Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment and, the present invention is described in more detail with reference to accompanying drawing.
The present invention is provided with the translation function of communication speech and character on existing communication terminal, the conversion correspondence setting that is about to communication speech and character is on communication terminal, thereby the communication of read-write mode is adopted in realization.Because this translation function can adopt software setting on the existing hardware of existing communication terminal, so can not increase the volume of hardware cost and communication terminal, than prior art TYY equipment being external to communication equipment realizes adopting the communication of read-write mode to compare, reduce cost and be convenient for carrying, improved user's experience.
Do not possess speech capability and can't not carry out voice communication, but can carry out the communication of read-write mode by video or/and do not possess the user of hearing ability.In passing through the communication process of communication network, not possessing speech capability or/and do not possess the user of hearing ability can carry out real time communication by character.Therefore, the present invention is provided with the translation function of communication speech and character on existing communication terminal, adopt this translation function, communication speech input-output unit (as microphone/speaker) on the communication terminal can be removed, this user is not carried out the output or the input of voice, and only carry out the conversion of the communication speech that receives and character from communication network after, the communication speech that will be presented at after maybe will changing on the display screen of communication terminal is input in the communication network.
On specific implementation, the processor of communication terminal is input to the converting unit that communication terminal is provided with from the Wave data through demodulation that network receives as CPU control, by converting unit Wave data is converted to character; The processor of communication terminal also control will input character be input in the converting unit of communication terminal, by converting unit character conversion is Wave data after, obtain communication speech and send after the modulation again.
The two parties that adopts this communication mode of the present invention to communicate all adopts the communication terminal of the translation function with communication speech and character.
Fig. 1 is a realization read-write mode method for communicating flow chart provided by the invention, and its concrete steps are:
After step 101, communication terminal will carry out demodulation from the communication speech that communication network receives, obtain Wave data, show after Wave data is converted to character;
These two steps can be carried out in proper order, carry out simultaneously or first execution in step 102, and execution in step 101 again.
Fig. 2 is the communication terminal of employing read-write mode provided by the invention, comprises modem module, converting unit, input unit and display unit, wherein,
Modem module after being used for carrying out demodulation from communication network received communication voice, obtains Wave data and sends to converting unit; After converting unit reception Wave data is modulated, obtain communication speech, be transferred in the communication network;
Converting unit, the Wave data that is used for receiving from modem module is converted to character, sends to display unit; After will being Wave data from the character conversion that input unit receives, send to modem module;
Display unit is used to show the character that receives from converting unit;
Input unit is used for the character of input is sent to converting unit.
Wherein, display unit can be display screen, and input unit can be keyboard or the various connecting interface that input character can be provided.
In the present invention, can adopt the TTY technology in the communication speech of communication terminal setting and the translation function of character.To communication network transport communication voice the time, input unit by communication terminal, input character (character can be pinyin character, alphabetic character or numerical character), encoder in the TTY unit of She Zhiing is converted to the binary number coding with character by the Baudot coding schedule then, be Wave data by the audio frequency chorus device in the TTY unit with the binary number code conversion again, be transferred to communication network after being modulated to communication speech by modem module; When the communication speech of received communication Network Transmission, modem module is demodulated into Wave data with communication speech, is the binary number coding by the audio frequency resolver in the TTY unit of communication terminal with the Wave data analysis, the decoder of TTY unit is converted to character with the binary number coding by the Baudot coding schedule again, shows by display unit.Like this, not possessing speech capability just can not adopt read-write mode to communicate or/and do not possess the user of hearing ability.
In the present invention, because character comprises phonetic sound unit, punctuation mark and control character, and phonetic sound unit, punctuation mark and control character one have 60, so can use the binary system compiling that the Baudot coding schedule carries out character.In actual applications, can adopt the Baudot coding schedule of standard to communicate conversion between voice and the character.In the present invention, the definition frequency is that the sine wave of 1400 hertz (hz) is designated marker bit (mark), the definition frequency is that the sine wave of 1800hz is spare bits (space), the length of the sine wave of space and mark is defined as 22 milliseconds (ms) respectively, the respectively corresponding Baudot sign indicating number of each phonetic sound unit, punctuation mark or control character can be compiled as the combination of space and mark respectively.Store the corresponding relation of the Wave data of definition and binary number coding the encoder and the resolver of TTY unit into respectively or store in other unit of the encoder of TTY unit and the communication terminal that resolver can be visited, use when carrying out coding binary number encoder or parsing Wave data.
In the present invention, can also adopt other modes to define Wave data, and it is the Wave data of definition is corresponding with the binary number coding, but, must guarantee the mode of the definition Wave data that the employed communication terminal of communicating pair is adopted, and the corresponding relation between the Wave data of definition and the binary number coding is identical, like this, could guarantee the communication of communicating pair.
