely, local pronunciations can also provide more refined phonological information for the character head.

Pan-Cantonese Character Table lookup

The image above shows the result of looking up "睏" in the Pan-Cantonese Character Table. From top to bottom on the left are: the representative character, Unicode, other character forms (such as folk variant characters, pseudo-etymological characters), and the composite pronunciation. The actual display order may differ from the description here.

  • The "representative character" does not represent the etymological character (本字) or the orthodox character (正字). It is simply a relatively reasonable character chosen based on sound and meaning. We neither excessively pursue etymological characters, nor resist using folk characters with mouth radicals, nor insist on them being suitable for everyday typing.

  • The "composite pronunciation" does not represent the standard pronunciation (正音), nor does it represent historical readings. Rather, it is an artificial phonological system that merges the most raised elements from each selected locality. The composite pronunciation may inevitably contain occasional errors, so please refer extensively to the pronunciations marked for individual localities.

Accordingly, this app does not take any position requiring "standard pronunciation (正音)" or "orthodox characters (正字)".

The right side is divided into three parts: "Definition", "Local Pronunciations", and "Semantic Field":

  • When "Definition" contains bold text, only the bold portion should be attended to; other senses are typically taken from the current character head's explanations in classical dictionaries or the common language and do not imply that a particular locality possesses that sense.

  • The "Local Pronunciations" section colours each locality by default; colouring parameters can be adjusted in the settings interface. The closer the colours, the smaller the difference between the two localities, with hues roughly indicating subgroup affiliation. Pronunciations are likewise indicated in J++; italic text with a question mark "?" indicates uncertainty, while an underscore "_" indicates that the expression is considered unattested in that locality.

  • "Semantic Field" indicates the category of the character's meaning; only some characters are tagged with this.

Unlike the General Character Table, this table currently allows searching only one character at a time and no longer supports automatic simplified-to-traditional conversion.

Similarly, you can use J++ to search by composite pronunciation, or specify a particular locality's pronunciation from the dropdown list.

Pan-Cantonese Character Table pronunciation lookup

Note: Please do not equate the "composite pronunciation" with Guangzhou pronunciation or Hong Kong pronunciation. The rules for constructing the composite pronunciation are as follows:

Onsets:

z c s / zh ch sh: Distinguishes the Jing (精) and Zhao (照) series (Jing i merges with Shi (师) rime ii, so it is not further marked)

j / nj: Distinguishes the Ri (日) initial

Rimes:

aa / ae / e / i: ae is used wherever possible for Division II, depending on whether raising has occurred in places like Shunde; e in open-syllable rimes represents Xie (蟹) and Zhi (支) colloquial readings; i / e in checked-syllable (入声) rimes — see below

o / oe: oe represents Guo (果) Division III closed in the phonological system, as well as Guo open colloquial readings, depending on specific literary-colloquial patterns

ui / ooi / yi / yu: Distinguishes Kui (魁, ui), Sui (虽, ooi), Zhu (诸, yu) rimes; the split of the Jing series in Yu (遇, yi) depends on whether diphthongisation has occurred in each locality

im in ing / em en eng: Division III/IV literary-colloquial readings, favouring colloquial readings where possible, also considering the literary-colloquial ratio across localities (same principle applies to entering-tone rimes)

ing / yng: Geng (梗) and Zeng (曾) Division III/IV, depending on whether rounding has occurred in places like Watlam (same principle applies to entering-tone rimes)

ong / owng: Dang (宕) and Jiang (江), depending on whether rounding has occurred in places like Watlam (same principle applies to entering-tone rimes)

Tones:

Entering tone 4 / 6: Upper and lower Yang entering (阳入), depending on vowel length, primarily with reference to Watlam

Since the local pronunciation data is filled in voluntarily by native speakers from each locality and current manpower is limited, missing entries or errors for a given locality are common. Those interested in helping may contact us via the information at the bottom of this page.

In addition, you can also perform a "reverse definition search".

Pan-Cantonese Character Table reverse search

Due to technical reasons, reverse definition searches will also match example words and other positions, and the maximum number of results displayed per search is limited to 50, so you will need to choose appropriate keywords yourself.

Regardless of the search method used, as long as a character entry has a character head, you can copy it by short-pressing or long-pressing.

# 3.4 FAQ

Q1. Why is J++ necessary? / Why not just use IPA?

In practice, J++ is used in three places: 1. local pronunciation display; 2. lookup by pronunciation; 3. the Pan-Cantonese Table. If only IPA were used, on the one hand the barrier to entry would be raised, and on the other hand data entry work everywhere would become more cumbersome. Moreover, the Yue phonological system is relatively uniform, and the commonly used Extended Jyutping has not changed drastically from the original Jyutping — the learning cost is low. Furthermore, narrow transcription in IPA is still used for detailed recording; while this more accurately captures local pronunciations, it also weakens the connections between readings from different places. Hence Jyutping is supplemented, which also carries tone markers to indicate tone categories.

(Note: Not all localities have narrow IPA transcriptions, and even where broad IPA is used, it may not be sufficiently adequate. This is constrained by whether conditions allow analysis of the actual local pronunciations, compounded by the accent biases of the character table contributors — one of the reasons why relying solely on IPA is not feasible.)

Q2. Why so few localities? / Why are they all from xx?

See below.

Q3. Errors in the data? / Can I provide a local character table? / Interested in contributing to the Pan-Cantonese Table / Have suggestions?

You are welcome to contact us and provide character tables.

Q4. What is the significance of the composite pronunciation in the Pan-Cantonese Table?

The Pan-Cantonese (Character) Table is built on the concept of synchronic comparison of meanings across local pronunciations. In striving to make it a broad, distinctive, Pan-Cantonese-oriented database, we inevitably face numerous practical data processing challenges, such as sorting electronic data, filtering, cross-locality searching, and so on. It is precisely to facilitate these functions that the table provides the so-called subjectively constructed "Pan-Cantonese Composite Pronunciation", whose materials are rooted in historical Yue dictionaries and the raised phonemes of various local pronunciations. This "composite pronunciation" is not recommended for use as an actual common pronunciation, and its rules will change with the expansion of data sources and updates to Yue phonological theory.

Q5. Other versions?

The Web version is available.

Q6. "Speak Mandarin, be a civilised person" / "Guangzhou speech is the most standard Cantonese" / The Yue language police?

Oh.
