Abstract
A Chinese character input technique for a telephone set utilizes the twelve keys on the telephone set to input Chinese characters, and does not require the input of a character converting marker, such as the '*' marker. After the user inputs key signals through the keypad portion of the telephone set, reference is made to a phonetic table to convert the same into phonetic markers. After the phonetic markers for a first converted character have been inputted, and when the second phonetic marker for a succeeding character is inputted, automatic reference to a sound-to-character converting dictionary is made to convert the first character phonetic markers into a character. As such, a minimum number of key inputs is needed to input Chinese characters in a telephone set to dramatically increase the Chinese character input efficiency in the telephone set.
Description
The present invention relates to a kind of Chinese input unit, it utilizes the keyboard of regular phone machine in the phonetic symbol mode telephone set to be imported in Chinese character.
Because the obtained progress of the communication technology, phone has become necessary tool in our modern life.Normally used keyboard comprises 12 keys (for example, 0 to 9, * and #) in the telephone set, is used to import callee's telephone number to set up communication by communication network.Obtained progress makes recently the possibility that is combined into of liquid crystal display and telephone set in electronics and demonstration field, so the user can accurately verify the telephone number of its input.In addition, telephone set can hold a bigger memory device now, as random asccess memory or read-only memory, therefore allows the realization of a short message transfer function or database function.For example, by importing a surname, just can realize that automatic search to database is to find out telephone number corresponding as search name.Therefore, how effectively to use telephone set to come input information or make up the important problem that a database has become consideration.
Input character is at present primarily by using keyboard to realize in computer.Therefore, a lot of relevant methods have been suggested.The method comparatively approaching with telephone keyboard is to utilize the Chinese character input method of the numeric keypad of computer, for example be published in the Taiwan patent gazette and announce the numerical key Chinese speech input method in No. 73889 and be published in the Taiwan patent gazette and announce method in No. 73890, these two kinds of methods all are to import Chinese character by their mandarin Chinese pronunciations in the Rome western language system that uses numerical key.In above two patent announcements, mandarin Chinese speech mark is assigned to eight keys of the numeric keypad on keyboard the right, and for example, " 1 " arrives the numerical key of " 8 ", is used to import Chinese character.
In addition, the Taiwan patent gazette is announced No. 119811 and is disclosed a kind of input method based on stroke, wherein, uses 16 radicals to import Chinese character.At present, the Chinese MCI in Taiwan and Academia Sinica just cooperation change into 12 characters input methods based on radical to existing method, are used for the Chinese character input method of telephone set of future generation.
Traditional method and apparatus of input character has been disclosed in the Japanese patent gazette (putting down) 4-31615 number in mobile phone.Fig. 7 shows the system block diagram of an one embodiment.As shown in Figure 7, reference number 34 is represented a keyboard portion, and it comprises numerical key (0 to 9) and relevant function key, for example character conversion key.Reference number 36 is represented a display part, is used for character display or numeral.Reference number 38 is represented a timer.Reference number 40 is represented the pattern display part of a mobile phone.Reference number 32 is represented a control section, is used for controlling the signal of the different piece of telephone set.Reference number 42 represents one to select part, is used for selecting between Japanese ideogram and alphanumeric character.Reference number 44 is represented the display-memory of a demonstration usefulness.Reference number 46 is represented a key signals/Japanese ideogram conversion index part, is used for the key signals of input is converted to the Japanese ideogram symbol.Reference number 48 is represented a key signals-alphanumeric character conversion index part, is used for input key signal is converted to alphanumeric character.Reference number 50 is represented a character conversion part, is used for the Japanese ideogram symbol is converted to Japanese.On behalf of homophone, reference number 52 judge part, be used for have same pronunciation and the different Japanese character of meaning is judged.
At an above-mentioned embodiment who is used for traditional characters input method of telephone set, ten keys given respectively in ten consonants of Japanese, 0-9 for example, as shown in Figure 8.According to the number of times that a key is pressed, select one among five Japanese vowels to produce required set with Japanese alphabet symbol.For voiced sound in the Japanese and half-voiced, use " * " and " # " key to select them.After a phonic symbol string is transfused to into, must convert this phonic symbol string to required Japanese character by operational character conversion portion 50.For example, " 3333 " are transfused in order to obtaining Japanese phonic symbol " su ", and " 3333# is transfused in order to obtaining Japanese phonic symbol " zu ", and " 222 " are transfused in order to obtain Japanese phonic symbol " ki ".Therefore, behind character conversion part 50 end of operations, Japanese character " Suzuki " has just obtained.
The shortcoming of the above-mentioned prior art of mentioning is:
1. use the Chinese character input method of numerical key only to utilize ten keys, the numerical key of 0-9 for example, and do not utilize 12 keys.To print off a lot of Chinese speech marks on the surface of each key, therefore bring inconvenience to the user.
