PRONUNCIATION-SHOWING TYPE FACES

Abstract: Technical field: The application of linguistics to printing and publishing. Thechnical features: Chinese characters cannot show pronunciation; English cannot show pronunciation exactly. To know their pronunciation, we have to depend on phonetic symbols or phonetic letters (for Chinese, there are Chinese phonetic letters, both old and new; for English, there are many sets of symbols, of which the international phonetic symbols and Webster's are the most widely used). But these symbols or letters can only be used in dictionaires, not practical for textbooks or readers of any kind. Some Chinese publications have phonetic letters printed between lines, thus causing much trouble both to printing and reading, and so have failed to be widely accepted. The present Pronunciation-Showing Type Faces allow both Chinese characters and English words with self-pronunciation, characterized as follows: For Chinese characters, a set of stroke letters have been designed to represent the initial consonant, the "yunmu" and the tone; these stroke letters are set in Chinese characters so as to indicate their pronunciations. For English, a set of diacritics have been designed. The method of employing these diacritics is given below: The pronunciations of all letters and letter-combinations are classified into several categories; each category is provided with only one diacritic. A separate diacritic does not represent any particular sound. Only when it is placed above a particular letter can a particular sound be indicated. Uses: The invented type faces may be used to publish and print Chinese and English textbooks and readers of all kinds, which will facilitate a fine command of the pronunciation of the two languages and the memorizing of new words of English as well.

Description: PRONUNCIATION-SHOWING TYPE FACES . The gap between pronunciation and the writing system is a. pro blem common to all languages, especially to Chinese and Engli Chinese characters are not phonetic by origin. English, thoug using a basically phonetic alphabet, is nevertheless incapabl -5 αf showing pronunciation accurately. To learn writing systems αf such languages, phonetic transcriptions are indispensable. Transcriptions can only be applied in dictionaries, they are practical far readers of any kind. For example, some Chinese tεxt-bααks have transcriptions interlined, thus causing a lot 10 αf inconvenience in the proce.ss of printing and reading. By th end of the 19th century, .a number of Chinese scholars had al¬ ready made initial efforts towards the reform αf the tradition al Chinese writing system and the popularization αf new ones. During the last 30 years αr so, the reform has been firmly sup 15 ported throughout by the government. However, even now, it can not progress substantially. The distinguished British writer, Bernard Shaw, advocated energetically the replacement of the existing English writing system by a new alphabet and new ways αf spelling. He even dedicated part αf his legacy to the Eπg?- 20 lish writing-system reform. But so far, very little progress, if any, has been made. The experience αf all the writing-sys¬ tem reforms carried out whether in China , or in other coun¬ tries, shows that it is almost impassible far big, culturally- devεlαppεd countries to adopt a new writing system by wholly 25 abolishing the traditional one, because such a change would inevitably impose a change on the habits of millions αf people farmed through long years. This dαεs not mean, however, that πα change at all is admitted. There are two forms αf letters, the handwritten and the priπt- -50 εd. It is quite passible ta make appropriate alterations in the printed farm. Lots af diffεrεπt priπtεd farms have been in . vented, but they werε madε for aesthetic reasons αnly. Ours serve a different purpose. They arε iπtεπdεd tα show pronunci¬ ation, and are πamεd "prαnuπciatiαπ-shαwiπg typε faces". OMPI I« ENGLISH PRONONCIATION-SHOliJING TYPE FACES Draft I The Method of Showing Pronunciation with Classifying Diacritics 1. This invented system of diacritics allows a self- prαnuπciatiαn for all the English words by using a minimum number αf marks. Our principal method consists αf the following steps: / dividing a ward iπta vowel segment and consonant seg¬ ment; / classifying the pronunciations αf all vowel segments, each category is provided with one diacritic. A diacritic is_employed tα represent, instead αf an iπ- dividual sound, a category αf sounds. Only when it is placed above a particular letter can a particular sound be demonstrated. Therefore, the present set of diacrit- . ics is. dεsigπatεd classifying diacritic. Definition αf a vαwel segment: in a ward, several vowel le ters connected to each other form a vαwεl segrneπt(e.g.iπ th wards "look", "triangle", "bawl", "out' and "are", the con necting vowel letters "αo", "ia", "αw", "αu" and "are" are all vowel segments.) A single vαwεl lεttεr can alsα farm a vσwεl segment, (e.g. in the weirds "a", "but", "bεd" and "pig", thε single vσwεls "a", "u", "ε", "i" arε cαπsidεrεd to bε vαwel segmεπts as well.) All the six vαwel letters "a", "ε", "i", "y", "o", "u", and thε two nαπ-indεpeπdεπt vαwel * lettεrs "w" and "r" ("y", "w" and "r" fuπct-iαπ as consonants, too. . ), are passible raεmbεrs af a vαwεl sεgmεπt. A vαwεl ssgment αf only one lεttεr is called, a single- vowel lεttεr; a vαwεl segmεπt αf twα or mαrε lεttεrs is callεd vαwεl lεttεr-cσmbiπatiαπ. 2. The pronunciations of siπglε-vαwεl lεttεrs arε di¬ vided iπtα seven categαriεs. As fo r thε pronunciaitons αfvαwel lεttεr-cαmbiπatiαπs, there are the following three cases: 1/ a lεttεr-cαmbinatiαπ sαundεd by a single vowel, e.g. "or" is a letter combination sαundεd by thε single vowel to:]. 2/ a letter * combination sounded by a complex vowel, whi is the-pronunciation of only one αf its constituent mεm- bers, e.g. "αa", sounded by cam, [5U is the pronunciatio of the single letter "α",αne αf thε cαnstituεπt mεmbεrs α thε combination "oa", the other membεr "a" coπsideded si- lεnt. 3/ a lεttεr-cαmbiπatiαπ sαundεd by a complex -vowel, which is thε joint pronunciation αf all the constituent members αf the combination, e.g. "αi" sounded by [ • }_], CD13 -is the joint pronunciation αf "α" and "i", "o" considered to be read ill and "i" [ 1 ] . The pronunciations of letter-combinations in the first and sεcαπd casεs are classified in thε same way as thαse αf siπglε-vαwεl lεttεrs, and so they ars groupεd into the sam tablεs as given below: Tablε 1— ( 1 ) O PI v4 WIPO - 6 - Explanatory Mates ta Table 1: (1) Thε pronunciation αf a vαωel segment may be either a str.oπg vαωεl or a ωeak voωεl.

Voωel letters, uhen in a very small number αf ωords, having such an unusual pronunciation that they cannot be classified in Table 1 are crouinεd by a special diacritic: □ .

A lettεr-cαmbinatiαπ sounded as more than one vowel,all the constituent members being prαπouππεd, is called a com pound vowel'i e.g. "oi"nι] , "ia-'cia. . In a small number αf compound vowels, instead αf all the letters, same, at 35 least twα, αf them are prαπαuπced, ε.g. prayerc'pr β 3_ ,the "y" is silent. OMPI < * 7.

A weak com¬ pound vowel is unmarked except for thε case αf [iι_ . A weak compound vαwel, when bearing word stress in some cases, may be regarded as a strong compound vowel, ε.g.

There are two types αf compound vowels: complex vowels and successive vowels. Each compound vowel con¬ sists αf two parts: the frαnt and thε back. A compound vαwεl with a wεak vαwεl as its back part is πarπεd com¬ plex vowel. A compound vowel with a strong vowel as its back part is called succεssivε vowεl. "δu" soundεd by cju is included in complex vowels as well. A complex vαwεl is generally indicated by a diacritic above the front part whilε a succεssivε vowel is shown by a diacritic abovε the back part. fallowing arε diacritics to bε employed tα demonstrate compound vowels: ( m reprεsεnts ths two parts αf a com¬ pound vαwel.)

The pronunciations of successive voωels and their dia¬ critics are given beloω: Table 6: 12. The determination of the pronunciation of a succes ¬ sive vαωel depends thus an the knaωlεdgε of the pronunci¬ ation ' of every one αf its constituent letters. As is kπαωπ, every vαωel letter has a pair of pronunciations: a single voωel and a diphthong . As is pointed. out, a single voωel, as the pronunciation o thε front part, must be in its ωeak farm ωhilε , as the pronunciation αf thε back part , must be in its strαng farm. So a single voωel has a pair of forms: ωεak and 10 strong. Single voωels and their corresponding diphthongs , ωeak vαωels and their corresponding strong vαωεls are arrang¬ ed in pairs in the fσllαωiπg table: Table 7 : Explanatory /Vote tα Table 7 : ( 1 ) "e " has the long vαωel i : j in the place of a diph¬ thong . Table 7 is the k ey to thε determination of thε prαnuncia- tiαn of every letter in a successive voωel. For example: / exeunt: "eu" is a successive vαωel of tωα sounds, both "e" and "u" are sounded by a single vαωel. "e",as the front part, has the ωeak single vαωel cu as its pronun- 5 ciatiαπ; the back part "u" is sounded by the strong single vαωel C .

Every character retains its conventional strαkεs and struc¬ ture. Out of each character, three strokes are chosen tα repre¬ sent its initial consonant, "yuπmu" and tone. The pronunciation of a Chinese character,i.e. a Chinese- syllabl may bε divided into tωα parts: "shεπg-mu" and "yuπmu". The farme is an initial consonant; the latter a single αr compound vαwεl, sometimes ωith thε terminal consonant [n] or [ϊ]] in addition.Nat • εvery Chinεsε syllabls has an initial consonant. A syllable without the initial consonant- is called zεro-coπsαπant syllable Evεry Chiπεse syllablε,i.e. εvεry Chinese character,has " its own tone. 2. In genεral, the initial consonant is represented by a ver¬ tical stroke and thε "yuπmu" by a horizontal one. Lϋhεπ there is no suitable vertical αr horizontal stroke to bε chαsεπ , a slanting strαks,(a point strαkε is dεεmed in thε present sys¬ tem to bε a slanting strαkε as tiiεll,) may bε thε. substitute . A horizontal stroke can not rεprεsεπt the initial consonant, nor can a vertical stroke indicate thε "yuπmu". If a slanting strαkε is selected to rεprεsεπt thε initial consonant, thε aπ- gig betiεεn this slanting stroks and thε horizontal strαkε must bε aver 5 dεgrεεs.If a slanting stroke is selected to repre¬ sent the "yuπmu", thε angle between this slanting strαkε and the horizontal stroke must be under 5 degrees. Thε tone is represented by a stroke at the lower part on the right. Thε strαkεs that represent the initial consonant, the "yunmu" ' and thε tone are named "stroke lεttεrs". 3.
