Description
Technical field
The present invention relates to a kind of Chinese character input method, relate in particular to a kind of based on the method for sound sign indicating number through digital keyboard input character.
Background technology
Along with smart mobile phone application software and the fast development in recent years of 3g network; Mobile phone has become a part inseparable in our daily life; Yet the input method that can on cell phone platform, realize word-level Chinese character input at present also be not a lot of and function also limited, therefore exploitation has very strong practical application meaning to the whole sentence level Chinese character entering technique of cell phone platform.
The Chinese character input can be divided into word, speech, three kinds of input modes of statement from the base unit of input.Wherein words input characteristics are to serve as basic input unit with word or speech, need selected the imputting Chinese characters of words again by the user by behind user's input coding.Statement input characteristics are to serve as basic input unit with phrase or sentence, have input process and need not user's participle, high input speed, easy to learn, and a kind of desirable imputting Chinese characters of advantage such as compatible words input.Will on mobile phone, realize Chinese sentence input, the bond number that main difficult point is exactly a cell phone keyboard lacks a lot than the pc keyboard, and the T9 spelling input method that uses with present main flow is example; Phonetic alphabet are successively set on the digital keys " 2～9 ", and the corresponding a plurality of phonetic alphabet of numerical key are such as three phonetic alphabet of numerical key " 2 " correspondence " a, b, c "; So directly input digit phonetic has caused string number string correspondence to go here and there pinyin string more, and the number of syllables that these pinyin string also possibly comprise is all inequality; For example, the pairing Chinese phonetic alphabet of numeric string " 7426 " can be: piao, pian, qian, qiao, shan, these 6 single syllable phonetics of shao, and the pairing Chinese phonetic alphabet syllable number of some number pinyin is then unequal; For example; 248264, the corresponding Chinese phonetic alphabet is chuang; Citang, aitani etc.This situation is in phrase and whole sentence input based on mobile phone; The numeric string of input is long more; Pairing Chinese phonetic alphabet number and possible different syllable number are also just many more, and this causes a series of insoluble problems such as too high, the possible candidate's sentence of computation complexity is too much with regard to giving by the Chinese phonetic alphabet to the later stage conversion of whole sentence sentence.
On numeric keypad, use non-phonetic coding scheme or double spelling coding scheme, then be difficult to memory, for want of user base and can not get widespread use.Therefore; On the basis of existing numeric keypad phonetic code input method; Do not influencing under the prerequisite of original user's input habit as far as possible; Effectively reducing the repetition rate of coding that numeric string is expressed pinyin string, is the Chinese character input speed that improves on the numeric keypad, realizes the problem of the required solution of whole sentence input on the numeric keypad.
Summary of the invention
The object of the invention provides a kind of digital keyboard Chinese character input method based on the sound sign indicating number; Through the adjustment that button is provided with; On the basis that does not influence original phonetic input habit; Reduce the quantity of the corresponding Chinese phonetic alphabet string of same numeric string,, create conditions for realizing whole sentence input to improve Chinese character input speed.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of digital keyboard Chinese character input method based on the sound sign indicating number; Be used on the keyboard that comprises digital keys " 0～9 ", carrying out the Chinese character input, be distributed with the letter of forming initial consonant and simple or compound vowel of a Chinese syllable on the said digital keys " 0～9 ";
The letter that is applied to the phonetic simple or compound vowel of a Chinese syllable is divided into 7 groups; Be respectively; First group " a ", second group " o ", the 3rd group " e ", the 4th group " i ", the 5th group " u/v ", the 6th group " n " and the 7th group " g ", these 7 groups of letters are distributed on 7 different keys;
Other letter that only is used for the phonetic initial consonant is divided into 8 groups, is distributed on the digital keys " 2～9 ";
Import the letter that is comprised in initial consonant and the simple or compound vowel of a Chinese syllable of Chinese character successively, realize the input of Chinese character on numeric keypad.
The formation characteristics of the Chinese phonetic alphabet are analyzed and can be found; Except that single vowel phonetic; The phonetic of each Chinese character all is made up of initial consonant and simple or compound vowel of a Chinese syllable, and the simple or compound vowel of a Chinese syllable of each phonetic all has a vowel at least or have at least a vowel to add n or ng forms.In the technique scheme, will be divided into 7 groups, be distributed on 7 different keys the letter that is applied to the phonetic simple or compound vowel of a Chinese syllable; Thereby; At the input letter (u and v can not occur simultaneously, can judge according to initial consonant) that each digital keys can only corresponding 7 phonetic alphabet during simple or compound vowel of a Chinese syllable, this just can solve Serial No. in the pinyin sequence conversion; The problem of the legal simple or compound vowel of a Chinese syllable of the corresponding many strings of string number possibility reaches the purpose that significantly reduces pinyin combinations quantity.
Optimized technical scheme; Said button to the letter that is applied to the phonetic simple or compound vowel of a Chinese syllable is distributed as, and " a " is distributed in that digital keys " 2 " is gone up, " o " is distributed in that digital keys " 0 " is gone up, " e " is distributed in that digital keys " 3 " is gone up, " i " is distributed in that digital keys " 1 " is gone up, " u/v " is distributed in that digital keys " 8 " is gone up, " n " is distributed in that digital keys " 6 " is gone up, " g " is distributed on the digital keys " 4 ".
The said button that only is used for the letter of phonetic initial consonant is distributed as, and " bc " is distributed in that digital keys " 2 " is gone up, " df " is distributed in that digital keys " 3 " is gone up, " h " is distributed in that digital keys " 4 " is gone up, " jkl " is distributed in that digital keys " 5 " is gone up, " m " is distributed in that digital keys " 6 " is gone up, " pqrs " is distributed in that digital keys " 7 " is gone up, " t " is distributed in that digital keys " 8 " is gone up, " wxyz " is distributed on the digital keys " 9 ".
In the above-mentioned preferred version, not only little to the modification of phonetic alphabet layout of the prior art, and the letter " i " of adjustment and numeral " 1 "; Letter " o " can also play the nature corresponding relationship with digital " 0 " on font; Therefore, user's phonetic input habit changes less, is easy to memory.And letter " i " and " gh " common numbers key " 4 " in original number pinyin scheme, cause numerical key " 4 " and numerical key " 2 ", " 7 " to wait " 24 " of making up, " 74 " Serial No. appears at the phonetic head both can be converted into a single syllable phonetic " ci "; Also can be converted into the initial consonant " ch " in the phonetic; For example, numeric string " 248264 " can convert chuang into; Citang, three kinds of pinyin sequences that do not wait syllable number of aitani.Same letter " o " and " mn " common numbers key " 6 " cause numerical key " 6 " and numerical key " 4 " composition " 64 " Serial No., and the afterbody that appears at phonetic both can be converted into a single syllable phonetic " ni " or " mi "; Also can be converted into the consonant " ng " that ends up in the phonetic initial consonant, for example numeric string " 3264 " can convert dang into; Fang, dani, dami; Fani, two kinds of pinyin sequences that do not wait syllable number of fami.More than these often are combined in the actual input and occur; The pinyin sequence that is easy to cause the string number sequence will corresponding many strings maybe syllable number not wait; And in numeric keypad phonetic plan of the present invention; Arrive alphabetical " i " layout on the numerical key " 1 ", to numerical key " 0 ", this just eliminates the problem that in conversion, may produce multiple different number of syllables owing to above combination of numbers letter " o " layout.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1. the present invention's letter that will be used for simple or compound vowel of a Chinese syllable is divided into 7 groups; Be separately positioned on 7 different digital keys; Solved that i and g, n and o lay respectively at a large amount of coincident code problem that cause on the same key in the prior art, reduced the coincident code problem of the corresponding phonetic alphabet string of numeric string in the input; In conjunction with judgement, can further realize whole sentence input for initial consonant and simple or compound vowel of a Chinese syllable;
2. employing the present invention, user's phonetic input habit changes less, is easy to memory, thereby helps applying.