2. use the input method of character radical,, before using them, need one long period to grasp, and be easy to cause burden to the user for example based on the input method of stroke.
3. have only English and Japanese input method to use at present, and do not use Chinese character input method in the present telephone set.
4. in general each key in the telephone set all disposes a plurality of phonic symbols.Before next phonic symbol is transfused to, have no idea to verify the current phonic symbol of importing.Therefore, the user must the operational character conversion key verifies the accuracy of the phonic symbol of being imported, and the beginning character conversion.So, the user not only must operate many keys and come input character, and character conversion is impossible automatically.For example, during desire input " pine " word, being used for telephone set is a word multitone, so even be input to " g " of " song ", system can't judge whether automatically that also the character of importing finishes.
Therefore, an object of the present invention is to provide a Chinese input unit, it utilizes the keyboard of general telephone set to use phonetic symbol to import Chinese character in telephone set, and it can overcome the above-mentioned shortcoming that links with traditional characters input method above-mentioned.
Correspondingly, Chinese input unit of the present invention is adapted at using in the telephone set, and it comprises:
Key signals voice contrast storage area is used for the storage key signal and the corresponding phonetic symbol of the index done according to a certain specific operated number of times of key;
A dictionary storage area is used to store the Chinese of the index that the frequency used according to mandarin Chinese speech mark and their does;
An importation makes the user can input key signal;
A display part is used to show that one just is being carried out the phonetic symbol string of processing and the relevant character that is converted;
A buffering area is used for temporarily storing register value, just processed phonetic symbol string and the character that is converted accordingly;
A key signals conversion portion connects and search key signal speech contrast storage area key signals and corresponding phonetic symbol of the operated number of times of specific key to obtain and to import.
A character conversion part connects and the reference character dictionary storage area becomes a character string to change this phonetic symbol, and it is to use the phonetic symbol string of importing as index name to realize by voice-character conversion method; With
A control section that is connected to importation, buffering area, display part, key signals conversion portion and character conversion part, key signals that the control section reception is imported by the importation and the content in the reference buffer district, control section operating key conversion of signals part and character conversion part are in order to handle and conversion is transfused to the into key signals of character string and the phonetic symbol string that is not converted, and control section is preserved the intermediate treatment result and controlled display part and assign to show this character string and this phonetic symbol string that is not converted in buffering area.
Based on the formation that is used for the Chinese input unit of telephone set according to the present invention, after control section receives the key signals imported by the importation and index button signal value and the number of operations from the key of buffering area, by mating and calculating the operand of adjusting this key.When contrasting storage area with after obtaining corresponding phonetic symbol, a phonetic symbol string and a character string just from buffering area, have been retrieved with reference to these key signals voice.This phonetic symbol that retrieves was ganged up the key signals converter section and is assigned to upgrade, and this phonetic symbol string and character string are provided for the character conversion part.Character conversion partial reference dictionary storage part assigns to obtain a character string and a phonetic symbol string that is not converted, and buffering area is updated with this key signals, key operation number of times, the phonetic symbol string that is not converted, character string and phonetic symbol string.Then, this character string and the phonetic symbol string that is not converted are displayed in the display part.

If being judged to be among the step S285 be, flow process just enters step S287, and there, the length of phonetic symbol string is used to upgrade transition flag register 710.Execution in step S289 then.
If being judged to be among the step S290 is that flow process just automatically enters step S289.
If whether the judgement among the step S295, flow process also automatically enters step S289.
With reference now to the operation of the process chart among Fig. 3, be described key signals conversion portion 500.In step S301, control section 400 provides key signals (i) and key operation number (j).Then, in step S305, use key signals (i) as an index name, reference key signal speech contrast storage area 550 is to obtain this phonetic symbol A[k].Then, whether execution in step S310 judgment value " j " is greater than P.If not, export corresponding phonetic symbol A[j with regard to execution in step S320] and value " j ".Otherwise before flow process entered step S320, in step S315, determined value " j " was replaced by the remainder of (j-1)/P.
With reference now to the operation of the process chart among Fig. 4, be described character conversion part 600.In step S401, behind phonetic symbol string of input, in step S405, from the dictionary storage area 650 that has higher-priority than long sentence, obtain a character string " q " and a phonetic symbol number " n " that is not converted.Flow process then enters among the step S410 and goes, and there, character string " q " and the phonetic symbol number " n " that is not converted are transmitted away.
The processing example of the following Chinese character input that is used for telephone set is used to illustrate the operation of most preferred embodiment.For example, when the telephone keypad that uses Rome western language system was used to import Chinese character " Panasonic ", the content in the voice in the buffering area and character string and the different register was with following variation:
